目的:探讨老年人活髓隐裂牙应用金属烤瓷全冠修复临床效果及适应症。方法:选取本院2006年1月至2011年1月期间收治的356例老年活髓隐裂牙合计621颗为研究对象,根据患牙疼痛程度随机将患者分为咬合疼痛组(A组)104例合计215颗患牙,咬合伴过敏性冷热刺激痛组(B组)122例合计232颗患牙,咬合伴延续性冷热刺激疼痛组(C组)130例合计174颗患牙,所有患者均接受金属烤瓷全冠修复,观察患者在治疗后1个月、6个月、12个月、18个月、24个月治愈情况以及牙髓及根尖周病变及牙髓发生情况。结果:与C组相比,A组、B组术后1个月、6个月、12个月、18个月、24个月治愈率以及总有效率较高,差异有统计学意义(P<0.05)。结论:金属烤瓷全冠修复适合于轻微咬合疼痛以及咬合伴过敏性冷热刺激痛的患者,而对于咬合伴延续性冷热刺激疼痛的患者则宜先行根管治疗术再进行全冠修复。
Objective: To investigate the clinical effect and indications of metal porcelain crown restoration in elderly patients with active pulpiseal fracture. Methods: A total of 621 healthy living beings with cracked teeth were collected from January 2006 to January 2011 in our hospital. The patients were randomly divided into two groups: group A (n = 104), group B A total of 215 teeth with bite associated with allergic cold and heat stimulating pain group (group B) 122 patients with a total of 232 teeth, bite with extended cold and heat stimulation pain group (group C) 130 cases total 174 teeth, all Patients were treated with metal crown restoration, observed in patients after treatment 1 month, 6 months, 12 months, 18 months and 24 months cure as well as the pulp and periapical lesions and pulp occurrence. Results: Compared with group C, the cure rates and the total effective rates of group A and group B at 1 month, 6 months, 12 months, 18 months and 24 months after operation were significantly higher (P <0.05). CONCLUSIONS: The PFM restoration is suitable for minor bite pain and bite associated with hyperthermia and irritation pain. Patients with bite associated with persistent cold and heat pain should be treated with root canal first and then with full crown restoration.
