两种材料修复老年牙体楔状缺损临床疗效观察

目的观察并比较FX玻璃离子和光固化树脂两种材料修复老年牙体楔状缺损的临床效果。方法196例患者共502楔状缺损患牙,每个患者都随机选一侧患牙,采用FX玻璃离子充填修复,另一侧采用光固化树脂修复,连续观察1年,比较其效果。结果采用FX玻璃离子修复257颗牙,成功243颗,成功率94.5%。采用普通光固化树脂充填修复245颗患牙,成功197颗,成功率80,4%。结论FX玻璃离子修复牙体楔状缺损远期效果明显优于光固化树脂,是一种较理想的楔状牙体缺损修复材料。

Observation of Clinical Effect of Treating Teeth's Wedge-Shaped Defects in Elderly by Using Two Kinds of Material

Objective To observe and compare the clinical effects of Glasionomer cement FX material and other two composite resin materials on curing old people with wedge-shaped defect.Methods Of the 196 patients with a total of 502 teeth of wedgeshaped defect,each patient,selected at random,was filled and repaired with glasionomer(glass ionomer) cement FX material for one side's teeth,and with light-cured composite resin for the other side.All the patients were continually observed for one year so that their effects could be compared.Results For the 257 teeth filled and repaired by using glasionomer cement FX material,243 succeeded in restoration.For the 245 teeth filled and repared by using light-cured composite resin materials,197 succeded in restoration.Conclusion With regard to long-term effect,glasionmer cement FX is superior to ligbt-cured composie resin material in treating the wedge-shaped defect and thus an ideal filling material for tooth repair.
