摘要
目的:探讨金属烤瓷全冠修复老年人活髓隐裂牙适应证及临床疗效。方法:将134例老年人(60-68岁)134颗活髓隐裂牙按照疼痛性质随机分为:咬合痛组(A组)、咬合痛伴一过性冷热刺激痛组(B组)、咬合痛伴延续性冷热刺激痛组(C组),均直接进行金属烤瓷全冠修复,观察修复1周、6个月和1年后牙髓、根尖周病变的发生率。结果:A组和B组1周、6个月和1年的治愈率和有效率均高于C组;A、B组与C组间疗效差异显著(P<0.01)。结论:对于轻微咬合痛和伴一过性冷热刺激痛的患牙,可以直接金瓷全冠修复,对于伴延续性冷热刺激痛的患牙,则宜先行根管治疗术再行全冠修复。
Objective: To investigate the effect of Porcelain-fused-to-metal crown(PFM) on direct repair of cracked vital pulp teeth for old patients and to guide clinical treatment.Methods: One hundred and thirty-four cracked vital pulp teeth from 134 cases(60-68 year) were randomly divided into 3 groups according to clinical symptoms: group A defined as mild pain at occlusion,group B as pain at occlusion accompanied with transient pain to cold or hot stimulation,and group C as pain at occlusion accompanied with conti...
