Abstract

The resistance to fluid movement through dentine was analysed in terms of 3 resistances placed in series: (1) surface resistance due to the presence of debris occluding dentinal tubules, (2) an intratubular resistance due to mineralized nodules and internal irregularities within the tubules, (3) a pulpal resistance due to the presence of odontoblast processes and cell bodies within the tubule. Surface resistance accounted for 86 per cent of the total resistance. In addition, the resistance to fluid movement varied with the direction of pressure application being lowest in the enamel to pulp direction.
