Idiopathic cervical resorption: a diagnostic dilemma.

Idiopathic cervical resorption is a rare form of external resorption, usually with no external signs, and can be misdiagnosed as dental caries or other types of tooth resorption. Here we report a case in which, during routine radiography, an asymptomatic lower right molar presented with a radiolucency at the cervical region, with no obvious aetiologic factor identified. CLINICAL RELEVANCE: This paper emphasizes the aetiopathogenesis and differential diagnosis of this rare and asymptomatic form of pathologic resorption, which can be encountered in dental practice.
