“…A study with AFM images of the IPS Empress 2 presented results similar to ours, showing surface irregularities with peaks and valleys after the acid etching with HF acid 5% 43 . Similar results were found in others studies 12,41,42 ,using AFM images showing higher peaks and deeper valleys after HF acid etching at 10% during 20s, what may have increased the rougness of the IPS e.max CAD.…”

“…For restorations with glass-ceramic and success bonding with composite resin cements, the use of hydrofluoridric acid (HF) etching is recommended 30,31 . HF modifies the ceramic surface, because the acid removes the glassy matrix, exposes crystalline structure 12,32 , increases the roughness 11 and surface energy 13 in acidsensitive ceramics, as lithium disilicate 33 , forming hexafluorosilicates 34 .…”

“…Hydrofluoridric acid modifies the material surface, causing roughness and microporosities which increase the adhesion surface area, favoring silane retention, increasing the surface wettability and surface energy [10][11][12][13][14] .…”

“…An effective way to analyze qualitatively the effects of hydrofluoridric acid etching and silane coating on the ceramic surface is the use of Atomic Force Microscopy (AFM) and Optical Microscopy (OM). AFM has already been used in Dentistry in several studies 12,[20][21][22][23] . The microscope analyzes the specimen using a ceramic piezoelectric positioning system that moves on the three main axes (x, y, z) building 3D images under angstrom precision 24 .…”

“…According to the manufacturer, these novel material reduces the toxic potential of the HF, the chair-time required and the technique sensitivity of etching ceramic when compared to the conventional methods (9). It was shown that the selfetching ceramic primer promotes less-pronounced etching pattern than that produced by the two-step procedure involving hydrofluoric acid and silane (10,11).…”

To evaluate the effect of combining 5% hydrofluoric acid (HF) and silane (SI) with the selfetching ceramic primer on the immediate and after 1-year of water storage on bonding efficacy, conditioning pattern (CP) and chemical interaction (CI) to the lithium disilicate. A total of 16 CAD/CAM blocks of lithium disilicate (LD) were cut into four square sections (n=64). For bonding efficacy evaluation, the LD specimens were divided into 4 groups (n=10): 1) HF+SI; 2) self-etching ceramic primer (MEP); 3) HF+MEP; 4) MEP+SI. After each treatment, an adhesive system was applied and Tygon matrices were filled with a dualcured resin cement followed by light curing. Cylinder specimens (0.8 mm∅x0.5mm) were stored in water (37 °C for 24 h or 1-year) and submitted to the μSBS test (2-way ANOVA and Tukey's test; α=0.05). CP and CI were only evaluated qualitatively. No significant difference on the μSBS was observed between groups (p=0.73), but reduced μSBS was observed after 1-year of water storage (p>0.0001). After application of HF+SI and MEP, reduction in a number of siloxane bonds was observed, suggesting the coupling of SI on the LD surface. HF or HF+MEP produced a higher dissolution of the glassy matrix than the use of MEP alone. The MEP can be an alternative to traditional ceramic treatment once the chemical interaction and long-term bond strength were similar between both groups. The association of hydrofluoric acid or silane with a self-etching ceramic primer did not add any benefits in terms of chemical interaction and bonding stability.

Objective: This study examined the influence of surface contamination during repair procedures with hydrofluoric acid, silane, or ammonium polyfluoride on the bond strength of universal adhesives to dentin using different etching modes before and after thermocycling.Materials and Methods: Dentin surfaces of human molars were contaminated in different ways (silane, hydrofluoric acid, ammonium polyfluoride, and no pretreatment as control) followed by application of a universal adhesive (etch & rinse or self-etch mode).After a composite build-up was placed onto each tooth, sticks for the microtensile bond strength (MTBS) test were sectioned. Half of the sticks were tested after water storage for 24 h, the other half after thermocycling (15,000 cycles, 5/55°C). The MTBS data were analyzed statistically by using the Kolmogorov-Smirnov test, one-way analysis of variance, and Tukey HSD test (p < 0.05). The fracture patterns of all specimens were evaluated and analyzed using a χ 2 test.Results: Dentin contamination with a multifunctional silane does not influence microtensile bond strength irrespective of aging. Contamination with hydrofluoric acid or an ammonium polyfluoride primer leads to a significantly lower bond strength after aging, irrespective of the etch mode. Conclusion:Dentin contamination with hydrofluoric acid or ammonium polyfluorides during repair procedures should be avoided, as they appear to decrease the bond strength of universal adhesives.

Self-etching ceramic primer versus hydrofluoric acid etching: Etching efficacy and bonding performance

Abstract: Under limited conditions, using MEP resulted in comparable SBS results to HFMP; meanwhile HFMP remains the gold standard for pretreatment of glass ceramics for resin-luting cementation.
