摘要:

目的 探讨大面积牙体缺损乳磨牙根管治疗后树脂嵌体修复的临床效果,以期为大面积龋坏乳磨牙的修复提供参考。方法 选择32例患儿共38颗乳磨牙为研究对象,根管治疗后行复合树脂嵌体间接修复,根据改良式USHPS评价标准分别于修复后6、12、18个月对患牙的修复体存留、边缘完整性、牙龈状态、解剖形态、继发龋五项指标进行临床效果评价。结果 18个月的随访期内,38颗患牙中36颗修复成功,其所有评价项目均达A或B级。修复后6个月, 1颗修复体脱落,修复成功率为97.37%(37/38),修复后12个月修复成功率为97.37%(37/38),修复后18个月,新增 1颗失败修复体(边缘完整性和解剖形态为C级),修复成功率为94.74%(36/38)。树脂嵌体修复后6、12、18个月的修复成功率差异无统计学意义(χ 2=0.518,p=0.772)。 结论 复合树脂嵌体修复根管治疗后大面积缺损的乳磨牙能获得较好的临床效果,是乳磨牙修复的一种可选方案。

Abstract:

Objective To explore the clinical effect of composite resin inlays in repairing large areas of primary molar defects after root canal treatment to provide a reference for the restoration of carious primary molars.Methods Thirty-eight primary molars of 32 children were selected as the research objects. Indirect restoration with composite resin inlays was performed after root canal therapy. The clinical efficacy was evaluated in terms of five indices, including restoration retention, marginal integrity, gingival status, anatomical morphology and secondary caries, according to the modified USHPS evaluation criteria, at 6, 12 and 18 months after restoration.Results During the 18-month follow-up period, 36 of the 38 teeth were successfully restored, and all the evaluated items reached grade A or B. Six months after the repair, one prosthesis had fallen off, resulting in a success rate of 97.37% (37/38). The success rate remained 97.37% (37/38) 12 months after the repair; 18 months after the repair, another prosthesis had failed(Marginal integrity and anatomical morphology were grade C), reducing the success rate to 94.74% (36/38). There was no significant difference in the success rate of resin inlay repair at 6, 12 or 18 months (χ 2=0.518, p=0.772). Conclusion Composite resin inlay restoration is an alternative method for repairing primary molars with large defects after root canal treatment.
