Background/Objectives: Conventional periodontal treatment for patients with diabetes has shown promising results, primarily focusing on glycated hemoglobin (HbA1c) levels as an endpoint measure. The properties of hyaluronic acid (HA) have been harnessed in various periodontal therapies, and it is a promising agent also in a non-surgical approach. The aim of this clinical trial was to assess the efficacy of hyaluronic acid in a local adjunctive non-surgical treatment for periodontitis in patients with type 2 diabetes. Methods: Eighty adult participants with well-controlled type 2 diabetes (HbA1c 7% (53 mmol/mol) or less) took part in the trial. The clinical parameters of periodontitis as well as the glycated hemoglobin (HbA1c) levels were evaluated, and an analysis of the potential differences between the control (placebo) and intervention (HA) groups was performed. Results/Conclusions: A decrease in all the clinical values of periodontitis after treatment was observed in the vast majority of patients in both groups. Differences in the clinical parameters were observed 12 weeks after the intervention between the patients in the placebo and HA therapy groups. Bleeding on probing (BoP) was reduced in the control group to 15–25% and was approximately 5.5% more in the intervention group (9.5–18.25%). The clinical attachment level (CAL) decreased 1 mm more in the HA therapy group (1–2 mm) than in the no adjunctive treatment group (2–3 mm). The probing depth (PD) was reduced similarly in both groups (3–3.75 mm). Due to the bilateral relationship between diabetes and periodontitis, healthcare professionals seek advancements in managing periodontal inflammation. The results of this study indicate that non-surgical periodontal treatment with HA as an adjunctive agent is worth considering in the therapy for patients with diabetes. [ABSTRACT FROM AUTHOR]

Abstract Aim The current umbrella review aimed to summarize the effect of erbium-doped yttrium aluminum garnet (Er: YAG) laser adjunct with the conventional non-surgical periodontal treatment which was evidenced from available systematic reviews. Methods An extensive literature search was piloted by two independent reviewers in the PubMed, Scopus, Science Direct, and Google Scholar databases. The search was limited to the English language from 2011 to 2023 years. The methodological quality of systematic reviews 2 (AMSTAR 2) guideline was followed to evaluate the risk of bias for the selected studies. Cohen’s kappa statistic was implemented to evaluate the level of agreement to assess the risk of bias in the selected studies. Results A total of 472 studies were initially identified. After removing the duplicates and screening, a total of four studies were selected for the current overview. Based on the quality assessment tool, each study scored as high, moderate, low, and critically low-quality study following AMSTAR 2 tool. Inter-rater reliability by Cohen’s Kappa statistics showed near-perfect agreement (0.95) between the two reviewers. Conclusion Even though weak evidence of effectiveness was observed for Er: YAG laser application in non-surgical periodontal treatment, the clinical benefits are still lacking.

Abstract Background Periodontal Disease (PD) associated with Type 2 Diabetes Mellitus (T2DM) is a chronic condition that affects the oral cavity of people living with T2DM. The mechanisms of the interaction between type 2 Diabetes Mellitus and Periodontal diseases are complex and involve multiple pathophysiological pathways related to the systemic inflammatory process and oxidative stress. Non-surgical periodontal treatment (NSTP) is considered the standard for the management of this disease; however, patients with systemic conditions such as type 2 Diabetes Mellitus do not seem to respond adequately. For this reason, the use of complementary treatments has been suggested to support non-surgical periodontal treatment to reduce the clinical consequences of the disease and improve the systemic conditions of the patient. The use of zinc gluconate and magnesium oxide as an adjunct to non-surgical periodontal treatment and its effects on periodontal clinical features and oxidative stress in patients with Periodontal diseases -type 2 Diabetes Mellitus is poorly understood. Methods A quasi-experimental study was performed in patients with periodontal diseases associated with T2DM. Initially, 45 subjects who met the selection criteria were included. 19 were assigned to a control group [non-surgical periodontal treatment] and 20 to the experimental group (non-surgical periodontal treatment + 500 mg of magnesium oxide and 50 mg of zinc gluconate for oral supplementation for 30 days) and the data of 6 patients were eliminated. Sociodemographic characteristics, physiological factors, biochemical parameters, and clinical features of periodontal diseases were assessed. Results In this research a change in periodontal clinical characteristics was observed, which has been associated with disease remission. Additionally, a shift in MDA levels was presented for both groups. Furthermore, the supplementation group showed an increase in antioxidant enzymes when compared to the group that only received NSPT. Conclusion The use of Zinc gluconate and magnesium oxide can serve as a complementary treatment to non-surgical periodontal treatment, that supports the remission of PD as a result of regulation-reduction of oxidative biomarkers and increase in antioxidant enzymes activity.

Background: Periodontitis is associated with increased oxidative stress, which may impair treatment outcomes. Ozone therapy has shown promise in reducing oxidative stress and improving periodontal health. This study examined the impact of adjunctive gaseous ozone administration on salivary oxidative stress markers in patients with periodontitis stages II–IV and grades A–C undergoing non-surgical periodontal treatment (NSPT). Methods: Ninety patients with periodontitis were randomly allocated to either the test group (NSPT with gaseous ozone administration) or the control group (NSPT alone) using computer-generated randomization. The OzoneDTA system was used to deliver ozone at 2100 ppm for 60 s per site once weekly for 4 weeks. Clinical periodontal parameters (probing depth [PD], clinical attachment level [CAL], plaque index [PI], gingival index [GI]) and salivary oxidative stress markers (malondialdehyde [MDA], total antioxidant capacity [TAC], superoxide dismutase [SOD]) were assessed by blinded examiners at baseline, 3, and 6 months post-treatment. Results: Mixed ANOVA revealed significant three-way interactions between time, treatment, and stage or grade for clinical and biochemical measures (p < 0.001). The test group exhibited significant improvements in TAC (mean difference: 0.45 ± 0.12 mmol/L, p = 0.002), MDA (−0.38 ± 0.09 nmol/mL, p = 0.001), and SOD (65 ± 18 U/mL, p < 0.001) compared with the control group, with more pronounced effects in stages III and IV. Large effect sizes (Cohen's d > 0.8) were observed for the test group between baseline and 6 months for all markers. Conclusions: Gaseous ozone administration as an adjunct to NSPT can effectively improve clinical periodontal parameters and salivary oxidative stress markers, particularly in stages III and IV periodontitis. The enhanced outcomes may be attributed to ozone's antimicrobial and immunomodulatory properties, which synergistically reduce oxidative stress and promote periodontal healing.

Objectives: This pilot randomized controlled clinical trial compares the clinical outcome obtained in persistent periodontal pockets during 9-month follow-up of supportive periodontal step 4 treatment performed by either combining subgingival instrumentation with adjunctively used sodium hypochlorite/amino acid gel and crosslinked hyaluronic acid (xHyA) or subgingival instrumentation alone. Materials and methods: Study protocol is registered under NCT06438354 at Clinicaltrials.gov. Patients seeking further therapy after completed step 2 non-surgical periodontal treatment underwent either repeated subgingival instrumentation with adjunctive application of sodium hypochlorite/amino acid gel and crosslinked hyaluronic acid (group A) or repeated subgingival instrumentation alone (group B). One calibrated investigator performed the treatment sequence in both groups accordingly. Subgingival instrumentation of the residual pockets was carried out under local anaesthesia using hand- and ultrasonic instruments, as well as air polishing in both groups. Patients were instructed to continue oral hygiene without any restriction. At 3-month re-evaluation treatment was repeated accordingly at sites with persistent 5 mm probing depth and BoP +. Clinical attachment level (CAL), pocket probing depth (PPD), gingival recession (GR), and bleeding on probing (BoP) were recorded at baseline (T1), 3- (T2) and 9-month (T3) post-op, with CAL as a primary outcome measure. Results: In total 52 patients (20 females and 32 males, mean age 58.4 ± 2.4 years) presenting with 1448 sites which required further periodontal treatment were enrolled. Both groups exhibited homogeneity in terms of age, gender, smoking habit, initial number of sites, and BOP. At 9-month evaluation, PD reduction and CAL gain showed significant differences between the test and control group, favouring the adjunctive treatment. GR tended to exhibit more recovery in the test group compared to the control group. Although BOP frequency effectively reduced in both groups, there was no statistically significant difference between the two groups. Conclusion: Within the limits of the study, the present data indicates that, during subgingival instrumentation of persistent pockets, the adjunctive usage of sodium hypochlorite/amino acid gel and xHyA sufficiently improves the clinical outcomes. The continuous improvement of CAL in association with the GR scores observed in group A, indicates that sites subjected to adjunctive treatment may indicate a tendency for a regenerative response to treatment within the 9-month follow-up period.

Background: Periodontitis and diabetes mellitus (DM) exhibit a bidirectional relationship and are globally significant systemic chronic conditions. The utilization of antibiotics alongside non-surgical periodontal treatment (NSPT) has been a subject of investigation in numerous clinical studies involving human subjects. Thus, the objective of this systematic review is to address the following question: "What is the efficacy of scaling and root planing (SRP) associated with antimicrobials in patients with type 2 DM and periodontitis?". Methods: A systematic review of the literature was conducted encompassing databases such as MEDLINE/PubMed, Scopus, and Web of Science up to July 2024. Additionally, alerts were configured to capture studies published from the initial search until manuscript submission. Randomized clinical trials assessing clinical periodontal parameters in DM patients undergoing SRP and receiving either topical or systemic antibiotics were compared against a control group (SRP only). Two investigators independently screened articles, extracted data, and evaluated their quality. The selection process, study characteristics, risk of bias, impact of antibiotics on clinical parameters, and certainty of evidence were elucidated in both textual and tabular formats. Meta-analysis was performed separately with forest plots generated for treatment modalities, period of evaluation, and type of antibiotics used. Results: Following the analysis of abstracts and full articles, a total of 30 randomized clinical trials were incorporated into this review, comprising 9 studies on the association of topical antibiotics and 21 studies on systemic antibiotic administration. The principal periodontal parameters assessed included probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), and bleeding on probing (BoP). Conclusions: Analysis of the results led to the conclusion that adjunctive periodontal treatment with either topical or systemic antibiotics confers subtle clinical benefits. Nevertheless, owing to the heightened emergence of resistant bacteria and potential side effects, the use of antibiotic therapy in periodontal treatment should be judiciously administered.

Purpose: The present study assessed the efficacy of 0.12% chlorhexidine (CHX) and Salvadora persica-based mouthwashes (SPM) in reducing oral Candida carriage (OCC) and periodontal inflammation in cigarette smokers and non-smokers after non-surgical periodontal treatment (NSPT). Materials and Methods: Self-reported cigarette smokers and non-smokers with periodontal inflammation as well as nonsmokers with a healthy periodontal status were included. NSPT was performed in all participants. Based on the type of mouthwash, participants were randomly divided into three groups as follows: group 1: CHX; group 2: SPM; and group 3: distilled water (ddH2O) with mint flavour (control group). Clinical attachment loss (CAL), plaque index (PI), gingival index (GI), probing depth (PD), and marginal bone loss (MBL) were measured. Clinical periodontal parameters were re-assessed at a 6-week follow-up. Oral yeast samples were collected and identified using a concentrated oral-rinse culture technique and PCR, respectively. Clinical and laboratory-based investigations were done at baseline and after six weeks. Statistical significance was set at p < 0.05. Results: At baseline, PI, MBL, PD and CAL were comparable in all participants. None of the patients had periodontitis at baseline. Post-operatively, CHX and SPM were more effective in reducing PI (p < 0.01), GI (p < 0.01) and PD (p < 0.01) in nonsmokers than in the control group. The OCC was statistically significantly higher among smokers compared with nonsmokers at baseline. At the 6-month follow-up, CHX was more effective than SPM in reducing OCC in non-smokers (p < 0.01). At the 6-week follow-up, there was no difference in OCC among cigarette smokers regardless of the type of mouthwash prescribed postoperatively. Conclusion: In cigarette smokers and non-smokers, CHX and SPM are effective in reducing periodontal soft-tissue inflammation after NSPT. Post-operative use of CHX is more effective than SPM in reducing OCC. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to explore the effect of nonsurgical periodontal treatment on Galectin-1 and -3 GCF levels in gingivitis and periodontitis stage III compared to periodontally healthy individuals, to determine whether they could serve as diagnostic markers / therapeutic targets for periodontitis and revealing their possible role in periodontal disease. Materials and methods: Forty-five systemically healthy participants were included and equally subdivided into three groups: gingivitis, periodontitis (stage III), and a periodontally healthy control group. The clinical parameters were recorded. Galectin-1 and -3 GCF levels were evaluated (before and after non-surgical treatment for periodontitis) using an enzyme linked immune-sorbent assay (ELISA) kit. Receiver operating characteristic (ROC) curve was performed to reveal sensitivity, specificity, predictive value, and diagnostic accuracy of both markers. Results: The study showed statistical significance between different groups regarding Galectin-3 with higher values in periodontitis and the lowest values in healthy control. Also, Galectin-1 was significantly higher in the periodontitis/gingivitis groups than in the control group. Moreover, non-surgical periodontal treatment in periodontitis patients caused a statistical reduction in clinical parameters and biomarkers. ROC analysis revealed excellent diagnostic ability of both biomarkers in discriminating periodontitis/gingivitis against healthy individuals (100% diagnostic accuracy for Galectin-1 and 93% for Galectin-3, AUC > 0.9) and acceptable diagnostic ability between periodontitis participants against gingivitis (73% diagnostic accuracy for Gal-1 and 80% for Gal-3, AUC > 0.7). Conclusions: Both Galectin-1 and Galectin-3 seem to have outstanding diagnostic accuracy for the identification of periodontal disease, an acceptable ability to measure periodontal disease activity and the severity of inflammatory status. Additionally, they could serve as therapeutic targets to monitor treatment efficiency. Clinicaltrial.gov registration number: (NCT06038812). [ABSTRACT FROM AUTHOR]

Background: Type 2 diabetes mellitus (T2DM) has been considered by many studies to have a bidirectional relationship with periodontitis. This systematic review and network meta‐analysis aimed to investigate the impact of different states of T2DM when stratified by baseline HbA1c on the clinical outcomes of non‐surgical periodontal treatment (NSPT). Methods: This study followed the Preferred Reporting Items for Meta‐Analyses (PRISMA) guidelines and involved an electronic literature search (from inception to the 2nd of January 2023). The study included at least two groups of patients: chronic periodontitis only (No‐DM) or periodontitis and well‐controlled/poorly controlled type 2 diabetes mellitus (WC/PC‐T2DM). Clinical outcomes included probing depth (PD) reduction, bleeding on probing reduction, and clinical attachment level (CAL) gain. Direct and indirect comparisons between groups were assessed by network meta‐analysis, thus allowing us to establish a treatment ranking. Results: Ten prospective cohort studies (11 data sets) were included for qualitative analysis and network meta‐analysis. The data included in this study had high consistency; in addition, a funnel plot and Egger's test showed that the articles had low publication bias. Network meta‐analysis showed that the effect of NSPT in the No‐DM group was significantly better than the WC‐T2DM group [weighted mean difference (WMD) = 0.09, 95% confidence interval (CI) (0.01, 0.18)] and the PC‐T2DM group [WMD = 0.09, 95% CI (0.01, 0.18)] in terms of CAL gain and better than the PC‐T2DM group [WMD = 0.15, 95% CI (0.02, 0.28)] in terms of PD reduction. According to the surface under the cumulative ranking value, the No‐DM group had the highest probability of achieving the best outcome following NSPT. Conclusions: Collectively, our analyses show that T2DM exerts significant effects on the outcomes of NSPT. [ABSTRACT FROM AUTHOR]

Abstract Background Non-surgical periodontal treatment is the mainstay of periodontal treatment. In Malaysia, the prevalence of periodontal disease is substantial among adults with almost half of them having periodontitis. Therefore, we estimated the economic burden of non-surgical periodontal treatment in specialist clinics in Malaysia. Methods Relevant data from multiple data sources which include national oral health and health surveys, national census, extensive systematic literature reviews, as well as discussion with experts, were used to estimate the economic burden of non-surgical periodontal management in specialist clinics in Malaysia in 2020. This estimation was done from the oral healthcare provider’s perspective in both public and private sectors using an irreducible Markov model of 3-month cycle length over a time horizon of one year. Results In 2020, the national economic burden of non-surgical periodontal treatment during the first year of periodontal management in specialist clinics in Malaysia was MYR 696 million (USD 166 million), ranging from MYR 471 million (USD 112 million) to MYR 922 million (USD 220 million). Of these, a total of MYR 485 million (USD 115 million) and MYR 211 million (USD 50 million) were the direct oral healthcare cost in public and private dental clinics, respectively. Conclusion The findings of this study demonstrated substantial economic burden of non-surgical periodontal management in specialist clinics in Malaysia. Being a life-long disease, these findings highlight the importance of enforcing primary and secondary preventive measures. On the strength and reliability of this economic evidence, this study provides vital information to inform policy- and decision-making regarding the future direction of managing periodontitis in Malaysia.

Background/Objectives: Conventional periodontal treatment for patients with diabetes has shown promising results, primarily focusing on glycated hemoglobin (HbA1c) levels as an endpoint measure. The properties of hyaluronic acid (HA) have been harnessed in various periodontal therapies, and it is a promising agent also in a non-surgical approach. The aim of this clinical trial was to assess the efficacy of hyaluronic acid in a local adjunctive non-surgical treatment for periodontitis in patients with type 2 diabetes. Methods: Eighty adult participants with well-controlled type 2 diabetes (HbA1c 7% (53 mmol/mol) or less) took part in the trial. The clinical parameters of periodontitis as well as the glycated hemoglobin (HbA1c) levels were evaluated, and an analysis of the potential differences between the control (placebo) and intervention (HA) groups was performed. Results/Conclusions: A decrease in all the clinical values of periodontitis after treatment was observed in the vast majority of patients in both groups. Differences in the clinical parameters were observed 12 weeks after the intervention between the patients in the placebo and HA therapy groups. Bleeding on probing (BoP) was reduced in the control group to 15–25% and was approximately 5.5% more in the intervention group (9.5–18.25%). The clinical attachment level (CAL) decreased 1 mm more in the HA therapy group (1–2 mm) than in the no adjunctive treatment group (2–3 mm). The probing depth (PD) was reduced similarly in both groups (3–3.75 mm). Due to the bilateral relationship between diabetes and periodontitis, healthcare professionals seek advancements in managing periodontal inflammation. The results of this study indicate that non-surgical periodontal treatment with HA as an adjunctive agent is worth considering in the therapy for patients with diabetes.

Objective: To elucidate the molecular healing of intrabony defects following non‐surgical periodontal therapy (NSPT) using gingival crevicular fluid (GCF). Background Data: Currently limited information is available regarding the GCF of intrabony defects and the change in biomarker levels in the GCF at early time points following treatment interventions. Methods: Twenty‐one patients (Periodontitis Stage III or IV) who have received NSPT, contributing one intrabony defect and one healthy site were included in this study. GCF sampling was performed at baseline, 1 day, 5 days and 3 months after NSPT. Multiplex bead immunoassays allowed the profiling of GCF for 27 markers, associated with inflammation and repair/regeneration. A mixed effects model with Bonferroni correction for multiple comparisons was employed to compare the changes in the levels of GCF markers over time. Results: Following NSPT, changes were observed for several GCF markers, marked by significant increases 1 day post‐intervention, before returning to baseline levels by 3 months. Specifically, GCF concentrations of IL‐2, IL‐4, IL‐6, IL‐8, MMP‐1, MMP‐3, TIMP‐1 and FGFb significantly increased 1 day after NSPT. Signs of activation of cellular senescence were observed 1 day following treatment of intrabony defects, rapidly regressing by 5 days. Conclusion: Significant molecular changes are observed as early as 1 day following NSPT in intrabony defects, along with activation of cellular senescence. [ABSTRACT FROM AUTHOR]

Introduction: This study aims to investigate the level of glycosylated hemoglobin (HbA1c) in non-diabetic subjects with chronic periodontitis and the effect of non-surgical periodontal treatment on HbA1 levels.Materials and methods: In this clinical trial study, 40 non-diabetic subjects 30 to 50 years old were selected in the study in two case and control groups. The case group included 20 non-diabetic subjects with chronic periodontitis and the control group included 20 non-diabetic subjects with healthy periodontium. Clinical periodontal parameters included pocket probing depth (PPD), clinical attachment loss (CAL), gingival index (GI), and glycosylated hemoglobin (HbA1c) was measured in all subjects. The case group received non-surgical periodontal therapy (NSPT). Subjects were re-evaluated for periodontal and HbA1c after three months.Results: Before the non-surgical periodontal treatment, the level of HbA1c in the case group was higher than in the control group (P

Abstract Background Periodontitis is a chronic and multi-factorial infectious disease. A notable difference exists in the prognosis of patients with severe periodontitis after non-surgical periodontal treatment. Thus, a retrospective study was conducted to identify common and specific factors that impact the prognosis of patients with periodontitis stage III-IV following non-surgical periodontal treatment at different tooth sites. Methods A total of 977 teeth were included in the study, comprising 266 patients diagnosed with periodontitis stage III-IV. This sample included 330 anterior teeth, 362 maxillary posterior teeth, and 285 mandibular posterior teeth. Following treatment, the teeth were categorized into two groups based on residual pocket depth [probing depth (PD) ≥ 5 mm] at 3 months post-treatment. The prognosis of periodontitis stage III-IV was assessed through multivariate analysis employing logistic regression to determine the association of various risk factors. Results The PD values of each site and the deepest PD values of each tooth significantly decreased at 3 months post-treatment. Residual pockets were predominantly found in the mesio/disto-buccal and mesio/disto-lingual regions. Multivariate analysis revealed that gender, PD, sulcus bleeding index (SBI) and plaque index (PLI) at baseline, and crown-root ratio in anterior teeth had a significant influence on periodontitis stage III-IV (P

Rheumatoid arthritis (RA) and periodontitis are chronic inflammatory diseases that widely spread and share the same patterns of pro-inflammatory cytokines. This systematic review aims to evaluate the effects of non-surgical periodontal treatment (NSPT) on RA and, conversely, the impact of disease-modifying anti-rheumatic drugs (DMARDs) on periodontitis. PubMed, Embase, and Web of Science were searched using the MESH terms "periodontitis" and "rheumatoid arthritis" from January 2012 to September 2023. A total of 49 articles was included in the final analysis, 10 of which were randomized controlled trials. A total of 31 records concerns the effect of NSPT on parameters of RA disease activity, including a 28-joint disease activity score, anti-citrullinated protein antibodies, rheumatoid factor, C reactive protein, erythrocyte sedimentation rate, pro-inflammatory cytokines and acute phase proteins in serum, saliva, gingival crevicular fluid, and synovial fluid. A total of 18 articles investigated the effect of DMARDs on periodontal indexes and on specific cytokine levels. A quality assessment and risk-of-bias of the studies were also performed. Despite some conflicting results, there is evidence that RA patients and periodontitis patients benefit from NSPT and DMARDs, respectively. The limitations of the studies examined are the small samples and the short follow-up (usually 6 months). Further research is mandatory to evaluate if screening and treatment of periodontitis should be performed systematically in RA patients, and if the administration of DMARDs is useful in reducing the production of cytokines in the periodontium.

Results: The PD values of each site and the deepest PD values of each tooth significantly decreased at 3 months post-treatment. Residual pockets were predominantly found in the mesio/disto-buccal and mesio/disto-lingual regions. Multivariate analysis revealed that gender, PD, sulcus bleeding index (SBI) and plaque index (PLI) at baseline, and crown-root ratio in anterior teeth had a significant influence on periodontitis stage III-IV (P < 0.05). Smoking, PD, PLI and furcation involvement (FI) at baseline, PLI at 3 months post-treatment, grades of periodontitis, and crown-root ratio were prediction factors for maxillary posterior teeth. Factors such as PD, PLI and FI at baseline, PLI at 3 months post-treatment, and crown-root were significant in mandibular posterior teeth. Conclusions: The outcome of non-surgical treatment varies depending on the tooth positions for patients with periodontitis stage III-IV. Dentists must accurately identify the affected teeth that have periodontal pockets of more than 5 mm, taking into consideration the positions of the affected teeth, as well as various local and systemic factors. This comprehensive assessment will enable dentists to develop a customized and effective treatment plan. [ABSTRACT FROM AUTHOR]

Objectives: To (1) investigate dental anxiety (DA) and oral health-related quality of life (OHRQOL) before and after non-surgical periodontal treatment (NSPT) and (2) determine correlations between these patient-reported measures. Materials and methods: Demographics, smoking habits, dental pain, Modified Corah's Dental Anxiety Scale (MDAS), and Oral Health Impact Profile (OHIP-14) were assessed in eighty-two participants. Results: Mean age was 48.3 years ± 11.5. At baseline, 8.5% reported being active smokers. Of non-smokers, 11% reported being an ex-smoker. After NSPT, 11.0% reported smoking. Patients' maximal pain in the last month decreased after therapy. Before treatment, participants reported higher DA. Extreme DA was observed in 8.5% of participants before therapy. Afterwards, 2.4% of participants reported extreme DA. Fear of having a foreign object in the mouth decreased after NSPT. All OHIP-14 scores, except functional limitation, improved post-treatment. Higher DA was associated with worse OHRQoL before treatment. After treatment, total MDAS score was associated with OHIP-14 global score, physical pain, psychological disability, and social disability. Worse MDAS sub-scores were associated with a higher OHIP-14 global score. Individuals with "normal/slight anxiety" had a significant improvement in OHRQoL, whereas people in the "moderate and extreme anxiety" group did not report a significant improvement. Patients diagnosed with generalized periodontitis (GP) stage III grade B and GP stage IV grade B reported less anxiety after NSPT. Conclusions: Associations of MDAS subcategories with OHIP-14 domain scores were found before and after therapy. DA decreases and OHRQoL enhances after NSPT in patients with "normal/slight" anxiety to dental treatment. Dental practitioners should plan strategies to cope with anxiety to dental treatment and prevent decreases in OHRQoL. Clinical relevance: Within the limitations of this study, DA and OHRQoL were positively correlated in patients with periodontitis, before and after NSPT, using the MDAS and OHIP-14 questionnaires. The results of our study suggest that treatment is effective in terms of alleviating DA and improving oral health, along with quality of life, in patients that report "normal/slight" anxiety to dental treatment. Nonetheless, results must be interpreted with caution since patients are generally anxious before any type of dental treatment. DA may not just be confined to NSPT per se. According to our results, evaluation of both outcomes should be an integral part of routine periodontal clinical evaluation and periodontal reevaluation of initial therapy. It is important that clinicians learn to identify patients that suffer from anxiety and take time to explain the treatment procedures to the patient, to strive for patient's emotional well-being before, during, and after dental care services. The use of specific questionnaires for both DA and OHRQoL may be more appropriate to demonstrate the psychological and quality of life differences due to periodontal disease and NSPT.

Objectives: Smokers with periodontitis are therapeutically challenging. Azithromycin (AZM) may be used as an adjunct to periodontal treatment. The aim of this randomized, double-blind, controlled clinical study was to determine the effect of azithromycin in shallow, moderate, and deep pocket depths in smokers when combined with non-surgical periodontal treatment. Material and methods: Forty-nine patients who smoked at least 20 cigarettes per day for more than 5 years were included in the study; however only 40 completed it. The number of teeth, plaque index (PI), gingival index (GI), PPD, CAL, bleeding on probing (BOP) and gingival recession were recorded at baseline and months 1, 3 and 6. The pocket depths (PD) were grouped as shallow, moderate, and deep. Twenty-four patients assigned to the AZM+ (test) group received AZM (500 mg tablets) once a day for 3 days, beginning on the first day of SRP. Results: The decline in the total number of pockets in all groups was statistically significant from baseline to 1 st , baseline to 3 rd , baseline to 6 th ; and from 1 st to 3 rd and 1 st to 6 th months. There was a statistically significant increase in the number of shallow pockets between baseline and 3 rd , baseline and 6 th ; and 1 st and 6 th months (p=0.000) for both groups. Conclusion: Antibiotic administration significantly increased the number of shallow pockets at all time points. However, larger scale controlled clinical studies are needed to verify the efficiency of AZM in smoker periodontitis patients.

Objectives: The aim of this study was to evaluate the clinical efficacy of the adjunctive use of Nd:YAG laser (1064 nm) to full-mouth scaling and root planning (FMS), in stage III/IV periodontitis patients. Materials and methods: Sixty stage III/IV periodontitis patients were randomly assigned to three groups. The control group received FMS, laser 1 group received combined FMS/single Nd:YAG laser irradiation (3 W, 150 mJ, 20 Hz,100 μs), and laser 2 group received combined FMS/double Nd:YAG laser irradiation with 1-week interval (2.0 W, 200 mJ, 10 Hz, 100 μs). PD, CAL, FMPS, GI, FMBS, and GR were evaluated at baseline, 6 weeks, 3, 6, and 12 months after treatment. Patient-reported outcomes were evaluated 1 week after treatment. Results: A significant improvement (p < 0.001) for all clinical parameters was observed during the entire study period, with the exception of mean CAL gain for the laser 2 group at 12 months. The percentage of pockets ≤ 4 mm was significantly higher compared to baseline for all groups throughout the study, with no inter-group differences at any time point. Patient-reported analgesic consumption was higher for laser 1 group. Conclusions: The adjunctive use of Nd:YAG laser irradiation was similarly effective to FMS alone, during the entire study period. A slightly higher, though not statistically significant improvement was reported for PD at 6 and 12 months after a single post-FMS application of Nd:YAG laser for pocket epithelium removal and coagulation. Clinical relevance: Additional Nd:YAG laser application for sulcular epithelium removal and coagulation may provide minor long-term improvements compared to FMS or laser irradiation for pocket disinfection and detoxification.

Objective: To evaluated the relationship between serum vitamin D levels and periodontal healing outcomes in patients with mild or moderate periodontitis. Methods: Serum vitamin D levels and periodontal pockets and gingival bleeding were evaluated in 51 patients before and 6 months after non‐surgical periodontal treatment. A t‐test and chi‐square test were used to analyse the data (p ≤ 0.05). Results: The mean reduction of periodontal pocket depth was statistically significant higher in patients with vitamin D ≥30 ng/ml than those with <30 ng/ml (CI = −0.23–0.42, p = 0.05), but not clinically significant. Vitamin D level was not associated with the percentage of sites of gingival bleeding on probing at the final evaluation (OR = 0.58, 95% CI = 0.17–1.99, p = 0.39). Conclusion: Lower serum vitamin D level was associated with a slightly reduced periodontal healing after non‐surgical periodontal therapy, which should be further investigated in a larger population.

Objectives: Periodontal disease and diabetes have an extensively investigated bidirectional correlation. Non-surgical periodontal treatment (NSPT) was proven to contribute to glycemic control. Moreover, it may benefit from the association of adjunctive therapies. The aim of the present systematic review is to assess the clinical efficacy of NSPT in association with laser (LT) or photodynamic therapy (PDT) in controlled or uncontrolled diabetic patients, and to grade the level of evidence. Materials and methods: Randomized controlled clinical trials with at least 3-month follow-up were searched in MEDLINE via OVID, EMBASE, and Cochrane Central, screened for inclusion, and grouped based on the performed treatments, follow-up time, type of diabetes, and level of glycemic control. Results: Eleven RCTs with 504 total subjects were included. The adjunct of PDT showed a statistically significant 6-month difference in PD changes (with low certainty of evidence), but not in CAL changes, while a significant difference in 3-month PD and CAL changes was found with the adjunct of LT (low certainty of evidence). Patients treated with PDT registered a higher decrease in HbA1c levels at 3 months, but no significant difference was noted at 6 months; LT also led to better HbA1c changes at 3 months with a moderate certainty of evidence. Conclusion: Despite the promising short-term HbA1c decrease, the results should be interpreted with caution due to the small effect sizes and the statistical heterogeneity, and further evidence from well-designed RCTs is needed to support the routine use of PDT or LT in adjunct to NSPT.

Aim: to evaluate the adjunctive effects of photodynamic therapy (aPDT) on nonsurgical mechanical treatment in patients with periodontitis. Materials and methods: The search strategy was conducted according to the PRISMA guidelines to answer research questions regarding the effectiveness of aPDT in association with non-surgical periodontal therapy. The mean values and standard deviations were collected by data extraction. A descriptive comparison between aPDT in association with periodontal treatment and periodontal treatment alone was performed, and meta-analyses of PPD were also performed. Both randomized controlled clinical trials (RCTs) and controlled clinical trials (CCTs) were included. Results: Out of 2059 records, 14 articles on adjunctive photodynamic therapy were included because they met the eligibility criteria. A comparison between the aPDT data and the control group showed improved PPD for photodynamic therapy (SMD −0.76, p = 0.003; I2 = 88%). Statistical analysis was then applied to the three PPD subgroups. The first group included studies that used indocyanine green in association with a wavelength of 810 nm (SMD −1.79, p < 0.00001, I2 = 88%). The second group included studies that used phenothiazine chloride at a wavelength of 660 nm (SMD −0.03, p = 0.84, I2 = 0%). The last group included studies that used methylene blue photosensitizers treated with a wavelength 628–670 nm were included (SMD −0.13, p = 0.38; I2 = 0%). Conclusions: despite the limited number of RCTs and the great heterogeneity between them, it can be concluded that aPDT in association with nonsurgical periodontal treatment improved the clinical parameters at 3 months.

Objective: To study the effectiveness of periodontal dressing on different clinical periodontal parameters after scaling and root planning. Study Design: Randomized Controlled Trial. Setting: Department of Periodontology, Multan Medical & Dental College, Multan. Period: May to July 2020. Material & Methods: Thirty three patients of both genders between ages 30-60 were included. Five clinical parameters were measured at baseline. These variables were recorded by University Of Michigan "O" Probe with William's Markings. The measurements were executed by a single, trained and calibrated examiner. Right and left quadrants of Maxilla and Mandible of the same patient were selected as the test and control sites respectively through random selection by lottery method. The maxillary and mandibular test sides were covered with periodontal dressing for 07 days, later the dressing was detached. After 12 weeks, all clinical parameters were recorded again by the same examiner. Results: Mean age was found to be 45.28 years in males and 41.27 years in females. The mean Kappa value of intra-examiner reliability was identified as 0.95. In comparison to control group, test group showed a highly significant improvement in all five tested periodontal variables when the values were compared at base line and then after 12 weeks. Conclusion: Periodontal dressing has significantly improved the clinical outcomes and the periodontal parameters after Scaling and Root Planning procedures. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the clinical non‐inferiority of a 3‐day protocol of systemic antibiotics adjunctive to subgingival instrumentation (SI) compared with a 7‐day‐protocol in patients with Stage III/IV Grade C periodontitis. Materials and Methods: Fifty systemically healthy patients (32.7 ± 4.3 years) with aggressive periodontitis (AgP; Stage III/IV Grade C periodontitis) were treated by SI and adjunctive amoxicillin and metronidazole and were randomly assigned to Group A: (n = 25) 500 mg antibiotics (AB) 3 times a day for 3 days, followed by placebo 3 times a day for 4 days, or Group B: (n = 25) 500 mg AB 3 times a day for 7 days. Clinical, microbial, and immunological parameters were assessed at baseline, 3 months, and 6 months, and patient‐related outcomes were assessed after 2 weeks. The primary outcome variable was the number of residual sites with pocket depth (PD) ≥6 mm at 6 months. Results: For the primary outcome variable (the number of residual sites with PD ≥6 mm at 6 months), the null hypothesis was rejected and non‐inferiority of the 3‐day AB protocol compared with the 7‐day AB protocol was demonstrated (the upper limits of the 95% confidence interval for intention to treat analysis: [−2.572; 1.050] and per protocol analysis: [−2.523; 1.318] were lower than the assumed margin of Δ = 3.1). Comparable clinical improvements were obtained for all parameters with both antibiotic protocols (p >.05). All investigated periodontopathogens and pro‐inflammatory host‐derived markers were statistically significantly reduced without differences between the treatments (p >.05). Conclusions: These findings indicate that in patients with AgP (Stage III/IV Grade C periodontitis), a 3‐day systemic administration of amoxicillin and metronidazole adjunctive to SI may lead to non‐inferior clinical outcomes after 6‐months with fewer adverse events compared with a 7‐day‐protocol.

Objective: The aim of this study was to determine the levels of resolvin D1 (RVD1) in the gingival crevicular fluid (GCF) and saliva in the patients with periodontitis and healthy subjects, and also to evaluate the effects of non-surgical periodontal treatments (NSPTs) on RVD1 levels. Materials and methods: Fifteen patients with Stage III Grade B periodontitis (P) and 11 periodontally healthy individuals (H) were included in this study. Clinical periodontal measurements, GCF, and saliva samples were collected from each individual at baseline and 6 weeks after NSPTs in periodontitis group. GCF and saliva levels of RVD1 were analyzed by enzyme-linked immunosorbent assay. Results: GCF total and concentration levels of RVD1 were significantly lower in the periodontitis group than in the healthy group and significantly increased after NSPTs in periodontitis (p < 0.001). There was no statistically significant difference in saliva RVD1 levels between healthy and periodontitis group and also before and after NSPTs in periodontitis (p > 0.05). Significant negative correlations were found between all periodontal clinical parameters and GCF volume with both GCF total amount and concentrations of RVD1 (p < 0.01). There was a positive correlation between GCF total amount and concentrations of RVD1 (r = 0.762, p < 0.01). Conclusions: GCF levels of RVD1 might be promising biomarkers for monitoring the susceptibility to periodontitis and predicting periodontal status. Clinical relevance: RVD1 may be valuable biomarker to observe the healing process after periodontal treatment as increased GCF levels might project clinical improvements post-treatment. Accordingly, observing GCF RVD1 levels might be helpful to determine individuals require further periodontal treatment. [ABSTRACT FROM AUTHOR]

Abstract Context The current report is part of a prospective, multi-center, two-arm, quasi-randomized field study focusing on the effectiveness in general praxis of evidence-based procedures in the non-surgical treatment of patients with periodontitis. Objective The specific aims were to (i) evaluate patient-reported experience and outcome measures of treatment following a guided approach to periodontal infection control (GPIC) compared to conventional non-surgical therapy (CNST) and to (ii) identify potential predictors of subjective treatment outcomes and patient’s adherence to self-performed infection control, i.e. adequate oral hygiene. Methods The study sample consisted of 494 patients treated per protocol with questionnaire- and clinical data at baseline and 6-months. The GPIC approach (test) comprised patient education for adequate oral hygiene prior to a single session of full-mouth ultra-sonic instrumentation, while the CNST approach (control) comprised education and instrumentation (scaling and root planing) integrated at required number of consecutive appointments. Clinical examinations and treatment were performed by Dental Hygienists, i.e. not blinded. Data were processed with bivariate statistics for comparison between treatment groups and with multiple regression models to identify potential predictors of subjective and clinical outcomes. The primary clinical outcome was gingival bleeding scores. Results No substantial differences were found between the two treatment approaches regarding patient-reported experiences or outcomes of therapy. Patients’ experiences of definitely being involved in therapy decisions was a significant predictor for a desirable subjective and clinical outcome in terms of; (i) that oral health was considered as much improved after therapy compared to how it was before, (ii) that the treatment definitively had been worth the cost and efforts, and (iii) adherence to self-performed periodontal infection control. In addition, to be a current smoker counteracted patients’ satisfaction with oral health outcome, while gingival bleeding scores at baseline predicted clinical outcome in terms of bleeding scores at 6-months. Conclusions The results suggest that there are no differences with regard to patient-reported experiences and outcomes of therapy following a GPIC approach to periodontal infection control versus CNST. Patients’ experiences of being involved in therapy decisions seem to be an important factor for satisfaction with care and for adherence to self-performed periodontal infection control.

Background. Ferritin is a positive acute phase protein (APP) in inflammation and chronic infections, including chronic periodontitis. Two key factors that can regulate ferritin expression are iron and pro-inflammatory cytokines. Serum ferritin levels increase after menopause, affecting women’s health. This study aimed to evaluate serum ferritin levels in postmenopausal women upon undertaking non-surgical periodontal treatment. Methods. In this cross-sectional study, blood samples of 38 postmenopausal women with chronic periodontitis were collected before any treatment. The serum ferritin levels and periodontal parameters, probing depth (PD), clinical attachment level (CAL), and gingival index (GI) were recorded at baseline and three months after non-surgical periodontal therapy. Wilcoxon test was used to compare serum ferritin levels before and after treatment. T-test was used for comparison of periodontal parameters, with a P value of ≤0.05 considered significant. Results. A decrease was observed in the serum ferritin level (from 108.55 mcg/L to 98.28 mcg/L) after treatment compared to baseline (P

Abstract Background The purpose of periodontal treatments is to reduce inflammation, restore gingival health and clinical attachment level gain by controlling microbial plaque formation and other etiological factors. One of the drugs that has been tested in many areas and shown good anti-inflammatory properties is erythropoietin (EPO). We evaluated the effect of this drug on the improvement of periodontitis after the phase I treatment. Methods This study was conducted on 30 patients with stage III periodontitis who had at least two bilateral teeth with CAL of ≥ 5 mm and PPD ≥ 6 mm at ≥ 2 non‐adjacent teeth and bleeding on probing. After oral hygiene instruction and scaling and root planning (SRP), EPO gel containing a solution of 4000 units was applied deeply in the test group and placebo gel was deeply administered in the control pockets (5 times, every other day). The clinical parameters of the plaque index (PI), gingival index (GI), clinical attachment level (CAL), probing depth (PD) and bleeding index (BI) were measured at baseline and after three months of follow up. The P-value was set at 0.05. Results All clinical variables improved after treatment in both groups. The BI and GI scores (which reflects the degree of gingival inflammation) showed statistically more reduction in test group. The CAL decreased from 5.1 ± 4.1 to 3.40 ± 2.71 mm; and 5.67 ± 4.32 to 4.33 ± 3.19 mm in test and control group, respectively (P

Objectives: To evaluate the clinical and biochemical efficacy of laser therapy as an adjunct to non‐surgical treatment in chronic periodontitis. Methods: A systematic search was performed through the PubMed, EMBASE, and Cochrane Library for eligible articles published as of May 2, 2020, supplemented by information search in the System for Information on Programme Literature in Europe and a manual literature search. Only randomized controlled trials (RCTs) used to compare the adjunctive use of laser and non‐surgical treatment alone with an observation period of at least 6 months were included. Results: Sixteen RCTs with a total of 525 subjects were included. Meta‐analysis suggested that the additional use of laser to scaling and root planing (SRP) showed significant superiority over SRP alone among most of clinical parameters involved. Regarding the GCF, although volume in the laser group was lower at week 4 and 12, no significant difference was found regarding the cytokines level. Subgroup analysis revealed that the combined therapy produced no significant difference in PD, CAL and PI at most time points for studies in respect to smokers. No treatment‐related adverse events had been reported in the included studies. Conclusions: Pooled analysis suggested that laser‐assisted non‐surgical treatment improved clinical outcome to SRP alone in the management of non‐smoking chronic periodontitis patients.

Objective: This study aimed to examine the levels of transforming growth factor‐beta (TGF‐β) and inhibitory‐Smads (I‐Smads) in saliva and gingival crevicular fluid (GCF) in patients with Stage 3 Grade B periodontitis before and after non‐surgical periodontal treatment. Background: Recently, it has been stated that Smads play an active role in all conditions where TGF‐β is involved, including periodontal inflammation. Methods: Twenty healthy participants (control) and 20 patients with Stage 3, Grade B periodontitis were recruited. GCF and saliva samples and clinical periodontal recordings were investigated at the baseline and 1 month after treatment. TGF‐β and I‐Smads (Smads 6 and 7) were determined by ELISA. Results: Salivary Smad6 and Smad7 levels were significantly lower in the periodontitis group than healthy controls (p <.05), while there was no difference in salivary TGF‐β levels between groups at baseline (p >.05). The total amounts and concentrations of GCF TGF‐β, Smad6, and Smad7 were significantly lower in the periodontitis group than healthy controls at baseline (p <.05), and then decreased in concentration levels with treatment (p <.001). Positive correlations were found between total amounts and concentrations of GCF TGF‐β, Smad6, and Smad7 (p <.05). Conclusion: Our findings revealed that Smad6 and Smad7 in GCF and saliva decreased in periodontitis and then increased after periodontal treatment. Our study suggests that I‐Smads act in parallel with TGF‐β in periodontal inflammation and may have a role in the development of periodontitis. [ABSTRACT FROM AUTHOR]

Aim: To analyse the efficacy of non‐surgical therapy (NST) in terms of pocket closure (PC) and changes in percentage and number of pockets. Materials and Methods: Three databases (PubMed, EMBASE, and Scopus) were searched up to January 2020. Prospective studies with a minimum follow‐up of 12 months and presenting data in terms of PC or number or percentage of pocket depths (PDs) before and after NST on systemically healthy patients were included. Random‐effect meta‐analyses were performed. Results: After screening 4610 titles and abstracts, 27 studies were included. Of these, 63.9% of PC was reported by one study. The percentage of PDs ≤3 mm changed from 39.06% to 64.11% with a weighted mean difference (WMD) of 26.14% (p <.001). This accounted for a relative increase of healthy sites of 64.13%. The mean percentage of PD ≥5 mm was 28.23% and 11.71% before and after treatment, respectively, with a WMD of 15.50% (p <.001). The WMD in the number of PDs ≥5 mm before and after treatment was 24.42 (p =.036). The mean number of residual PPD ≥5 after NST was 14.13. Conclusions: NST is able to eradicate the majority of the pockets. However, residual pockets after NST may remain and should be considered cautiously for further treatment planning.

Objectives: To evaluate the cost-effectiveness of the nonsurgical periodontal treatment (NSPT) compared with supragingival therapy in type II diabetics with periodontitis.Methods: A decision tree analysis was used to estimate the costs and health outcomes of two periodontal therapies in a hypothetical cohort of type II diabetics with periodontitis. The analysis was developed from the perspective of a third-party payer at 1 year and 5 years. Probabilities were derived from two systematic reviews. The costs and resource use were validated by a Delphi expert panel. All costs were expressed in USD, using the 25 May 2021 Colombian pesos market exchange rate (USD 1 = COP 3,350).Results: NSPT was a dominant alternative compared with subsidized supragingival therapy in type II diabetics with periodontitis, generating savings of USD 87 and 400, during the first year or up to 5 years, respectively, and improving dental survival from 32 to 69 percent.Conclusions: NSPT can generate savings by reducing the complications derived from uncontrolled periodontitis and tooth loss.

Abstract Background This systematic review aimed to investigate whether non-surgical periodontal therapy (NSPT) can reduce systemic inflammatory levels and improve metabolism in patients undergoing haemodialysis (HD) and/or peritoneal dialysis (PD). Methods Electronic databases (PubMed, EMBASE, CENTRAL, CNKI, and WFPD) were searched for randomized controlled trials (RCTs) performed through July 2019. The risk of bias within studies was assessed with the Cochrane Collaboration’s risk assessment tool. The systemic inflammatory and metabolic outcomes included the highly sensitive C-reactive protein (hs-CRP), interleukin 6 (IL-6), tumour necrosis factor-a (TNF-a), the albumin (Alb), and lipid metabolite levels. Meta-analyses (MAs) were performed to calculate the overall effect size where appropriate. Results Five RCTs were included in this study. Compared with untreated periodontitis groups, the dialysis patients after NSPT significantly showed decreased hs-CRP levels at less than or equal to 2 months (standardized mean difference: − 1.53, 95% confidence interval − 2.95 to − 0.11). No significant difference was found in IL-6 and Alb levels following NSPT at either the 3- or 6- month follow-ups. No MAs could be performed on the TNF-a level and the lipid metabolic markers. Conclusions NSPT can moderately reduce serum hs-CRP levels in HD and/or PD patients, but did not significantly change IL-6 or Alb levels. For TNF-a and lipid metabolism markers, no sufficient evidence supports that these levels are changed after NSPT. Additional scientific research is necessary to assess the effects of NSPT on systemic inflammation and metabolic parameters in dialysis patients.

Aim: to evaluate the adjunctive effects of photodynamic therapy (aPDT) on nonsurgical mechanical treatment in patients with periodontitis. Materials and methods: The search strategy was conducted according to the PRISMA guidelines to answer research questions regarding the effectiveness of aPDT in association with non-surgical periodontal therapy. The mean values and standard deviations were collected by data extraction. A descriptive comparison between aPDT in association with periodontal treatment and periodontal treatment alone was performed, and meta-analyses of PPD were also performed. Both randomized controlled clinical trials (RCTs) and controlled clinical trials (CCTs) were included. Results: Out of 2059 records, 14 articles on adjunctive photodynamic therapy were included because they met the eligibility criteria. A comparison between the aPDT data and the control group showed improved PPD for photodynamic therapy (SMD −0.76, p = 0.003; I2 = 88%). Statistical analysis was then applied to the three PPD subgroups. The first group included studies that used indocyanine green in association with a wavelength of 810 nm (SMD −1.79, p < 0.00001, I2 = 88%). The second group included studies that used phenothiazine chloride at a wavelength of 660 nm (SMD −0.03, p = 0.84, I2 = 0%). The last group included studies that used methylene blue photosensitizers treated with a wavelength 628–670 nm were included (SMD −0.13, p = 0.38; I2 = 0%). Conclusions: despite the limited number of RCTs and the great heterogeneity between them, it can be concluded that aPDT in association with nonsurgical periodontal treatment improved the clinical parameters at 3 months.

Aims: This study aimed to assess the variability and treatment effect heterogeneity in response to non-surgical periodontal therapy (NSPT)., Methods: Data from randomized controlled trials included in two recent systematic reviews on the effect of NSPT on mean clinical attachment loss (CAL), mean probing pocket depth (PPD), percentage of sites with bleeding on probing (%BOP), PPD ≤3 mm (%PD ≤3 mm), and C-reactive protein levels (CRP) at 3-12-month follow-up among adults with systemic diseases or conditions were used. In these trials, the control arms received no treatment, hygiene advice, or supragingival scaling. The Bayesian meta-regression models were utilized to assess the variability ratios between NSPT and control groups., Results: Data from 36 trials on mean PPD, 32 trials on mean CAL, eight trials on %PD ≤3 mm, 31 trials on %BOP and 19 trials on CRP were used. Variability in mean CAL and CRP was approximately 10% higher in the NSPT arms than in the control arms, hinting that there may be room for treatment effect heterogeneity. Instead, variability in mean PPD, %BOP, and %PD ≤3 mm was lower in the NSPT arms than in the control arms., Conclusion: Potential treatment effect heterogeneity in response to NSPT was observed for CRP and mean CAL. However, substantial measurement error in CAL and natural variation in CRP may contribute to these findings. Conversely, treatment effect heterogeneity appears less pronounced for mean PPD, %BOP, and %PD ≤3 mm, potentially due to greater treatment effects in patients with more severe periodontitis and reduced measurement error in these parameters., (© 2024 The Author(s).

Background: Periodontitis is a chronic inflammatory condition that affects the supporting tissues of the teeth, and can lead to serious complications such as tooth loss and systemic health problems, including diabetes, which have a bidirectional relationship with periodontitis. Circulating microparticles originate from different cell types after stimuli such as activation or apoptosis. Interleukins are related to processes in the regulation of the immune response, inflammation, and cell growth. This study aimed to evaluate circulating microparticles as well as interleukins in the plasma, at baseline and 1 month after the end of the non-surgical periodontal treatment., Methods: Samples were collected from 45 patients, with moderate to severe periodontitis with diabetes ( N  = 25) and without diabetes ( N  = 20). Microparticles were evaluated in the platelet-poor plasma by flow cytometer. Cytokine levels were evaluated by the enzyme immunoabsorption assay (ELISA)., Results: Higher levels of the pro-inflammatory cytokines were found in the group with diabetes compared to the non-diabetic group both at baseline and 1 month after the end of the treatment. A higher IL-6/IL-10 ratio was found in patients with diabetes compared to the group without diabetes at T0 and T1, whereas an increased IFN-γ/IL-10 ratio was only found at T1 in patients with diabetes in comparison to the group without diabetes. In the group with diabetes, it was verified positive correlations between IL-10 and IL-6 or IFN-γ and a negative correlation between IL-6 and PMP, at T0; in contrast, in the T1, negative correlations were found between TNF-α and IL-10 or PMP. Besides, at T0, it was evidenced positive correlations both between circulating TNF-α and IL-6, and IL-10 and EMP, as well as a negative correlation between IL-10 and PMP in the group with diabetes. In addition, it was observed in T1 positive correlations between levels of TNF-α and IL-6, IFN-γ, or IL-10, and between PMP and IFN-γ, and between EMP and IL-6, TNF-α and IFN-γ in this group., Conclusion: The results suggest a modulatory effect of the periodontitis associated with diabetes, as well as the periodontal treatment, in the systemic inflammatory status of the participants of the study., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Cassiano, Silveira, Kim, do Amaral, da Silva Nali, Bachi, Resende, Fonseca, de Oliveira Izar, Tuleta, Victor, Pallos and França.)

Background. Ferritin is a positive acute phase protein (APP) in inflammation and chronic infections, including chronic periodontitis. Two key factors that can regulate ferritin expression are iron and pro-inflammatory cytokines. Serum ferritin levels increase after menopause, affecting women's health. This study aimed to evaluate serum ferritin levels in postmenopausal women upon undertaking non-surgical periodontal treatment. Methods. In this cross-sectional study, blood samples of 38 postmenopausal women with chronic periodontitis were collected before any treatment. The serum ferritin levels and periodontal parameters, probing depth (PD), clinical attachment level (CAL), and gingival index (GI) were recorded at baseline and three months after non-surgical periodontal therapy. Wilcoxon test was used to compare serum ferritin levels before and after treatment. T-test was used for comparison of periodontal parameters, with a P value of ≤0.05 considered significant. Results. A decrease was observed in the serum ferritin level (from 108.55 mcg/L to 98.28 mcg/L) after treatment compared to baseline (P<0.001). Also, significant improvements in periodontal parameters were observed compared to the baseline (P<0.001). Conclusion. Based on the results, it can be concluded that non-surgical periodontal treatment significantly reduces serum ferritin levels in postmenopausal women with chronic periodontitis.

Objective: To compare the clinical efficacy and perception of pain between VectorTM -system and a conventional P5 ultrasonic system in the non-surgical treatment of chronic periodontitis. Materials and methods: 45 patients with moderate periodontitis were treated by Vector™-system and a conventional P5 ultrasonic device in a split-mouth design clinical trial. At baseline and 6 weeks after non-surgical phase of treatment was completed, plaque index, bleeding on probing, pocket probing depth and clinical attachment levels were measured and recorded. A visual analogue scale was used to evaluate the patients’ perceived pain immediately after scaling and root planning. Results: At 6 weeks of evaluation, all sites showed an improvement in clinical parameters. No statistically significant differences in pocket probing depth and bleeding on probing was observed between the groups. However the Vector™-system – treated group showed a greater improvement in reduction of pocket depth than P5 device. Patients treated with Vector™-system (mean=22.5 mm, SD=7.53 mm) experienced almost 80% less pain compared with the pain, experienced by the other conventional ultrasonic device (mean=37.16 mm, SD=11.30 mm). Conclusion: During initial periodontal treatment for the patients with moderate periodontitis, Vector™-system could achieve a comparable clinical efficacy in means of reduction of major clinical parameters and reduced pain sensation compared to the conventional ultrasonic device instrumentation.

Background: The purpose of periodontal treatments is to reduce inflammation, restore gingival health and clinical attachment level gain by controlling microbial plaque formation and other etiological factors. One of the drugs that has been tested in many areas and shown good anti-inflammatory properties is erythropoietin (EPO). We evaluated the effect of this drug on the improvement of periodontitis after the phase I treatment. Methods: This study was conducted on 30 patients with stage III periodontitis who had at least two bilateral teeth with CAL of ≥ 5 mm and PPD ≥ 6 mm at ≥ 2 non‐adjacent teeth and bleeding on probing. After oral hygiene instruction and scaling and root planning (SRP), EPO gel containing a solution of 4000 units was applied deeply in the test group and placebo gel was deeply administered in the control pockets (5 times, every other day). The clinical parameters of the plaque index (PI), gingival index (GI), clinical attachment level (CAL), probing depth (PD) and bleeding index (BI) were measured at baseline and after three months of follow up. The P-value was set at 0.05. Results: All clinical variables improved after treatment in both groups. The BI and GI scores (which reflects the degree of gingival inflammation) showed statistically more reduction in test group. The CAL decreased from 5.1 ± 4.1 to 3.40 ± 2.71 mm; and 5.67 ± 4.32 to 4.33 ± 3.19 mm in test and control group, respectively (P < 0.00). After the treatment, there was a significant greater reduction in CAL and also PD values in test group (P < 0.01). Conclusion: Local application of EPO gel in adjunct to SRP can improve clinical inflammation and CAL gain in periodontitis. Trial registration: This study was registered at 2017-11-06 in IRCT. All procedures performed in this study were approved with ID number of IR.TUMS.DENTISTRY.REC.1396.3139 in Tehran University of medical science. [ABSTRACT FROM AUTHOR]

Objective: To evaluate and compare the effects of laser monotherapy with non-surgical mechanical instrumentation alone in untreated periodontitis patients. Materials and methods: A focused question was formulated based on the Population, Intervention, Comparison, Outcome, and Study design criteria (PICOS): in patients with untreated periodontitis, does laser mono-therapy provide adjunctive effects on pocket probing depth (PPD) changes compared with non-surgical instrumentation alone? Both randomized controlled clinical trials (RCTs) and controlled clinical trials (CCTs) were included. The results of the meta-analyses are expressed as weighted mean differences (WMD) and reported according to the PRISMA guidelines. Results: The search yielded 1268 records, out of which 8 articles could be included. With respect to PPD changes, a meta-analysis including 5 articles (n = 148) failed to identify statistically significant differences in favor of laser monotherapy for PPD change (WMD = 0.14 mm; 95% CI: − 0.04/0.32; z = 1.51; p = 0.132) nor for clinical attachment level (CAL) (WMD = 0.04 mm; 95% CI: − 0.35/0.42; z = 0.19; p = 0.850). Data on cost-effectiveness are lacking. One study reported patient-related outcome measures (PROMS). Conclusions: In untreated periodontitis patients, laser monotherapy does not yield superior clinical benefits compared with non-surgical mechanical instrumentation alone. Clinical relevance: In untreated periodontitis patients, mechanical instrumentation with hand and/or ultrasonic instruments remains the standard of care. [ABSTRACT FROM AUTHOR]
