Abstract:
The aim of this study was to evaluate the effect of Er, Cr: YSGG laser irradiation in the physics properties of the different dentin bonding systems (DBS) applied in dentin substrate.This study presented two variation factors: laser, divided into two levels (Er, Cr: YSGG [L] and Control - not irradiated [C] ) and DBS divided into four levels (AdperTM Scotchbond Multipurpose [MP], AdperTM Single Bond 2 [SB] , ClearfilTM SE Bond [CSE], ScotchbondTM Universal Adhesive [SU] ). The response variables were water sorption/solubility (mg/mm3) [WS/WSB], degree of conversion (%) [DC] , microtensile bond strength (MPa) [MS] and scanning electron microscopy [SEM] for descriptive analysis. After application of DBS over dentin substrate and before curing, in the L groups the irradiation was performed over the primer on MP and CSE and after primer/adhesive on SB and SU. After 7 days, the specimens were cut to obtain squared-shape blocks for WS/WSB, slices for one-year DC/MEV and sticks for one-year MS. The data was analyzed by two-way ANOVA, followed by Tukey test for multiple comparisons (p 〈 0.05).All irradiated groups presented lower WS/WSB than respective control groups. For DC, it was noted a significant difference only for DBS factor. However, laser irradiation promoted a significant drop in MS values, except for SU-L group. In SEM, greater penetration depth of resin tags were found for total-etch DBS, especially when laser irradiated.
