Problem statement: The purpose of this study was to compare the shear bond strength of four cariostatic restorative materials to dentin of permanent teeth. Approach: Restorative materials which have used in the study were composite P60 (3M), conventional glass ionomer (Fuji II, GC), light cured glass ionomer (Vitremer, 3M), compomer (F2000, 3M) and flow compoglass (Vivadent). This study was in vito study 4 groups of 10 teeth were used. Buccal surface of teeth was cut by high speed diamond cylinder burs, no 0.9 and dentin was exposed. Dentin surface was polished using “rubber cup and pumice”, at low speed and repaired with one of the restorative materials according to the manufacturer's instructions. Restorative materials were placed on dentin using cylinder which had diameter of 3mm and length of 4mm. Determination of shear bond strength was performed using a universal testing machine at a speed of 0.5 mm/min. For statistical analysis, kruskal-wallis and ANOVA was used. Results: Ompomer had the lowest mean shear bond strength, 18.94 ± 1.85 and flow compoglass had the highest mean shear bond strength, 30.79 ± 3.02. Shear bond strength of light cured glass ionomer (30.79 ± 3.02) and conventional glass ionomer (22.64 ± 5) were respectively lower than flow compoglass. ANOVA test showed that the difference between shear bond strength of these materials was significantly difference (p<0.05), but these was no significant difference between shear bond strength of flow compoglass and light cured glass ionomer (p>0.05). Also there was significant difference between shear bond strength of these two materials and self cure glass ionomer, compoer (p<0.05). Conclusion: Flow compoglass had the highest shear bond strength and light cured glass ionomer, self cured glass ionomer and compomer, respectively had lower shear bond strength than flow compoglass.
