Özet

This study was aimed to evaluate the effects of Er:YAG and Er,Cr:YSGG laser irradiation and adhesive systems on the

microtensile bond strength of Fusio Liquid Dentin (FLD) which is a self-adhering composite (SAC). Twenty-four freshly

extracted human molar teeth were collected, and the enamel was removed from the occlusal surface to obtain a flat dentin

surface. Twenty-four teeth were randomly divided into eight groups: Group 1: only Fusio Liquid Dentin (FLD) (Petron Clinical,

Orange, California, USA) was applied to the dentin surface; Group 2: 37% Phosphoricacid (i-GEL, Medicinos Linija

UAB, Lithuania) + FLD; Group 3: Single Bond Universal (SBU) (3 M ESPE, Germany) + FLD; Group 4: Adper Easy One

(AEO) (3 M ESPE, Germany) + FLD; Group 5: Er:YAG laser + AEO + FLD; Group 6: Er:YAG laser + SBU + FLD; Group

7: Er,Cr:YSGG laser + AEO + FLD; and Group 8: Er,Cr:YSGG laser + SBU + FLD. After thermocycling, 1 × 1 mm2

sticks

were used for the μTBS test (n = 10). Two sticks per group were used for SEM analysis. Fractured sample surfaces were

evaluated using a stereomicroscope. Group 8 showed the highest μTBS value (13.70 MPa), whereas Group 1 showed the

lowest μTBS value (5.60 MPa). There were no significant differences between Groups 2, 3, and 4 (P = 0.324), but Groups 5–8

showed statistically significant results that were higher than Groups 1–4 (P = 0.012). Adhesive failure mode was predominant

followed by mixed failure. The evaluation of bonding of the FLD to dentin showed that the combined use of Er:YAG and

Er,Cr:YSGG lasers with SBU and AEO on dentin surfaces improved the dentinal bond strength of the FLD.
