摘要
评价旋转镍钛器械Mtwo在老年患者根管治疗中应用的临床效果。随机选取老年患者中因牙髓炎或根尖周炎需行根管治疗的患牙80例,均分为2组:M组使用旋转镍钛器械Mtwo、改良步退法预备根管;K组使用手用不锈钢K锉、步退法预备根管,2组均采用冷侧压法充填根管。M组能维持根管原有的走向,无根管偏移、台阶、侧穿等并发症;K组并发症的发生率显著多于M组(P<0.05)。M组操作时间短,术后疼痛少。在老年患者的根管治疗中,使用旋转镍钛器械Mtwo进行根管预备,快速、有效,成形效果好,值得临床推荐。
To evaluate the clinical effects of rotary nickel-titanium instruments Mtwo in root canal therapy in the aged patients. Using stepback technique,80 teeth with pulpal and periapical involvement were instrumented by Mtwo in the M group, and by K file in the K group. Mtwo could keep the original curvature and flow of the root canals. No transportation, apical blockage, ledge or perforation was found in the M group. There was more complications in the K group than in the M group. The operative time was shorter and posttreatment pain seldom occurred in the M group. With rotary NiTi instruments Mtwo for seniles root canals treatment, root canals can be prepared effectively and quickly, and is worth of clinical application.
