An Estimation of Mento-Labial Angle on Standardized Digital Photographs in Gujarati Population- A Cross Sectional Study

Aim: To estimate the value of mentolabial angle in local Gujarati adults with acceptable facial profile. Materials & Methods: A cross sectional study was carried out to estimate the value of mentolabial angle on standardized digital photographs of Gujarati population (25 males and 25 females) between the age 18-25 years having well-balanced, acceptable and symmetrical face as judged by a group of three senior Orthodontists working in K.M. Shah Dental College and Hospital, SV, Piparia, Waghodia, Vadodara. Assessment of mentolabial angle was done using Dolphin imaging software 10.5. Results: Student’s t-test and Pearson’s Correlation test were applied. The measure of mentolabial sulcus angle was found higher in males (129.20° ±9.0°) than in females (125.48° ± 10.2°), stating that the local Gujarati males have more obtuse mentolabial angle than that in their female counterparts, but the difference was not statistically significant (p=0.178). Poor correlation was found between age and mentolabial angle in overall sample as well as in males and females. Conclusion: The measure for mentolabial sulcus angle in Gujarati males having normal occlusion and pleasing profile is 129.20° ± 9.0° and that in Gujarati females is 125.48° ± 10.2°. Gujarati males show higher values i.e. more obtuse mentolabial angle than females, but it is not statistically significant.
