“…In the present study, altering the surface of the PMMA resin by Er:YAG laser irradiation before application of resilient material resulted in higher tensile strength values than those of the control group. This finding is consistent with the results of Akin et al, 11 who found that Er:YAG laser treatment at 200 mJ, 10 Hz, and 2 W for 20 seconds increased the tensile strength between the resilient liner and denture base resin. However, Nd:YAG and potassium titanyl phosphate lasers were ineffective.…”

“…According to the results of this study, the airborneabraded group exhibited significantly higher bond strength than the control group. This finding contradicted the results of Gundogdu et al 14 and Akin et al, 11 but was consistent with the results of Storer 12 and Usumez et al 15 The enhanced bond strength achieved in this study could be attributed to larger size of alumina particles (110 µm) that created larger pits and depressions, thereby the resilient lining material could penetrate into them more easily. The presence of definite cavities on surfaces hit by aluminum oxide particles indicated this.…”

“…Nevertheless, the results of investigations are controversial. [11][12][13][14][15] Gundogdu et al 14 and Akin et al 11 reported that roughening the acrylic resin with airborne particle abrasion with 50-µm alumina particles resulted in lower bond strength compared to control specimens. Similar findings were reported by Atsü and Keskın, 16 who found that airborne abrasion with 50-µm alumina and 30-µm silica-coated alumina particles did not improve the bond strength of resilient lining material to denture base resin.…”

“…To solve this perplexing problem, investigators have focused on methods to alter the denture base resin surface. These methods include airborne particle abrasion, [11][12][13][14][15] tribochemical coating, 16 chemical etching, 14 and laser treatment. 14,15,17,18 A study showed that roughening the acrylic surface results in almost twice the adhesive bond strength of resilient lining materials in comparison to smooth surfaces.…”

“…Nevertheless, limited and inconsistent findings are available regarding the effectiveness of laser treatment in improving bond strength between soft lining materials and denture resin. 11,14,17,21 In the oral cavity, liner denture base resin interface is frequently subjected to thermal stresses. It has been found that the bonding between resilient liner materials and denture resin is affected by aging in water and thermocycling.…”

Aim:The aim of this study is to evaluate the effects of three different surface treatments and thermocycling on the tensile strength of a silicone lining material to denture resin. Materials and methods:A total of 96 cube-shaped specimens were fabricated using heat-cured polymethyl methacrylate (PMMA) denture base resin. Three millimeters of the material was cut from the midsection. The specimens were divided into four groups. The bonding surfaces of the specimens in each group received one of the following surface treatments: no surface treatment (control group), airborne particle abrasion with 110 µm alumina particles (air abrasion group), Er:yttrium aluminum garnet laser irradiation (laser group), and air abrasion + laser. After the lining materials were processed between the two PMMA blocks, each group was divided into two subgroups (n = 12), either stored in distilled water at 37ºC for 24 hours or thermocycled between 5 and 55ºC for 5,000 cycles. The specimens were tested in tensile and shear strength in a universal testing machine. Data were analyzed with two-way analysis of variance and Tamhane's post hoc tests (α = 0.05). The mode of failure was determined, and one specimen in each group was examined by scanning electron microscopy. Effect of Different Results:Surface-treated groups demonstrated significantly higher tensile strengths compared to the control group (p < 0.001). Nonetheless, no significant differences were found between surface-treated groups (p > 0.05). The tensile strength was significantly different between thermocycled and waterstored specimens (p = 0.021). Conclusion:Altering the surface of the acrylic denture base resin with air abrasion, laser, and air abrasion + laser increased the tensile strength. Thermocycling resulted in decrease in bond strength of silicone-based liner to surface-treated acrylic resin.Clinical significance: Pretreatment of denture base resins before applying the soft liner materials improves the bond strength. However, thermocycling results in decrease in bond strength of soft denture liner to surface-treated acrylic resin.

To compare the efficacy of different surface treatments (fiber post) with laser activated irrigation (LAI) technique (various root canal solutions) on root canal dentine in terms of push‐out bond strength (PBS) in a fiber post. In this study, 200 premolars were assigned into groups according to various irrigation techniques: 2.5% sodium hypochlorite (NaOCl), 17% ethylene diamine tetra acetic acid (EDTA), and 17% EDTA + LAI. In addition, the fiber posts were separated into five groups, (n = 30) according to the surface pretreatment performed: sandblasting, hydrofluoric acid (HF), Erbium, Chromium:Yttrium Scandium‐Gallium‐Garnet (Er,Cr:YSGG) laser, Neodymium‐Doped Yttrium Aluminum Garnet (Nd,YAG) laser and as untreated surface. The posts were cemented using dual‐cure resin cement and subjected to a PBS test. Data were analyzed by one way‐ANOVA, Tukey, and Tamhane T2 tests. The PBS values were increased in all parts of the tooth in the EDTA and EDTA + LAI treated groups and in groups treated with Er,Cr:YSGG laser fiber posts. In groups in which EDTA and EDTA + LAI were applied, it was observed that dentinal tubules were open according to the distribution and number of dentinal tubule configurations. The improvement of the PBS between fiber post/resin cement/root dentine was observed via the use of fiber post surface treatments with different irrigation techniques.

There are conflicting results in the literature and divergent manufacturers' recommendations concerning the retention properties of implant restorative cements, and they can provide inadequate retention of implants, especially short or single implants. The objective of this study was to investigate the effects of sandblasting and different types of laser irradiation on the interfacial bond between titanium and resin cement through shear testing. A total of 60 samples (10 mm in length and 12 mm in diameter) were cut from titanium rods. The samples were divided into four equal groups according to the surface treatment: control, sandblasted, Nd:YAG laser-irradiated, and Er:YAG laser-irradiated. After surface treatment, the implant restorative cements were applied to the titanium samples which were stored in distilled water at 37°C for 24 h. The samples were then subjected to shear bond strength testing using a universal testing machine with a crosshead speed of 1 mm/min. The data were analysed with the Kruskal-Wallis and Mann-Whitney U tests (α = 0.05). The highest mean bond strength was observed in the control group, followed by the sandblasted group. A statistically significant difference in shear bond strength was found between the sandblasted group and both the laser-irradiated groups (p < 0.05). The Nd:YAG laser-irradiated group had a higher mean shear bond strength than the Er:YAG laser-irradiated group. The treatments applied to the titanium surface did not improve the strength of the bond to the implant restorative cement.
