چکیده
Classification: The following classification is based upon the inductive effect of one dental tissue upon another. In normal tooth development, it has been observed that ameloblastic epithelium exerts an influence upon the undifferentiated mesenchymal cell of the dental papilla "inducing" adjacent cells to further differentiate into odontoblasts. The odontoblasts then begin to form dentine. The formation of dentine, reciprocally, has an inductive effect upon the ameloblasts, initiating enamel matrix formation.
