Abstract

In 9 patients, 60 class V restorations were evaluated clinically and by scanning electron microscopy. All lesions were treated with glass-ionomer combined with composite resin. In 27 fillings (group A) the glass-ionomer lining cement was etched, whereas in 33 fillings (group B) the composite material was applied directly on the unetched glass-ionomer liner. Clinically, the retention of the fillings after one year was 100%. The margins of the fillings were checked with different explorers and found to be acceptable. Scanning electron microscopy of the margins of the fillings showed disappointing results. One week after placement of the fillings, only 16.2% (group A) and 7.4% (group B) of the cervical margins in dentin were rated perfect. After one year, even more cervical bond failures were observed. 9.7% perfect margins were found in group A, 3.2% in group B. Etching of the glass-ionomer liner had no influence on the cervical bond failure of the class V fillings.
