摘要
目的:通过离体牙、人工根管培养实习医生了解并掌握根管治疗的标准程序和方法。方法:选择正畸患者拔除离体牙36颗、牙髓病及牙周病拔除离体牙42颗,人工根管4颗,分组采用常规改良逐步后退法、冠向逐步深入法进行根管处理、预备及充填,观察实习医生根管治疗掌握情况及模拟治疗效果。结果:离体牙采用改良逐步后退法时,前牙根管治疗成功率>前磨牙>磨牙(P<0.05);离体牙磨牙组中,采用冠向逐步深入法成功率高于逐步后退法(P<0.01)。结论:采用人工根管可以直观的辅助实习医生体会弯曲根管的治疗,结合离体牙进行根管治疗训练可以提高加深实习医生对根管解剖结构、不同根管治疗方法的了解,对于实习医生临床前培养有明显效果。
Objective: Teeth in vitro and simulated root canal were used to develop the ability of interns in root canal therapy before their clinical practice.Methods: 36 removed premolars of patients receiving orthodontic treatment,28 removed teeth with pulp diseases or periodontitis and 4 simulated root canals were used for interns to grasp two kinds of root canal treatment techniques as step-back technique and crown-down technique.Results: As treated with step-back technique,the successful rate in anterior teeth was higher than that in premolars and molars(P〈0.05).In molars,the successful rate of crown-down technique was higher than that of step-back technique(P〈0.01).Conclusion: Root canal treatment processed in simulated root canal and teeth in vifro would benefit interns to grasp the technique.
