Introduction: To investigate crown height for sexual dimorphism and its relation to arch length, arch perimeter and arch width (Inter canine, Inter premolar, Intermolar) groups of maxilla and mandible.

Material and Methods: Cross sectional study was done the data were collected from 128 subjects (64 males and 64 females with mean age 19.4 ± 1.9 SD). Arch perimeter, arch length, crown height, and width of arch of both maxilla and mandible were acquired by digital calliper (Mitutoyo, Japan). Total variables measured were 4,855. Sex differences in the crown height were explored. Analysis of variance (ANOVA) was applied for evaluating the differences if any between arch perimeter, arch length, and arch width groups.

Results: Noteworthy larger mean values in males than females for crown height (p ≤ 0.05) for maxillary as well mandibular arches. No substantial differences were observed in average vs. large, average vs. small, large vs. small groups of arch length, arch perimeter and arch width (Inter canine, Inter premolar, Intermolar) groups (p ≤ 0.05) for both maxillary and mandibular arches.

Conclusions: Our results specified sexual disparities in the height of crown. Crown height has no substantial relation to different arch perimeter, arch length, and arch width groups of both maxilla and mandible. Hence it might be useful for orthodontic case investigation and treatment of various malocclusion groups.
