根管治疗与冠修复同步对隐裂牙牙髓病患者咀嚼功能、生活质量的影响

Effect of synchronous root canal therapy and crown repair on chewing function and quality of life in cracked dental pulp disease

目的观察根管治疗、冠修复在隐裂牙牙髓病中应用效果。方法120例隐裂牙牙髓病患者随机分为对照组与观察组。对照组先行根管治疗,再行冠修复治疗;观察组给予根管治疗与冠修复同步治疗。比较两组治疗效果、咀嚼功能、治疗1周后疼痛率及治疗后8周生活质量。结果观察组总有效率、咬合力、咀嚼效率、生活质量高于对照组(P<0.05),而牙龈指数、出血指数、松动度、治疗1周后疼痛率低于对照组(P<0.05)结论根管治疗与冠修复同步治疗可提高隐裂牙牙髓病患者疗效,改善咀嚼功能、生活质量。

Objective To observe the clinical effect of root canal therapy and crown repair in cracked dental pulp disease(CDPD).Methods A total of 120 CDPD patients were randomly treated with root canal therapy followed by crown repair(control group)or synchronous root canal therapy and crown repair(observation group).Clinical efficacy,chewing function,1-week pain and 8-week quality of life(QOL)were compared between two groups.Results Compared with control group,overall efficacy,bite force,chewing efficiency,and QOL were higher(P<0.05),while gum index,bleeding index,looseness,and 1-week pain were lower(P<0.05)in observation group.Conclusion Synchronous root canal therapy and crown repair can improve clinical efficacy,chewing function and QOL in CDPD patients.
