title: Effects of Dentin Surface Treatments on Hypersensitivity to Bond Strength of Restorations: An In Vitro Study.
abstract: This study evaluated the effects of desensitizing treatments on the shear bond strength (SBS) of adhesive resin cement (Rely X U100) applied to dentin. Human molars (n = 120) with exposed dentin were divided into 12 groups. In the experimental groups, dentin surfaces were treated with (1) an erbium:yttrium- aluminium-garnet (Er:YAG) laser, (2) a neodymium:yttrium-aluminium-garnet (Nd:YAG) laser, (3) glutaraldehyde (Gluma)-, (4) fluoride (Aqua Prep-F)-, and (5) oxalate (BisBlock)-containing desensitizing agents, (6) Gluma preceding the Er:YAG laser, (7) Aqua Prep-F preceding the Er:YAG laser, (8) BisBlock preceding the Er:YAG laser, (9) Gluma preceding the Nd:YAG laser, (10) Aqua Prep-F preceding the Nd:YAG laser, (11) and BisBlock preceding the Nd:YAG laser, in groups EL, NL, G, F, O, EL-G, EL-F, EL-O, NL-G , NL-F, and NL-O, respectively. Then, lithium disilicate ceramics were cemented to the treated surfaces. Subsequently, an SBS test was performed and the data were statistically analyzed (α = .001). The results suggested that the combined treatment of Gluma preceding Er:YAG laser increased the bond strength of ceramic to the dentin surface using a self-adhesive resin cement.
