不同根充方式对冠修复后基牙疼痛的影响

Effect of Different Root Canal Filling Methods on Abutment Pain After all Crown Restoration

目的研究一次法根充和分次法根充后行全冠修复的病例,一定时期内基牙根尖周反应情况。方法随机选取需要进行根管治疗的后牙,分别用一次法和分次法完成根管预备和充填,暂封后行全冠修复,观察两种根充方法对全冠修复后基牙根尖反应的影响。结果两组患者的根管充填方式与全冠修复后基牙疼痛反应差异无统计学意义。结论在严格的病例选择和规范操作前提下,一次法根充在临床就诊次数和效果上更有优势,值得推广。

Objective To study the periapical reactions of abutment teeth undergone full crown restoration during a certain period when root canals of the teeth have been filled by one - visit method or two - visit method. Methods We selected the posterior teeth which need root canal therapy randomly, completed the root canal preparation and filled with two methods respectively. We repaired the teeth af- ter temporary closure. We observed the influence on the pain reaction at abutment teeth caused by the two root canal filling methods after the all crown restoration. Results There was no statistically difference in abutments pain response between the two groups. Conclusion After strict case selection and standardization of operations, one - visit method has more advantages in the clinical medical visits and effect. It is worth promoting.
