2种方法治疗急性牙髓炎的长期疗效对比研究

Comparative study on long term effects of two kinds of method for treating acute pulpitis

目的比较在急性牙髓炎患者中采用一次性根充法与分次根充法治疗的长期效果。方法选取2011年9月至2012年9月该院口腔科收治的急性牙髓炎患者80例,按照随机数字分表法分成观察组与对照组,每组各40例,分别给予一次性根充法与分次根充法治疗,比较两组患者治疗1周后的疼痛情况及治疗2年后的临床疗效。结果观察组治疗1周后的疼痛评定优良率为10.00%,略高于对照组患者的8.00%,差异无统计学意义(P>0.05);观察组治疗2年后的成功率为94.00%,显著高于对照组患者的78.00%,差异有统计学意义(P<0.05)。结论采用一次性根充法治疗急性牙髓炎患者,比分次根充法的长期疗效更显著,操作简便,值得进一步推广。

Objective To compare the long‐term effects of using one‐time root canal filling method and graded root canal filling method in treating acute pulpitis .Methods 80 cases of acute pulpitis in our hospital from September 2011 to September 2012 were selected and divided into the observation group and the control group according to the random digital table method ,40 cases in each group .The two groups were given the one‐time root canal filling meth‐od and the graded root canal filling method respectively .The pain situation after 1‐week treatment and the clinical effect in 2 years after treatment were compared between the two groups .Results The excellent and good rate of pain assessment after 1 weeks of treatment in the observation group was 10 .00% ,which was slightly higher than 8 .00%in the control group ,the difference had no statistical significance（P〉0 .05）;the success rate after 2 years of treat‐ment in the observation group was 94 .00% ,which was significantly higher than 78 .00% in the control group ,the difference was statistically significant（P〈0 .05） .Conclusion Adopting one‐time root canal filling method for trea‐ting acute pulpitis has more significant long term effect than the graded root canal filling method ,which is easy to op‐erate and deserves to be further popularized .
