Abstract : Invasive cervical resorption (ICR) is a type of external inflammatory root resorption. A 30-year-old patient showed, on intraoral radiograph and cone beam computed tomography, ICR of the upper-right central incisor caused by walking bleach. The tooth had a fistula, and showed draining not only from the fistula but also into a root canal. After root canal re-treatment and obturation, the ICR lesion in the pulp chamber was curetted with Nd:YAG laser, then mineral trioxide aggregate was used to fill the resorptive defect. Subsequently, the pulp chamber was restored with composite resin. Radiographs at 2, 4 and 6 months showed the suppression of resorption and endodontic success. Clinically, the tooth was asymptomatic, and no periodontal pocket was found at each point.
