Fifty-one restorations of the tunnel type were performed with "cermet" cement on primary molars. The restorations were assessed clinically, radiographically, and by direct examination of the proximal surface 6 months (group I) and 12 months (group II) after placement. The incidence of fractured marginal ridges was found to be 3.8% in group I and 4.2% in group II. All restorations had their occlusal portion intact and were caries-free. Clinically detectable occlusal wear was found in 7.7% of teeth in group I and in 4.2% of teeth in group II. No correlation was found between direct and radiographic assessment of proximal caries. White spots, without carious penetration, were detected on 53.8% of proximal surfaces at 6 months and on 60.0% of proximal surfaces at 12 months.
