Abstract
Conical chambers were cemented to dentine and connected via micropipettes to a pressure bottle to permit measurement of the rate of fluid movement across dentine under positive or negative hydrostatic pressures. Connecting the chamber to a pressure transducer permitted measurement of intra-pulpal tissue pressure through intact dentine, which averaged 24 mm Hg. Knowledge of the intra- and extra-pulpal pressures employed permitted calculation of the in-vivo hydraulic conductance of dog dentine. This was 1.35 × 10-2 and 4.51 × 10-3 μl cm-2 min-1 cmH2O-1 for molar and canine teeth respectively.
