Comparative Concentration of Various Constituents of Blood Plasma and Dental-Pulp Fluid

Abstract
Dental pulp fluid obtained by inserting a capillary glass tube in a hole drilled through the enamel and dentin to the pulp chamber. Analysis of the blood plasma and dental pulp fluid revealed no significant difference in the concentration of chlorides, magnesium, urea and alkaline phosphatase in these two fluids. Calcium and inorganic phosphorus were at significantly higher levels in the plasma than in the pulp fluid. These data are interpreted to indicate that a portion of the inorganic phosphorus like that of the calcium in the blood plasma is non-diffusible.
