Figure 13.3
schematic drawings of the stages of crown-root mineralization used by
moorrees et al.
28 there are thirteen stages for
single-rooted teeth and fourteen stages for multi-rooted teeth, the difference being the addition of cleft initiation for the multirooted molars.
the first three grades illustrate the mineralizing coronal aspects of a tooth within its bony crypt.
although the stages nor-
mally are numbered, it needs to be remembered that these ordinal grades do not represent equally spaced gradations of formation. instead, they are different enough to permit visual discrimination between them. (Based on figures in m
oorrees et al.
