目的探讨牙髓塑化术与根管治疗术治疗慢性根尖周炎的临床疗效。方法反复疼痛、无急性渗出的根尖周炎患者80例,分为塑化组和根管组,各40例,分别行牙髓塑化术与根管治疗术1周和1年后复查,评价其疗效。结果塑化组和根管组1周后的疼痛发生率对比差异无统计学意义(p>0.05),1年后复查两组成功率根管组高于塑化组,差异有统计学意义(p<0.05)。结论临床上用根管治疗术治疗慢性根尖周炎可取得较好疗效。
Objective To investigate the clinical effect of endodontic plastic surgery and root canal therapy in the treatment of chronic apical periodontitis. Methods Totally 80 patients with periapical periodontitis who had pain and no acute exudation were divided into plasticization group and root canal group, 40 cases in each. Pulp plasticization and root canal treatment were performed for 1 week and 1 year respectively , Evaluate its efficacy. Results There was no significant difference in the incidence of pain after one week between the plasticized group and the root canal group (p> 0.05). After 1 year, the success rate in the two groups was higher than that in the plasticized group (p <0.05), and the difference was statistically significant (p <0.05). Conclusion The clinical use of root canal therapy for chronic apical periodontitis can achieve better results.
