纳米复合树脂和光固化复合树脂材料用于前牙美容修复的效果比较

Effect of Nano- Composite Resin Material and Light- Cured Composite Resin Material on Cosmetic Restoration of Anterior Teeth

目的比较纳米复合树脂材料和光固化复合树脂材料用于前牙美容修复的效果。方法选择接受前牙美容修复的患者100例作为研究对象,分别使用光固化复合树脂材料及纳米复合树脂材料,比较治疗后牙齿敏感发生率及自觉疼痛评分差异。结果观察组治疗后1 d、1周、1个月牙齿敏感发生率分别为8.00%,6.00%,4.00%,均明显低于对照组(P<0.05);平均疼痛评分为(2.63±0.72)分,并发症发生率为22.22%,均明显低于对照组(P<0.05);优良率为88.00%,满意度为92.00%,均明显高于对照组(P<0.05)。结论纳米复合树脂材料用于患者前牙美容修复可有效降低近期牙齿敏感发生率,减轻自觉疼痛感受,优于光固化复合树脂材料。

Objective To compare the effect of the nano-composite resin material and the light-cured composite resin material on cosmetic restoration of anterior teeth. Methods The 100 patients receiving cosmetic restoration of anterior teeth were selected as the research subjects and used the light-cured composite resin materials and the nano-composite resin materials respectively. The occur-rence rates of the tooth sensitivity and the perceived pain scores after therapy were compared between the two kinds of materi-als. Results The occurrence rates of the teeth sensitive on 1 d' 1 week' 1 month after treatment in the observation group were 8. 00%' 6. 00% and 4. 00% respectively' which were significantly lower than those in the control group ( P﹤0. 05 ) . The average pain scores in the observation group were ( 2. 63 ± 0. 72 ) and the occurrence rate of complications was 22. 22%' which were significantly lower than those in the control group ( P﹤0. 05 ) . The excellent rate in the observation group was 88. 00% and the satisfaction was 92. 00%' which were significantly higher than those in the control group( P﹤0. 05). Conclusion Nano-composite resin can effectively reduce the oc-currence rate of the tooth sensitivity and alleviate the perceived pain' which is superior to the light-cured composite resin material.
