ABSTRACT
Objectives: The aim of this study was to investigate the strength of shear bonding of self-cured and self-etch adhesive systems to dentin after surface disinfection with Photodynamic Therapy (PDT), Er:YAG, Nd:YAG, and KTP laser.
Materials and Methods: In the study, 6 main-groups were formed as Control, Er:YAG Laser, Nd: YAG Laser, KTP Laser, KTP Laser activated PDT and Diode Laser activated PDT. Each group was divided into two subgroups; Self-cured (Tokuyama Universal) and self-etch (Scotchbond Universal) adhesive system(n=10). 120 molar teeth were prepared to expose dentin surfaces. After disinfection and adhesive application, nanohybrid composite resin with a diameter of 3 mm and a height of 2 mm was applied to the dentin surface with the help of transparent molds. All samples were thermally cycled 5.000 times at 5°C and 55°C. Shear bond strength (SBS) test was applied to the samples in a universal test device.
Results: The differences between the Er:YAG laser group and the control, KTP and Nd:YAG laser groups of the self-cured adhesive samples were statistically significant. While the differences between the Nd:YAG laser group and the PDT groups were statistically significant (p<0.05), the differences between all other groups were no significant. In the samples applied with self-etch adhesive, while the differences between the KTP and Nd:YAG laser groups and all other groups were statistically significant(p<0.05), the difference between them was not statistically significant. (p>0.05). Self-etch adhesive applied samples showed higher bond strength values in all disinfection applications.
Conclusions: Er:YAG laser and PDT for surface disinfection applications increased the bond strength to dentin while Er:YAG laser showed the highest shear bond strenght value. The application of Nd:YAG and KTP lasers adversely affected the bond strength. In cases of using surface disinfection applications with laser for self-curing adhesive systems the Er:YAG laser or laser-activated PDT procedures are recommended.
