不同牙科修复材料生物相容性及3种材料充填恒磨牙邻面龋的临床分析

摘要

ObjectiveTo analyze the clinical effect of different dental restorative materials on the proximal dental caries of accessional teeth.MethodA retrospective analysis of clinical data of 444 patients with proximal dental caries of accessional teeth treated in our hospital from May 2010 to May 2012 was performed, according to the different iflling materials, the patients were divided into group A (glass-ionomer cement), group B (light-cured composite resin) and group C (silver amalgam), analyzed the success rate of different dental restorative materials.ResultFollowed-up 1 and 3 years respectively, the success rate of group A was signiifcantly lower than that of group B and group C (P<0.05). After 1 years of restoration,, there was no signiifcant difference in the success rate between group B and group C (P>0.05); after 3 years of restoration, the success rate of group B was higher than group C (P<0.05).ConclusionLight-cured composite resin is helpful to improve the success rate of proximal dental caries of accessional teeth, and it is worth to be popularized in clinic.%目的：研究并分析不同牙科修复材料充填恒磨牙邻面龋的临床效果。方法回顾性分析2010年5月至2012年5月收治的444例恒磨牙邻面龋患者的临床资料。按照充填材料不同将入选患者分为A组（玻璃离子水门汀充填）、B组（光固化复合树脂充填）、C组（银汞合金充填），分析不同牙科修复材料对患牙的修复成功率。结果修复后1年和3年复诊，A组患牙修复成功率明显低于B组和C组（P＜0.05）。修复后1年，B组与C组患牙修复成功率比较差异无显著性（P＞0.05）；修复后3年，B组患牙修复成功率高于C组（P＜0.05）。结论光固化复合树脂有助于提高恒磨牙邻面龋的修复成功率，值得临床推广。
