The aim of this case report was to present the non-surgical root canal treatment of the geminated maxillary anterior lateral incisor tooth. A 50-year-old female patient was referred for endodontic treatment of her maxillary right lateral incisor. In the clinical examination, a large crown was observed in the right maxillary incisor region when compared with the left maxillary lateral incisor. T...

Introduction: Since crown lengthening surgery could be accompanied by stress, pain and discomfort, knowledge about its predisposing factors could reduce the demands for such surgery.The aim of this study was to identify the most important indications of crown lengthening surgery in order to present new ideas to clinicians on how to reduce the need for this surgery. Methods: This cross-sectio...

3 Introduction noticed in whale's tooth by Ploquet in 1794. Salter first described this anatomical anomaly Dens invaginatus is a dental anomaly as “a tooth within tooth” in 1855, and was the which results from invagination of enamel first person who described dens invaginatus in organ into dental papilla, beginning at the 3 ,4 human tooth in 1856. Clinically, a crown and sometimes extending int...

A method of measuring the volume of the human dental pulp cavity is described. The crown of an extracted tooth is divided from its root. .After cleaning the pulp cavity, it is filled with an elastomer, and the fractured tooth surfaces repositioned before the elastomer sets. The tooth is corroded in acid to release the elastomer which is then weighed, and its volume calculated. The method has be...

The presence of a supernumerary tooth in the nose is an unusual phenomenon and a rare form of ectopic tooth eruption in the maxillofacial region. In this case, the patient was referred to the hospital with the complaint of severe headache. In the endoscopic examination, the supernumerary tooth crown was not covered with mucosa or granulation tissue. In the present study, the clinical and radiol...

BACKGROUND Molecular clock estimates of crown strepsirhine origins generally advocate an ancient antiquity for Malagasy lemuriforms and Afro-Asian lorisiforms, near the onset of the Tertiary but most often extending back to the Late Cretaceous. Despite their inferred early origin, the subsequent evolutionary histories of both groups (except for the Malagasy aye-aye lineage) exhibit a vacuum of ...

Most archaeological and fossil teeth are heavily worn, and this greatly limits the usefulness of tooth crown diameter measurements, as they are usually defined at the widest points of the crown. There are alternatives, particularly measurements at the cervix of the tooth, where the crown joints the root, and measurements along a diagonal axis in molars, that are much less affected by wear. Thes...

We propose a method for restoring the surface of a tooth crown so that the pose and anatomical features of the tooth will work well for chewing. The system of teeth has been modeled with a 3D statistical multi-object shape model build from 3D scans of dental cast models. The restoration is carried out using the shape model statistics in a Bayesian framework to calculate the most probable tooth ...
