Antibiotics as adjunct to non-surgical periodontal therapy in diabetic patients.

data sourcesA comprehensive literature search was performed via MEDLINE/PubMed, Scopus, and Web of Science, including all relevant publications accessed on March 2023 and subsequently updated up to July 2024. Additionally, grey literature was searched, and there was no restriction on publication data and languages. STUDY SELECTION: All randomized clinical trials comparing topical/systemic antibiotics as an adjunct to scaling and root planning (SRP) with SRP alone for the treatment of diabetic patients with periodontitis were included. Literature reviews, case reports and series, preclinical studies or studies lacking periodontal data were excluded. Clinical attachment level was considered as the primary outcome. Bleeding on probing, pocket depth, and gingival index were the secondary outcomes. DATA EXTRACTION AND SYNTHESIS: The risk of bias was evaluated using the Cochrane Collaboration Tool, and for each domain, bias risk was judged as low, unclear and high risk of bias. Selection, removing duplicates, screening, extracting data, and assessing the quality of studies were done by two investigators and findings were tabulated. Meta-analysis was conducted, generating forest plots to compare different treatment modalities, time periods, and antibiotic types. Key periodontal parameters such as probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), and bleeding on probing (BoP) were analysed.

resultsUpon screening and further evaluation of 690 articles, 43 were considered for full-text eligibility. Finally, 30 studies were included in the systematic review, and 27 were included in meta-analysis. Out of 30 randomized clinical trials, 9 studies focused on topical and antibiotics, and 21 involved systemic administration of antibiotics. Five of the nine studies focussing on topical administration of antibiotics, were classified as having a low risk of bias and four as having a high risk of bias. Out of 21 studies on systemic antibiotics, eight were classified as having a low risk of bias, two were undefined, and eleven showed a high risk of bias. Authors concluded that adjunctive use of antibiotics could lead to improvement in periodontal clinical parameters

conclusionThe findings showed that the adjunctive use of antibiotics led to slight improvements in clinical outcomes. However, keeping in mind antibiotic resistance, and side effects of antibiotics, their use should be approached cautiously and only when necessary.
