摘要： 目的: 探讨年轻恒牙牙体组织大面积缺损至龈下且需进行保髓治疗时应用正畸带环制作假壁的临床效果。方法: 选择牙体组织大面积缺损至龈下且需要进行保髓治疗的年轻恒磨牙60例,随机分为试验组与对照组,每组各30例。试验组应用正畸带环制作假壁,对照组应用传统复合树脂制作假壁,假壁制作完成后安放橡皮障,比较2组假壁临床制作时间、使用橡皮障后假壁的稳固程度及治疗前后牙周健康情况[龈沟出血指数（SBI）、牙龈指数（GI）、龈沟探诊深度（SPD）]。采用GraphPad Prism 5.0软件包对数据进行统计学分析。结果: 试验组的假壁制作时间为（6.01±0.34） min,短于对照组的（12.02±0.53） min,差异具有统计学意义（P<0.05）。2组假壁的稳固程度及牙周健康指标差异无统计学意义（P>0.05）。结论: 对于年轻恒牙大面积缺损至龈下且需进行保髓治疗的病例,正畸带环可以缩短假壁制作时间,提供比较稳定的固位,并且短时间内对患牙的牙周健康未产生明显影响,可为儿童口腔临床工作中假壁的制作提供新的思路。

Abstract: PURPOSE:To investigate the clinical application value of making false wall with orthodontic band when a large area of tissue defects of young permanent teeth is subgingival level and vital pulp therapy is required. METHODS: A total of 60 cases of young permanent molars with large tissue defects to subgingival level and requiring vital pulp therapy were selected and randomly divided into experimental group and control group, with 30 cases in each group. Orthodontic band was made in the experimental group, while traditional composite resin was used in the control group, rubber barrier was placed after the fabrication of the false wall. The clinical fabrication time, stability of the false wall after the use of rubber barrier and periodontal health conditions(SBI, GI, SPD) of the affected tooth before and after operation were compared between the two groups.Graph Pad Prism 5.0 software package was used for statistical analysis. RESULTS: The fabrication time of the experimental group was (6.01±0.34) min, which was shorter than that of the control group (12.02±0.53) min, and the difference was statistically significant(P<0.05). But the stability of the false wall and the influence on the periodontal health of the affected teeth were not significantly different between the two groups(P>0.05). CONCLUSIONS: For the cases of young permanent teeth with large area defects to subgingival and requiring vital pulp therapy, orthodontic band can shorten the fabrication time of false wall, provide relatively stable retention, with no significant effect on the periodontal status of the affected teeth in a short time. It can provide a new idea for the fabrication of false wall in pediatric dental clinical work.
