VITA树脂嵌体修复儿童和青少年第一磨牙缺损的临床评价

Clinical evaluation of VITA resin inlay on restoration of the first permanent molars for children and adolescents

目的评价VITA树脂嵌体修复儿童和青少年第一恒磨牙大面积缺损的临床疗效。方法选择6~16岁儿童和青少年大面积缺损的第一恒磨牙178颗,随机分为2组,试验组采用VITA树脂嵌体修复,对照组采用复合树脂直接充填,术后1年复查,评价临床疗效,应用SPSS 16.0软件包进行统计学分析。结果试验组的修复成功率为97.78%,高于对照组(84.09%),有显著性差异(P<0.01)。试验组和对照组的上下颌牙的治疗有效率无统计学差异(P>0.05)。试验组的男女孩治疗有效率无显著性差异(P>0.05),而对照组男孩治疗有效率明显低于女孩(P<0.01)。结论 VITA树脂嵌体修复牙体大面积缺损的临床疗效显著优于树脂直接充填,能满足临床需求。

Objective To evaluate the clinical effects of VITA resin inlay on restoration of the badly broken-down first permanent molars for children and adolescents. Methods 178 badly broken-down first permanent molars aged from 6 to 16 years old were selected and randomly assigned into 2 groups. VITA resin inlay restorations were used in the test group,composite resin direct fillings were used in the control group. Clinical assessment was made after treatment one year later. All data were statistically analyzed by SPSS 16.0.Results The restoration success rate of test group was 97. 78%,significantly higher than that of control group 84. 09%（P 〈0. 01）.There was no significant difference in maxillary and mandible teeth between test group and control group（P〉0.05）. There was no significant difference in effective rate between male and female in the test group（P 〉0.05）,but the restoration success rate of male was significantly lower than that of female in the control group（P〈0.01）. Conclusion The clinical effects of VITA resin inlay on restoration of the badly broken-down molar are superior to composite resin direct filling. The clinical requirement can be satisfied.
