Objective: The aim of this study was to evaluate the effect of surface treatment with ER:YAG, ND:YAG, CO2 lasers and 10% sodium ascorbate solution on immediate microtensile bond strength of composite resin to recently bleached enamel. Materials & Methods: Ninety sound molar teeth were randomly divided into three main groups (n:30) : NB (without bleaching), HB (bleached with 38% carbamide peroxide) and OB (bleached with Heydent bleaching gel assisted by diode laser). Each group was divided into five subgroups (n:6) : Si (without surface treatment), Er (Er:YAG laser), CO2 (CO2 laser), Nd (Nd:YAG laser) and As (Immersion in 10% sodium ascorbate solution). The bonding system was then applied and composite build-ups were constructed. The teeth were sectioned by low speed saw to obtain enamel- resin sticks and submitted to microtensile bond testing. Statistical analyses were done using two- way ANOVA, Tukey and Tamhane tests. Results: µTBS of bleached teeth irradiated with ND:YAG laser was not significantly different from NB-Nd group. Microtensile bond strength of OB-Er group was higher than NB-Er and HB-Er groups. The mean µTBS of HB-CO2 group was higher than NB-CO2 group; the average µTBS of HB-As and OB-As groups was also higher than NB-As group. Conclusion: Use of Nd:YAG, CO2 lasers and 10% sodium ascorbate solution could improve the bond strength in home-bleached specimens. Application of ND:YAG laser on nonbleached specimens and Er:YAG laser on office-bleached specimens led to the highest µTBS in comparison to other surface treatments in each main group. 05 09 2016 148 157 TODENTJ-10-148 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2015-9-27 2015-11-17 2015-12-29 2016-05-09 https://creativecommons.org/licenses/by-nc/4.0/legalcode 10.2174/1874210601610010148 1553506446 https://opendentistryjournal.com/VOLUME/10/PAGE/148/ https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-148/TODENTJ-10-148.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-148/TODENTJ-10-148.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-148/TODENTJ-10-148.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-148/TODENTJ-10-148.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-148/TODENTJ-10-148.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-148/TODENTJ-10-148.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-148/TODENTJ-10-148.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-148/TODENTJ-10-148.xml Lasers Med.
