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对比研究

目的:分析与比较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。方法:选取2013年9月至2016年10月于我院进行前牙美容修复的患者62例(115颗牙),平均分为甲组和乙组。甲组予以纳米复合树脂修复治疗,乙组则予以光固化复合树脂修复治疗。分析比较两组患者的治疗成功率、修复优良率、患者满意度、自觉疼痛程度、敏感发生率、并发症的发生情况及牙周相关指标。结果:甲组的治疗成功率(93.55%)显著高于乙组(70.97%),修复效果等级显著优于乙组,修复效果优良率(96.77%)也显著优于乙组(67.74%)。甲组的牙龈指数、龈沟出血指数、菌斑指数和牙松动度均显著低于乙组。两组患者的VAS评分均随着时间延长降低,在修复后1周、1个月、3个月时,甲组患者的VAS评分均显著低于乙组。甲组的患者满意度高于乙组,并发症总发生率显著低于乙组(P0.05)。结论:纳米复合树脂对前牙美容修复较光固化复合树脂有更好效果,且患者牙齿敏感发生率低、自觉疼痛程度小、并发症少,患者牙周相关较好,患者满意率高。

A Comparative Study on the Nano-composite Resin and Light-cured Composite Resin in the Cosmetic Repair of Anterior Teeth

ABSTRACT Objective: To analyze and compare the effect of nano-composite resin and light-cured composite resin materials on the cosmetic repair of anterior teeth. Methods: From September 2013 to October 2016, 62 patients (115 teeth) treated with anterior teeth cos- metic repair in our hospital were selected and divided into group A and group B. Group A was treated by nanocomposite resin, and group B was treated by light-cured composite resin. The treatment success rate, excellent and good rate of repair, periodontal indexes, and pa- tient''s satisfaction, incidence of tooth hypersensitivity, spontaneous pain score and complications were analyzed and compared between the two groups. Results: The success rate of treatment in group A (93.55%) was significantly higher than that of group B (70.97%)(P<0.05), and the repair grade was significantly better than that of the group B(P<0.05), and the excellent and good rate of repair (96.77%) was significantly higher than that of group B (67.74%)(P<0.05). The gingival index, sulcus bleeding index, plaque index and tooth mobility degree were significantly lower in group A than those of the group B(P<0.05). The VAS scores of both groups decreased with time. At 1 week, 1 month and 3 months after repair, the VAS scores of group A were all significantly lower those of group B(P<0.05). Patients'' sat- isfaction of group A was higher than that of the B group(P<0.05), the overall incidence of complications was significantly lower than that of the group B(P<0.05). Conclusion: Compared with the light-cured composite resin, the nanocomposite resin was better for the repair of anterior teeth, with excellent indexes of the abutment, low degree of conscious pain, low incidence of tooth sensitivity, fewer complica- tionsand high satisfaction.
