摘要
目的对比银汞合金、高强度玻璃离子水门汀和光固化聚合体充填Ⅱ类洞的疗效,以寻求更能实现微创美容牙科治疗(MiCD)目标的牙科充填材料。方法采用随机分组方法将148例171颗患牙分成三组,Ⅰ组采用银汞合金充填,Ⅱ组采用高强度玻璃离子水门汀充填,Ⅲ组采用光固化聚合体充填,观察5年后的临床修复效果。结果银汞合金组、高强度玻璃离子水门汀组和光固化聚合体组的五年成功率分别为71.43%(35/49)、82.98%(39/47)和94.64%(53/56),三者差异具统计学意义(P<0.05)。结论采用光固化聚合体充填后牙Ⅱ类洞可获得理想的预后,更符合现代齿科治疗MiCD理念的需求。
Objective To compare the clinical effect of silver amalgam, glass ionomer cement, and light-activated resin adhesive in filling class Ⅱ cavity, aiming at finding a dental material that can more fulfill the idea of minimally invasive cosmetic dentistry. Methods One hundred and forty-eight cases （171 tooth） of class II cavity were randomly divided into three groups： group I used silver amalgam to fill the cavity, group II used high tensioned glass ionomer cement, and group III used light-activated resin adhesive. Clinical restoration effect was assessed 5 years after the filing. Results The 5-year success rate was 71.4%,82.98%, and 94.64% for silver amalgam group, glass ionomer cement group, and light-activated resin adhesive group, respectively, and the difference was of statistical significance （P＜0.05）. Conclusion The application of light-activated resin adhesive in the filling of class Ⅱ cavity can achieve ideal prognosis, and is more in accordance with the requirement of modern minimally invasive cosmetic dentistry.
