Four-year evaluation of the effect of 10% polyacrylic acid or water rinsing pretreatment on retention of glass polyalkenoate cement.
To optimize the bonding of glass polyalkenoate (ionomer) cement to dentin, different conditioning methods have been suggested. The effect of two easily applied conditioning methods, a 10-15 seconds cleaning with a 10% polyacrylic acid or rinsing with copious amounts of water, was compared in class V abrasion/erosion lesions. The cervical lesions were restored, without any form of mechanical cavity preparation, with an anhydrous glass ionomer cement. During a 4-yr period, 137 restorations were evaluated every 6 months. Cumulative loss rates after 4 yr were 15.6% for the polyacrylic acid group and 21.9% for the water rinsing group. The difference was not significant. No secondary caries was registered.
