Evaluation of the Anti-Plaque Effect of a Resveratrol-Based Mouthwash Using a 24-Hour Plaque Re-Growth

Dental plaque is a biofilm that accumulates on tooth surfaces and is a primary factor in the development of gingival inflammation. While toothbrushing remains the main method for plaque control, the effectiveness of mechanical oral hygiene depends largely on individual compliance and technique. As a result, mouthwashes are commonly used as adjunctive chemical plaque control agents. Chlorhexidine gluconate is an effective anti-plaque mouthwash, but its use is associated with undesirable effects that may limit patient acceptance. Resveratrol is a naturally derived compound with reported antimicrobial and anti-biofilm properties, suggesting its potential use as an alternative chemical plaque control agent. This randomized, double-blind, placebo-controlled, three-period crossover clinical trial aims to evaluate the short-term anti-plaque effect of a resveratrol-based mouthwash by measuring supragingival plaque regrowth over a 24-hour period in periodontally healthy individuals. The effects of the resveratrol-based mouthwash will be compared with 0.12% chlorhexidine (CHX) and a placebo mouthwash under standardized conditions without mechanical oral hygiene
