Background and Objective: The objective of present study is to evaluate the applicability of Moyer's mixed dentition analysis in Maharashtrian children of India.
Materials and Method: Present study consist sample of 200 (100 females and 100 males) Maharashtrian children of India. All participants were in the age group of 13 to 16 years old. Children selected were having fully erupted all permanent teeth. Actual mesiodistal dimensions of four permanent mandibular incisors, upper and lower canines, and premolars of right and left sides were measured using digital vernier caliper which had a resolution of 0.01mm. These all measurements were then averaged.
Statistical Analysis: The statistical analysis of obtained data was performed using SPSS 20.0. Student t test was used to compare between actual measurements and predicted values obtained with the Moyer’s prediction tables. To find out the accuracy of the formed prediction equations the coefficient of determination (r2) was calculated. To determine the validity of the proposed equations standard error of estimate (SEE) was calculated.
Results: The comparable differences found between the actual and predicted values of moyer’s prediction table were statistically very highly significant in males and females (P < 0.000). No statistical significant difference was seen at male mandibular 75th percentile and female maxillary 50th percentile between the actual measured findings and moyers table.
Conclusion: There was comparable and statistically highly significant difference found between moyer’s prediction measurements and measurements found in present study. Study on larger sample is required to test the accuracy of the predicted equation.
