Mesiodistal Crown Size in Relation to the Risk and Severity of Malocclusion
… as one factor. Prior studies show that mesiodistally larger teeth increase the risk of malocclusion. The present report extends our understanding by testing for graded responses between crown size and the extent of dental malocclusion. Maximum mesiodistal crown dimensions of all 14 …

Influence of Tooth Crown Size on Malocclusion
… still is no consensus. Some have found that the mesiodistal widths of the mandibular incisor teeth are significantly larger in subjects with anterior crowding, while others have been unable to support this conclusion. Study designs often have been confounded by combining the sexes, which confuses …

Adult age-at-death estimation using the pulp/tooth area ratio (PAR) method: a South African validation study using periapical radiography and stereomicroscopy
… methodological approaches for the method: mesiodistal radiographs, stereomicroscopic tooth section images and PARs excluding the enamel area. To maximise sample size, only maxillary canines were considered, which demonstrate several research advantages (e.g. relatively long functional …

Maxillary Incisor Crown Form and Crowding in Adolescent Orthodontic Patients
<p>Dental crowding occurs when the mesiodistal tooth crown widths exceed the space available in the dental arch for proper alignment. Previous research dealing with this common orthodontic problem has measured mesiodistal (MD) tooth widths or <em>clinical</em> tooth height-to-width ratios from …

A Radiographic Analysis of Variance in Lower Incisor Enamel Thickness
… using dental study models and computer software. Mesiodistal incisor width and mesial and distal enamel thicknesses were measured. Lateral incisors were determined to be wider than central incisors and distal enamel thicknesses were larger than mesial enamel thicknesses on average. The African …

Comparison of Maxillary Anterior Teeth Width to Facial Dimensions among Three Races
… if there is a relationship between the mesiodistal dimensions of the six maxillary anterior teeth and the following facial dimensions: bizygomatic width, interpupillary distance, intercanthal distance, interalar width and intercommissural width among the three different races (Asian, …

The use of permanent maxillary and mandibular canines in sex and age determination in a South African sample
… sex from unknown remains. For this purpose the mesiodistal and buccolingual crown diameters and the maxillary/mandibular canine index were used. Secondly, the Lamendin technique of age estimation was tested and adapted to a South African sample. Therefore, this study aimed to assess the …

Analysis of Bolton's tooth size discrepancy for a referred UK population
… ratio. In total 360 dental casts were used. Mesiodistal tooth dimensions were measured from right first molar to left first molar in the maxillary and mandibular arches. Measurements were taken using HATS digital callipers accurate to 0.1mm. Anterior and overall Bolton discrepancies were …

Subclinical Phenotypes and Genotypes in Parents of Children with Non-Syndromic Cleft of Lip and/or Palate
… between the parents and controls (p<0.05).The mesiodistal dimension of the crown of the lower left second premolar showed a statistically significant (p<0.05) association with SNP rs6657063 in the ARHGAP29 gene when the parental-control group factor was included in the analysis.The symmetrical …

HUMAN PREMOLAR CROWN SIZES ARE VARIABLE EVEN IN THE SAME MOUTH, WITH LOW TO HIGH POSITIVE CROWN SIZE CORRELATIONS AMONG PREMOLARS AND ALL MOLARS.
… initiating teeth. Material and Methods: Maximum mesiodistal lengths of P3, P4, M1, M2, and M3 crowns were measured from retrospective Cone Beam Computed Tomography scans of 91 dental patients (54 female, 37 male) aged 13-23 years using Horos software. Results: Using SPSS, a frequency analysis …
