目的比较两种不同根管冲洗方法联合机用镍钛ProTaper在老年人慢性根尖周炎的一次性根管治疗上的临床效果。方法选取我院口腔科就诊的年龄大于60岁的患者100例,随机分为两组,两组患牙都用机用镍钛ProTaper根备后,超声冲洗组用2.5%次氯酸钠和生理盐水超声冲洗根管,常规冲洗组用2.5%次氯酸钠和生理盐水注射器根管冲洗;患者在术后7天复诊,对患者进行临床检查并进行记录;术后6个月和12个月回访,进行临床及X线片检查对根管治疗的疗效进行评价。结果术后7天,两组患者疼痛严重程度比较无显著差异(P>0.05);术后6个月,两组治愈率差异无显著性意义(P>0.05),但12个月后常规冲洗组治愈率低于超声冲洗组(P<0.05)。结论对于老年人慢性根尖周炎的一次性根管治疗,使用超声冲洗联合机用镍钛ProTaper近远期疗效稳定,可减少患者复诊次数,缩短疗程,具有良好的临床效果,值得推广。
Objective To compare the clinical effects of two different root canal irrigation methods combined with NiTi ProTaper for one-time root canal therapy of chronic apical periodontitis in the elderly. Methods A total of 100 patients aged> 60 years who were admitted to our hospital for stomatology were randomly divided into two groups. The teeth of both groups were treated with Nitro-titanium ProTaper root. Ultrasonic washing group was infused with 2.5% sodium hypochlorite and saline The root canal and conventional irrigation group were treated by root canal irrigation with 2.5% sodium hypochlorite and saline syringes. The patients were followed up 7 days after operation, and the patients were clinically examined and recorded. The patients were followed up 6 months and 12 months after operation, Evaluation of the efficacy of endodontic treatment is evaluated by line inspection. Results There was no significant difference in the severity of pain between the two groups (P> 0.05) 7 days after operation. There was no significant difference in the cure rate between the two groups at 6 months after operation (P> 0.05) Group cure rate was lower than ultrasonic washing group (P <0.05). Conclusion For the elderly with chronic apical periodontitis percutaneous root canal therapy, the use of ultrasonic irrigation combined with mechanical nickel-titanium ProTaper short-term stable effect, can reduce the number of referrals and shorten the course of treatment, with good clinical results, it is worth promoting.
