Abstract

In this case report, the treatment of internal root resorption in a 24 years-old male was done by using nonsurgical root canal therapy and the clinical outcome was evaluated. Both the maxillary central incisors were examined clinico-radiographically. On clinical examination, the maxillary incisors were found discolored. Radiographic examination revealed a punched-out radiolucent lesion on the cervical area of pulpal canal of both of the teeth and periradicular radiolucency was also evident. Conservative non-surgical root canal treatment was performed with long term calcium-hydroxide therapy. Following eight months of the treatment, the resorption process was stopped and a calcific bridge was formed at the apex of the roots indicated the evidence of recalcification. Conventional root canal obturation method was implied followed by clinical and radiological evaluation for next two years. DOI: http://dx.doi.org/10.3329/bsmmuj.v5i1.11029 BSMMU J 2012; 5(1):72-75

Highlights

Resorption of root is one of the reasons for loss of the tooth at an early age and it is a major concern in endodontic therapy.[1]
When resorption of permanent teeth is observed clinically, the resorption is usually due to the result of trauma; chronic inflammation of the pulp or periodontal tissues, or both; or induced pressure in the periodontal ligament associated with orthodontic tooth movement, tumors, or tooth eruption.[3]
Radiographic evidence showed no extension of resorption both internal and external [Figure-2(g)] and, the root canal treatment was completed with lateral condensation technique [Figure-3(h)] where zinc oxide eugenol was used as sealer

Summary

Introduction

Resorption of root is one of the reasons for loss of the tooth at an early age and it is a major concern in endodontic therapy.[1]. Pulpal inflammation initiates internal resorption followed by disappearance of the odontoblasts and pre-dentin, and a pulpal invasion of macrophage-like resorbing cells.[4,5] The signs and symptoms of this pathologic condition remain asymptomatic unless it is detected on radiographic screening. It is observed in the cervical region but may occur in all areas of the root canal system.[3] When the resorption occurs in coronal region it is usually appears as pink spot.
