摘　　要：目的:探讨后牙V类洞干髓术的抗冠折疗效。方法:选择68例患牙随机分为干髓组及根管治疗组。6—12个月复查,观察干髓术与根管治疗术的患牙抗折率。结果:后牙V类洞干髓术的抗折率高于根管治疗组,两者间差异有显著性(p<0.05)。结论:后牙V类洞干髓术较根管治疗术抗折率高。Objective：To evaluated the flexural strength of dental pulp for class V cavity in posterior teeth,which were treated either with pulp mummification or root canal therapy.Method： 68 posterior teeth were randomly divided into 2 groups,one group was treated with pulp mummification while the other was treated with root canal therapy.6-12 month later,flexural strength of these teeth were evaluated and compared between the two groups.Result： Flexural strength of dental pulp for class V cavity in posterior teeth treated with pulp mummification was higher than that of those treated with root canal therapy（p〈0.05）.Conclusion： Flexural strength of dental pulp for class V cavity in posterior teeth treated with pulp mummification was better.
