目的 评价15%EDTA凝胶作为化学去腐剂对乳前牙龋齿的充填效果的影响。方法 筛选符合要求的患者120例,随机分为两组,对照组60例,试验组60例。对照组选用伢典凝胶去除龋齿腐质,试验组选用15%EDTA凝胶去除腐质。两组均应用一步法自酸蚀粘接剂Filtek Z350(3M ESPE)流体树脂充填乳牙龋损。随访1年后,依据临床疗效评估标准评价充填效果。结果 两组研究对象的基线情况差异无统计学意义(P>0.05);1年随访后,两组无失访病例,试验组和对照组充填成功率分别为99%和98%,成功率差异无统计学意义(P＞0.05)。结论 应用15%EDTA凝胶化学去腐的方式,流体树脂充填龋损,操作时间短且微创,充填效果理想。
Abstract
Objective To evaluate the filling efficacy of maxillary deciduous anterior teeth with 15% ethylene diamine teraacetic acid(EDTA) gel as chemical way to remove the decay. Methods A total of 120 patients were selected and divided into experiment group and control group with 60 patients in each group.CarisolvTM gel was used in control group and 15%EDTA gel was used to remove the decay in experiment group.Then,one step self-etching-adhesives and Filtek Z350 (3M ESPE) flowable resin was used to fill the teeth defect.During one-year follow-up period,filling efficacy were assessed in one-year follow-up period.The data recorded were analyzed by chi-square test with SPSS 19.0 software. Results No significant difference on baseline data was observed(P＞0.05).After one-year follow-up period,no patients dropped out.The success rate of dental filling in the experiment group and the control group was separately 99% and 98%.No statistically significant difference was observed with respect to dental filling efficacy(P ＞0.05). Conclusion 15%EDTA gel could be used to remove decayed tissue in the treatment of deciduous decay,with self-etching-adhesives and Filtek Z350 (3M ESPE) as dental filling.
