“…Furthermore, arch dimensions are also larger in males than in females (10). Similarly, few more studies in other populations which measured linear absolute dimension found that dental arch dimensions were larger in males than in females (11)(12)(13)(14)(15). These outcomes showed potential of using arch size variables for gender prediction which require further investigations of their applicability in forensic services.…”

Introduction: In circumstances where the ante mortem list is unknown, gender determination would exclude one-half of the population, aid in a more precise search of the ante mortem records. This study aims to formulate gender prediction models in the Pakhtun Pakistani population using digital dental arch dimensions. Methods: Data collection and analysis of the dental casts were conducted on 128 subjects, 64 males and 64 females from the Pakistani population. The mean age of the subjects was 19.2 years old. Several linear dental arch dimensions were measured and recorded for both upper and lower arches. Results: It was found that gender differences in linear arch dimensions were statistically significant for both males and females (p<0.05); in which the arch dimensions for the males were larger than the arch dimensions for the females. Stepwise discriminant function analysis found that the highest discriminant power of the variables was present within the inter-second premolar width for the upper arch and inter-molar width for the lower arch. These variables significantly contributed to gender variance. Moreover, the prediction of 67.2% of original grouped cases for the upper arch and 66.4% of cross-validated group cases was correct. Similarly, the correct prediction was made on 64.8% of original grouped cases for the lower arch and 64.1% of cross-validated group cases. Conclusion: The dental arch dimensions were larger among the males compared to the females. Prediction models obtained in this study were moderately strong predictors which may be used as an adjunct to predict gender.

Objective: To assess dental arch dimensions (width, depth) in mixed dentition in a sample of Kurdish orthodontic patients. Methods: A sample of 58 dental casts (28 class I, 30 class II division 1 malocclusions) from 8 years and two months to 10 years and nine months were collected. Measurement of arch dimensions was taken, including width and depth. Differences between males and females and between class I and class II division 2 malocclusion were tested using independent t-test. Results: With gender pooled, class I group has larger UC, UE, U6, LE, L6 width than class II group, whereas class II group has larger LC width than class I group with no significant difference. The class II group has larger arch depth for maxillary measurements than the class I group, with no significant difference. While the class I group has larger arch depth for mandibular measurements than the class II group, with no significant difference except for LC. In gender dimorphism, class I group, all arch width measurements, females have a larger width than males except L6; all differences were no significant. While in all arch depth measurements, males have larger depth than females. In the class II group, all measurements of width and depth were larger in males than females, the difference in UE and U6 were significant. Conclusions: Class I malocclusion has larger width and depth than class II division 1 malocclusion, except in the maxillary depth of class II division 1 malocclusion. Males had larger arch dimensions than females.
