Cephalometric characteristics of indian adults: with special reference to delhi ncr hospital

Objectives and Introduction The majority of the predicted value used in Cephalometry which is used in assessing and performing the orthodontic procedure is Caucasian. In India (Delhi NCR), there is growing demand for its treatment, but there is little knowledge available in Cephalometry. So, the question arises, “Should we use Cephalometric norms from other countries?” To find the answer for this question, we have conducted a research in Delhi NCR hospitals for determining the craniofacial morphological characteristics of a group of Indian subjects. Methodology The methodology was conducted from the month of January 2019 to June 2019.We have conducted an observational analysis on scout view scan graphic images of patients aged 25 to 45 years at the Delhi NCR Hospitals and remaining work at dental college Azamgarh. The mean score and standard deviations of 15 Cephalometric variables were determined. To calculate the reference values, we used indicator which means 95 percent of confidence interval as the best estimator of our population measures. Results The total number of participants was 1200, with an average age of 31.3 years. The only differences between the sexes in Indian subjects were for SNB and SND tests, which were higher in men. The Indian population had a protrusive Dento-Alveolar system with higher average values compared to Caucasian values, with an exception of inter-incisal angles 118.3o and SND 68.8o, which showed a lower value against Steiner 131 and 79. European Journal of Molecular & Clinical Medicine ISSN 2515-8260 Volume 08, Issue 04 , 2021 646 Conclusion The difference with SNB and SND measurements both between men and women in India is that the men in India are having higher SNB and SND values. Just in few measurements, sample statistics differ significantly from the Caucasian averages in India. Taking these differences into account, we were able to propose a map of Cephalometric values, which have given a clear indication of the Indian type.
