The development of cytotoxic changes in the dental pulp is due, in large part, to the permeability of dentine. That is, if dentine were impermeable, these changes would not occur. Dentine permeability is not uniform; it tends to be low over the incisal edges but high over the pulp horns of posterior teeth. It is relatively low beneath the amelo-dentinal junction or the cemento-dentinal junction but increases dramatically near the pulp chamber. Buccal dentine is less permeable than occlusal dentine, while radicular dentine permeability is much lower than that of coronal dentine. The presence or absence of a smear layer has a profound influence on dentine permeability. Tubular sclerosis or dental caries produces large reductions in dentine permeability. Dentine is an important barrier to the diffusion of substances toward the pulp. It both restricts diffusional surface area and dissipates the concentrations of substances driving diffusion across dentine. Further, there is evidence that dentine can interact in many different ways with a variety of solutes as they diffuse across dentine. Newin vitromodel systems can be modified to simulate more closely conditionsin vivowhere dentine is interposed between various dental materials and the pulp. Thus, the development ofin vitromethods of biocompatibility testing that include dentine should improve the correlation between laboratory and clinical results.
