Introduction: Forensic science have played a key role in human identification. One of the important method of assessing gender isarch length and arch width, palatal rugae pattern and measurement of facial height. Knowledge of dental arch widths in a population plays a key role in orthodontics, Prosthodontics and Oral Surgery.
Aim: The aim of this study was to investigate the maxillary arch width and length in 200 medical and dental students of Davangere.
Materials and Methods: A total of 200 students, 100 males and 100 females, in the age group of 17-23 years were included in the study. The arch length and arch width measurements were performed on maxillary casts using digital Vernier Caliper of 0.01 calibrations. Two-sample t-test and Chi-Square tests were used for comparison of means and relationship between the attributes.
Results: The arch width were significantly greater in males with p value of P<0.001 which is highly significant in our study. The arch length were greater in males than those of the females at all dimensions, which were found to be statistically significant.
Conclusion: The maxillary arch length and arch width can be used as a method in differentiating gender between human population.
