Mixed Dentition Analysis: A Revised Equation for New Generation

Abstract

Abstract Abstract: Aim: Racial difference is an important factor in tooth size variability. The present study was thus aimed to assess the applicability of Tanaka and Johnston method for predicting the mesiodistal dimensions of canine and premolars in children of Panchkula, Haryana. Methods: Dental study models of 200 children were analysed to check the applicability of Tanaka and Johnston method of mixed dentition analysis. Results: Differences have been found in the means of actual dimensions of canine & premolars and values derived by regression equation of Tanaka and Johnston by Student’s t-test and therefore formulated a new equation. Conclusion: Tooth size differences amongst races are an important variable that must be considered before the formulation of prediction equation. The proposed new prediction equations derived in the present study are possibly more appropriate to be used for mixed dentition analysis in a population of Panchkula, Haryana.
