摘 要 目的：比較對牙體牙髓病患者采用多次根管療法與一次性根管療法的效果。方法：收集2014年3月—2016年8月治療的牙體牙髓病患者50例，隨機(jī)分為對照組和觀察組各25例。對照組接受多次根管治療，觀察組接受一次性根管治療，比較兩組臨床療效、疼痛程度評分以及并發(fā)癥發(fā)生率。結(jié)果：治療后觀察組的總有效率為96.0%（24/25），對照組為72.0%（18/25），組間差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。在改善疼痛方面，觀察組的優(yōu)良率為92.0%（23/25），對照組為64.0%（16/25），組間差異有統(tǒng)計(jì)學(xué)意義（P<0.05）。觀察組的并發(fā)癥發(fā)生率為12.0%（3/25），明顯低于對照組的40.0%（10/25，P<0.05）。結(jié)論：一次性根管治療能使牙體牙髓病患者獲得更佳療效，并降低治療后的疼痛程度和并發(fā)癥發(fā)生率，有助于患者的預(yù)后，值得推廣應(yīng)用。

ABSTRACT Objective： To compare the effect of multiple and disposable root canal therapies in the treatment of the patients with dental pulp diseases. Methods： Fifty cases of dental pulp disease treated in the hospital from March 2014 to August 2016 were collected and divided into a control group and an observation group with 25 cases each. The control group received multiple root canal therapy and the observation group received disposable root canal treatment. The clinical treatment effects， pain scores and rates of complications were compared. Results： After treatment， the total efficiency of the observation group was 96.0%（24/25） and that of the control group was 72.0%（18/25） and the difference between the two groups was statistically significant（P<0.05）. In the improvement of pain， the excellent rate of the observation group was 92%（23/25） and that of the control group was 64%（16/25） and the difference between the two groups was statistically significant（P<0.05）. The complication rate of the observation group was 12%（3/25）， which was significantly lower than that of the control group 40.0% （10/25， P<0.05）. Conclusion： Disposable root canal therapy can make patients with dental pulp disease get better treatment effect and reduce the degree of pain and complications after treatment， which helps to improve their prognosis and it is worthy of popularization and application.

牙體牙髓病包括齲病、牙齒硬組織磨損、根尖周病、牙齒感覺過敏癥等，由于患牙出現(xiàn)的劇烈疼痛，對患者的生活、工作甚至睡眠造成嚴(yán)重影響[1]。有研究報(bào)道牙體牙髓病常由專性厭氧菌、兼性厭氧菌等感染引發(fā)，部分患者可由物理刺激、藥物刺激、創(chuàng)傷等因素而發(fā)病[2]。根管治療是牙體牙髓病、根尖周病的主要治療方法，可清除已壞死的牙體和牙髓，進(jìn)行密實(shí)填充，從而有效消滅感染路徑，并促進(jìn)組織愈合[3]。但是，傳統(tǒng)的多次根管療法治療周期較長，患者需頻繁就診，因此治療依從性不高[4]。本研究比較多次根管療法和一次性根管療法治療牙體牙髓病的療效，現(xiàn)報(bào)道如下。
