title: Type II canal configuration and Type I Dens invaginatus.
abstract: The prevalent notion about maxillary central incisor with normal external morphology is a tooth with single root and root canal. A case in which all four maxillary incisors were having Type II canal configurations (Vertucci's classification) is reported, in addition, the lateral incisors revealed dens invaginatus with a Type I pattern as suggested by Ohler's classification and a large periapical lesion was seen in relation to the right lateral incisor. The diagnosis was confirmed with the aid of spiral computed tomography (CT) and canals obturated. Nonsurgical healing of the lesion was assessed by reviewing the case at prefixed intervals of time.
