目的:对比Er∶YAG激光与甘氨酸龈下喷砂治疗(subgingival glycine air polishing,GPAP)种植体周炎短期临床效果,为在临床治疗种植体周炎时选择治疗方案提供参考依据.方法:选择自2020年8月～2022年1月期间发生种植体周炎的38例患者为研究对象.使用随机数表法将其分为Er∶YAG激光组(A组)和GPAP组(B组),由不知分组情况的相同医生行超声刮治,之后A组采用Er∶YAG激光治疗,B组使用GPAP治疗,记录并评估治疗前以及治疗后6个月时的平均探诊深度(mean probing depth,MPD)、探诊出血指数(bleeding on pro-bing,BOP)、临床附着丧失(clinical attachment lost,CAL)这 3 项临床指标.采用 IBM SPSS Statistic 25.0 对数据进行统计学分析.结果:A、B两组在术后6个月的MPD、BOP指数较基线水平均明显降低(P＜0.05),A组较B 组效果更佳[(1.98±0.34)mm vs.(2.43±0.51)mm;0.68±0.75 vs.1.21±0.71;P＜0.05],A 组经治疗后CAL 指标显著降低[(2.10±0.39)mm vs.(1.21±0.27)mm;P＜0.001],B 组经治疗后 CAL 无明显改善(P＞0.05).结论:Er∶YAG激光治疗相较于GPAP治疗种植体周围软组织炎症效果更为显著,经Er∶YAG激光治疗的患者在6个月的观察时间内恢复了部分丧失的骨组织.
Randomized Controlled Study on Short-term Clinical Effects of Er∶YAG Laser Versus Subgingival Glycine Air Polishing in Treatment of Peri-implantitis
Objective:To compare the short-term clinical effects of Er∶YAG laser and subgingival glycine air polis-hing(GPAP)in the treatment of peri-implantitis.Methods:A total of 38 patients with peri-implantitis from August 2020 to January 2022 were selected as the study subjects.They were divided into Er∶YAG laser group(Group A)and GPAP group(Group B)by random number table method.Ultrasound subgingival scaling was performed by the same doctor who did not know the grouping condition.Then,Group A was treated with Er∶YAG laser,and Group B was treated with GPAP.The mean probing depth(MPD),bleeding on probing(BOP),and clinical attachment loss(CAL)were examined.Results:In contrast to baseline level,the MPD and BOP indexes in Group A and Group B were significantly lowered 6 months after operation(P＜0.05),and the effect of Group A was better than that of Group B[(1.98±0.34)mm vs.(2.43±0.51)mm;0.68± 0.75 vs.1.21±0.71;P＜0.05].The CAL index was sig-nificantly reduced in Group A after treatment[(2.10± 0.39)mm vs.(1.21±0.27)mm;P＜0.001],however,no significant improvement in Group B after treatment(P＞0.05).Conclusion:Er∶YAG laser treatment was more effective than GPAP in treating peri-implant soft tissue in-flammation,and patients treated with Er∶YAG laser recovered the lost bone tissue to some extent within an obser-vation period of 6 months.
