摘要
目的评估复合树脂充填治疗后牙牙体缺损的远期效果。方法选取2009年1月~2012年1月于本院接受治疗110例乳磨牙大面积缺损患儿作为研究对象,将患者按照分层随机抽样法分为对照组与观察组,各55例（55颗患牙）。对照组采用玻璃离子水门汀填充治疗,观察组应用复合树脂修复填充方案,评估两组的牙体修复效果,对患者实施为期2年的随访调查,评估其远期疗效。结果观察组50例获得随访,成功41例,占82.0%,缺陷5例,占10.0%,失败4例,占8.0%,对照组49例获得随访,成功29例,占59.2%,缺陷9例,占18.4%,观察组的远期疗效明显优于对照组（P〈0.05）;观察组继发龋4例,并发症发生率为8.0%,对照组继发龋11例,牙本质过敏1例,修复体折裂2例,牙髓病变1例,整体并发症发生率为30.6%,明显高于观察组的8.0%,且对照组的继发龋发生率明显高于观察组（P〈0.05）。结论复合树脂充填治疗乳磨牙缺损较玻璃离子水门汀填充法的远期效果更优,填充成功率更高,且患者口腔并发症发生率低。
Objective To evaluate the long-term effect of composite resin filling in the treatment of posterior teeth defect. Methods From January 2009 to January 2012,110 children with extensive-defect of primary molar teeth treated in our hospital were selected as research objects.By a stratified random sampling,they were evenly divided into control group and observation group,and there were 55 defected teeth in each group.In control group,glass ionomer cement（GIC） filling was used, while in observation group,composite resin filling for restoration was applied.The restoration effect of molar teeth was evaluated in both groups as well as long-term effect after 2-years follow-up survey. Results There were 50 cases accepting follow-up in observation group.The number of cases in success,defect,and failure was 41（82.0%）,5（10.0%）,and 4（8.0%） respectively.In control group,49 patients agreed on follow-up.They were successful in29 cases accounting for 59.2% and defect in 9 cases for 18.4%.Long-term effect in observation group was greatly superior to that in control group（P〈0.05）.4 cases occurred with secondary caries in observation group and the incidence rate of complications was 8.0%.There were secondary caries in 11 cases,dentin hypersensitivity in 1 case,repair body fracture in 2 cases,and endodontic lesion in 1 case.The incidence rate of overall complication（30.6%） was significantly higher than that of 8.0% in observation group.The incidence rate of secondary caries in control group was obviously higher than that of observation group（P〈0.05）. Conclusion In the treatment of primary molar defect,composite resin filling obtains a better long-term effect,a higher success rate of filling,and lower incidence rate of complication in oral cavity in comparison with that in the GIC filling.
