DENS-INVAGINATUS - REVIEW OF FORMATION AND MORPHOLOGY WITH 2 CASE-REPORTS

Dens invaginatus manifests itself with an aberrant morphologic charact er because of altered patterns of tooth formation. Presented in this a rticle are 2 cases of dens invaginatus in maxillary lateral incisors t hat were successfully treated nonsurgically. In the first case, a circ ular main canal was clearly observed surrounding the invaginated canal . The involved tooth in the second case responded to electric pulp tes ting, though a periapical radiolucency was evident; root canal treatme nt of the invaginated canal failed to resolve the pathosis. Debridemen t of both the main canal and the invaginated canal produced resolution . The complex morphologic nature of these root canal systems and the c lose relationship between the invaginated and main canals is demonstra ted and discussed.
