Context: Prediction values based on a particular race cannot be considered as universal. It requires revision according to developing malocclusion and relative size of the tooth. Aim: To evaluate the applicability of Moyer’s mixed dentition analysis with derivation of regression equation for Hindu children of Bhopal city; Materials and methods: The mesio-distal width of permanent mandibular incisors, maxillary and mandibular canine and premolars were measured for 200 children of 12-16 years of age using digital vernier caliper; Statistical analysis: Student’s ‘t’ test was applied to compare the actual and predicted values and linear regression equations were derived for prediction of tooth size. The correlation between the sums of the canine, premolars in both arches and mandibular incisors was done by using coefficient of correlation (r). The Student’s unpaired t test was applied to compare the tooth dimensions between male and female;Results: Moyer’s prediction values was not an accurate method to estimate tooth dimensions in the present study sample. The mesio-distal crown dimensions in both the arches were larger in males compared to the females ;Conclusion: Statistically significant difference was present between predicted values of Moyer’s table and the values obtained in present study sample. So uses of newly devised regression equations are recommended for prediction of the combined mesiodistal width of canines and premolars in Hindu populations of Bhopal city.
