Endodontic treatment in primary molars with taurodontism.

ABSTRACT

Dental morphological traits are of particular importance in the study of phylogenetic relationships and population affinities. One of the most important abnormalities in tooth morphology is Taurodontism. Taurodontism can be defined as a change in tooth shape caused by the failure of Hertwig’s epithelial sheath diaphragm to invaginate at the proper horizontal level. An enlarged pulp chamber, apical displacement of the pulpal floor, and no constriction at the level of the cementoenamel junction are the characteristic features. Although permanent molar teeth are most commonly affected, this change is very rarely seen in primary dentition. Taurodontism has a very low incidence in primary dentition and very few cases have been reported in the literature. Endodontic treatment of a taurodont tooth is challenging, because it requires special care in handling and identifying the canal obliteration and configuration and the potential for additional root canal systems. This paper highlights a case report of taurodontism in primary molars of a five year old male child with endodontic treatment.
