Management of a rare case of class II double dens invaginatus in a maxillary lateral incisor

Abstract

Introduction: Dens invaginatus is a developmental malformation resulting from invagination of tooth crown or root before calcification and during odontogenesis. It is a critical condition for which endodontic treatment is essential, as it frequently presents a complex internal anatomy. Double dens invaginatus is an extremely rare condition. Objective: The present study reports a rare

Successful management of a type II Dens invaginatus with an open apex and a large periapical lesion. A case report of a permanent maxillary canine

“…Late identification of the invagination may lead to the invaginated pulp necrosis and periapical lesions, at early ages after invaginated tooth eruption, subsequent to main pulp contamination through the invagination space. These conditions are reported to be the main circumstance of dens Invaginatus discovery [12,[25][26][27][28][29][30]. In the current case, the CBCT showed an invagination which extented into the root of the left maxillary canine which was categorized as Oehler's type II dens invaginatus.…”

“…The morphological complexity of the present type II dens invaginatus case posed serious clinical challenges [12].…”

MAXILLOFACIAL RADIOLOGY Double type III dens invaginatus

“…5 Teeth demonstrating double dens invaginatus on a single tooth have also been reported, but these usually present with type I or II confi gurations. [8][9][10][11][12] Four cases of a double dens invaginatus (type III with type II) have been reported in the literature, two of which were successfully treated with non-surgical endodontic therapy. [13][14][15][16] A single tooth affected by a triple type II dens invaginatus has been reported, but subsequent radiographic features resemble a compound odontoma.…”
