Effects of non-thermal atmospheric plasma treatment on dentin wetting and surface free energy for application of universal adhesives

Abstract

NTAP treatment of dentin prior to adhesive application increases dentin wetting and surface free energy facilitating better adhesive distribution on dentin surface compared to phosphoric acid etching and similar to the "self-etch" application protocol.

Effect of Diode Laser (810 nm) Irradiation on Marginal Microleakage of Multi-mode Adhesive Resins in Class V Composite Restorations

“…25 It is reported that rising temperature of the adhesive agent with a warm air stream, 16 the use of an electric current, 26 and also laser irradiation improves bonding resin infiltration into the tooth structure. 19,27,28 In this study, the effect of the 810 nm diode laser irradiation on marginal microleakage of universal bonding systems in class V composite restorations was evaluated. The results showed that the 810 nm diode laser irradiation on the unpolymerized universal adhesive, which was applied in a self-etch mode, significantly reduced the marginal microleakage of the composite restorations (P < 0.05).…”

Effects of alumina airborne-particle abrasion on the surface properties of CAD/CAM composites and bond strength to resin cement

“…Our results are compatible with other reports on the same and various other composites 18,28) . The SFE analysis is used to estimate the chemical state of a material surface 15,[31][32][33][34][35][36][37][38][39][40] . We reported that the SFE is strongly correlated to the microstructure of the CAD/CAM composite, affecting its adhesion to the resin cement in our previous report 15) .…”

Evaluation of the bond strengths of restorative materials to primary tooth dentin treated with different pulpotomy techniques

“…The application of APCP increases the wettability of the dentin surface by decreasing the water contact angle of the dentin (Stasic et al, 2019). In doing so, APCP promotes the penetration of hydrophilic monomers in the adhesive resin into the collagen network and dentinal tubules and also leads to the formation of a thicker hybrid layer, thereby generating a stronger micromechanical bond through the extension of resin tags into tubules (Dong et al, 2015; Han et al, 2014; Han, Kim, Cho, Hwang, & Kim, 2019; Hirata et al, 2015).…”

“…It has been reported that APCP forms a thicker hybrid layer by affecting the penetration of adhesive resins to dentinal tubules, thereby promoting the bonding of the material to the dentin, ultimately contributing to the long‐term success of the treatment (Dong et al, 2015; Han et al, 2014; Ritts et al, 2010; Stancampiano et al, 2019). Dong et al (2014) and Stancampiano et al (2019) showed that the application of APCP led to morphological changes on dentin surface while some other authors reported that APCP showed no significant change on dentin surface that could be observed by SEM (Chen et al, 2013; Stasic et al, 2019). The SEM evaluation of the present study revealed that no significant change observed in the morphology of dentin following the application of APCP when compared to the control group.…”
