不同程度根管填充对急性牙髓炎患者近远期疗效的影响

Effects of different degree of toot canal filling on short-term and long-term outcome of acute pulpitis patients

目的观察急性牙髓炎患者不同程度根管填充的近远期疗效。方法将河南省省直第二医院2015年7月至2016年3月期间收治的96例急性牙髓炎患者随机分为A组、B组和C组,A组患者根管欠量填充,B组患者根管适量填充,C组患者根管超量填充,对三组患者进行为期6个月的随访,评价三组患者的近远期疗效。结果 B组患者治疗后1个月的疼痛率为8.6%,低于A组患者30.0%和C组患者的32.3%(P<0.05),A组患者和C组患者治疗后1个月的疼痛率比较无明显差异(P>0.05)。B组患者治疗后2个月的咀嚼效率为(0.814±0.113),高于A组患者和C组患者的(0.705±0.109)和(0.692±0.101),A组与C组比较存在的差异无统计学意义(P>0.05)。B组患者治疗后3个月、6个月的治疗总有效率分别为91.4%、85.7%,与A组患者的80.0%、70.0%和C组患者的71.0%、58.1%比较存在的差异均具有统计学意义(P<0.05)。A组患者治疗后3个月、6个月的总有效率高于C组(P<0.05)。结论对急性牙髓炎患者实施适度根管填充治疗,可获得确切的近远期疗效。

Objective To observe the short-term and long-term effect of different degrees of root canal filling in patients with acute pulpitis. Methods Ninety-six case of patients with acute pulpitis were randomly divided into three groups：group A,group B,group C,three groups were followed up for 6 months. The short-term and long-term curative effects of the three groups were evaluated. Results The pain rate was 8. 6% in one month after treatment,30. 0% in A group and 32. 3% in C groups（ P 〈 0. 05）. In group A and group C,the pain rate was 1 month after treatment pain rate was no significant difference（ P 〉 0. 05）. The masticatory efficiency at 2 months after treatment was（ 0. 814 ±0. 113）,which was higher than that in group A and group C（ 0. 705 ± 0. 109） and（ 0. 692 ± 0. 101）,and there was no significant difference between group A and group C Statistical significance（ P 〉 0. 05）. The total effective rates in group B were 91. 4% and 85. 7% at 3 months and 6 months after treatment respectively,which were significantly higher than those of the three groups（ 71. 0% vs 58. 0% ,80. 0% and 70. 0% ,respectively）. With statistical significance（ P 〈 0. 05）. The total effective rates of group A and group C were higher than those of group C（ P 〈 0. 05）.Conclusion Appropriate root canal filling in patients with acute pulpitis can obtain definite short-term and long-term curative effect.
