Prediction of the size of unerupted canines and premolars in a northern Manitoban Aboriginal population
During the mixed dentition period, forecasting the size of the unerupted canines and premolars relative to the existing arch space available is an important diagnostic process. Typically, the mesiodistal dimensions of the unerupted canines and premolars have been extrapolated from measurements of th...
