Management of external cervical resorption using mineral trioxide aggregate

Abstract

External cervical resorption (ECR) is a relatively rare form of external root resorption, which may occur in any tooth in the permanent dentition. The etiology is usually obscure. It is characterized by its cervical location and the invasive nature; this resorptive process leads to the progressive and usually destructive loss of the tooth structure. It is often misdiagnosed, leading to improper treatment or unnecessary loss of the tooth. The article describes a case report of the ECR and its management. The salient features were a sizeable resorptive defect and localized fibrous growth located on the cervico-palatal aspect of the maxillary right central incisor. Treatment included root canal treatment, surgical exploration, and restoration of the defect with mineral trioxide aggregate. Proper diagnosis and the appropriate treatment is the key to a successful outcome in the management of ECR.
