Abstract

Background: After the introduction of antiretroviral therapy (ART), human immunodeficiency virus (HIV) infection has become a chronic controllable disease. For this reason, chronic conditions related to both HIV infection and senescence, such as chronic periodontitis (CP) need to be studied. This study investigated the impact of non-surgical periodontal therapy (NSPT) on clinical and immunological features of CP, and on oral colonization by Candida spp. in HIV-infected and non-HIV-infected individuals.Methods: HIV-infected (test group) and non-HIV-infected (control group) adults patients with CP were selected. Gingival bleeding index (GI), probing depth (PD), clinical attachment level (CAL), number of teeth, CD4+ T lymphocytes and viral load (only for HIV-infected individuals), salivary cytokines (interleukin, [IL]-6, IL-8, and tumoral necrosis factor-alpha [TNF-α]), and oral Candida infection (colony forming units and species) were assessed at baseline, and 30 and 90 days after NSPT.Results: Twenty-two HIV-infected patients and 20 non-HIV-infected patients were evaluated. Candida counts and salivary IL-6, IL-8, and TNF-a levels were higher in the test group than in the control group. Both groups showed a decrease in oral Candida counts, GI, PD, IL-6, and IL-8 as well as gain in CAL at 30 and 90 days after NSPT. In addition, patients in the test group showed an increase of CD4+ T lymphocytes and a decrease of viral load.Conclusion: NSPT had a beneficial impact on clinical and immunological parameters of CP, reduction of oral Candida counts, and improvement of HIV-infection status.

Abstract

Scaling and root planing (SRP) may not always be effective in preventing periodontal disease (PD) progression. The aim of this study was to evaluate the adjunctive effect of antimicrobial photodynamic therapy (aPDT) to SRP on induced PD in rats, analyzing histomorphometrical, immunohistochemical, and immunoenzymatic parameters. Ligatures were placed around the first mandibular molars and second maxillary molars of 60 rats to induce PD. After 14 days, they were removed and the animals were divided into six groups, with nine animals each: G1 = no treatment, G2 = SRP, G3 = light-emitting diode (LED), G4 = SRP + aPDT, G5 = aPDT, and G6 = erythrosine. The animals were euthanized after 3, 7, and 15 days. There were also two control groups (n = 3): without PD (WPD) induction and with maximum PD (PD+). In the histomorphometrical analysis of linear bone loss, G4 showed a statistically significant difference from the other experimental groups after 3 and 15 days. The tartrate-resistant acid phosphatase (TRAP)-positive cell counting was significantly lower in G4 when compared to G2 and PD+ after 3 days. Immunoenzymatic assay shows the values of the ratio (RANKL/OPG × 100). The lowest value is from the WPD group, and the group that received the SRP + aPDT treatment tended to approach this value over time. After 3 days, statistically significant differences were observed between G4 and all other experimental groups, as well as versus PD+ (one-way ANOVA + Tukey's post hoc test were performed, p < 0.05). It was concluded that the adjunctive use of aPDT in combination with SRP showed the best therapeutic results in the treatment of periodontal disease in rats. [ABSTRACT FROM AUTHOR]

Abstract

The purpose of this study was to evaluate the effect of a single application of antimicrobial photodynamic therapy (aPDT) on microbiological profile and cytokine pattern in dogs. Periodontal disease was induced by placing 3.0 silk ligatures around the mandibular pre-molars bilaterally during 8 weeks. The dogs were randomly treated with aPDT using a dye/laser system, scaling and root planning (SRP), or with the association of treatments (SRP + aPDT). Plaque samples were collected at baseline, 1, 3, and 4 weeks, and the mean counts of 40 species were determined using DNA-DNA hybridization. Gingival biopsies were removed and the expression of tumor necrosis factor alpha (TNF-α), receptor activator of NF-kB ligand (RANKL), osteoprotegerin (OPG), matrix metalloproteinase (MMP-1), interleukin (IL) 6, IL-10 and total bacterial load by analysis of 16 S rRNA gene were evaluated through real-time PCR. The results shows that the levels of the majority of the species were reduced 1 week post-therapy for all treatments, however, an increase in counts of Prevotella intermedia (p = 0.00), Prevotella. nigrescens (p = 0.00) and Tannerella forsythia (p = 0.00) was observed for aPDT and SRP + aPDT. After 4 weeks, a regrowth of Porphyromonas gingivalis (p = 0.00) and Treponema denticola (p = 0.00), was observed for all treatments. Also, a strikingly reduction of counts on counts of Aggregatibacter actinomycetemcomitans was observed for the aPDT (p = 0.00). For the cytokine pattern, the results were similar for all treatments, and a reduction in the expression of cytokines and bacterial load was observed throughout the study. Our results suggest that SRP, aPDT in a single application, and SRP + aPDT affects different bacterial species and have similar effects on the expression of cytokines evaluated during the treatment of ligature-induced periodontitis.
