Aim and objective: To compare arch forms between Mongoloid race and Dravidian race in 11–14-year-old children. Materials and methods: Total 10 subjects from each study group were selected. Impression of both maxillary and mandibular arches were taken of all the subjects. Dental casts were poured. Intercanine measurement can be termed as the distance across two canine cusp tips, and intermolar measurement can be termed as the distance across two mesiobuccal cusp tips. This distance was recorded for maxillary and mandibular casts by making use of digital Vernier caliper. Data were tabulated. Statistical analysis: To note the statistical impact, a Chi-square test was applied. Results: The difference across the two groups was found to be statistically significantly noteworthy (independent t test p < 0.001). Conclusion: Group I (Mongoloid race) showed significantly larger intercanine to intermolar width compared to Dravidian race with wide flaring arches. Clinical significance: The size and forms of dental arches exhibit considerable variability within and among human groups. This research demonstrated that while considering Mongoloid patients, we must make use of prior formed orthodontic wires for ovoid shaped arches in a trivial fraction of patients.
