Abstract
Introduction: Human nose influences facial aesthetics and soft tissue harmony. Owing to uniqueness of nasal morphological characteristics, due consideration to it during treatment plan is essential. Present study aims at assessing nasal index in the Maharashtrian population and its correlation with age, gender and type of malocclusion. Materials and Methods: A sample of 410 patients was selected out of patients undergoing orthodontic treatment at the department to assess various nasal parameters. Data thus obtained was divided in groups depending on age, gender and type of malocclusion and subjected to suitable statistical analyses. Results: Mean nasal index in males was 79.08 ± 8.21 while in females was 76.65 ± 9.87 which did not differ significantly with respect to gender and age (P > 0.05). Mean nasal index differ in respect to type of malocclusion in sagittal plane and was found to be highest in patients' records pertaining to skeletal Class III malocclusion, which was statistically significant (P 0.05 for both). Conclusions: Mean nasal index in Maharashtrian male is 79.08 ± 8.21 and in females is 76.65 ± 9.87 (mesorrhine nasal type). The mean nasal index was found to be reduced in Class II malocclusion cases as compared to Class I and Class III malocclusion. The facial index, nasal index and dorsum base ratio also did not show statistically significant correlation.
