The existence of sexual dimorphism in the size of the permanent teeth is a well-known attribute of primates, particularly so for the canine teeth, in which the magnitude of the sex difference in the mesiodistal crown diameter may equal 50 percent or even more. However, little attention has been given until recently to the extent of sexual dimorphism in the remaining teeth of various primates and to variations in the magnitude of sexual dimorphism and the patterning of sexual dimorphism in…

Dental crown size and sex hormone concentrations: another look at the development of sexual dimorphism.
TLDR
The results suggest that gross changes in sex hormone concentrations during development are not related to population-wide patterns of sexual dimorphism among the tooth types of human permanent tooth classes, as recent studies indicate.
Relationship of sexual dimorphism in canine size and body size to social, behavioral, and ecological correlates in anthropoid primates
TLDR
The degree of canine size dimorphism is closely related to the amount of male intrasexual selection in a given mating system; and the degree of body sizeDimorphism may be modified by selection pressure from factors such as habitat, diet, foraging behavior, antipredator behavior, locomotory behavior, and female preference.
The Relative Sexual Dimorphism of Human Incisor Crown and Root Dimensions
TLDR
Measureting the four incisor tooth types from standardized periapical radiographs in a sample of living American white adolescents found no added discriminatory power in the crown sizes once root dimensions have been accounted for, though the addition of data from other tooth types might improve discrimination somewhat.

Sexual dimorphism of root length on a Greek population sample.
Sexual dimorphism of the dental tissues in human permanent mandibular canines and third premolars.
TLDR
Results suggest that relative area measures of crown tissues are more predictable measures of sexual dimorphism than absolute measures, and tissue proportions may remain constant despite intrasex variation in overall tooth crown size.
Sexually dimorphic mandibular morphology in the first few years of life.
TLDR
The results of this study indicate that it is possible to determine the sex of very young mandibles and the new sexually dimorphic morphologic configurations introduced here have demonstrated repeatable discrimination with the highest level of accuracy reported and tested for this age group.
Canine crown morphology and sexual dimorphism in the Pan paniscus
TLDR
Compared with other hominoids, the Pan paniscus canine revealed a definite sexual dimorphism in size, shape and structure, which may reflect an intimate social structure of the multi-male unit.

Canine “Field” in Sexual Dimorphism of Tooth Size
TLDR
This work has shown that sexual dimorphism in the size of permanent teeth is usually greatest for the canine tooth in Hylobates agilis and Homo sapiens and by nearly as much as 80 per cent in Papio anubis.
Sexual Dimorphism in the Buccolingual Tooth Diameter
TLDR
While sex clearly affects tooth size throughout the dentition, dimorphism is particularly large for baby teeth, and reduction in tooth number has been related to reduced size and morphological complexity of the remaining teeth.
On the Sexual Differences in the Dimensions of the Human Teeth
TLDR
It might be surmized that the larger canine of the male represents the phylogenetical trace of the striking sexual difference prevailing in the animal kingdom.
Sex Difference in Tooth Size
TLDR
In connection with continuing studies on X-chromosomal determination of intraindividual tooth-size variability, the sex difference in absolute tooth size was concerned with, using mesiodistal crown diameters of 243 middle-class, Ohio, white children, measured by one of us throughout.
Metric and taxonomic variations in the dentitions of two Asian cercopithecoid species: Macaca mulatta and Macaca speciosa.
TLDR
The discriminant function analysis reveals that the two species may be distinguished by tooth dimensions alone except in the dimensional range where over-lapping is expected.

TLDR
The fauna is characterized by the relative abundance of orang-utan (more than 3000 teeth: Hooijer, 1948), and contains no extinct species.
