根管填充程度对慢性根尖周炎治疗的影响

目的:比较3种根管填充程度对牙体牙髓的疗效。方法:102例牙体牙髓患者(146颗患牙)采用根管填充治疗,治疗后根据影像学显示根管填充程度分为适充组(109颗)、超充组(14颗)及欠充组(23颗),比较3组临床疗效及治疗过程中疼痛发生率。结果:适充组治疗总有效率为94.50%,均明显高于超充组的64.29%和欠充组的47.83%(P<0.01);适充组疼痛发生率为3.67%,超充组疼痛发生率为14.29%,欠充组疼痛发生率为26.09%,差异无统计学意义(P>0.05)。结论:在3种根管填充程度治疗牙体牙髓病时,以适充治疗疗效最为显著,在临床工作中应尽量避免超充以及欠充治疗。

Effect of the root canal filler in the treatment of chronic apical periodontitis

Objective:To compare the effects of 3 kinds of different amount root canal filler in the treatment of dental pulp. Methods:One hundred and two patients(146 teeth) were treated with root canal filler. After treatment,these teeth were divided into the suitable supplement group ( 109 teeth ) , excessive supplement group ( 14 teeth ) and deficient supplement group ( 23 teeth ) according to the imaging data. The clinical effects and pain incidence between 3 groups were compared. Results:The total efficiency rare in suitable supplement group(94. 50%) was significantly higher than that in excessive supplement group(64. 29%) and deficient supplement group(47. 83%)(P<0. 01). The pain incidences in suitable supplement group,excessive supplement group and deficient supplement group were 3. 67%,14. 29% and 26. 09%,respectively,the differences of those between 3 groups were not statistically significant(P>0. 05). Conclusions:Among the three kinds of different amount root canal filler,the treatment effect of suitable supplement is best,and the excessive and deficient supplement method should not be used in clinic.
