Abstract:

The simultaneous existence of pulpal problems and inflammatory periodontal disease can complicate diagnosis and treatment planning. Endodontic and periodontal lesions result from the close interrelationship of pulp tissue and the periodontium. The major pathways of communication between the two types of tissue are the apical foramina，lateral and accessory canals，and dentinal tubules. The differential diagnosis of endodontic and periodontal lesions is not always straightforward and requires clinical data accumulation from a number of diagnostic tests to obtain a correct diagnosis. When examining and treating the combined or individual lesion in endodontics and periodontics，the clinician must bear in mind that successful treatment depends on a correct diagnosis. Lesions with combined causes will require both endodontic and periodontal therapy，and endodontic therapy should usually be completed first.

Key words: pulpal disease, periodontal disease, combined periodontic-endodontic lesions

摘要：

牙髓病与牙周病的鉴别诊断通常不是简单明了的，患牙同时罹患牙髓病损和牙周病损无疑大大增加疾病的诊断难度，需要通过诊断性检查收集大量临床数据来获得正确的诊断。当检查和治疗牙周牙髓联合病变或单个病变时，必须牢记成功的治疗基于正确的诊断。
