Cervical external root resorption: 3-year follow-up of a case

概要

Cervical external root resorption can be present in natural teeth, involving one or more teeth in the same patient. The incidence of these lesions appears random and the etiology remains unclear. Cervical external root resorption has been considered a difficult clinical situation, and its diagnosis and treatment of the defect challenging. The present report describes a case of multiple external cervical resorption lesions involving four teeth, including the history, and the clinical and radiographic findings. The treatment included surgical intervention and restoration of the defect without sacrificing the pulp. A 3-year re-evaluation of the case confirmed a stable, uneventful clinical recovery. (J.
