External cervical resorption is often silent, yet treatment planning becomes complex when a subgingival lesion is close to the root canal space. In such cases, the clinical view may underestimate the defect. CBCT provides the information required to define the portal of entry, height, circumferential spread and relationship with the canal.
This case report presents the management of an asymptomatic tooth 44 in a 62-year-old female patient, diagnosed with a Patel 2A external cervical resorption lesion. Treatment combined surgical exposure, removal of fibrovascular resorptive tissue, adhesive repair of the defect and single-visit root canal treatment after identification of a second lingual canal.
