The aim of this case report was to present a case of multiple idiopathic apical root resorption which is a rare condition in a 17-year-old adult male. External root resorption of the permanent teeth is a multifactorial process. Well-recognized causes of apical root resorption in permanent teeth include orthodontic therapy, trauma, periapical or periodontal inflammation, tumors, cysts, occlusal stress, impacted teeth, systemic conditions, endocrine imbalances and dietary habits. When none of these causes are present, it is termed idiopathic root resorption which may be either cervical or apical. Multiple idiopathic apical root resorption is a rare condition which is usually detected as an incidental radiographic finding. However, it may cause pain and mobility in severe cases.
本病例报告的目的是呈现一例17岁成年男性发生的多发性特发性根尖吸收病例，这是一种罕见病症。恒牙的牙根外部吸收是一个多因素过程。恒牙根尖吸收公认的原因包括正畸治疗、外伤、根尖或牙周炎症、肿瘤、囊肿、咬合压力、阻生牙、全身状况、内分泌失调和饮食习惯。当不存在这些原因时，就称为特发性牙根吸收，可分为颈部或根尖部。多发性特发性根尖吸收是一种罕见病症，通常是在影像学检查时偶然发现。然而，在严重情况下，它可能会引起疼痛和牙齿松动。
