Invasive cervical resorption: clinical and radiological diagnosis and treatment of 3 cases

Abstract

Invasive cervical resorption is a relatively uncommon form of external root resorption. Etiologic factors include trauma, orthodontic treatment, intracoronal bleaching, and inflammation, but invasive cervical resorption is often idiopathic. There may be no external signs of this disorder, and the resorptive lesion is often detected by routine radiographic examination. This article describes the clinical and radiological diagnoses and treatment modalities of invasive cervical resorption in 3 patients. Two of the 3 cases were incidental radiographic findings and the teeth concerned were symptom free. One case was symptomatic due to periodontal infection. Computed tomography (CT) evaluation was performed in the 2 symptom-free patients. Thus, exact size and localization of the resorptive lesions were obtained. In 2 cases, root canal treatment was performed, and in the other case the resorptive defect was sealed with mineral trioxide aggregate.
