A microrespirometic method has been devised for determining the endogenous oxygen uptake of small quantities of rat incisor pulp. Quantities from 10 to 20 mg. have been utilized. Rat incisor pulp has been observed to undergo a gradual lowering of its Qo2, from 0.364 µl. of O2 per milligram of wet weight per hour in young rats to 0.312 µl. in old rats. This is thought to indicate a declining metabolic activity of incisor pulp during the life of the rat. The decline correlates closely with the rate of incisor eruption in these periods of the rat's life.
