A Review on Internal Resorption

Abstract

Tooth Resorption is classified majorly into internal and external resorption as given by Andreason. The lesion puts the dentist in a predicament for treatment of the lesion, as it is often discovered accidentally, decreasing the prognosis as it is found later. Since the lesion usually affects the esthetically important region, it places the dentist in a quandary on what to do. Various factors affecting the pathophysiology of the lesion are the inflammatory process, stimulation of clastic cells. The etiology for the lesion is trauma in the majority of the cases. However, it may also be caused by excessive heat production during cavity preparation and in untreated carious lesions. Clinically it appears to be typically asymptomatic, although when it is actively progressing, the lesion shows symptoms of pulpitis as it mainly occurs due to chronic inflammation of the pulp. Histopathologically the lesion shows connective tissue of pulp which is inflamed and infiltrated by neutrophils, lymphocytes, plasma cells, and macrophages. The granulation tissue dominates the lesion. Radiographically the lesion occurs as oval to round radiolucency in the crown. The treatment performed is root canal treatment (RCT), as terminating the progressing resorptive process is the goal, and by doing so, further damage to the tooth can be prevented. Internal resorption will result in loss of tooth unless it is treated.
