“…Contradictory to our findings, Balkenhol et al (23) mentioned that SBS with plasma surface treatment resulted in unpredictable outcomes explaining that with integration of oxygen on surface with humidity which will inhibit the resin polymerization and supported this with spectral investigation showing OH content increase with H 2 O on zirconia surface. Regarding sandblasting, it was considered as the most clinically applicable method for improving zirconia bond strength to adhesive resin with its simplicity.…”

“…The most appropriate test for the present study was shear bond strength test (SBST) to measure the influence of the surface treatment on the changes in adhesive bond with zirconia surface (25) . This can be explained as it's well-known that tensile bond strength tests were greatly affected by the strength of the ceramic itself and not by the true adhesive bond with the resin cement (23) . Moreover, the cohesive failure within zirconia has never been reported (26) .…”

Purpose:The purpose of the present study was to analyze the effect of non-thermal air plasma treatment on shear bond strength and failure mode of self-adhesive resin cement to zirconia.Materials& Methods: Forty eight zirconia plates were prepared from IPS e.max ZirCad blocks (Ivoclar Vivadent, Schaan, Liechtenstein) and classified into four groups (n=12) according to surface treatment; group CO (control) without any surface treatment, group SD was treated with 50 µm alumina sandblasting, group PL used air atmospheric pressure plasma device (Piezobrush® PZ2, Relyon plasma GMBH, Regensburg, Germany) & group SP which was a combination of 50 µm alumina sandblasting followed immediately with atmospheric plasma treatment. Zirconia specimens were immediately centered with Relay X Unicem (3M ESPE) resin cylinders of 3.7 mm diameter and 2 mm height. Shear bond strength test was performed 8 days after water storage at 37˚C using a computer controlled materials testing machine (Model 3345; Instron Industrial Products, Norwood, USA). A scanning electron microscope (Quanta 250 Field Emission Gun, Netherlands) was used to determine failure mode with all morphological and structural changes. Average surface roughness (Ra) was calculated with different surface treatments. Energy Dispersive X-ray (EDX) analysis was used for chemical changes evaluation. Data were analyzed with one-way ANOVA followed by Tukey's post hoc test when the ANOVA test was significant.Results: A significant difference between different surface treatments (P=0.010) was recorded with the highest shear bond strength value in SP group and the lowest value with untreated surface CO gp. All groups showed mixed failure mode which was mainly cohesive except for CO gp. Surface roughness was increased with sandblasting and decreased after plazma treatment. EDX analysis showed increase oxygen on plazma treated surface. Conclusion:Non thermal air plasma treatment can be used for increasing zirconia surface treatment especially when accompanied with 50 µm AL 2 O 3 sandblasting.Clinical significant: Non thermal air plasma treatment alone or in combination with sandblasting can be considered as a good clinical protocol for cementing zirconia restorations.

“…In lately reported studies, lots of surface treatments have been conducted to enhance the adhesion between zirconia and veneering ceramic [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. For instance, the surface roughness of zirconia can be increased by particle abrasion, formation of surface holes by CNC, and laser irradiation using different types of dental lasers and energy intensities [ 15 , 16 , 17 , 18 ].…”

“…For instance, the surface roughness of zirconia can be increased by particle abrasion, formation of surface holes by CNC, and laser irradiation using different types of dental lasers and energy intensities [ 15 , 16 , 17 , 18 ]. Also, hydrophilic functionality can be offered by using phosphate monomer, and surface energy level can be increased by the cold atmospheric plasma [ 19 ]. Chemical bonding can be induced by various kinds of liner treatments and selective infiltration etching (SIE) [ 15 , 20 , 21 , 22 ].…”

This study was performed to evaluate the effect of a lithium-disilicate spray-liner application on both the bond strength between zirconia cores and heat-pressed lithium-disilicate glass-ceramic veneers, and the fracture strength of all-ceramic zirconia crowns. A lithium-disilicate reinforced liner was applied on the surface of a zirconia core and lithium-disilicate glass-ceramic was veneered on zirconia through heat press forming. Microtensile and crown fracture tests were conducted in order to evaluate, respectively, the bonding strength between the zirconia cores and heat pressed lithium-disilicate glass-ceramic veneers, and the fracture strength of bilayered zirconia all-ceramic crowns. The role of lithium-disilicate spray-liner at the interface between zirconia and lithium-disilicate glass-ceramic veneers was investigated through surface and cross-sectional analyses. We confirmed that both the mean bonding strength between the zirconia ceramics and lithium-disilicate glass-ceramic veneers and the fracture strength of the liner-treated groups were significantly higher than those of the untreated groups, which resulted, on the one hand, from the chemical bonding at the interface of the zirconia and lithium-disilicate liner, and, on the other, from the existence of a microgap in the group not treated with liner.

“…The plasma treatment for oral materials is mainly manifested in two aspects. The first aspect is the surface modification of the dental materials, mainly related to oral implant materials and adhesive materials [84, 94–96]. The second one is the disinfection of the oral materials, mainly used in the oral medicine materials and restorative materials [97].…”

In recent years, translational plasma medicine (TPM), as a novel application area of plasmas, has attracted much attention of experts from both academic and clinical fields. State-of-the-art of the lab-scale research and clinical trials of the cold atmospheric plasmas (CAPs) in the stomatology are reviewed in detail from the direct and indirect applications of the CAPs. Based on the discussions concerning the relationship between the plasma stomatology and the plasma medicine, it is indicated that it would be an important reference for promoting the TPM starting from the fundamental and application studies in the field of dentistry, which is also one of the most three promising application fields of plasma medicine.
