The aim of this study was to determine the shear bond strength of zirconium dioxide and indirect zirconium silicate filled composite resin materials bonded to dentin using self-adhesive resin cement. According to the materials used, a total of 20-disc samples with dimensions of 10 mm in diameter and 2 mm thickness were equally divided into two groups (n=10). Group I: Zirconia ML (Katana, Kurary Noritake, Tokyo, Japan) and Group II: Ceramage “indirect zirconium silicate filled resin composite material (Shofu, Tokyo, Japan). Samples of both groups were bonded with self-adhesive resin cement to dentin. Universal testing machine (Instron) was used to measure the shear bond strength. Results: A higher mean shear bond strength value (5.67 + 3.36 MPa) was recorded with Ceramage (Group II), while a lower mean value (3.44 + 1.57 MPa) with Zircona ML (Group I). Statistical analysis revealed no statistically significant difference between both tested groups. Conclusions: Indirect composite resin material filled restorative material did not show any significant increase in shear bond strength when compared to Zirconia ML restoration.
