Orangutans are believed to have close biological affinities to humans. Teeth being the hardest tissue provide useful information on primate evolution. Furthermore, knowledge of the pulp chamber and root canal morphology is important for dental treatment. A female Bornean orangutan and a Sumatran male orangutan skull were available for this study. Both of their dentitions, comprising 50 teeth, w...

INTRODUCTION Sound knowledge of the external and internal morphology of the different teeth groups is essential to ensure a successful outcome of root canal treatment. The aims of this study were to review the available literature with respect to the root and root canal morphology of maxillary first premolars and discuss the clinical considerations of this morphology on the various dental proce...

Teeth morphology has been widely used in taxonomic, biological and fossil teeth studies of Chondrichthyes. Herein, dental abnormalities in Amblyraja doellojuradoi are described. Almost 10% of 182 specimens sampled presented any of these types of dental anomalies: (1) an additional incomplete tooth row between two complete rows, (2) an increasing tooth base size and division of its cusps until t...

X-ray absorption microtomography, a high resolution variant of medical “CT”, and synchrotron x-ray phase contrast imaging reveal the distribution of mineral within teeth of the sea urchin Lytechinus variegatus. Data from these imaging modalities on intact teeth are compared with histochemically stained thin sections observed with transmission optical microscopy. Because these teeth grow continu...

This paper reports the management of two clinical cases, in which the upper right central incisor was fused with a supernumerary tooth and the upper left central incisor was macrodontic. A radiographic examination revealed that the fused teeth had two separate roots. Hemisectioning of the fused teeth was performed, the supernumerary portion was extracted and the remaining part was reshaped to r...

OBJECTIVE The objectives of the present study were to investigate the prevalence and characteristics of supernumerary teeth and evaluate the associated pathologies and treatment protocol in a Turkish patient population. STUDY DESIGN A retrospective study was performed using full-mouth periapical and panoramic radiographs of 3491 patients (2146 females and 1345 males) ranging in age from 12 to...

The present case report highlights about management of taurodontism which is a developmental anomaly characterized by the lack of constriction at the level of the cementoenamel junction, vertically elongated pulp chambers and apical displacement of the pulpal floor. Permanent molar teeth are commonly affected teeth. Its morphology might hamper the location of orifices and can create difficultie...
