摘要
目的探讨MTAD联合次氯酸钠进行超声荡洗根管治疗难治性根尖周炎感染的清洁效果和有效性。方法选取2016年1月~2018年2月我院收治的难治性根尖周炎患者62例为研究对象,随机分为实验组(n=31)和对照组(n=31)。对照组以次氯酸钠超声荡洗根管,研究组以MTAD联合次氯酸钠超声荡洗根管。根管预备前后均从根管内采样进行细菌培养和计数,计算比较两组细菌减少率。评价比较两组疼痛情况、清洁效果和疗效。结果与对照组比较,实验组根管预备后菌落计数降低,细菌减少率升高,3级和4级疼痛患者比例降低,治疗成功率提高,各指标比较,差异有统计学意义(P<0.05)。结论MTAD与次氯酸钠超声荡洗根管治疗难治性根尖周炎感染具有良好的清洁效果,大大提高了治疗有效率。
Objective To investigate the cleaning effects and effectiveness of MTAD combined with sodium hypochlorite ultrasonic root canal washing in the treatment of refractory periapical periodontitis.Methods A total of 62 patients with refractory periapical infection admitted to the hospital from January 2016 to February 2018 were randomly divided into experimental group(n=31)and control group(n=31).In the control group,the root canal was washed by sodium hypochlorite ultrasound,while in the research group,the root canal was washed by MTAD combined with sodium hypochlorite ultrasound.Before and after root canal preparation,samples were taken from the root canal for bacterial culture and counting,and the bacterial reduction rate in the two groups was calculated and compared.The pain status,cleaning effect and curative effect of the two groups were compared.Results Compared with the control group,the bacterial colony count in the experimental group was reduced after root canal preparation,The bacteria reduction rate was increased,the proportion of grade 3 and 4 pain patients was decreased,and the treatment success rate was improved,and the difference of each indicator was statistically significant(P<0.05).Conclusion MTAD combined with sodium hypochlorite ultrasonic root canal washing has a good cleaning effect in the treatment of refractory periapical periodontitis,and is greatly improving the treatment efficiency.
