Background: The aim of this systematic review (SR) was to evaluate the clinical efficacy of different adjunctive methods/therapies to the non-surgical treatment (NST) of peri-implantitis., Materials and Methods: The protocol of the review was registered in PROSPERO database (CRD42022339709) and was designed according to PRISMA statement. Electronic and hand searches were performed to identify randomized clinical trials (RCTs) comparing non-surgical treatment of peri-implantitis alone versus NST plus any adjunctive method/treatment. The primary outcome was probing pocket depth (PPD) reduction., Results: Sixteen RCTs were included. Only 2 out of 1189 implants were lost and follow-up ranged from 3 to 12 months. PPD reduction across the studies varied from 0.17 to 3.1 mm, while defect resolution from 5.3% to 57.1%. Systemic antimicrobials were associated to higher PPD reduction (1.56 mm; [95% CI 0.24 to 2.89]; p = 0.02) with high heterogeneity, and treatment success (OR = 3.23; [95% CI 1.17 to 8.94]; p = 0.02), compared to NST alone. No differences were found with adjunctive local antimicrobials and lasers for PPD and bleeding on probing (BoP) reduction., Conclusions: Non-surgical treatment with or without adjunctive methods may reduce PPD and BoP even if complete resolution of the pocket is unpredictable. Among possible adjunctive methods, only systemic antibiotics seems to provide further benefits, but their usage should be considered with caution., (© 2023. The Author(s).)

Aim: To evaluate outcome measures, methods of assessment, and analysis in clinical studies on fixed single- and multiple-unit implant restorations., Materials and Methods: Three independent electronic database searches (MEDLINE, EMBASE, and Cochrane) were done to identify prospective and retrospective clinical studies published from January 2011 up to June 2021 with ≥20 patients and minimum 1-year follow-up period on technical and clinical outcomes of implant-supported single crowns (SCs) and partial fixed dental prostheses (P-FDPs). An entire data extraction was performed to identify primarily the most reported outcome measures and later to define the choice of assessment methods of those outcome measures. The outcomes were analysed descriptively, and the strength of association was evaluated using the Pearson chi-square test (p ≤ .05)., Results: In a total 531 studies, 368 on SCs (69.3%), 70 on P-FDPs (13.1%), and 93 on both restoration types (17.5%) were included; 56.3% of all studies did not clearly define a primary outcome. The most frequent primary outcome was marginal bone level (MBL) (55.2%) followed by implant survival (5.3%), professional aesthetic evaluation (3.4%), and technical complications (2.1%). Peri-implant indices were the most reported secondary outcome (55.1%), followed by implant survival (39.9%), MBL (36%), and implant success (26.4%). Prosthetic failure (seven studies [3.9%]) was one of the least reported outcome measures., Conclusions: Outcome measures and their assessment methods showed high heterogeneity among studies. Primary outcomes were not often defined clearly, and the most frequently selected primary outcome was marginal bone loss. Prosthetic outcomes, implant survival, and patient-related outcomes were only infrequently reported., (© 2022 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objectives: Aims of this SR were to assess the association of Periodontitis (PD) with Chronic Kidney Disease (CKD) and with different CKD stages., Materials and Methods: MEDLINE, Cochrane Central Register of Trials and EMBASE, up to April 4, 2021 were searched. RCTs, prospective and retrospective cohort studies, case-control studies and cross-sectional studies were considered. JBI's Critical Appraisal Tool for risk of bias assessment was used. The risk of PD was calculated using the Mantel-Haenszel odds ratios (MH-OR); weighted mean difference for clinical attachment level (CAL) and periodontal probing depth (PPD) were also evaluated., Results: Out of 1949 titles screened, 142 full texts were evaluated and 17 studies were included. CKD was associated to higher risk of PD (MH-OR = 2.36, [95% C.I. 1.25, 4.44]; p = 0.008), higher mean CAL (WMD = 0.41 mm [95% C.I. 0.22, 0.60]; p < 0.0001) and mean PPD (WMD = 0.25 mm [95% C.I. 0.03, 0.47]; p = 0.02) compared to healthy individuals. Severe CKD (stages 4-5 vs 2-3) resulted at higher risk of PD (MH-OR = 2.21, [95% C.I. 1.07, 4.54]; p = 0.03). Heterogeneity and risk of bias were high., Conclusions: An association between PD and CKD was found. It could be appropriate to consider PD a frequent CKD comorbidity., (© 2021 Wiley Periodicals LLC.)

Herpes Simplex Virus type 1 (HSV-1) is a very common infection often localized in the mucocutaneous junction of the lip. Rarely, it could be detected also in periodontal tissues, associated with an elevated risk of periodontal disease progression and gingival recessions. Recently, HSV-1 and numerous co-infections have been reported in literature associated with the Coronavirus and subsequent COVID-19 disease. This report illustrates a case of HSV-1 in a patient with Covid-19 infection, showing the presence of ulcers and vesicles on the gingival margin of maxillary teeth associated with soreness and pain. The histology highlighted the presence of intraepithelial cell ballooning, confirming the diagnosis of HSV-1 infection., Competing Interests: The authors have stated explicitly that there are no conflicts of interest in connection with this article., (© 2022 The Authors.

Objective: The aim of the present study was to assess the extent and severity of periodontal disease among type 1 diabetic patients (T1DM) and to investigate the possible association with systemic markers of glucose control and variability., Material and Methods: Patients were consecutively enrolled in a Diabetic Unit. A full-mouth periodontal evaluation was performed, and data on systemic markers of diabetes were collected. Descriptive statistics and logistic and linear models were performed., Results: A total of 136 T1DM patients (mean age: 45.5 ± 14.6 years) were examined. Periodontitis was detected in 62% of cases (mean CAL: 3.0 ± 0.9 mm): stage III periodontitis was diagnosed in 32% of patients while stage IV in 8%. Mean level of glycated hemoglobin (HbA1c) was 7.5% ± 1.4. Among the investigated factors, mean CAL (p=0.040) was associated with HbA1c ≥ 7%; 93% of patients with mean CAL > 6 mm showed HbA1c ≥ 7%. Mean CAL (p=0.004), mean PPD (p=0.005), mean FMPS (p=0.030), and stage III/IV periodontitis (p=0.018) predict glucose coefficient of variation (CV)., Conclusions: Periodontitis showed a relevant prevalence in the present, well-controlled T1DM population and predicts poor glycemic control (HbA1c ≥7%) and higher glucose variability. The present findings suggest that periodontal infection may have systemic effects also in T1DM patients., Clinical Relevance: The extent and severity of periodontitis and its possible systemic effects in T1DM patients could be underestimated., (© 2021.

Aims: Periodontal disease (PD) is a chronic inflammation of periodontal tissue associated with infection from specific anaerobic pathogens contained in dental plaque. Both type 1 and type 2 diabetes are associated with an increased prevalence of PDs. A two-way relationship between diabetes and periodontitis has been proposed, with diabetes increasing the risk for periodontitis, and periodontal inflammation negatively affecting glycaemic control. To date, the relationship between PD and glucose variability in type 1 diabetes has not been evaluated. To investigate the prevalence of PD in patients with type 1 diabetes and its association with glycemic control and glucose variability., Methods: In this cross-sectional study, all enrolled patients were scheduled to attend both a diabetologic and a periodontal visit. HbA1c, glucose coefficient of variation (CV), loss of clinical attachment (CAL), and periodontal probing depth (PPD) were collected., Results: 136 patients were included in the analysis. The prevalence of PD was 63%. A significant correlation was found between mean CAL and glucose CV (r = 0.31, p = 0.002), but not with HbA1c. Mean PPD was also associated with glucose CV (r = 0.27 and 0.044), but not with HbA1c. In a multiple linear regression model, with mean CAL as dependent variable, age, glucose CV, and smoking habit resulted significantly associated (r = 0.23, p = 0.013; r = 0.33, p = 0.001; r = 0.34, p < 0.001, respectively). Assuming mean PPD as dependent variable, multiple linear regression analysis showed a significant association with glucose CV and smoking habits only., Conclusions: PD is associated with glucose variability in patients with type 1 diabetes also after adjusting for the main confounders., (© 2021.

Aims: Data about the association between periodontal disease or periodontitis (PD), diabetes and hyperglycemia have been reported mostly in patients with type 2 diabetes. Conversely, information about PD in type 1 diabetes (T1DM) is relatively scarce. The aim of this meta-analysis is therefore: (1) to assess the prevalence and severity of PD in patients affected by T1DM in comparison with the general population and (2) to verify the association between severity of PD and glycemic control in type 1 diabetics., Methods: An electronic search was performed on MEDLINE, Cochrane Central Register of Trials and EMBASE, up to October 31, 2019. Estimates of prevalence of PD in T1DM were calculated together with Mantel-Haenszel odds ratios (MH-OR) of the risk of PD associated with T1DM; weighed mean difference in CAL between T1DM and control and weighed mean difference in CAL in patients with T1DM and unsatisfactory glycemic control as compared with those in good glycemic control were also evaluated.., Results: The prevalence of PD in type 1 diabetes was 18.5 [8.0; 37.1] %; the MH-OR for PD is 2.51 (1.32;4.76) in T1DM patients versus general population (p = 0.005). The weighed mean difference in CAL depth between T1DM patients and controls is 0.506 [0.181; 0.832] mm (p < 0.005), and in T1DM patients with good glycemic control CAL depth is - 0.71 [- 1.00; - 0.42] mm less deep than in subjects with HbA1c > 7%., Conclusions: The present data confirm that T1DM is a relevant risk factor for the development of PD. The proportion of patients affected by PD is more than doubled in subjects with T1DM in comparison with non-diabetic individual, and among patients with T1DM, PD seems to be more severe and the differences appear very wide between subjects in optimal and suboptimal glycemic control.
