Special Issue Information

Dear Colleagues,

It is well recognized that dental biomaterials are in a state of continuous evolution. Fundamental processes, such as biocompatibility, corrosion, and adhesion, depend on the biomaterial’s surface properties (chemistry, surface energy, morphology, hardness, roughness, etc.). There are several conventional techniques that can be used to assess these properties, and new tools have been developed so as to probe the surface at the nano-level. Thus, knowledge and control of the surface properties are essential for the long-term success of restorative procedures.

This Special Issue seeks papers related to recent developments in the field of the surface analysis of dental biomaterials. Topics of interest include, but are not limited to, ceramics, dental alloys, bioceramics, polymers, composites, 3D printing dental materials, and bio-inks.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Functional Biomaterials is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The objective of this study was an assessment of the anti-biofilm properties of fluoride non-thermal atmospheric plasma (FNTAP) generated using argon and hydrocarbon fluoride gas 1,1,1,2-tetrafluoroethane (TFE). These properties were evaluated by measuring the destruction and recovery of in vitro dual-species biofilms of Streptococcus mutans and Streptococcus sanguinis exposed to FNTAP at 5 or 10 standard cubic centimeters per minute (sccm) or argon non-thermal atmospheric plasma (ArNTAP) for 1 or 2 min, using resazurin-based reagent viability assays, colony forming units (CFU), culture media pH and live/dead staining. Both ArNTAP and FNTAP resulted in significant immediate reductions in bacterial load as compared to the control. Although ArNTAP did not significantly reduce biofilm regrowth, FNTAP treatment showed a bacterial load reduction of more than 5 log units of biofilm regrowth. FNTAP treatments significantly reduced the acidification of the culture medium after recovery incubation, indicating reduced living bacteria, with a pH of 6.92 ± 0.02 and 6.90 ± 0.03, respectively, for the 5 sccm and 10 sccm FNTAP treatments, as compared to a pH of 5.83 ± 0.26 for the ArNTAP treatment, and a significantly acidic pH of 4.76 ± 0.04 for the no-treatment groups. Our results suggest that FNTAP has exceptional anti-biofilm effects, and future directions of our research include the assessment of potential applications of FNTAP in clinical settings. Full article
