摘要
目的观察复合树脂嵌体修复磨牙缺损的临床疗效。方法选择163例磨牙缺损患者的200颗患牙，将其分为2组，每组患牙100颗。分别采用直接法复合树脂嵌体和复合树脂直接充填修复患牙。于修复完成6个月和5年复诊。采用美国公共卫生署修复体临床评价标准对患者口内充填体进行疗效评价。结果修复后6个月，嵌体修复成功率为91．8％（90／98），树脂直接充填成功率为91．8％（89／97），经Х^2检验两者临床疗效差异无统计学意义（P〉0．05）。修复后5年，嵌体修复成功率为87．9％（80／91），树脂直接充填修复成功率为67．4％（60／89），Х^2检验显示嵌体的临床疗效优于树脂直接充填，差异有统计学意义（P〈0．05）。结论复合树脂嵌体修复磨牙缺损临床疗效良好，其长期临床疗效显著优于传统复合树脂直接充填。
Objective To evaluate clinical effect of composite inlays in the defective molars. Methods A total of 200 defective molars from 163 patients were divided into two groups, including 100 molars of each. One group was restored with the direct composite inlays and another group with the traditional composite fillings. All the restorations were evaluated in oral cavity after 6-month and 5-year filling or insertion with United States public health service criterions. The data were analyzed using SPSS 11.0 software with the chi-square test. The significance level was set at 5%. Results In clinical service for 6 months, the successful rate of composite inlays was 91.8% （90/98） and the corresponding figure for traditional composite fillings was 91. 8% （ 89/97 ） , but there was no statistically significant difference （P 〉 0.05）. In clinical service for 5 years, the successful rate of composite inlay was 87.9% （80/91）, the corresponding figure for the traditional composite fillings being 67.4% （60/89）and the difference was statistically significant （ P 〈 0.05 ）. Conclusions In clinical, the defective molars can be well restored with the direct composite inlays. Especially in the long-term clinical service, the composite inlays show significant superiority over the traditional composite fillings.
