Abstract　： [Abstract] Odontogenesis in the mandibular process during an early stage of development was observed by homologous intraocular transplantation in Wistar strain rats. The embryos adopted in this study were in a stage from 11 1/2, to 12 days of pregnancy and they were strictly grouped in three stages, from 19 to 21, according to Cristie's method of computation. No tooth was formed in the transplants from 19 stage embryos, whereas tooth was formed in some of the transplants from 20 to 21 stages. Most of the teeth developed were molar-typed. The result of the present study suggests that the mandibular process acquired full signals for tooth formation at least before the 3rd branchial arches had been differentiated and that the tooth primodium was more labile during early histogenesis than in the other tissues of the mandible.
