摘　　要：对经酸蚀及非酸蚀的树脂材料修复上颌切牙缺损的疗效进行对比分析。选择120颗患牙。分别用普通光固化复合树脂(酸蚀组)和Dyract复合体(非酸蚀组)充填治疗,随访1a,分析临床效果。发现2组固位效果无显著性差异,但非酸蚀组充填中至深龋时,对牙髓刺激性显著小于酸蚀组(P<0.05)。表明非酸蚀型树脂材料与酸蚀型相比,具有对牙髓刺激小、粘接性强、成功率高且操作简捷等优点。To analyse and compare the effects of the resin materials of etched and nonetched groups in restoring the defect of maxillary incisor. 120 teeth were divided into two groups and filled by two kinds of materials. .One year follow up result was studied. The effects of retention had no significant difference between the two groups, but the nonetched group had a lower stimulation to the pulp than the other one in restoring middle to deep caries. Compared to the etched group, the nonetched materials of resin has lower stimulation to pulp, more adhesion and higher success rate.
