The effect of different etching times of acidulated phosphate fluoride gel on the shear bond strength of high-leucite ceramics bonded to composite resin

Boonlert Kukiattrakoon; Kewalin Thammasitboon

STATEMENT OF PROBLEM A 10-minute treatment with acidulated phosphate fluoride (APF) gel has been used as an alternative in ceramic surface etching before repairing with composite resin. However, the optimal etching time for APF gel is still unknown. PURPOSE The purpose of this study was to determine the in vitro shear bond strengths of composite resin on high-leucite ceramics after APF gel treatment over different time periods. MATERIAL AND METHODS One hundred and twenty high-leucite ceramic (Empress 1) specimens (12 mm in diameter and 1.5 mm thick) were prepared and divided into 12 groups (n=10). Ten experimental groups were surface treated with 1.23% APF gel, each group receiving 1 to 10 minutes of etching time in 1 minute increments. One group was treated with 9.6% hydrofluoric acid for 4 minutes and the final group received no treatment and served as a control. The surface condition of the treated specimens was analyzed under a scanning electron microscope (SEM). All specimens received a silane application and were bonded to a composite resin Filtek (Z250) cylinder with an adhesive system (Scotchbond Multi-Purpose Plus adhesive) and then stored in 100% humidity at 37 degrees C for 24 hours before shear bond strength testing in a universal testing machine. Mean bond strengths (MPa) were analyzed with 1-way ANOVA and the Tukey HSD test (alpha=.05). RESULTS Hydrofluoric acid etching produced the highest mean shear bond strength (SD) between composite resin and the ceramic (17.64 (1.48) MPa). Overall, APF gel etching produced lower bond strengths. No significant difference in mean bond strength (SD) was observed between etching with hydrofluoric acid and etching with APF gel for 7 to 10 minutes (15.21 (1.93) to 17.33 (1.43)). The lowest mean shear bond strengths (SD) were recorded in the untreated group (7.61 (1.03) MPa) (P<.05). CONCLUSIONS Within the limitations of this study, shear bond strength values between composite resin and high-leucite ceramics after etching with 1.23% APF gel for 7 to 10 minutes were not significantly different than that after etching with 9.6% hydrofluoric acid for 4 minutes.

Boonlert Kukiattrakoon; Chanothai Hengtrakool; Ureporn Kedjarune-Leggat

STATEMENT OF PROBLEM Acidic food and sour fruits and drinks have been investigated for their destructive effects on enamel. However, their effect on porcelain restorations has not been widely examined. PURPOSE The purpose of this study was to evaluate the ion leaching of porcelains immersed in acidic agents. MATERIAL AND METHODS Fifty-five discs (12.0 mm in diameter and 2.0 mm in thickness) were made from each of 4 types of porcelain (VITA VMK 95, Vitadur Alpha, IPS Empress Esthetic, and IPS e.max Ceram). Baseline data of elemental compositions of all storage agents were recorded. Four groups of discs (n=10) were then immersed in acidic agents (citrate buffer solution, pineapple juice, and green mango juice) and deionized water (control) at 37 degrees C for 168 hours. One group was immersed in 4% acetic acid at 80 degrees C for 168 hours. After immersion, fluids from all specimens for each acidic agent were measured for ion leaching with an inductively coupled plasma optical emission spectroscopy. Surface characteristics of specimens were examined using scanning electron microscopy (SEM). Data were analyzed using 3-way repeated ANOVA and Tukey HSD multiple comparisons (alpha=.05). RESULTS This study revealed that each type of porcelain had significantly leached the various ions to varying degrees after being immersed in acidic agents (P<.001 for all comparisons). SEM photomicrographs showed surface destruction of all porcelains. CONCLUSIONS Acidic agents used in this study affected elemental dissolution of the 4 types of porcelains evaluated.

Boonlert Kukiattrakoon; Chanothai Hengtrakool; Ureporn Kedjarune-Leggat

Abstract Objective. To evaluate the microhardness and surface elemental compositions of ceramics immersed in acidic agents. Material and methods. Thirty-five ceramic disc specimens were made from each of four types of ceramic (VMK 95, Vitadur Alpha, Empress Esthetic and IPS e.max Ceram). Before immersion, baseline data of Vickers microhardness and elemental composition were recorded. Four groups of discs (seven per group) were then immersed in acidic agents (citrate buffer solution, pineapple juice and green mango juice) and deionized water (as a control) for 168 h at 37°C. One group was immersed in 4% acetic acid at 80°C for 168 h. After immersion, specimens were evaluated and data were analyzed using two-way ANOVA with repeated measurements and a paired t-test at a significance level of 0.05. Results. The microhardness values of four types of ceramic significantly decreased after being immersed in acidic agents (p < 0.05). The elemental compositions of ceramics mainly comprise silicon, aluminium and potassium. These compositions also decreased after immersion (p < 0.05). Conclusions. The acidic agents used in this study affected the microhardness and elemental dissolution of ceramics. The main elemental compositions of ceramics (silicon, aluminium and potassium) decreased after being immersed in acidic agents.

Aims: To determine the in vitro shear bond strengths (SBS) of zirconia ceramic to resin composite after various primer treatments. Materials and Methods: Forty zirconia ceramic (Zeno, Wieland Dental) specimens (10 mm in diameter and 2 mm thick) were prepared, sandblasted with 50 μm alumina, and divided into four groups (n = 10). Three experimental groups were surface treated with three primers; CP (RelyX Ceramic Primer, 3M ESPE), AP (Alloy Primer, Kuraray Medical), and MP (Monobond Plus, Ivoclar Vivadent AG). One group was not treated and served as the control. All specimens were bonded to a resin composite (Filtek Supreme XT, 3M ESPE) cylinder with an adhesive system (Adper Scotchbond Multi-Purpose Plus Adhesive, 3M ESPE) and then stored in 100% humidity at 37°C for 24 h before SBS testing in a universal testing machine. Mean SBS (MPa) were analyzed with one-way analysis of variance (ANOVA) and the Tukeys Honestly Significant Difference (HSD) test (α = 0.05). Results: Group AP yielded the highest mean and standard deviation (SD) value of SBS (16.8 ± 2.5 MPa) and Group C presented the lowest mean and SD value (15.4 ± 1.6 MPa). The SBS did not differ significantly among the groups (P = 0.079). Conclusions: Within the limitations of this study, the SBS values between zirconia ceramic to resin composite using various primers and untreated surface were not significantly different.

Aims: To investigate the effects of five beverages (apple cider, orange juice, Coca-Cola, coffee, and beer) on microhardness and surface characteristic changes of nanohybrid resin composite and giomer. Materials and Methods: Ninety-three specimens of each resin composite and giomer were prepared. Before immersion, baseline data of Vickers microhardness was recorded and surface characteristics were examined using scanning electron microscopy (SEM). Five groups of discs (n = 18) were alternately immersed in 25 mL of each beverage for 5 s and in 25 mL of artificial saliva for 5 s for 10 cycles. Specimens were then stored in artificial saliva for 24 h. This process was repeated for 28 days. After immersion, specimens were evaluated and data were analyzed by two-way repeated analysis of variance (ANOVA), Tukeys honestly significant difference (HSD), and a t-test (α = 0.05). Results: Microhardness of all groups significantly decreased after being immersed in the tested beverages (P < 0.05). SEM photomicrographs presented surface degradation of all groups. Conclusions: The effect of these beverages on the surface of both restorative materials also depended upon the exposure time and chemical composition of the restorative materials and beverages.

Objective The aim of this study was to evaluate the flexural strength of two porcelain materials (IPS d.SIGN and IPS e.max Ceram) exposed to erosive agents Material and Methods One hundred and twenty bar-shaped specimens were made from each of fluorapatite-leucite porcelain (IPS d.SIGN) and fluorapatite porcelain (IPS e.max Ceram) and divided into 8 groups of 15 specimens each. Six groups were alternately immersed in the following storage agents for 30 min: deionized water (control), citrate buffer solution, pineapple juice, green mango juice, cola soft drink and 4% acetic acid. Then, they were immersed for 5 min in deionized water at 37°C. Seven cycles were completed, totalizing 245 min. A 7th group was continuously immersed in 4% acetic acid at 80°C for 16 h. The final, 8th, group was stored dry at 37°C for 245 min. Three-point bending tests were performed in a universal testing machine. The data were analyzed statistically by 2-way ANOVA, Tukey’s HSD test and t-test at significance level of 0.05. Results The flexural strengths of all groups of each porcelain after exposure to erosive agents in cyclic immersion did not differ significantly (p>0.05). For both types of porcelain, dry storage at 37°C yielded the highest flexural strength, though without significant difference from the other groups (p>0.05). The flexural strengths of all groups of fluorapatite porcelains were significantly higher (p<0.05) than those of the fluorapatite-leucite porcelains. Conclusions This study demonstrated that the erosive agents evaluated did not affect the flexural strength of the tested dental porcelains.

Aims: To investigate surface microhardness of nanocomposites after cyclic immersion in red and white wines. Materials and Methods: Seventy-two specimens of each resin composite were prepared. Before immersion, baseline data of Vicker′s microhardness were recorded and surface characteristics were examined using scanning electron microscopy (SEM). Three groups of discs (N = 23) were then alternately immersed in red wine, white wine, and deionized water (as a control) for 25 min and artificial saliva for 5 min over four cycles. The specimens were then stored in artificial saliva for 22 h. This process was repeated for 5 days following immersion in artificial saliva for 2 days. Subsequently, the process was repeated. After immersion, specimens were evaluated and data were analyzed by two-way repeated analysis of variance (ANOVA) and Tukey′s honest significant difference (HSD) (α = 0.05). Results: Microhardness values significantly decreased after being immersed in the red and white wines (P < 0.05). SEM photomicrographs presented surface degradation of all groups after immersion in red and white wines. Conclusion: The effect of red and white wines on surface microhardness of nanocomposite restorative materials depended on the physical and chemical compositions of the materials and the types of wine.

Aims: This study aimed to investigate the effects of red and white wine on the surface roughness and erosion of nanohybrid and nanofilled resin composites. Materials and Methods: Sixty specimens of each resin-based composite (RBC) were prepared. Before immersion, baseline data roughness values were recorded using a profilometer. Three groups of discs (n = 20) were then alternately immersed in red wine, white wine, and deionized water (as a control) for 25 min and artificial saliva for 5 min over four cycles. The specimens were then stored in artificial saliva for 22 h. This process was repeated for 5 days following immersion in artificial saliva for 2 days. Subsequently, the process was repeated. After immersion, the specimens were evaluated and data were analyzed by two-way repeated analysis of variance (ANOVA) and Tukey′s honestly significant difference (HSD) (α = 0.05). Results: Red wine caused significantly greater roughness and erosion than did white wine and deionized water (P < 0.05). Nanohybrid resin composites were significantly rougher than nanofilled resin composites (P < 0.05). Conclusion: The effects of red and white wine on the surface roughness and erosion of resin composite restorative materials depended upon the physical and chemical composition of the restorative materials and the types of wine.

Sasiwimol Sanohkan; Boonlert Kukiattrakoon; Chaimongkon Peampring

Aim: To evaluate the tensile bond strength between Silastic MDX 4-4210 silicone and autopolymerizing acrylic resin (Orthojet) with two facial silicone primers (A306 and A330-G) and three primers used for silicone-based intraoral reliner materials [Sofreliner tough primer (ST); Mucosoft bond liner primer (ML); and Mucopren adhesive (MA)]. Materials and Methods: Sixty specimens were divided into six groups according to the primers used to attach the facial silicone to the acrylic resin. All specimens were loaded in tension mode in a universal testing machine with a crosshead speed of 10 mm/min until bonding failure occurred. Results: The highest bond strength values were found in the ST group (1.42 ± 0.24 MPa) followed by the MA group (1.39 ± 0.20 MPa) and the ML group (1.32 ± 0.24 MPa), which were significantly different from the A330-G group (1.12 ± 0.10 MPa), A306 group (0.69 ± 0.0.11 MPa), and the control group (0.18 ± 0.08 MPa). The mode of failure for all specimens was found to be adhesive failure at the facial silicone and bonding agent interface. Conclusion: This study suggests that silicone-based intraoral reliner materials can be used as facial silicone primers.
