ABSTRACT
Aim:
The aim of this study was to do a 3-dimensional analysis of the upper and lower dental arch forms and compare the same between male and female South Indian subjects who were not previously treated with fixed orthodontic appliances.
Materials and Methods:
The sample consisted of 3D scans of dental casts from 50 untreated patients(25 males and 25 females) in permanent dentition. An assessment of the arch form was performed using angular and linear values on scans using a software(MEDIT).The data was tabulated and statistically analyzed using SPSS software and Student’s t test(2- tailed) was used to determine statistical significance of differences in measurements between the two groups.
Results:
In male subjects the intercanine, intermolar, interpremolar diameters and arch depth were significantly greater than females and there was a statistically significant difference (p value=<0.05).
Conclusion:
Ovoid arch form is commonly seen in both South Indian males and females followed by broader arch forms in males and tapered arch forms in females. South Indian males have wider arches when compared to females.
