目的:探讨自固化磷酸钙根管封闭剂1次根充法根充前牙的临床观察。方法:选择120颗前牙患有牙髓炎、根尖周炎,采用自固化磷酸钙根管封闭剂1次根充法根充患牙。观察术后1周的疼痛程度及2年后的临床情况,评价疗效。结果:术后1周,出现Ⅰ级疼痛3例,Ⅱ级疼痛2例。随访观察2年后自固化磷酸钙根管封闭剂1次根充法根充前牙显效115例、有效4例、无效1例,成功率99.1%。结论:自固化磷酸钙根管封闭剂是具有密封性、抑菌性、对根尖周组织无刺激性,而且有骨诱导性和良好生物相容性的根充材料,该材料不染色牙齿,X线阻射,不引起根尖周组织的免疫反应,是前牙根管治疗1次根充法的有效材料。
Objective: To investigate the clinical observation of root-filling with root-filling with self-curing calcium phosphate root canal blocker. Methods: 120 anterior pulp with pulpitis and periapical periodontitis were treated with root-filling with self-curing calcium phosphate root canal blocker. The degree of pain after 1 week and the clinical situation after 2 years were observed to evaluate the curative effect. Results: One week after operation, there were 3 grade Ⅰ pain and 2 grade Ⅱ pain. Follow-up observation of 2 years after self-curing calcium phosphate root canal sealant 1 root filling method of root filling 115 cases were effective, 4 cases were effective, 1 case was invalid, the success rate of 99.1%. CONCLUSION: Self-curing calcium phosphate root canal sealant is a root-filling material with tightness, antibacterial activity, no irritation to periapical tissues, osteoinductive and good biocompatibility. The material does not stain the teeth, X-ray radiation, does not cause periapical tissue immune response, root canal treatment of root anterior method of effective materials.
