The use of MTA in the modern management of teeth affected by dens invaginatus.

Dens invaginatus is a dental anomaly that can result in loss of tooth vitality and the need for root canal treatment. The pulpal morphology of these teeth can be complex which makes successful root canal treatment difficult to achieve. To maintain vitality attempts have been made to prophylactically treat these teeth by sealing the invagination with a variety of materials. This paper describes the use of mineral trioxide aggregate (MTA) in both the prophylactic treatment of teeth with minor invaginations and the incorporation of MTA in the final obturation of non-vital teeth with invaginations with grossly atypical morphology.
