Objective.
To investigate the shear bond strength of self-adhering flowable resin composite, to dentin, after exposing it to Er:YAG laser radiation, at different energy densities.
Materials and Methods.
Sixty freshly extracted human third molars were randomly divided into five groups ( n = 12 ).
In the control group, dentin was left unirradiated, whereas, in the other four groups, dentin was irradiated with Er:YAG laser in noncontact mode (MSP mode = 100 µs; 10 Hz; beam diameter: 1.3 mm; speed of 1 mm/second; air 6 mL/min; and water 4 mL/min), and respectively, with the following level of energy (50 mJ, 60 mJ, 80 mJ, and 100 mJ).
Then, self-adhering flowable resin composite was bonded to all prepared dentin surfaces.
Shear bond strength (SBS) was applied and fractured surfaces were examined using scanning electron microscopy.
Results.
SBS values showed significant differences in 60 mJ ( P < 0.05 ) compared to other groups.
Morphological evaluation revealed tags or plugs in dentinal tubules, especially when 60 mJ and 80 mJ were used.
All four groups tended to leave more residues on the dentin surface, than the control group.
Conclusion.
Er:YAG dentin irradiation may enhance SBS of the self-adhering flowable resin composite when it is used at the appropriate low level of energy density.
