■创伤性牙髓炎和根尖周炎的临床研究

Clinical studies on pulpitis and periapical periodontitis caused by traumatic occlusion

为进一步探讨创伤引起牙髓和根尖周炎的病因、病理及临床诊治情况，作者通过对８９例患者的１００颗此类患牙的病例观察，总结出这类疾病的发病特点和临床表现；提出了创伤性牙髓炎或根尖周炎的诊断名词与诊断指标，并对这些病例进行了２年的追踪观察及疗效分析，提出了综合治疗方案。为这类疾病的临床诊治提供了依据。

cases including 100 teeth with pulpitis and apical periodontitis caused by traumatic occlusion were clinically observed All teeth are caries free,no any dental disease,and no pocket formation But there is a distinct evidence of marked occlusal trauma,such as premature contact and occlusal interference The single root teeth are usually involved When subjected to vitality testing the teeth associated with the periapical lesions sometimes yield positive response(about30%) The result of investigation endodontic treatment demonstrated that the presence of predisposing factors of trauma from occlusion led to decrease of endodontic success.
