ABSTRACT


Aim

More than 10 years experience in implementing the Tanaka Johnston and Moyers methods has shown that
they overestimate the sizes of unerupted canines and premolars when used in populations other than the Caucasian. This
study was designed to assess the applicability of the two most commonly used methods of mixed dentition analysis and to
attempt to derive a more accurate and precise formula to predict the sizes of the unerupted premolars and canines in a
sample of Indian population.

Methods

The sample included 200 study models (100 male, 100 female).
Tanaka Johnston's and Moyer's equations were applied to this sample and the mean differences between the actual and
estimated tooth widths were determined. New regression equations were derived using lower first molars and incisors as the
predictors.

Results

The mean difference between the actual and estimated values of canines and premolars using Tanaka
Johnston's and Moyers methods were clinically and statistically significant. Therefore new regression equations were
derived taking lower first molars and incisors as the predictors for both sexes. On validation, these equations were found to
be accurate and precise for this population.

Conclusion

It is recommended to use these equations as a method of mixed
dentition analysis for the Indian population.
