Abstract

Background and Aims: The aim of this study was to evaluate the quality of an experimental hydrofluoric acid (HF) for preparation of porcelain and to compare it with two commercial hydrofluoric acids in Iranian trademark.Materials and Methods: A- Evaluation of etch pattern of experimental HF using scanning electron microscope (SEM): 6 feldespathic discs were divided into 3 groups. Each group was etched with related HF (experimental, Ultradent and Kimia) for 1 minute. SEM images were recorded at 3 magnifications. B- BOND STRENGTH test: 18 feldespathic discs were considered for each acidic group. Then the porcelain surfaces were etched and bonded to composite with unfilled resin. Consequently, the microshear test was done. C- MICROLEAKAGE test: 54 discs were divided into 3 groups (n=18). Then the porcelain surfaces were etched and bonded to composite with unfilled resin and finally observed under stereomicroscope. The data were analyzed with one-way ANOVA and Smirnov tests.Results: SEM analysis showed no difference between groups in terms of etch pattern. Microshear BOND STRENGTH values for experimental, Kimia, and Ultradent HF were 28.53 (±4.92), 28.21 (±6.61), and 26.14 (±7.61) MPa, respectively. There was no significant difference between the BOND STRENGTH of test groups (P<0.05). Furthermore, no significant difference was found between the MICROLEAKAGE of test groups (P>0.05).Conclusion: Quality of experimental HF in terms of etch pattern, microshear BOND STRENGTH and MICROLEAKAGE of composite/porcelain interface was similar to that of two commercial hydrofluoric acids.
