摘要： 目的:观察隧道技术联合结缔组织移植术治疗牙龈退缩伴非龋性牙颈部缺损（non-carious cervical lesion,NCCL）的临床疗效。方法:选择2021年1月—2022年8月间因牙龈退缩遇冷热敏感就诊于合肥市口腔医院的14例患者（26个牙龈退缩位点）为研究对象。所有患者采用隧道技术联合结缔组织移植术进行治疗,分别在术前、术后3个月、术后6个月对牙龈退缩量（gingival receding,GR）、探诊深度（probing depth,PD）、临床附着丧失（clinical attachment loss,CAL）、角化龈宽度（keratinized gingival width,KTW）、牙体缺损深度等临床指标进行测量,评价临床疗效。结果:术后3个月和6个月,GR和CAL均显著减少（P<0.05）,KTW显著增加（P<0.05）。术后3个月完全根面覆盖率为77.00%,平均根面覆盖率为94.23%;术后6个月完全根面覆盖率为73.00%,平均根面覆盖率为93.27%。结论:隧道技术联合结缔组织移植术可用于伴NCCL的MillerⅠ类和Ⅱ类牙龈退缩的治疗,临床及美学效果显著且稳定。

Abstract: PURPOSE: To evaluate the clinical efficacy of tunnel technique combined with connective tissue grafting in the treatment of gingival recession with non-carious cervical lesion(NCCL). METHODS: Fourteen patients with 26 gingival receding sites who were admitted to Hefei Stomatological Hospital from January 2021 to August 2022 due to gingival receding and sensitivity to cold and heat were selected as the research objects. All patients were treated with tunnel technology combined with connective tissue grafting. Clinical indexes such as gingival receding (GR), probing depth (PD), clinical attachment loss(CAL), keratinized gingival width (KTW) and tooth defect depth were measured before surgery, 3 months after surgery and 6 months after surgery, respectively, to evaluate the clinical efficacy. RESULTS: At 3 and 6 months after surgery, GR and CAL were significantly decreased(P<0.05), and KTW was significantly increased(P<0.05). Three months after operation, the complete root coverage rate was 77.00%, and the average root coverage rate was 94.23%. At 6 months after operation, the complete root coverage rate was 73.00%, and the average root coverage rate was 93.27%. CONCLUSIONS: Tunnel technique combined with connective tissue grafting can be used for the treatment of MillerⅠ and Miller Ⅱ gingival receding with NCCL, and the clinical and aesthetic results are significant and stable.
