上皮下结缔组织瓣移植术对牙周炎附着龈过窄患者附着龈宽度及牙周指标的影响

Effect of Subepiepithelial Connective Tissue Flap Grafting on Adhesive Gingival Width and Periodontal Indexes in Periodontitis with Adhesive Gingival Hypernarrow Patients

目的:探究上皮下结缔组织瓣移植术对牙周炎附着龈过窄患者附着龈宽度及牙周指标的影响。方法:选取瑞金市人民医院口腔科在2021年6月—2023年2月收治的101例牙周炎附着龈过窄患者作为研究对象,按随机数字表法分为观察组(51例)和对照组(50例)。对照组行根向复位瓣术,观察组行上皮下结缔组织瓣移植术。观察两组疗效、附着龈宽度、牙周指标及并发症情况。结果:观察组总有效率(96.08%)高于对照组(82.00%),差异有统计学意义(P<0.05)。术后3个月,观察组的附着龈宽度大于对照组(P<0.05);与术前相比,术后3个月两组出血指数(bleeding index,BI)、菌斑指数(plaque index,PI)、探诊深度(probing depth,PD)均降低,观察组均低于对照组(P<0.05)。观察组并发症发生率为1.96%,对照组为6.00%,差异无统计学意义(P>0.05)。结论:上皮下结缔组织瓣移植术对牙周炎附着龈过窄患者有良好的疗效,可有效增加附着龈宽度,改善牙周指标。

Objective:To investigate the effects of subepithelial connective tissue flap grafting on the adhesive gingival width and periodontal indexes in periodontitis with adhesive gingival hypernarrow patients.Method:A total of 101 patients with periodontitis with adhesive gingival hypernarrow admitted to the Stomatology Department of Ruijin People's Hospital from June 2021 to February 2023 were selected as the study objects,and they were divided into observation group(51 cases)and control group(50 cases)by random number table method.The control group underwent root-oriented reduction flap,and the observation group underwent subepithelial connective tissue flap grafting.The efficacy,adhesive gingival width,periodontal indexes and complications of the two groups were observed.Result:The total effective rate of observation group(96.08%)was higher than that of control group(82.00%),the difference was statistically significant(P<0.05).The adhesive gingival width in the observation group was greater than that in the control group at 3 months after operation(P<0.05).Compared with preoperation,bleeding index(BI),plaque index(PI)and probing depth(PD)of the two groups were decreased 3 months after operation,and those in the observation group were lower than those in the control group(P<0.05).The incidence of complications was 1.96% in the observation group and 6.00%in the control group,the difference was not statistically significant(P>0.05).Conclusion:Subepithelial connective tissue flap grafting has a good effect on periodontitis patients with adhesive gingival hypernarrowness,which can effectively increase the adhesive gingival width and improve periodontal indexes.
