Background: Acid etching of enamel appears to improve retention by selectively eroding certain hydroxyapatiteformations and facilitating penetration by the development of resin tags. Aim of study: To evaluate shear bond strength(SBS) of flowable composite to non-lased and lased groups, compare the (SBS) of flowable composite between Totaland Self-etch in non-lased and lased groups, and failure mode analysis.Materials and Methods: Forty bovine incisorswere used, enamel surfaces was grounded by silicon carbide paper and samples were randomly assigned into twomain groups (Group A: Non lased n=20, Group B: lased prepared n=20). Each main group was subdivided randomlyaccording to the adhesive systems that used which are: total-etch adhesive and self-etch adhesive, which were appliedto the prepared enamel surface according to manufacture instruction. Composite rod applied over the bonded area andcured. Samples were stored in distilled water at 370 for 24 hours. The evaluation of shear bond strength was employedby the use of universal testing machine. Results: The results of Student’s t-test showed that there was no significantdifference between the lased and non-lased enamel groups (P= 0.311). One–way ANOVA test and Duncan's MultipleRange test that compare shear bond strength between total and self-etch adhesives showed no significant differencein both lased and non-lased enamel groups. Conclusion: The mean shear bond strength and enamel surface etchingobtained with an Er,Cr:YSGG laser was not comparable to that obtained with non- lased enamel surface.
