Materials and Methods: Forty-eight human dentin samples were assigned to three different treatment modalities: I: Plasma jet irradiation (CAP I); II: Dielectric barrier discharge plasma treatment (CAP II); and III: No plasma (control). In each group, half of the specimens had previously been demineralized. A fourth generation of adhesive and dental composite was applied to all of the samples. The testing of the TBS was performed after artificial aging. Results: In the non-demineralized dentin, the mean TBS values were significantly higher after using CAP II (16.95 MPa) than in the control samples (4.2 MPa; p = 0.001). Significantly higher TBS values were also obtained after irradiating the demineralized dentin with CAP I and CAP II (11.68 and 4.6 MPa) when compared to the control samples (0 MPa; p = 0.003 and 0.038). The differences between both of the plasma sources were only slightly significant (p = 0.05). Conclusion: CAPs can potentially enhance the adhesive/dentin interfacial bonding strength, whereby the underlying effects seem to depend on the type of plasma source and the degree of dentinal (de-) mineralization. In the non-demineralized dentin, after a complete caries excavation, dielectric barrier discharge devices might be favorable over the plasma jets, in order to improve the adhesive/dentin interfacial bonding. In contrast, the plasma jets could be more effective in the demineralized dentin after an incomplete caries excavation. 11 28 2018 960 968 TODENTJ-12-960 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2018-3-29 2018-10-4 2018-10-21 2018-11-28 https://creativecommons.org/licenses/by/4.0/legalcode 10.2174/1874210601812010960 1553507616 https://opendentistryjournal.com/VOLUME/12/PAGE/960/ https://opendentistryjournal.com/contents/volumes/V12/TODENTJ-12-960/TODENTJ-12-960.pdf https://opendentistryjournal.com/contents/volumes/V12/TODENTJ-12-960/TODENTJ-12-960.pdf https://opendentistryjournal.com/contents/volumes/V12/TODENTJ-12-960/TODENTJ-12-960.pdf https://opendentistryjournal.com/contents/volumes/V12/TODENTJ-12-960/TODENTJ-12-960.pdf https://opendentistryjournal.com/contents/volumes/V12/TODENTJ-12-960/TODENTJ-12-960.pdf https://opendentistryjournal.com/contents/volumes/V12/TODENTJ-12-960/TODENTJ-12-960.pdf https://opendentistryjournal.com/contents/volumes/V12/TODENTJ-12-960/TODENTJ-12-960.pdf https://opendentistryjournal.com/contents/volumes/V12/TODENTJ-12-960/TODENTJ-12-960.xml Micron Bertassoni L.E. 43 1364 2012 10.1016/j.micron.2012.03.021 Bertassoni LE, Marshall GW, Swain MV.
