| Abstract | ||
| The development of the new restorative materials was overwhelming during the last years. However the focus was on the bonding of these materials to the tooth structure that effected its successfulness. In this study two types of restorative materials are used (Ips e-max.zircad (ivoclar, vivadent) and Vita enamic (vita,sirona), and two type of cement using for bonding ( breeze self-adhesive and metacem adhesive resin cement). Materials and method: Forty freshly maxillary premolars extracted for orthodontic purpose divided into four groups, Group A: vita enamic cylinders were cemented with breeze self-adhesive resin cement. Group B: vita enamic cylinders were cemented with metacem adhesive resin cement, Group C: Ips.e-max zircad cylinders were cemented with breeze self-adhesive resin cement. Group D: Ips.e-max zircad cylinders were cemented with metacem adhesive resin cement. Statistical analysis was performed by using two-way ANOVA test to see if there were any significant difference among the means of experimental groups for shear bond strength, and independent sample. T-test was used to detect the difference between two resin cement within each type of material or between the two types of material within each type of resin cement. Result: Showed that Group D has the highest mean shear bond strength, and groupC has the lowest mean shear bond strength as compared with other groups. The two ways ANOVA test show that the p value between restorative materials is a high significant difference, also we can see that there is a high significant difference between the cement type materials. Conclusion: The surface treatment for the restorative material with sandblast enhance the shear bond strength, the use of total adhesive cement get higher shear bond strength than self-adhesive cement, The mean shear bond strength of Vitaenamic restorative material is higher than Ips.e-maxzircad | ||
