Red blood cells were forced into dentinal tubules in vitro under known hydrostatic pressures. This resulted in a 1 7-fold fall in the hydraulic conductance of dentin. The histologic appearance of red blood cells forced into dentin in vitro was very similar to that found in dog pulps following full crown preparations without adequate cooling in vivo.
