摘要： 目的 观察正畸分牙技术用于早期邻面龋复合树脂充填治疗时的临床疗效。方法 选择76例患者的120颗邻面龋患牙为研究对象,随机分为分牙修复组和常规修复组,分牙修复组采用橡皮分牙圈分牙3 d后行树脂充填,常规修复组直接行树脂充填。术后即刻对比两组窝洞类型,术后1周、l年复诊,使用改良美国公共卫生署的临床修复体质量评估系统评价两组的充填效果。结果 分牙修复组共充填窝洞58个,其中单面洞50个,双面洞8个;常规修复组共充填窝洞62个,其中单面洞14个,双面洞48个,分牙修复组单面洞的比例明显高于常规修复组（P<0.05）。术后1年,在充填体完整性方面,分牙修复组与常规修复组的成功率分别为100%和96.61%,差异无统计学意义（P>0.05）;在继发龋方面,分牙修复组成功率为94.64%,高于常规修复组（84.75%）,但差异无统计学意义（P>0.05）;在边缘着色、食物嵌塞及牙龈炎症评价指标方面,分牙修复组的成功率均高于常规修复组,差异有统计学意义（P<0.05）。结论 在复合树脂修复早期邻面龋洞前先分牙,有利于精确去龋,保留更多牙体组织,并且有利于对充填体进行精细抛光,提高临床疗效。

Abstract: Objective To evaluate the clinical effect of orthodontic elastic separators on early interproximal caries restorated by composite resin. Methods Total 120 teeth with interproximal caries from 76 patients were included and were randomly divided into orthodontic separator techniques group or routine repair group. The teeth in routine repair group were prepared and filled by traditional approach, and those in orthodontic group were prepared and filled by traditional approach but following used separators to divide teeth for 3 days. The types of cavity were compared after treatment. The clinical evaluation was performed according to modified United States Public Health Service criteria at one week and one year after treatment. Results Fifty-eight cavities including 50 simple cavity and 8 double-faced cavity were filled in orthodontic group, and 62 teeth including 14 single cavity and 48 double-faced cavity were filled in routine group, the ratio of simple cavity in orthodontic group are significantly higher than that in routine group(P<0.05). After one year, there are no significant difference of integrity of the restorations in orthodontic and routine groups, which success rate were 100% and 96.61% respectively(P>0.05), and the success rate without secondary caries in orthodontic group was 94.64%, higher than that of routine group(84.75%), without statistical difference(P>0.05). But the success rate of marginal discoloration, food impaction and gingivitis evaluation indicators in orthodontic group were higher than routine group(P<0.05). Conclusion Using orthodontic elastic separators was conducive to accurate preparation, retained more tooth tissues, and available fine polishing, which could improve the clinical curative effect.
