Abstract
AIM: To evaluate four regression equation-based mixed dentition analyses in a Patna population and assess their accuracy and correlation. MATERIALS AND METHODS: This study analyzed 84 school children aged 11-13. Dental impressions were used to measure tooth dimensions with calipers. Measurements were compared to values from different regression equations using a paired t-test. RESULTS: The average disparity between the real and estimated values of canines and premolars exhibited notable clinical and statistical significance (P < 0.001). CONCLUSION: All four regression equations were not accurately applicable to this population.
