Rate of growth of lower incisor teeth in the adult white rat.
A single dose of 14C was given to adult rats and the animals were sacrified 4 days later. The thickness of dentine formed during this period was measured in radioautographs of incisor teeth. It appeared that the thickness of dentine laid down per day was 15 microns. This rate was about one seventh of the rate of growth in immature incisors. No new dentine formation was observed in molar teeth.
