摘　　要：背景:大尺寸豆瓣形成型片翼片较标准成型片长,适用于牙龈退缩而牙冠相对长的老年患者牙齿修复。目的:验证大尺寸豆瓣成型片辅助修复老年磨牙邻面龋的效果。方法:将87例老年磨牙邻面龋患者随机分成2组,试验组采用大尺寸豆瓣成型片进行修复,对照组采用传统汞合金成型片进行修复。修复后立即、1个月、3个月、6个月、12个月,对比两组患者舒适满意率、修复优良率与牙龈指数。结果与结论:试验组修复后1,3,6,12个月的舒适满意率均高于对照组(P<0.05),修复后1,3,6,12个月的牙龈指数均低于对照组(P<0.05),修复后不同时间点的优良率均高于对照组(P<0.05),两组均未发生修复体脱落与折裂。结果表明大尺寸豆瓣成型片修复老年磨牙邻面龋可较好地恢复牙齿的解剖外形和邻接点,减少食物嵌塞,减轻牙龈炎症。BACKGROUND： The large watercress molded piece is longer than that of the normal molded piece, which is suitable for dental restoration of elderly patients with gingival recession and relatively long crown. OBJECTIVE： To test and verify the effect of large watercress molded piece on the auxiliary repair of approximal caries lesions in molars of the elderly. METHODS： Eighty-seven senile patients with molar approximal caries were randomly divided into two groups： those were repaired by large watercress molded piece as experimental group, and those repaired by traditional amalgam molded piece as control group. Then we compared the comfortable satisfaction rate, the excellent and good rate of repair and the gingival index between the two groups immediately, 1, 3, 6 and 12 months after repair. RESULTS AND CONCLUSION： The comfortable satisfaction rate of the experimental group was significantly higher than that of the control group at 1, 3, 6 and 12 months after repair（P〈0.05）, and the gingival index was significantly lower than that of the control group（P〈0.05）. The excellent and good rate of the experimental group was significantly higher than that of the control group at different time points after repair（P〈0.05）. No loss or fracture of the restorations occurred in the two groups. These results demonstrate that the large watercress molded piece for repairing approximal caries lesions in molars of the elderly can better restore the anatomical shape and approximal points of teeth, and reduce food impaction and gingival inflammation.
