Background: Supplementation with omega-3 polyunsaturated fatty acids (-3 PUFA) and low-dose aspirin (ASA) have been proposed as a host modulation regimen to control chronic inflammatory diseases. The aim of this study was to investigate the clinical and immunological impact of orally administered-3 PUFA and ASA as adjuncts to periodontal debridement for the treatment of periodontitis in patients type 2 diabetes. Methods: Seventy-five patients (n = 25/group) were randomly assigned to receive placebo and periodontal debridement (CG),-3 PUFA + ASA (3 g of fish oil/d + 100 mg ASA/d for 2 months) after periodontal debridement (test group [TG]1), or-3 PUFA + ASA (3 g of fish oil/d + 100 mg ASA/d for 2 months) before periodontal debridement (TG2). Periodontal parameters and GCF were collected at baseline (t0), 3 months after periodontal debridement and-3 PUFA + ASA or placebo for TG1 and CG (t1), after-3 PUFA + ASA (before periodontal debridement) for TG2 (t1), and 6 months after periodontal debridement (all groups) (t2). GCF was analyzed for cytokine levels by multiplex ELISA. Results: Ten patients (40%) in TG1 and nine patients (36%) in TG2 achieved the clinical endpoint for treatment (less than or equal to four sites with probing depth ≥ 5 mm), as opposed to four (16%) in CG. There was clinical attachment gain in moderate and deep pockets for TG1. IFN-and interleukin (IL)-8 levels decreased over time for both test groups. IL-6 levels were lower for TG1. HbA1c levels reduced for TG1. Conclusion: Adjunctive-3 and ASA after periodontal debridement provides clinical and immunological benefits to the treatment of periodontitis in patients with type 2 diabetes.

Within the limitations of this study, results indicate that LLLT showed no additional benefit in the long term when associated with a CTG in the treatment of Miller Class I and II GRs.

Results from this study suggest both treatments are effective; however, adjunct use of CLM to FMUD leads to better reduction of deep pockets and Pg at 6 months compared with FMUD alone.

Only the SNP rs6667202 was associated with AgP in a Brazilian population, being the minor C allele protective against AgP. Moreover, SNPs rs1333048 and rs1537415, previously associated with AgP in other population, was not validated to Brazilian population.

Diabetes has become a global epidemic. Its complications can have a significant impact on quality of life, longevity, and public health costs. The presence of diabetes might impair the prognosis of periodontal treatments due to its negative influence on wound healing. Antimicrobial photodynamic therapy (aPDT) is a local approach that can promote bacterial decontamination in periodontal pockets. The aim of this study was to investigate the local effect of adjunct aPDT to ultrasonic periodontal debridement (UPD) and compare it to UD only for the treatment of chronic periodontitis in type 2 diabetic patients. Twenty type 2 diabetic patients with moderate to severe generalized chronic periodontitis were selected. Two periodontal pockets with probing depth (PD) and clinical attachment level (CAL) ≥5 mm received UPD only (UPD group) or UPD plus adjunct aPDT (UPD + aPDT group). Periodontal clinical measures were collected and compared at baseline and 30, 90, and 180 days. After 180 days of follow-up, there were statistically significant reductions in PD from 5.75 ± 0.91 to 3.47 ± 0.97 mm in the UPD group and from 6.15 ± 1.27 to 3.71 ± 1.63 mm in the UPD + aPDT group. However, intergroup analysis did not reveal statistically significant differences in any of the evaluated clinical parameters (p > 0.05). The adjunct application of aPDT to UPD did not present additional benefits for the treatment of chronic periodontitis in type 2 diabetic patients. The ClinicalTrials.gov identifier of the present study is NCT02627534.

Background:The aim of this study was to evaluate the clinical, radiographic and patient-centered results of enamel matrix derivative (EMD) therapy in intrabony defects in aggressive periodontitis (AgP) patients and compare them with those in chronic periodontitis (CP) patients.Methods: Sixty intrabony defects in AgP and CP patients associated with ≥ 6 mm residual probing pocket depth (PPD) were included and randomly assigned to one of three groups: AgP+CS (conservative surgery) (n = 20); AgP+CS/EMD (n = 20); CP+CS/EMD (n = 20). Clinical parameters were measured at baseline and after 6 and 12 months. Defect resolution (DR) and bone filling (BF) were used for radiographic analysis. The quality of life was recorded at baseline and 6 months using OHIP-14 and VAS scale in the early post-therapy period.Results: PPD and relative clinical attachment level (rCAL) improved for all groups during follow-up (P ≤ 0.05), and AgP+CS/EMD presented a higher rCAL gain (2.4 ± 1.0 mm) when compared to AgP control patients (1.6 ± 1.6 mm, P ≤ 0.05) after 12 months. No difference was observed between AgP+CS/EMD and CP+CS/EMD groups (P > 0.05). No radiographic differences were observed among groups at any time point (P > 0.05). All the groups reported a positive impact on OHIP-14 total score, without differences among them.Conclusions: EMD therapy of intrabony defects promotes additional benefits in AgP patients, presenting a similar regeneration rate compared to CP patients, and has proven to be a viable therapy for the treatment of individuals with AgP.

Background To assess the clinical and microbiological responses of amoxicillin + metronidazole (AMX + MET) versus clarithromycin (CLM) as adjuncts to one‐stage full‐mouth ultrasonic debridement (FMUD) in the treatment of generalized aggressive periodontitis (GAgP). Methods For this parallel, double‐masked, pilot randomized clinical trial, 46 patients with GAgP were selected and randomly assigned into two groups: AMX+MET group (n = 23): FMUD associated with AMX (500 mg three times a day) and MET (400 mg three times a day) for 7 days; and CLM group (n = 23): FMUD associated with CLM (500 mg twice a day) for 7 days. Clinical parameters were evaluated at baseline, 3, and 6 months post‐treatment. The levels of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, and Fusobacterium nucleatum from subgingival biofilm were determined by quantitative polymerase chain reaction. Results Both treatments significantly improved all clinical parameters compared with baseline and promoted a significant reduction of A. actinomycetemcomitans and P. gingivalis counts (P > 0.05). CLM succeeded in decreasing T. forsythia at 6 months (P < 0.05), but no antibiotic was able to reduce F. nucleatum. There was no difference between the two protocols regarding the reported adverse effects (P > 0.05). Conclusions The results suggest that CLM is not superior than AMX + MET in the treatment of GAgP. However, this antibiotic led to good clinical outcomes and may be a possible alternative to AMX+MET in the treatment of severe periodontitis in young patients. Future studies with larger sample sizes are needed to confirm this statement (NCT02969928).
