Water uptake characteristics of BisGMA-based composites incorporating untreated and surface-treated hydroxyapatite (HA) with a silane coupling agent have been investigated. The water absorption and desorption behaviour of these composites obeyed the classical diffusion theory. The diffusion coefficients of the composites during first absorption were very similar to that for the base resin, suggesting that the water uptake process occur mainly in the resin matrix. The incorporation of HA reduced… CONTINUE READING
