We heve made a histochemical study concerning the TPN diaphorase in the developing teeth and alveolar bone of the rats (15-20 days fetuses and 5 days old after birth) by adapting Nitro BT method.
TPN diaphorase in the developing teeth showed a strong activity in the differentiated odontoblasts and ameloblasts. On the other hands, a weak activity was observed in the undifferentiated odontoblasts and ameloblasts.
