“…However, our results found that both APP and UV treatments to ceramic surface kept hydrophilicity the same as the phosphoric acid-treated control (p > 0.05). Similarly to our results, Han et al [35] reported that the contact angles of deionized water to APP-treated feldspathic porcelain (VITABLOCS Mark II, lower than 10 • ) were lower than ground surface (15.9 ± 3.8 • ).…”

“…According to some XPS (X-ray Photoelectron Spectroscopy) study, APP-treated ceramic surface showed that the content of C-C bonds decreased, suggesting that organic matter was removed. By contrast, the content of oxygen-containing polar groups increased (C-O-C and O=C-O), suggesting that APP treatment enhanced the surface hydrophilicity [32,35,36].…”

“…Therefore, the second null hypothesis, that pre-treating CAD/CAM glass ceramic with APP or UV would not improve the repair bond strengths, was also accepted. Han et al [35] also reported that the shear bond strength to APP-treated ceramic was lower than the ceramic treated with the gold-standard hydrofluoric acid-etching and silane coupling agent [24]. According to some XPS (X-ray Photoelectron Spectroscopy) study, APP-treated ceramic surface showed that the content of C-C bonds decreased, suggesting that organic matter was removed.…”

Abstract:The aim of this study was to investigate whether atmospheric-pressure plasma (APP) or ultraviolet (UV) irradiation could alter the hydrophilicity of a computer-aided design/computer-aided manufacturing (CAD/CAM) glass ceramic surface, and thereby enhance the repair bond strength between the ceramic and a resin composite. Forty-eight leucite-reinforced glass ceramic discs were treated with 40% phosphoric acid and randomly assigned into one of six groups: Group 1, control; Group 2, treated with a mixture of Clearfil SE Bond primer (SEP) and Clearfil Porcelain Bond Activator (PBA); Group 3, subjected to APP irradiation for 10 s; Group 4, subjected to UV irradiation for 60 min; Group 5, APP irradiation followed by SEP/PBA; and Group 6, UV irradiation followed by SEP/PBA. After treatment, discs were bonded with resin composite using Clearfil SE Bond and stored in water at 37 • C for 1 week. We then tested how these treatments affected the microtensile bond strength (µTBS) and measured changes in the water contact angle (CA). Samples from Group 2 showed the highest µTBS (44.3 ± 6.0 MPa) and CA (33.8 ± 2.3 • ), with no significant differences measured between Groups 1, 3, and 4 (p < 0.05). Furthermore, the additional treatments of APP or UV before SEP/PBA had no effect (Group 5, p = 0.229) or a reduced effect (Group 6, p = 0.006), respectively, on µTBS. Overall, APP or UV irradiation before SEP/PBA treatment did not enhance the repair bond strength.

Nonthermal Atmospheric Plasmas in Dental Restoration

It is well known that the service life of contemporary composite restoration is unsatisfactory, and longevity of dentin bonding is one of the major culprits. Bonding is essentially a hybridization process in which dental substrate and adhesive resin interact with each other through an exchange process. Thus, the longevity of dentin bonding can only be improved with enhanced qualities in substrate, adhesive resin, and their interaction within the hybridization zone. This review aims to collect and summarize recent advances in utilizing nonthermal atmospheric plasmas (NTAPs)-a novel technology that delivers highly reactive species in a gaseous medium at or below physiologic temperature-to improve the durability of dentin bonding by addressing these 3 issues simultaneously. Overall, NTAP has demonstrated efficacies in improving a number of critical properties for dentin bonding, including deactivation of oral pathogens, modification of surface chemistry/properties, resin polymerization, improvement in adhesive-dentin interactions, and establishment of auxiliary bonding mechanism. While a few preliminary studies have indicated the benefit of NTAP to bond strength and stability, additional researches are warranted to employ knowledge acquired so far and to evaluate these properties in a systematic way.

Quantitative Evaluation of Contamination on Dental Zirconia Ceramic by Silicone Disclosing Agents after Different Cleaning Procedures

et al. 2015

The aim of this study was to evaluate the effectiveness of cleaning procedures for air-abraded zirconia after contamination with two silicone disclosing agents. Air-abraded zirconia ceramic specimens (IPS e.max ZirCAD) were contaminated with either GC Fit Checker white or GC Fit Checker II. Untreated zirconia specimens were used as control. Afterwards the surfaces were cleaned either with waterspray or ultrasonically in 99% isopropanol or using a newly developed cleaning paste (Ivoclean). After cleaning X-ray photoelectron spectroscopy (XPS) was performed and the relative peak intensities of Zr, C and Si were used for a qualitative comparison of the residuals. There was no significant difference between the two different silicone disclosing agents. An additional cleaning step with isopropanol led to a significantly lower amount of residuals on the surface, but an additional cleaning process with Ivoclean did not reduce the amount of carbon residuals in comparison to the isopropanol cleaning. Just the silicone amount on the surface was reduced. None of the investigated cleaning processes removed all residuals from the contaminated surface. Standard cleaning processes do not remove all residuals of the silicone disclosing agent from the surface. This may lead to a failure of the resin-ceramic bonding.
