Abstract

This study tested if dentin adhesion is affected by Er:YAG laser. Ninety dentin disks were divided in groups (n = 10): G1, control; G2, Er:YAG laser 150 mJ, 90° contact, 38.8 J/cm2; G3, Er:YAG laser 70 mJ, 90° contact, 18.1 J/cm2; G4, Er:YAG laser 150 mJ, 90° non-contact, 1.44 J/cm2; G5, Er:YAG laser 70 mJ, 90° non-contact, 0.67 J/cm2; G6, Er:YAG laser 150 mJ, 45° contact, 37.5 J/cm2; G7, Er:YAG laser 70 mJ, 45° contact, 17.5 J/cm2; G8, Er:YAG laser 150 mJ, 45° non-contact, 1.55 J/cm2; and G9, Er:YAG laser 70 mJ, 45° non-contact, 0.72 J/cm2. Bonding procedures were carried out and the micro-shear-bond strength (MSBS) test was performed. The adhesive surfaces were analyzed under SEM. Two-way ANOVA and multiple comparison tests revealed that MSBS was significantly influenced by the laser irradiation (p < 0.05). Mean values (MPa) of the MSBS test were: G1 (44.97 ± 6.36), G2 (23.83 ± 2.46), G3 (30.26 ± 2.57), G4 (35.29 ± 3.74), G5 (41.90 ± 4.95), G6 (27.48 ± 2.11), G7 (34.61 ± 2.91), G8 (37.16 ± 1.96), and G9 (41.74 ± 1.60). It was concluded that the Er:YAG laser can constitute an alternative tool for dentin treatment before bonding procedures.

Notes

  1. The energy delivered at the end of the tip was measured with a power meter (FieldMaster, Coherent, USA) before the laser irradiation.
