摘要
目的:通过应用玻璃离子水门汀材料、光固化氢氧化钙垫底后光固化复合树脂材料及光固化氢氧化钙垫底后光固化流动树脂材料三种不同的楔状缺损修复方式,比较对照这三种修复方式的临床疗效。方法:临床选择180颗尖牙或是前磨牙牙齿楔状缺损需要修复的患者64例,分为A、B、C三组,每组60颗牙齿,分别采用玻璃离子水门汀材料、光固化氢氧化钙垫底后光固化复合树脂材料、光固化氢氧化钙垫底后光固化流动树脂材料三种方法修复楔状缺损,并于术后6个月随访观察疗效。结果:充填后6个月A、B、C组三种方法修复楔状缺损的成功率分别为81.67%、93.33%和95.00%,其中B、C两组高于A组,差异有统计学意义(P<0.05),而B、C两组之间差异无统计学意义(P>0.05)。结论:对牙本质暴露的牙齿楔状缺损光固化氢氧化钙垫底后光固化流动树脂材料具有较高的修复效果。
Objective： To observe and compare the clinical curative effect of three kinds of restorations of using glass ionomer cement materials, light curing calcium hydroxide under light cured composite resin materials and light curing calcium hydroxide under light curing resin flow materials. Method： 180 cases of patients with canines and 64 cases of patients with premolars tooth wedge-shaped defects who were in need repair were selected and divided into A, B, C 3 groups, each group of 64 teeth, the patients were received the treatment of three kinds of restorations of using glass ionomer cement materials, light curing calcium hydroxide under light cured composite resin materials and light curing calcium hydroxide under light curing resin flow materials respectively. The patients were followed up 6 months after operation and the clinical efficacy were observed.Result： The success rates in A, B, C group of 3 methods for restoring wedge-shaped defect were 81.67%, 93.33% and 95.00% after 6 months, of where B, C two group was higher than that in A group and the differences were statistically significant （ P〈0.05 ）, but there was no significant difference between group B and group C （ P〉0.05 ）. Conclusion： Light curing calcium hydroxide under light cured composite resin materials in treatment of patients with the wedge-shaped teeth dentin exposure has higher repair effect.
