The effect of different cleaning agents and resin cement materials on the bond strength of contaminated zirconia

Abstract

The purpose of this study was to examine the effect of different cleaning methods and resin cements on the shear bond strength (SBS) of contaminated zirconia. A total of 92 disc-shaped zirconia specimens were contaminated with different procedures.Then, the specimens were grouped according to cleaning methods and resin cements: no cleaning + Variolink Esthetic DC (CN V ), no cleaning + Panavia V5 (CN P ), sandblasted + Variolink Esthetic DC (SB V ), sandblasted + Panavia V5 (SB P ), Ivoclean + Variolink Esthetic DC (IC V ), Ivoclean + Panavia V5 (IC P ), Katana Cleaner + Variolink Esthetic DC (KC V ), and Katana Cleaner + Panavia V5 (KC P ). Following an aging protocol in a 37 C for 1 week, SBS analysis was performed with a universal test machine. For the surface topography and elemental analysis, scanning electron microscopy and energy-dispersive X-ray spectroscopy (EDS) were used. Significance was evaluated as p < .05 and p < .01. The highest SBS results were found in the SB P group, showing a statistically significant difference from all other groups (p < .05). For the same cleaning method, Panavia V5 showed statistically significantly higher SBS values than Variolink Esthetic DC (p < .01), except the CN P -CN V (p = .880) and KC P -KC V (p = .082) groups. The most detected surface elements by EDS were Zr, O, C, and N, respectively. The contaminated zirconia surfaces must be cleaned for successful adhesion. The use of phosphate-containing adhesives in combination with sandblasting will increase the adhesion strength, and universal cleaning agents can be a good alternative to sandblasting.adhesive resin cement, alumina-blasting, contaminated zirconia, surface cleaning, universal cleaning paste | INTRODUCTIONThe increasing demand for esthetic restorations in dentistry has led to the development of all-ceramic materials with high esthetic and mechanical properties. Zirconia has become a promising material, with its high mechanical properties, ease of fabrication, low fabrication cost, biocompatibility, and strong esthetic properties (Denry &

“…Thereafter, the samples were cooled down to room temperature at a steady cooling rate of 9 °C/min. The zirconia ceramic surface was sandblasted for 10 s with a 50 µm alumina oxide particle at a 10 mm distance using 2.5 bar pressure and cleaned with 75% alcohol 36 .…”

The Computer Aided Design/press technique: Fabrication of zirconia‐reinforced lithium disilicate restorations for treatment of extensive noncarious cervical lesions

“…This cleaner has a pH value of 4.51 which allows for intraoral usage, facilitating the removal of temporary cement remnants and contaminants like blood or saliva in the abutment tooth surface. This is especially beneficial when self‐adhesive cement systems are used 11 . A silane coupling agent (Ceramic Primer Plus, Kuraray Noritake Dental) was applied to the intaglio surfaces of the restorations (Figure 12).…”

Effect of Dentin Contamination with Hemostatic Agents and Cleaning Techniques on Bonding with Self-Adhesive Resin Cement

“…Mechanical cleaning methods typically involve rotary instruments with pumice or ultrasonic scalers, while sandblasting with aluminum oxide is another approach [23]. Chlorhexidine, sodium hypochlorite, hydrogen peroxide, polyacrylic acid, phosphoric acid, and methacryloyloxydecyl dihydrogen phosphate (MDP) are widely used chemical cleaning agents [24].…”

“…Recently, KatanaTM Cleaner (Kuraray Noritake Dental, Inc., Okayama, Japan), a novel MDP salt cleaner, has emerged as a potential cleaning agent. This mild (pH 4.5) cleaner, composed of MDP (a phosphate monomer) and an alkaline compound, demonstrates efficacy in cleaning intraoral and extraoral tooth structures and restorations [24,[30][31][32][33]. Numerous studies have highlighted its effectiveness on zirconia surfaces [30][31][32][33][34].…”

“…Despite evidence suggesting Katana Cleaner's effectiveness in cleaning zirconia surfaces contaminated with saliva and blood [24,[30][31][32][33], its influence on self-adhesive resin cement SBS to dentin contaminated with hemostatic agents remains unknown. Therefore, this study aims to evaluate the SBS of self-adhesive resin cement applied after cleaning dentin contaminated with hemostatic agents using 4 different methods: water rinse, phosphoric acid, chlorhexidine, and Katana Cleaner.…”
