Efficacy of Tocopherol vs. Chlorhexidine in the Management of Oral Biopsy Site: A Randomized Clinical Trial

Background/Objectives: Chlorhexidine digluconate (CHX) is widely regarded as the gold standard for oral mucosa antiseptic treatments but has been associated with delayed healing, scar formation, microbiome alterations, and fibroblast toxicity. Tocopherol, with its ability to accelerate tissue healing and minimal side effects, has emerged as a potential alternative. This randomized clinical trial aimed to compare the efficacy of topical tocopherol acetate and 0.2% chlorhexidine in managing postoperative pain and wound healing following oral cavity biopsies. Methods: Seventy-seven patients undergoing oral biopsies were divided into two groups: the test group (tocopherol acetate) and the control group (0.2% chlorhexidine). Pain was assessed using VAS (Visual Analogue Scale) scores on days 1 and 6 postoperatively, and wound healing was evaluated through measurements of the biopsy site’s height and width from standardized photographs analyzed with ImageJ. Painkiller use was also documented....
