Objectives: This study aimed to assess the effects of omega-3 fatty acid supplementation as an adjunct to non-surgical periodontal therapy in patients with periodontitis.
Materials And Methods: This randomized clinical trial was conducted on 30 patients with periodontitis. All patients received standard non-surgical periodontal therapy, and were randomly divided into two groups of intervention and control by a table of random numbers (n = 15). The intervention group consumed 1000 mg natural fish oil soft-gels daily (300 mg Omega-3 marine triglycerides, 180 mg Eicosapentaenoic acid and 120 mg Docosahexaenoic acid) while the control group used soft-gels contained only some soybean oil for 3 months. Clinical attachment loss (CAL), probing depth (PD), and bleeding index (BI) were recorded at baseline (before the intervention) and after 3 months. The two groups were compared regarding the clinical parameters by t-test (alpha = 0.05).
Results: All three clinical parameters decreased in both groups at 3 months compared with baseline (P = 0.001). The improvement in PD and CAL in the intervention group was significantly greater than that in the control group (P = 0.001); however, the difference in BI was not significant between the two groups (P = 0.283).
Conclusion: Omega-3 supplementation as an adjunct to non-surgical periodontal therapy significantly improved the clinical parameters in periodontitis patients compared to soybean oil supplements.

Aim: Tissue-invasive bacteria have been proposed to be a crucial factor in the etiopathogenesis of periodontitis, with the probable interaction of tissue-invasive bacteria with the innate immune response through inflammasomes, perpetuating periodontal attachment loss. This study aims to reveal the correlation between such tissue-invasive bacteria in upregulating inflammasomes and pro-inflammatory cytokines.
Materials And Methods: This study recruited a total of 10 patients with stage III/IV and grade C periodontitis based on the bone loss to age ratio.

: The aim of the present narrative review is to synthesize the available scientific evidence on the effects of submarginal instrumentation with periodontal endoscopy and evaluate its' potential efficacy in terms of the non-surgical therapy of peri-implantitis. : The literature search was performed via electronic databases, including PubMed, Web of Science, Cochrane, and Scopus, and was supplemented by manual searching. A literature review was conducted addressing the following PICOS questions: (1) What is the efficacy of non-surgical submarginal instrumentation of the implant surface with the aid of a periodontal endoscope in patients with peri-implantitis? (2) What is the efficacy of non-surgical subgingival instrumentation performed with the aid of a periodontal endoscope compared with conventional subgingival instrumentation in patients with periodontitis, in terms of clinical parameters and patient-reported outcomes? Mechanical decontamination of the implant surface is crucial for resolving inflammation and arresting further bone loss.

: Periodontal inflammation, often linked to oral microbiota dysbiosis dominated by pathogenic bacteria, remains a significant challenge in periodontitis management. Traditional periodontal therapies primarily reduce the bacterial load but fail to restore the microbiota balance. Probiotics offer a promising therapeutic adjunct with their ability to enhance beneficial bacteria.

Background/objectives: The gold standard in the non-surgical treatment of periodontitis is scaling and root planning (SRP). In recent years, studies have emerged suggesting additional clinical benefits from the use of statins as an adjunct to classical periodontal disease treatment. The aim of the present study was to review the relevant literature relating to the subgingival use of statins as an adjunctive treatment to the classical, non-surgical treatment of periodontitis, with a particular focus on groups with general factors that may affect the outcome of treatment.

Objectives: To investigate if photobiomodulation (PBM) can reduce dentin hypersensitivity (DH) through a randomized, controlled, double-blind clinical trial.
Materials And Methods: One hundred and twelve patients experiencing DH after non-surgical scaling and root planing (SRP) were enrolled and divided into the Experimental Group - SRP + PBM (660 nm, 1.061 J/cm²) and the Control Group - SRP + PBM simulation.
