Background: Periodontitis is a prevalent inflammatory condition that destroys periodontal tissues. Scaling and root planing (SRP) is the gold standard for non-surgical treatment; however, its efficacy may be limited in cases with complex dental issues. This umbrella review aims to evaluate the effectiveness of hyaluronic acid (HA) as an adjunct to scaling and root planing (SRP) in enhancing clinical outcomes for periodontitis management. Methods: A comprehensive review of five systematic reviews, including meta-analyses where available, was conducted to synthesize evidence on the adjunctive use of HA with SRP. The studies were evaluated using the AMSTAR-2 quality assessment tool to determine methodological rigor. Data on clinical parameters such as probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), gingival index (GI), and plaque index (PI) were extracted and analyzed. Results: The findings indicate that HA supplementation leads to moderate improvements in PD, CAL, BOP, GI, and PI compared to SRP alone. Notable reductions in PD and gains in CAL were observed, with some meta-analyses showing statistically significant benefits. However, the heterogeneity in HA concentrations (0.2–1.4%), application methods, treatment frequencies, and follow-up durations (1 week to 12 months) limits definitive conclusions. Additionally, HA did not significantly affect the reduction in P. gingivalis prevalence. Conclusions: The use of HA in conjunction with SRP shows promise in enhancing the efficacy of non-surgical periodontal therapy. However, the heterogeneity in the quality and methodologies of the studies indicates the necessity for high-quality, standardized randomized controlled trials to establish clear clinical guidelines for the application of HA in the treatment of periodontitis.
