A preliminary study of the water movement across dentin bonded to glass-ionomer cements (original) (raw)

This preliminary study investigates the movement of water across dentin bonded to glass-ionomer cements. The research highlights the dual nature of glass-ionomer adhesion to dental tissues, involving micro-mechanical interlocking and chemical bonding. Observations indicate that glass-ionomer cements can uptake water from moist dentin, leading to potential postoperative sensitivity and suggesting that their application should involve slightly moist dentin. The study also notes the formation of spherical bodies within air voids, which may enhance the compressive strength of the cement over time.
