N2 - A method for measuring the effective osmotic pressures of solutions across dentine is described. The ratio between the effective and theoretical osmotic pressures is termed the reflection coefficient. This value ranges from 0, indicating lack of discrimination between solute and water, to 1.0, indicating complete solute impermeability. In dentine, the reflection coefficients of urea, various salts and sugars were about 0.0001. Thus, the effective osmotic pressures of these solutions are only about 10-4 of their theoretical osmotic pressures. The reflection coefficient formalizes the degree of semipermeability of dentine.
