牙周牙髓联合治疗在第一磨牙牙周脓肿病例中的疗效

目的　探讨牙周牙髓联合治疗在牙周脓肿治疗中的疗效。方法　总结1年内收治的反复牙周脓肿发作2次以上的患牙62例，随机分成3组，A组急性期后行严密根管治疗；B组性行常规牙周治疗，辅以牙周袋内注射派丽奥软膏；C组行常规牙周治疗，牙周袋内注射派丽奥，同时开髓扩根、消毒、严密根管充填后调〖HT5”，7”SS〗牙〖KG-*3〗合。结果　经1年随访，无失访，A组有效率为35.0%，B组有效率为40.9%，C组有效率达75.0%。经卡方检验，C组和其他两组有效率有显著性差异。结论　反复发作的牙周脓肿仅进行单纯的牙周治疗或根管治疗是不够的，必须通过牙周和牙髓联合治疗才能解决反复发作的牙周脓肿问题。
