Correct answer: E — Buccal/labial surface at the CEJ
Cervical abrasion lesions occur most commonly on the buccal/labial surface at the cervico-enamel junction (CEJ), typically presenting as V-shaped or wedge-shaped notches. They are caused by overzealous horizontal tooth brushing with abrasive toothpaste. The maxillary premolars and canines (prominent in the arch) are most frequently affected. Treatment involves modifying brushing technique, using a soft-bristled brush, and restoring the defect with composite or GIC if sensitivity or pulp proximity is a concern.
