摘　　要：目的 评价后牙V类洞干髓术的临床疗效。方法 120例患牙随机分为V类洞干髓组及常规(牙合)面洞治疗组。3～5年复查,观察干髓术的成功率和患牙抗折率。结果 V类洞组痊愈率、有效率分别为51.43%、25.71%;常规组分别为53.19%和23.40%,两者比较差异无显著性。V类洞组牙折率为5.91%,而常规组为19.15%,两者间差异有显著性(P<0.05)。结论 V类洞干髓术可提高干髓治疗牙的抗折力。Objective To evaluate the clinical effects of mummification of dental pulp for class V cavity in posterior teeth. Methods 120 teeth were selected and divided randomly into class V cavity group and occlusal cavity group. The mummification of dental pulp was performed in each patient. After a follow-up of 3 - 5 years, the rates of success and resistance were reviewed. Results There was no significant difference in the rates of success between the two groups( P < 0.05) .There was a significant difference in the rates of fracture between the two groups( P < 0.05). The rate of fracture in class V cavity group was lower than that of the occlusal cavity group. Conclusion The mummification of dental pulp for class V cavity could obviously improve the teeth resistance.
