Abstract: To evaluate the influence of two resin cements on microleakage of ceromer inlays. Methods Twenty recently extracted human third molars were selected. Standard inlay mesio-occluso-distal cavities were prepared, with cervical margin in enamel (mesial) or dentin (distal). The specimens were randomly divided into two groups (n=10) and indirect restorations were made with Belleglass HP system (Kerr, Romulus, MI, USA). The cavities in the first group were treated with adhesive system Single Bond and restorations were cemented with dual curing cement RelyX ARC (3M ESPE, St. Paul, MN, USA). In the second group, the ED Primer (Kuraray, Tokyo, Japan) was applied and indirect restorations were cemented with Panavia 21 EX (Kuraray, Tokyo, Japan). The specimens were coated with varnish, except for the restorations and 1 mm around them and submitted to thermal cycling and then immersed in 2% basic fuchsine solution for 24 hours. Teeth were sectioned longitudinally and leakage scores were evaluated using a stereomicroscope at 40x magnification. Data were submitted to statistical analysis (Mann-Whitney test). Results Enamel showed lower dye penetration than dentin (p<0.05). Statistical difference between cements was only observed in enamel, with RelyX exhibiting less leakage (p<0.05). Conclusion Within the limitations of the study, the substrate had a significant effect for sealing ability and RelyX ARC performed better than Panavia 21 EX only in enamel.
