AIMS To evaluate the reliability of Tanaka and Johnston and Moyer's (75th percentile) mixed dentition prediction methods in Kodava population sample, to formulate regression equations for predicting the mesiodistal widths of unerupted canines and premolars and to construct probability tables for the Kodava population. SETTINGS AND DESIGN Data was obtained from Kodava subjects visiting the cli...

The mixed dentition analysis described by Moyers, and later validated by Tanaka, was performed on 80 American blacks to compare prediction equations between Caucasians and blacks. For the black sample, separate regression formulas were determined for the 39 males and 41 females and the combined black sample. Although sexual dimorphism of tooth size was not a consideration in the Moyers predicti...

STATEMENT OF PROBLEM The die contour can affect the emergence profile of prosthetic restorations. However, little information is available regarding the congruency between a stereolithographic (SLA) die and its corresponding natural tooth. PURPOSE The purpose of this vitro study was to evaluate the shapes of SLA die in comparison with the subgingival contour of a prepared tooth to be restored...

INTRODUCTION Orthodontists assess mesiodistal root angulations before, during, and after orthodontic treatment as an aid in establishing proper root position. Panoramic imaging has been useful for this purpose and is a valuable screening tool in diagnosis and planning treatment of orthodontic patients. Cone-beam computed tomography (CBCT) for imaging of the craniofacial complex creates the oppo...

PURPOSE The purpose of this study was to determine the effect of changes in the horizontal plane angle on the mesiodistal width ratios of the maxillary anterior teeth during the acquisition of frontal view photographs, derive these ratios for Korean adults on the basis of the data obtained, and analyze them using the Golden Proportion as a reference. MATERIALS AND METHODS In experiment I, 30 ...

This study deals with correlations of tooth size in human primary teeth. Traditionally, mesiodistal or buccolingual measurements have been used to express crown size. However, in this study, crown area was used as a reference parameter. Graphic reconstructions of 38 histologically prepared human fetuses with Crown-Rump Length (CRL) between 54 and 280 mm were used to obtain linear and area measu...

abstract : the crown-root fracture is a common tooth injury which compromises the biological width and need proper endodontic and prosthodontic treatment to achieve acceptable clinical outcome. this case report describes clinical management of crown-root fracture in maxillary central incisors which was successfully treated by forceps eruption with 180˚ rotation to restore the biological width. ...

In a recent paper Lavelle ( Dent Res 56:541, 1977) reported both differing magnitudes and patterns of mesiodistal-buccolingual crown-size correlations in 3 human races and in samples of Pan, Pongo, and Gorilla, using 20 males in each case. Others have called attention to differences in crown-size correlations (r) and variances (a2) from similarly small archeological samples (SUAREZ, AmJ Phys An...
