8.  1-decideous dentition
 2-permanent dentition
 3-mixed dentition

12. Succedaneous teeth:
twenty decideous teeth are
replaced by twenty
permanent teeth.
 Incisors and canines
replace their counter
parts
 Premolars replace the
decideous molars
Permanent molars are not
consider as a succedaneous
teeth (no predecessors)
