“…Subsequently, specimens were sectioned vertically using the sectioning machine (Non Stop, Germany), to provide 36 dentin-composite rectangular slabs with a cross-section of 1*1 mm². 15 Bond Strength Testing The micro-shear bond strength of the samples was tested on a micro-tensile tester machine (COMPACT GAUGE 200N, Bisco. Inc).…”

“…Moreover, Er:YAG laser showed less penetration in dentin and had less effects on the ultimate tensile bond strength of dentin when compared to diode laser or CO2 laser 7) . At this juncture, it must be pointed out that although available literature has reported on various aspects and parameters about Er:YAG laser, it remains to be clarified whether the application of Er:YAG laser is really effective in improving adhesion to bonded restorations 8) .…”

The purpose of this study was to investigate the chemical characteristics of dentin after Er:YAG laser irradiation using various output energies with or without water irrigation. Analysis was carried out by means of attenuated total reflectance Fourier transform infrared spectroscopy (FT-IR/ATR) and X-ray diffraction (XRD). Furthermore, the relative infrared peak intensities of dentin specimens were compared statistically. Results showed that Er:YAG laser with an output energy of 100 mJ/pulse with water irrigation did not cause any detectable change in dentin. However, a higher energy output or the absence of water irrigation affected the organic portion of dentin. With XRD, no obvious phase changes were observed between the XRD pattern of the control (non-irradiated) dentin powder and those after Er:YAG irradiation -regardless of Er:YAG laser output energy or dehydration condition. It was suggested that the intrinsic water content of dentintogether with extrinsic water irrigation -were important factors to achieving the desired outcome of dentin ablation by Er:YAG laser.

“…The surface treatment, however, is still controversial. Several studies (6)(7)(8)(9)(10)(11)(12) have focused on the efficiency of the laser on the removal of carious tooth structures, surface pretreatment and cavity preparation. As laser irradiation produces a disorganized, indiscriminate destruction of organic and inorganic components (9, 13) and influences the availability of calcium ions on the tooth structure (14,15), the mechanical and chemical adhesion of GIC is inherently affected (16).…”

Background: Dentin sensitivity is one of the most important problems in dentistry. Enamel loss due to root exposure is serious issue and common exposure is one of the reasons for dentin hypersensitivity. There are different methods for solving this problem. One of the most conservative and least expensive methods is use of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste. Objectives: The aim of this study was to evaluate shear bond strength of GIC to dentin, with or without laser, CPP-ACP paste and polyacrylic acid treatments. Materials and Methods: Fifty sound human third molars were bisected in a mesiodistal direction using a diamond disk. Using 400, 600 and 800 grit silicon carbide paper, dentin surfaces were exposed. The teeth were divided into five groups. In groups A, B, D and H, CPP-ACP (GC tooth mousse Itabashi-Ku, Tokyo, Japan) was applied for one hour the first day and repeated at the same time of day for a total of five days. In groups B, C, D and E, the specimens were subjected to laser for 10 seconds using Er, Cr: YSGG laser. In groups B, C, H and G, specimens were treated with 10% polyacrylic acid for 20 seconds. A plastic tube containing GI was positioned over the tooth. Samples were loaded in shear bond using a Universal Testing Machine (Zwick/Roell, Germany), at a 0.5 mm/minute crosshead speed. Results: Despite the failing of groups A and D, group analysis showed that there were no significant differences between the groups. The predominant type of fracture in all groups was adhesive. Conclusions: Application of CPP-ACP, without preconditioning with polyacrylic acid, can decrease shear bond strength. Laser irradiation has no effect on shear bond strength of GIC to dentin in this condition.
