Dens Invaginatus with a Radicular cyst-A Case report

Ens invaginatus is a developmental malformation of teeth. It is a dental anomaly resulting from invagination of the enamel organ into the dental papilla, during odontogenesis. Affected teeth show a deep infolding of enamel and dentine starting from the foramen caecum or even the tip of the cusps and which may extend deep into the root. Teeth most affected are maxillary lateral incisors. The affected teeth radiographically shows an in folding of enamel and dentine which may extend deep into the pulp cavity and into the root and sometimes even reach the root apex. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. The radiographic examination is the most realistic way to diagnose the invagination. Root canal therapy may present severe problems because of complex anatomy of teeth.
