Bioeng.

In present study, two groups of experimental CRs loaded with different contents of fluoride-doped nano-zirconia fillers (25\u00a0wt% and 50\u00a0wt%) were fabricated. The surface topography, mechanical performance, fluoride release, antibacterial effect, aging property and cytotoxicity of the experimental CRs were evaluated subsequently. A uniform distribution of the F-zirconia fillers over the whole surface of resin matrix could be observed. The experimental CRs showed continuous fluoride release within 28 days, which was positively correlated with the content of F-zirconia fillers. Moreover, the amount of fluoride release increased in the acidic buffer. Addition of F-zirconia fillers could improve the color stability, wear resistance and microhardness of the experimental CRs, without reducing the flexure strength. Furtherly, the fluoride ions released continuously from the experimental CRs resulted in effective contact and antibacterial properties, while they showed no cytotoxicity. As a consequence, considerations can be made to employ this new kind of composite resin loaded with fluoride-doped nano-zirconia fillers to meet clinical requirements when the antimicrobial benefits are desired.<\/jats:p>","DOI":"10.3389\/fbioe.2024.1397459","type":"journal-article","created":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T04:45:16Z","timestamp":1716439516000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Study on the mechanical and aging properties of an antibacterial composite resin loaded with fluoride-doped nano-zirconia fillers"],"prefix":"10.3389","volume":"12","author":[{"given":"Liyuan","family":"Zheng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuming","family":"Bai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhisheng","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qianju","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,5,23]]},"reference":[{"key":"B1","article-title":"Therapeutic roles of fluoride released from restorative dental materials","author":"Ahmed","year":"2015","journal-title":"Fluoride"},{"key":"B2","doi-asserted-by":"publisher","first-page":"6831","DOI":"10.3390\/ma16216831","article-title":"Comparison of shear bond strength of three types of adhesive materials used in the restoration of permanent molars after treatment with silver diamine fluoride: an in vitro study","volume":"16","author":"Aldowsari","year":"2023","journal-title":"Mater.
