摘要:
目的：研究不同根管预备器械对弯曲根管预备效果的影响。方法：96例牙髓炎或根尖牙周炎患者作为研究对象，共148颗患牙，按照抽签法，分为观察A组、观察B组和对照组，各32例。观察A组Protaper机，观察B组Mtwo机，对照组不锈钢K锉，比较根管预备时间、弯曲度、疼痛反应、根管锥度、流畅度及充填效果。结果：观察A组、观察B组预备时间显著少于对照组（P<0.05）。观察A组、B组比较无显著差异（P>0.05）。预备后3组根管弯曲度均显著降低（P<0.05）。3组组间比较无显著差异（P>0.05）。观察A组、B组疼痛反应显著优于对照组（P<0.05）；观察A组、观察B组前磨牙、后磨牙的锥度和流畅度显著优于对照组（P<0.05）。观察A组（90.63%）、B组（88.89%）适充充填显著优于对照组（80.00%）（P<0.05）。结论：镍钛预备器械的弯曲根管预备快速，能够保持根管形态，提高充填效果。
Abstract:
Abstract: Objective To explore the effect of different root canal preparation instruments on the preparation of curved root canals. Methods Ninety-six patients with pulpitis or apical periodontitis were enrolled in this study, with a total of 148 affected teeth, and then the patients were randomly divided into observation group A, observation group B and control group, with 32 cases in each group. Protaper nickel titanium instrument was used for root canal preparation in observation group A, Mtwo nickel titanium instrument in observation group B, and stainless steel K file in control group. The root canal preparation time, curvature, pain response, root canal conical degree fluency and obturation quality were compared. Results The preparation time of observation groups A and B was significantly shorter than that of control group, and there was no statistical difference between observation groups A and B (P>0.05). After preparation, the curvatures of the root canals in all 3 groups were significantly lower those before preparation, and there was trivial difference among 3 groups (P>0.05). The pain responses of observation groups A and B were significantly better than that of control group (P<0.05) and moreover, observation groups A and B were significantly superior to control group in the conical degree and fluency of premolars and posterior molars (P<0.05). The obturation quality in observation groups A (90.63%) and B (88.89%) were significantly better than that in control group (80.00%) (P<0.05). Conclusion Using nickel-titanium root canal instruments for curved root canal preparation is fast and effective, and it can maintain the shape of the root canal and improve the quality of root canal obturation.
