HIỆU QUẢ CỦA AXIT HYALURONIC TRONG HỖ TRỢ ĐIỀU TRỊ VIÊM NHA CHU BẰNG PHƯƠNG PHÁP PHẪU THUẬT

Abstract

Background: Periodontitis is one of the most common oral diseases globally. Surgical treatment of periodontitis combined with hyaluronic acid (AH) has been shown to be clinically effective for deep periodontal pockets. Object: Evaluating the improvement in clinical periodontal indices (Plaque index PlI, Gingival index GI, Periodontal pocket depth PPD, Clinical attachment loss CAL, and Bleeding on probing BOP) and the number of Pg, Td, Fn, Tf bacteria in subgingival plaque after 3 months and 6 months of periodontal treatment by surgical method combined with AH. Materials and method: Randomized, single-blind split-mouth controlled, clinical intervention in patients with periodontitis stages III, IV and levels B or C according to the standards of APP and EFP (2017). The patients were treated non-surgically at the Department of Periodontics before. Results: The group using AH had significantly improved GI, PPD, and CAL indices, and the number of Pg, Td, Fn, and Tf bacteria decreased significantly at 3 months and 6 months after treatment, compared to the control group. Conclusion: Surgical treatment of periodontitis combined with AH is effective in clinical periodontal indices and reduces the number of Pg, Td, Fn, Tf bacteria.
