光固化复合体修复楔状缺损疗效观察

Evaluation of wedged-shaped defects repaired by Dyract compomer

目的 评价光固化复合体修复楔状缺损的临床疗效。方法 将 195例计 6 2 4颗牙随机分成治疗组和对照组 ,治疗组用光固化复合体修复 ,对照组用光固化复合树脂修复。结果 结果显示光固化复合体与牙面的粘接性强 ,对牙髓的刺激性小。 12个月后复查显示 ,治疗组成功率达 95 .6 % ,对照组成功率为80 .1% ,两组有显著差异 (P <0 0 1)。结论 可以认为光固化复合体是一种修复楔状缺损的新型理想材料。

Objective To evaluate the clinical effect of wedged shaped defects repaired by Dyract compomer. Method 624 teeth from 195 patents with wedged shaped defects was randomly divided into experimental group and control group .Experimental group was treated by Dyract compomer and control group was treatedby the light cured composite resins. Result The results showed that Dyract compomer was better adhesion to tooth substance and less stimulation to dental pulp than the light cured composite resins was. The success rate was 95.6% for experimental group and 80.1% for control group after 12 months ,and there was significant difference between the two groups (P<0.01). Conclusion This indicates that Dyract compomer is one kind of ideal material to repair wedge shaped defects.
