目的评价显微根尖倒充填手术治疗难治性根尖周炎的临床疗效。方法 45例(54颗)难治性根尖周炎患者为研究对象,所有患者均进行显微根尖倒充填手术,术后3个月、1年复查,评价术后疗效。结果术后随访,成功50颗(92.6%),失败4颗(7.4%)(2颗根折,1颗因为牙周情况不佳,1颗原因不明)。牙位分布、年龄分布、性别分布间成功率比较,差异均无统计学意义(P>0.05)。结论显微根尖倒充填手术可以明显提高难治性根尖周炎的治疗成功率。
Objective To evaluate the clinical effect of microsurgical apical filling in the treatment of refractory apical periodontitis. Methods Forty-five patients with refractory periapical periodontitis were studied. All the patients underwent apical retrograde filling operation. The patients were reviewed at 3 months and 1 year after operation to evaluate the postoperative effect. Results Postoperative follow-up, 50 (92.6%) were successful, 4 failed (7.4%) (2 root fractures, 1 due to poor periodontal conditions and 1 unknown). There was no significant difference in the distribution of dental location, age distribution and gender distribution between the two groups (P> 0.05). Conclusion Microsurgical apical filling can significantly improve the therapeutic success rate of refractory apical periodontitis.
