The Effect of pH on Fluoride Release, Surface Hardness of Glass Ionomer
ISBN: 9783844308389 / Angielski / Miękka / 2011 / 112 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The aims of this study were to detect the amount of fluoride released from the tested materials into three different storage solutions and to determine the change in the surface microhardness after storage.The amount of fluoride released from the three materials was significantly higher in acidic solutions than in neutral solutions. The Compomer released the highest amount of fluoride into the three storage solutions, while the least fluoride release was from the resin-modified glass-ionomer. The surface microhardness of the three tested materials reduced significantly after storage in...
