Abstract

Background: Orthodontic patients primarily seek treatment for aesthetic reasons and due to paradigm shift from hard tissue to soft tissue, nasal morphology with associated structure present in the middle third of face has drawn attention. Hence the retrospective study compared and correlated parameters between nasal morphology and gender dimorphism, skeletal pattern and skeletal malocclusion. Preorthodontic cephalograms of 180 patients were randomly selected following exclusion and inclusion criteria from North Indian population. Cephalograms were divided into three different groups according to various skeletal growth pattern, gender dimorphism and skeletal malocclusion and were further correlated with nasal parameters of each sample groups. Results: The results stated that there was a statistically significant correlation and differences were found between nasal parameters such as NLth(p=0.005), NTP(p=0.004) and skeletal parameters in males and females The results also explained that nasal parameters showed significant correlation with skeletal parameters among various growth pattern. There was statistically significant difference found NLth(p=0.035) and NTP (p=0.029) among growth pattern. On comparing nasal parameters in different classes of malocclusion, nasal parameter LNLA seems to be affected in all the three classes. Conclusion: The study concluded that nasal parameters get affected by growth pattern, skeletal malocclusion and sexual dimorphism in an individual.
