摘　　要：目的:探讨原发性牙根纵裂的病因和诊断方法。方法:报告5例原发性牙根纵裂患者资料,并结合文献对原发性牙根纵裂的病因、诊断方法进行回顾性分析。结果:原发性牙根纵裂以磨牙为主。牙根发育缺陷、解剖因素、牙合创伤、牙周炎等因素是导致原发性牙根纵裂的主要因素;根管长度定位仪、X线片、CBCT的应用及牙周探查可以提高诊断的正确率。结论:牙根纵裂的发生存在易感因素,临床表现复杂多样,临床医师应加强对牙根纵裂的认识,做到早发现、早诊断、早治疗。Objective:To investigate the etiology and diagnosis of primary vertical root fracture.Methods:Five cases diagnosed as primary vertical root fracture were reported and the relevant literatures of etiology and diagnosis were reviewed.Result:Root hypoplasia,anatomical factors,occlusal trauma,and periodontitis were the main factors leading to primary vertical root fracture.The application of root apex locator,X-ray,CBCT,and the periodontal exploration could improve the accuracy of diagnosis.Conclusion:There are some predisposed factors in the occurrence of primary vertical root fracture,and the clinical manifestations are complex and diverse.Clinicians should improve the understanding of primary vertical root fracture to make early diagnosis and treatment.
