Effect Of Surface

The aim of this study was to evaluate the effect of surface treatment and storage time on immediate repair bond durability of methacrylate- and ormocer-based bulk fill composites. In total, 265 discs were divided into 32 groups (n = 8/group) according to: (1) Material: X-tra fil and Admira Fusion X-tra; (2) Surface treatment: oxygen inhibition; matrix; Futurabond M+; Silane/Futurabond M+; Admira Bond; Silane/Admira Bond; ceramic repair system; and Silane/Cimara bond; and (3) Storage time: 24 h and 6 months. Each disc received three micro-cylinders from the same material. Specimens were subjected to micro-shear bond strength testing either at 24 h or 6 months. Data were analyzed using ANOVA/Tukey’s test/Student t-test (p = 0.05). All experimental factors had significant effect on bond strength (p < 0.0001). Drop in bond strength was noticed in both materials after six months (p < 0.05), except for Admira Fusion X-tra treated with silane/cimara adhesive (p = 0.860). Both materials showed insignificant values with Admira bond either at 24 h or 6 months (p = 0.275 and p = 0.060, respectively). For other treatments, X-tra fil showed significantly higher values at 24 h and 6 months (p < 0.05). Ceramic repair system can be used to immediately repair both methacrylate- and ormocer-based composites.

Abstract The aim of this study was to evaluate the effect of silanes, thermal cycling and acid etching on the shear bond strength (SBS) of metallic brackets to feldspathic ceramic. Feldspathic ceramic cylinders (Groups 1, 2, 5 and 6) were etched for 60 s with 10% hydrofluoric acid and Groups 3, 4, 7 and 8, without acid etching. Two layers of silane Clearfil Ceramic Primer (CCP, Groups 1 to 4) and two layers of RelyX Ceramic Primer (RCP, groups 5 to 8) were applied and dried for 60 s. Brackets were bonded to the cylinders with Transbond XT and light-activated for 40 s with Bluephase G2. All specimens were stored in deionized water at 37 °C for 24 h, and the specimens of groups 1, 3, 5 and 7 were submitted to 7,000 thermal cycles (5 °C/55 °C). After storage, the SBS test was performed at a crosshead speed of 1 mm/min. Data were subjected to three-way ANOVA and Tukey's post hoc test (α=0.05). The adhesive remnant index (ARI) was evaluated at 8x magnification. The SBS of CCP was significantly greater than of RCP (p<0.05), with or without thermal cycling. Thermal cycling significantly reduced the SBS (p<0.05). The groups submitted to acid etching showed significantly higher SBS than those without acid etching (p<0.05). In conclusion, thermal cycling reduced SBS for all groups. The best ceramic surface treatment for bracket bonding was achieved by acid etching and CCP silane. The ARI results showed predominance of score 0 for all groups.

Objective:  the study is aimed to evaluate the effect of different surface treatment methods on shear bond strength between composite repair system and both of zirconia core and veneering porcelain and analyze the mode of failure between composite repair and ceramic surface. Material and methods: 40 Ceramic discs were fabricated with diameter of 7mm and 3mm thickness and divided according to material into two groups, Zirconia core discs (n = 20) and veneering porcelain discs (n = 20). Specimens were thermocycled and then each group was subdivided according to surface treatment method into 4 equal sub groups (n = 5) ,control subgroup I air abrasion, subgroup II Cojet, subgroup III laser, subgroup IV combination of air abrasion and laser surface treatment. Composite blocks were built up and polymerized on the surface of the specimens and shear bond strength of composite to each specimen was tested using a universal testing machine and mode of failure was evaluated using stereomicroscope. Results: Regardless of ceramic type; there was a statistically significant difference between surface treatments. Cojet recorded the highest mean shear bond strength. Laser showed the highest prevalence of adhesive failure.  Porcelain + Cojet showed the highest prevalence of cohesive failure. Conclusion: Cojet surface treatment provided superior shear bond strength regardless of the ceramic type whether zirconia or porcelain. Porcelain provided superior shear bond strength values in comparison to zirconia regardless of the surface treatment method tested. Porcelain showed higher percentage of cohesive failure that while the mode of failure in zirconia was most commonly adhesive.KEYWORDS Laser; Porcelain repair; Zirconia repair.

SUMMARYObjectives: To compare the effects of airborne-particle abrasion (APA) and tribochemical silica coating (TSC) surface treatment methods on the shear bond strength of zirconia ceramics systems, resin cements and tooth surfaceMaterials and Methods: Prefabricated Cercon and ZirkonZahn specimens treated with Al2O3 APA and TSC (Cojet, 3M ESPE) were luted on a dentin surface with Panavia F 2.0 (Kuraray, Japan) and Multilink Automix (Ivoclar Vivadent, Liechstein). The specimens were immersed in distilled water (37°C) for 30 days and then loaded in a universal test machine with a crosshead speed of 1 mm/min. Shear bond strength at failure was measured and recorded in N. The data were analysed by Mann-Whitney-U test (p<0.005) and by Chi-square test.Results: It’s demonstrated that the surface treatment affected the bond strength of all specimens. The mean bond strength values of the 2 zirconia systems were nearly the same. Shear bond strength of Cercon specimens treated with Cojet System, luted with Panavia 2.0 (242, 77 ± 53, 17 N were found to be significantly higher (p=0.04) than the other specimens. Fractures were observed at the interface between the ceramic surface and the cements or within the cements.Conclusion: There were no statically significant differences between zirconium systems (Cercon and Zirkonzahn). The specimens luted with Panavia F 2.0 showed higher shear bond strength values than the specimens luted with Multilink Automix. Panavia F 2.0 cement could be used with TSC, when the additive retention was needed.

Aim: The study aimed to evaluate and compare the effect of different surface treatment and thermocycling on the shear bond strength (SBS) of different dual-/light-cure cements bonding porcelain laminate veneers (PLV). Methods: One hundred and twenty A2 shade lithium disilicate discs were divided into three groups based on the resin cement used and on the pretreatment received and then divided into two subgroups: thermocycling and control. The surface treatment were either micro-etched with aluminium trioxide and 10% hydrofluoric acid or etched with 10% hydrofluoric acid only before cementation. Three dual-cure (Variolink Esthetic (I), RelyX Ultimate (II), and RelyX Unicem (III)) and three light-cure (Variolink Veneer (IV), Variolink Esthetic (V), RelyX Veneer (VI)) resin cements were used for cementation. The SBS of the samples was evaluated and analysed using three -way ANOVA with statistical significant set at α=0.05. Results: For all resin cements tested with different surface treatments, there was a statistically significant difference within resin cements per surface treatment (p<0.05). The shear bond strength in the micro-etch group was significant higher than the acid-etch group (p<0.05) There was statistically significant interaction observed between the surface treatment and thermocycling (p<0.05) as well as the cement and thermocycling(p<0.05). It was observed that the reduction in shear bond strength after thermocycling was more pronounced in the acid etch subgroup as compared to the microetch subgroup. However, the interaction between the three factors: surface treatments, thermocycling and resin cements did not demonstrate statistically significant differences between and within groups (p=0.087). Conclusions: Within the limitations of the present study, it acan be concluded that Dual cure resin cements showed a higher Shear bond strength as compared to light cure resin cements. Thermal cycling significantly decreased the shear bond strength for both ceramic surface treatments. After thermocycling, the specimens with 10% HF surface treatment showed lower shear bond strength values when compared to those treated by sandblasting with Al2O3 particles.

The aim of this study is to assess the shear security quality of two intra oral clay fix frameworks on metal substrate and fired substrate and to contrast among gatherings with evaluate a superior earthenware fix framework after corrosive scratching and laser surface treatment. Therefore, 40 Nickel chromium and 40 feldspathic ceramic specimens were fabricated and divided into two main groups which were further subdivided into four subgroups based on the repair systems used and surface treatments, which had ten specimens each. Hydrofluoric acid and Erbium-doped Yttrium aluminum garnet laser were used as surface treatments and two intra oral repair systems used were Bisco and Angelus. Bonded specimens were stored in distilled water for 24 hours before being thermocycled at 5°C to 55°C for 300 cycles with a 30-second dwell time. The specimens were stored for an additional 7 days before being subjected to shear force in a universal testing machine with a 10KN load cell at a crosshead speed of 0.5 mm/min. The bond strength values obtained were recorded in MPa and analyzed using independent t test. The outcomes indicate that the shear bond strength values obtained were highly significant for Bisco when compared to Angelus for both the metal and ceramic substrates. Similarly, after acid etching and laser surface treatment, Bisco proved to be better. At the end, Bisco repair system had significantly higher shear bond strength values when compared to Angelus. Hence it is the preferred choice for intraoral repair of fractured metal ceramic restorations. Er: YAG laser surface treatment is the recommended surface treatment for intraoral repair.
