23 In case of AI, the pathology affects all dentition, the family history is usually involved and the radiographic examination can reveal taurodont teeth.
Hyperdontia is found to be more common in patients with cleft lip and palate.36 A taurodont usually presents with elongated pulp chambers having greater apicoocclusal height and lacking constriction at cementoenamel junction level.38 It shows wide variation in the size and shape of the pulp chamber, making root canal therapy a challenge.
In the oral cavity, a taurodont appears as a normal tooth.
(13) Clinically, the taurodont crown has normal form, structure, colour and texture, so, it can only be diagnosed by radiographs.
The present case describes successful completion of endodontic treatment of a taurodont maxillary first molar, which seemed impossible to perform with conventional techniques.
Most likely, the prominent pulp horns that project under the cusps of the taurodont tooth cause the enlargement in spite of the normal size of the dentine.
Endodontic treatment of a taurodont tooth is challenging and requires special handling because of the proximity and apical displacement of the roots It has been reported in permanent and deciduous teeth, in premolars and molars and are associated with certain syndromes, particularly in those involving an ectodermal defect.
Taurodontism has been reported in association with certain syndromes and some genetic defects like hy- podontia, Mohr syndrome, Down syndrome, Van der Woude's syndrome and cleft lip/palate, but its true significance is still obscure.18,19 The reported preva- lence of taurodont molars and premolars ranges from 0.25[?]11.3% (Table 1) which means that a endodontitist seeing 100 patients a week could expect an average of 5 patients a week to show features of taurodontism.
Developmental Talon cusp; taurodont teeth; molar incisor hypoplasia; amelogenesis imperfecta; cleft lip and palate.
Endodontic management of a taurodont tooth has been described as complex and challenging.
Its distinguishing features cannot be recognized clinically.4,6 The diagnosis of taurodontism is usually a subjective determination made from diagnostic radio- graphs.7 The radiographic characteristics of taurodont tooth are (i) extension of the rectangular pulp chamber into the elongated body of the tooth, (ii) shortened roots and root canals, and (iii) location of furcation near the root apices, despite a normal crown size.4,6
