扩大根尖狭窄区治疗根尖周炎临床观察

Clinical observation of expanding the apical constriction treatment of the periapical periodontitis

目的:探讨扩大根尖狭窄区治疗根尖周炎的临床疗效。方法:2010年1月-2013年10月收治根尖周炎患者80例,随机分成对照组和观察组,各40例,对照组采用传统根管治疗术进行治疗,观察组采用扩大根管狭窄区治疗术进行治疗。结果:观察组超充1例,术后持续牙龈肿胀1例,慢性牙龈炎1例。对照组欠充4例,超充6例,残余5例,术后持续牙龈肿胀7例,慢性牙龈炎8例。两组比较差异有统计学意义(P<0.05)。经过6~27个月的随访,观察组复发2例,复发率5.0%,对照组复发11例,复发率27.5%,两组比较差异有统计学意义(P<0.05)。结论:扩大根尖狭窄区治疗根尖周炎复发率低,临床疗效佳,值得推广。

Objective:To investigate the clinical effect of expanding the apical constriction treatment of the periapical periodontitis.Methods:80 patients with periapical periodontitis were selected from January 2010 to October 2013.They were divided into the observation group and the control group with 40 cases in each.The control group were given the traditional root canal therapy,while the observation group were treated with expanding the apical constriction therapy.Results:In the observation group,1 cases was over filling,1 cases continued gingival swelling after operation,and 1 cases was chronic gingivitis.In the control group,4 cases were under filling,6 cases were over filling,5 cases were residual,7 cases continued gingival swelling after operation, and 8 cases were chronic gingivitis.The difference between two groups was statistically significant(P<0.05).After 6~27 months of follow-up,2 cases were recurred in the observation group,and the recurrence rate was 5%.11 cases were recurred in the control group,and the recurrence rate was 27.5%.The difference between two groups was statistically significant(P<0.05).Conclusion:The treatment of expanding the apical constriction on periapical periodontitis had low recurrence rate and a good clinical efficacy,so it is worth promoting.
