ABSTRACT
Background:
This study investigates various surface treatment methods to assess shear bond strength between set Cention N (alkasite-based restorative material) and new alkasite based restorative material. Assessing different surface treatments provide insights in optimizing repair procedure that enables durability of the restoration, thus potentially benefitting clinical outcomes.Methods:
A total of 48 alkasite based restorative material blocks, measuring 4 mm in depth and 4 mm in diameter, were prepared. The samples were randomly divided into 8 groups (n = 6) according to the surface treatment done. Group I Surface preparation by bur; Group II Surface treatment by laser; Group III Application of 2-step etch and rinse adhesive (Adper Single Bond 2 adhesive),Group IV Application of single step self-etch adhesive (Scotchbond Universal adhesive); Group V Bur preparation followed by application of 2-step etch and rinse adhesive; Group VI Bur preparation followed by application of single step self-etch adhesive; Group VII Laser preparation followed by application of 2-step etch and rinse adhesive; and Group VIII Laser preparation followed by application of single step self-etch adhesive. Post-surface preparation, all the specimens were restored with newly mixed alkasite material. Repair bond strength measurements were assessed with universal testing machine. Shapiro-Wilk and Levene's tests were used to check normality and Homogeneity of variance. ANOVA with post-hoc Games-Howell test and two-way ANOVA with post-hoc Bonferroni test was performed to evaluate the influence of surface preparation on the repair bond strength.Results:
Using a 2-step etch and rinse adhesive resulted in a higher repair bond strength (26.05±2.12) compared to other surface treatments. In contrast, roughening of the surface with burs led to lowest repair bond strength (17.06±3.29) (P=0.02).Conclusion:
Application of 2-step etch and rinse adhesive to the existing alkasite based restorative material provides superior bonding with the newly added alkasite based restorative material.Key words
