Average surface roughness (Ra) and the depth of surface removal of specimens were measured over time, and the clinical number of microbial adhesions on the mucosal surface of dentures was clinically assessed. The results obtained showed no changes in Ra after 20 s of polishing, Ra of &lt;0.2 \u00b5m, and a depth of surface removal &lt; 20 \u00b5m. This method of finishing did not affect the fit of the mucosal surface of the dentures. Furthermore, the adhesion of microorganisms to the mucosal surface of dentures was significantly suppressed. Shot blast polishing with viscoelastic media is useful for finishing the mucosal surface of resin denture bases.<\/jats:p>","DOI":"10.3390\/ma15062275","type":"journal-article","created":{"date-parts":[[2022,3,20]],"date-time":"2022-03-20T21:30:14Z","timestamp":1647811814000},"page":"2275","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Impact of Surface Changes and Microbial Adhesion on Mucosal Surface Finishing of Resin Denture Bases by Shot Blast Polishing Using Viscoelastic Media"],"prefix":"10.3390","volume":"15","author":[{"given":"Yusuke","family":"Yamashita","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Prosthodontics, Field of Oral and Maxillofacial Rehabilitation, Kagoshima University Graduate School of Medical and Dental Sciences, Kagoshima 890-8544, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6703-5978","authenticated-orcid":false,"given":"Yasuhiro","family":"Nishi","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Prosthodontics, Field of Oral and Maxillofacial Rehabilitation, Kagoshima University Graduate School of Medical and Dental Sciences, Kagoshima 890-8544, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6997-9710","authenticated-orcid":false,"given":"Mamoru","family":"Murakami","sequence":"additional","affiliation":[{"name":"Department of Removable Prosthodontics and Implant Dentistry, Advanced Dentistry Center, Kagoshima University Hospital, Kagoshima 890-8544, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7620-9212","authenticated-orcid":false,"given":"Kae","family":"Harada","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Prosthodontics, Field of Oral and Maxillofacial Rehabilitation, Kagoshima University Graduate School of Medical and Dental Sciences, Kagoshima 890-8544, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Nishimura","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Prosthodontics, Field of Oral and Maxillofacial Rehabilitation, Kagoshima University Graduate School of Medical and Dental Sciences, Kagoshima 890-8544, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1271","DOI":"10.1016\/j.prosdent.2014.03.023","article-title":"Investigation of the effect of different polishing techniques on the surface roughness of denture base and repair materials","volume":"112","author":"Gungor","year":"2014","journal-title":"J.
