Fifty rectangular metallic specimens made of Co-Cr alloy and fifty disk-shaped specimens made of PMMA were prepared according to the manufacturers\u2019 instructions. Fifty maxillary right central incisors were also included in the study. The above-mentioned specimens were equally divided into five groups (n = 10). Four disinfectant solutions were tested (0.1 wt% NaOCl, 0.5 wt% H2O2, 78 wt% ethanol, and 1 wt% Povidone Iodine), and freshly distilled water was used as the control. To simulate clinical practice, each specimen was immersed in the disinfectant solution 15 times. All specimens were marked, and surface roughness, gloss, and color were measured before and after immersion. All roughness parameters (Sa, Sq, Sz, Sc, and Sv) and gloss values before and after immersion were statistically compared. \u0394E*ab values were statistically compared with perception and acceptability thresholds according to ISO\/TR 28642. No significant differences were identified for surface roughness parameters for all groups tested. All materials demonstrated a significant increase in gloss after aging regime, while only the metallic specimens illustrated \u0394E*ab values higher than the acceptability threshold after disinfection with H2O2. None of the surface properties deteriorated after exposure to tested disinfectants, and thus, all of them can be effectively implemented in everyday practice.<\/jats:p>","DOI":"10.3390\/jfb16120446","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T16:47:37Z","timestamp":1764780457000},"page":"446","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Disinfectant Solutions Against COVID-19 on Surface Roughness, Gloss, and Color of Removable Denture Materials"],"prefix":"10.3390","volume":"16","author":[{"given":"Aikaterini","family":"Mikeli","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, School of Dentistry, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nick","family":"Polychronakis","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, School of Dentistry, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xanthippi","family":"Barmpagadaki","sequence":"additional","affiliation":[{"name":"Aesthetic & Prosthesis Dental Lab, Private Practice, 18544 Pireas, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0828-3423","authenticated-orcid":false,"given":"Gregory","family":"Polyzois","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, School of Dentistry, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2197-9495","authenticated-orcid":false,"given":"Panagiotis","family":"Lagouvardos","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry, School of Dentistry, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9188-7839","authenticated-orcid":false,"given":"Spiros","family":"Zinelis","sequence":"additional","affiliation":[{"name":"Department of Biomaterials, School of Dentistry, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,29]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2025).
