Management of internal resorption with mineral trioxide aggregate: a case report.
Pak Armed Forces Med J Jan ;59(2):189-90.

Tooth resorption is a condition associated with either a physiological or a pathological process resulting in loss of dentin, cementum or bone [1, 2]. The diagnosis of resorption into internal and external resorption is usually based on clinico-radiographic finding, while internal resorption can be further classified into internal inflammatory resorption and root canal replacement resorption on the basis of histopathologic results. Internal inflammatory resorption is comparatively more destructive and results in loss of tooth structure without the deposition of any hard tissue. It is most commonly found in the cervical region [1], and clinically presents asymptomatically. Usually the coronal pulp is necrotic and apical pulp is vital. The resorptive defect creates a clinically obvious pinkish color in the tooth crown because of the highly vascular resorptive tissue which becomes visible through the thin residual enamel [1, 2]. Radio graphically the lesion presents as a circumscribed; oval enlargement which is continuous with the root canal wall and ultimately leads to distortion of the canal outline [3]
