Many morphometric studies show a sexual dimorphism in human teeth. We wanted to know whether it is possible to determine the sex of an individual if only the anterior teeth are visible. Fifty intraoral photographs showing the front tooth region of female and male individuals (age: from 7 to 75 years) were randomly arranged in actual size on a questionnaire. The lip region was covered in each case. Besides "female" and "male", one was also able to check "?" if undecided. The questionnaires were… 

Application of dental morphological characteristics for medical-legal identification: sexual diagnosis in a portuguese population

A gender classification model using significant different traits between both sexes of the teeth 13, 27 and 43 was developed, and it proved to have a reasonable gender classification reliability although with a significant probability of misclassification.

A gender classification model using significant different traits between both sexes of the teeth 13, 27 and 43 proved to have a reasonable gender classification reliability and has proven to be the most dimorphic among the Portuguese population.

A Quantitative Analysis of Lip Aesthetics: The Influence of Gender and Aging

This study provides novel thresholds that may contribute to the assessment of adequate reconstruction of lips in aesthetic surgery as well as verifying the metrical characteristics of female and male lips.

A new approach to sex estimation using the mandibular canine index

Although statistically significant sexual dimorphism was observed in both the mesiodistal dimension and the mandibular canine arch width, the MCI showed a low accuracy in sex classification, and this reinforces the idea that it may not be particularly useful in sex prediction.

Sex estimation using the mandibular canine index components

The results suggest that MD43 should be used instead of MCI for sex estimation, as it exhibited the same accuracy as the logistic model based solely on MD43 (85.8%).

Tooth size and arch dimensions in a hypodontia patient group

Tail size and arch dimensions are reduced in hypodontia patients with no racial differences between White British and South Asian subjects and these factors should be carefully considered in the treatment planning process to ensure an optimal outcome for the patient.

Perception of dental anatomy among dental students, dental practitioners, and dental academicians: A questionnaire-based cross-sectional study

There was no significant difference in the opinion about dental anatomy between the undergraduate dental students and the professionals except for their opinion regarding the course curriculum.

A systematic review of odontological sex estimation methods.

Biochemical analysis of teeth proved to be the most accurate method, but in forensic practice, a need to select the most appropriate evidence based odontological sex estimation method exists.

Mathematical Tooth Proportions: A Systematic Review.

Although the golden percentage may be a good starting point if the percentages are adjusted on a case-to-case basis, generalized esthetic ideals cannot be determined by a mathematical formula and are open to interpretation by both the clinician and the patient.

If sexual dimorphism in tooth-crown size is as pronounced in the de- ciduous dentition as it is in the permanent dentition, then it may be possible to correctly assess the sex of children as young as two years, according to discriminant analysis.

The averages of both the deciduous and permanent teeth show that female individuals possess altogether teeth of smaller dimensions, and the presumptive sex determination for this investigation could be achieved because of specific burial rites that characterize the Unterwölbling culture south of the Danube.

The correlation of sexual dimorphism in tooth size and arch form.

The results do not offer a safe conclusion when comparing the sum of the mesiodistal distances of the 6 anterior teeth to the arch form, and the female subjects in this sample had both smaller teeth and smaller maxillary and mandibular arch dimensions.

Odontometric variation among American black, European, and Mongoloid populations.

E Easily obtained area and shape parameters derived from dental radiographs proved useful as discriminators among racial groups and the sexes and lend further support to the hypothesis of an African origin of modern humans.

Prevalence, association, and sexual dimorphism of Carabelli's molar and shovel incisor traits amongst Jordanian population.

The Jordanian Population had comparatively high prevalence of Carabelli's molar and shovel incisor traits and there was a positive association between Carabellis' trait on maxillary first molars and shovel trait in males.

Sexual Dimorphism in the Emergence of the Deciduous Teeth

Results of the present study, combined with those of previous research, suggest that sexual dimorphism in the emergence of the deciduous teeth could be mediated through ethnic factors.

Dental Age in Southwest Germany A Radiographic Study

The fact that dental age distribution in Southwest Germany is not significantly correlated to that of a French-Canadian collective underlines Demirjian's demand for regional standards of dental development to be calculated using his score system.
