目的：：观察透明质酸治疗慢性牙周炎的临床疗效。方法：将40名慢性牙周炎患者随机分为实验组和对照组(n=20)。所有患者进行龈上洁治、龈下刮治及根面平整术后，实验组牙周袋内给予透明质酸，对照组牙周袋内给予碘甘油。记录并分析基线及刮治后4、8周时牙龈指数( GI)、牙周探诊深度( PD)、出血指数(BI)、附着丧失水平(CAL)。结果：治疗后两组各项牙周指标与基线相比均有显著性差异(P<0.05)；治疗后4、8周时，实验组各牙周指标略优于对照组，差异无统计学意义(P>0.05)。结论：未发现透明质酸在慢性牙周炎的治疗中具有比碘甘油更显著的作用。

AIM:To investigate the clinical effects of hyaluronic acid in the treatment of chronic periodonti-tis. METHODS:40 patients with chronic periodontitis were divided into 2 groups(n=20). All patients were treated by scaling and root planning. Hyaluronic acid was administered in the periodontal pocket in the experimental group and iodine glycerin in the control group. Gingival index ( GI ) , probing depth ( PD) , beeding index ( BI) and clinical at-tachment level (CAL) were evaluated before treatment and 4, 8 weeks after treatment. RESULTS:In both groups, a significant improvement of the indicators was found after therapy (P<0. 05). And comparison between experimental and control groups showed no statistically significant differences in the indicators 4 and 8 weeks after treatment (P>0. 05). CONCLUSION:Hyaluronic acid is not more effective than iodine in the treatment of periodontitis.
