摘要： 目的 评价65 μm甘氨酸颗粒用于龈上洁治抛光的临床疗效。方法 选取33例牙龈炎病例,行常规龈上超声洁治后,按抛光方式不同,采用裂口对照随机将左右侧分为试验组或对照组。实验组用甘氨酸颗粒抛光,对照组用碳酸氢钠颗粒喷砂+抛光膏抛光。记录在基线、1周、1个月、3个月、6个月时的探诊深度（PD）、菌斑指数（PI）、出血指数（BI）及色素指数（SI）。采用SPSS 23.0软件包对实验结果进行配对样本Wilcoxon 符号秩和检验。结果 实验组相对于对照组在不同时期PD、PI、BI差异均无统计学意义,但在1个月、3个月、6个月复查时,实验组SI显著低于对照组（P<0.01）。2组在1个月、3个月、6个月时的PD、PI、BI、SI均较该组基线时相应指标显著改善（P<0.01）。结论 65 μm甘氨酸颗粒相比传统的碳酸氢钠颗粒可以减弱色素的再附着,值得临床推广应用。

Abstract: PURPOSE: To evaluate the clinical effect of 65 μm glycine powder air-polishing (GPAP) by comparing with sodium hydrogen carbonate after ultrasonic scaling during subgingival polishing. METHODS: Thirty-three patients who were systematically healthy were involved in this study. After ultrasonic scaling,they were randomly assigned to the experimental group or the control group. Patients in the control group were treated with rubber cup + sodium hydrogen carbonate, while patients in the experimental group were treated only with 65 μm GPAP therapy. The clinical parameters including probing depth(PD), bleeding index(BI), plaque index(PI), staining index(SI) were recorded at baseline, 1week, 1 month, 3 months and 6 months after treatment. The results were analyzed by paired sample Wilcoxon signed-rank test with SPSS 23.0 software package. RESULTS: Both methods had good clinical effects. PD, BI, PI and SI of the two groups at 1 month, 3 months and 6 months after treatment were significantly better than those at baseline (P<0.01). SI of the experimental groups was significantly lower than that of the control group at 1 month, 3 months and 6 months after treatment(P<0.01). CONCLUSIONS: The results indicated that 65 μm GPAP may be as effective as sodium hydrogen carbonate after ultrasonic scaling in removal of dental plaque and stain. 65 μm GPAP had the advantage of reducing restaining.
