Facial Soft Tissue Cephalometric Norms in a Central

2014 
Aim: Based on Arnett’s soft tissue cephalometric analysis (STCA), the present study aims to establish cephalometric norms for central Indian population and any significant sexual dimorphism. Materials and methods: The digital lateral cephalograms of 100 adults (50 males and 50 females) between the age group of 17 to 25 years with normal occlusion and well-balanced faces were obtained. These radiographs were manually traced according to Arnett’s STCA. The obtained values were statistically analyzed to establish STC norms for central Indian population. Results: Significant differences were observed in the lateral cephalometric norms between the central Indian and the white samples. Also significant sexual dimorphism was noted between males and females of the central Indian sample. Conclusion: Ethnic differences exist between central Indian and white sample which should be considered when formulating an orthodontic treatment plan for Indian population.
