Abstract

Background: Cephalometric norms are important in assessing optimal treatment alternatives in different population. Universal norms are based on cephalometric data from Caucasian population and based on one size fits all ideology. Aim of the study was to create a database of normative type and determine gender dimporphism on three dimensional cephalometric analysis for Central Indian population. The secondary aim was to observe correlation between different skeletal and dentoalveolar variables.
Materials: Craniofacial CBCT scans of 60 adult subjects (30 females and 30 males; age group of 21 years and above) having skeletal class I relation and normal occlusion were included in the study. Landmark identification and measurements of skeletal and dentoalveolar variables were done on three dimensional life size model and compared for facial symmetry, gender dimorphism, correlation between skeletal and dentoalveolar variables and condylar and ramal variables.
Results: Cephalometric norm of central Indian population showed a tendency towards class II skeletal relationship and convex profile. Antero-posterior, vertical and transverse facial variables differed significantly for males and females suggesting gender dimorphism. Greater body length, facial height, facial width and basal curve length of maxilla and mandible were observed in males (p?0.05). Pearson correlation showed significant correlations among various skeletal variables, skeletal and dento-alveolar variables and condylar and ramal variables in the population.
Conclusion: Baseline values play important part in determining abnormalities and posttreatment objectives for the population. A strategic approach is important based on racial and gender differences while planning orthodontic treatment.

Keywords: Three dimensional cephalometric analysis, Central Indian population, facial symmetry, correlation between cephalometric variables, condylar and ramal variables.
