This experimental study evaluated the correlation between the marginal gap width and wear of luting cement in class I inlay restoration. Fifty Class I inlay restorations were cemented either with a single step self-etch adhesive or resin-modified glass ionomer luting cement. Following cementation of inlay, an impression was taken and epoxy resin was applied on the impression, and then measured the gap width between the tooth tissue and inlay restoration, and wear of luting cement by using a scanning electron microscope at baseline, after 3, 6, and 12 months. Data was collected and the correlation between marginal gap width and wear of luting cement was assessed as well as the differences between the wear of two luting cement were performed by student t-test; a value of p <0.05 was considered as statistically significance. It was found that the wear of luting cement was increased with the increase of marginal gap width. Furthermore, the wear of self-adhesive resin cement was statistically significant than that of resin-modified glass ionomer cement. In conclusion, the wear of luting cement increases in large marginal gap width and self-adhesive resin cement showed low wear than the resin modified luting cement.
