摘要: Abstract In fractured dentin in fifteen teeth, the mean flow produced by a hydrostatic pulpal pressure of 30 mm. Hg exceeded 0.6 μl/mm. 2 d; this implies that patent tubule can be emptied about ten times day. The histologic examination twelve teeth suggests reduction odontoblast layer aspiration cells into dentinal tubules under exposed dentin, caries, or leaky fillings is result outward physiologic gradient.
