Abstract
The aim of this study was to derive the best combination of teeth with which new
prediction equations could be formulated, resulting in more accurate prediction of the
combined sizes of the permanent canine and premolar teeth for the white and black
South African populations. The mesio-distal tooth sizes of each tooth from first molar
to first molar were measured for both arches on a sample of dental casts. The data
were subjected to a series of statistical correlation and regression. The sum of the
permanent upper first molar, upper central incisor and lower lateral incisor were found
to produce the most accurate predictions for both the white and black samples. The
newly formulated equations were more applicable to and accurate in the South
African white population, and for South African black female population; however,
there was no improvement in the accuracy of forecasting tooth size for the South
African black male population.
