| Summary: | Introduction: The Moyer’s mixed dentition analysis forms an
essential part of diagnostic procedures to determine adequacy
of the space available for the erupting permanent teeth.
However, its reliability among different racial groups has been
questioned.
Objectives: The objectives of this study were to test the reliability
of Moyer’s method and to produce new regression equation for
Bangalore population for predicting the mesiodistal diameters
of the unerupted permanent canines and premolars.
Materials and Methods: Data was collected from study models
of 400 randomly selected Bangalore subjects aged 13 to 16
years with fully erupted, intact dentitions and no significant
malocclusion. The mesiodistal widths of the incisors, canines
and premolars of both arches were measured. This data was
then utilized to predict the mesiodistal widths of canines and
premolars and further compared with Moyer’s table.
Conclusion: It was found that 50% is more applicable to boys
and 75% to girls. The canine premolar segment in both arches
is statistically larger in men than in women (p<0.05). New
regression equation was formulated, the accuracy of which
needs to be evaluated further in a larger sample. |
