Taurodontism in primary molars: A case report

Abstract

Taurodontism is a development disorder involving large pulp chambers with the furcal areas located closer to the root apex. The crowns of teeth associated with taurodontism appear normal and its distinguishing features are present below the cementoenamel junction. This makes the radiographic evaluation crucial for its diagnosis. Taurodontism is more commonly found in permanent teeth than in deciduous teeth. Taurodontism occurs mostly as a lone anomaly. Still, it is associated with certain syndromes including Down’s syndrome (Trisomy 21), Klinefelter’s syndrome, and a few medical conditions such as hypophosphatasia. From the perspective of endodontics, taurodontism demands greater efforts for root canal therapies than for a tooth with a normal pulp chamber. The reason is larger pulp chambers that pose obturation errors in the tooth and increase failure percentage. This paper discusses taurodontism associated with primary molars in a 4-year-old dental patient.
