Objective: The aim of this systematic review and meta-analysis was to evaluate the clinical efficacy of the use of systemic antibiotics in regenerative periodontal surgery for treating teeth affected by periodontitis.
Data sources: Electronic (MEDLINE, EMBASE, LILACS, Scopus, and Cochrane) and manual literature searches for human randomized controlled trial studies published up to November 2022 were conducted by two reviewers. Meta-analysis was performed to assess probing pocket depth (PPD) reduction and clinical attachment level (CAL) gain in groups receiving systemic antibiotics compared to those not receiving systemic antibiotics. A total of eight studies were included. While treated sites were intrabony defects in six papers, two studies focused on furcation defects. For intrabony defects, the weighted mean difference (WMD) of 0.30 mm (95% CI −0.18 to 0.78) and 0.27 mm (95% CI −0.13 to 0.66) was calculated for PPD reduction and CAL gain, respectively. The differences between antibiotics and non-antibiotics groups for PPD and CAL were not statistically significant. Quantitative analysis could not be performed for furcation defects due to the limited number of studies. However, regardless of the membrane type selection, the existing evidence indicated that antibiotics did not lead to superior clinical outcomes for furcation defects at 9 to 12 months after the regenerative procedures.
Conclusion: Based on this meta-analysis study’s findings, the use of adjunct systemic antibiotics in regenerative periodontal surgery did not appear to achieve more favorable clinical outcomes. Thus, the use of adjunct systemic antibiotics as part of the regenerative periodontal therapy might not be justifiable and should be reconsidered.
