title: Four-year evaluation of the effect of 10% polyacrylic acid or water rinsing pretreatment on retention of glass polyalkenoate cement.
abstract: 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.
