Tooth structure loss is a normal part of the aging process, with generalized predictable patterns. However, when a dentist is faced with an atypical pattern of extensive structural damage, identifying the etiology responsible for the catastrophic collapse of a patient's anterior incisal guidance can be a diagnostic challenge. Clinicians who are presented with plausible medical histories juxtaposed with socially and culturally accepted eating behaviors may clarify an otherwise nebulous clinical presentation. This article presents an unusual case report involving both synergistic and synchronous habitual and culturally adopted eating practices and pica, which resulted in severe tooth abrasion, abfraction, and erosion.
牙齿结构丧失是衰老过程中的正常现象，具有普遍可预测的模式。然而，当牙医面对广泛结构损伤的非典型模式时，确定导致患者前牙切导灾难性崩溃的病因可能是一项诊断挑战。面对看似合理的病史与社会和文化上可接受的饮食行为并存的临床医生，可能会澄清原本模糊不清的临床表现。本文介绍了一个不寻常的病例报告，该病例涉及协同和同步的习惯性及文化上形成的饮食行为与异食癖，导致了严重的牙齿磨损、楔状缺损和侵蚀。
