This research intends to conduct a comparative analysis between a conventional and mechanized polishing protocol concerning surface roughness and its impact on surface topography. Thirty samples were included in this in vitro study: six samples for each type of acrylic resin. All specimens underwent a polishing protocol by a conventional method and a mechanized approach with a controlled polishing tool (CPT). Profilometric measures were extracted: arithmetic mean height (Pa), skewness (Psk) and kurtosis (Pku). The Pa values acquired through both the mechanized and conventional polishing techniques are significantly lower compared to the control group. The mechanized polishing notably yielded higher roughness compared to the control group. Relatively consistent skewness and lower-to-moderate values of kurtosis were found across resin types. Differences in the dispersion and pattern for Pa were not detected between the polishing protocols. The CPT protocol reliably maintains consistent skewness and kurtosis values. The conventional protocol remains significant due to the variations observed in the Pa values obtained.<\/jats:p>","DOI":"10.3390\/app15020605","type":"journal-article","created":{"date-parts":[[2025,1,9]],"date-time":"2025-01-09T11:29:37Z","timestamp":1736422177000},"page":"605","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative Analysis of Mechanized Versus Conventional Polishing Protocols for Denture Base Acrylic Resins"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5906-0014","authenticated-orcid":false,"given":"Margarida Martins","family":"Quezada","sequence":"first","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Dental Medicine, Universidade Cat\u00f3lica Portuguesa, 3504-505 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4249-2352","authenticated-orcid":false,"given":"Carlos","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Faculty of Engineering (FEUP), Universidade do Porto, 4099-002 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3936-6539","authenticated-orcid":false,"given":"Javier","family":"Montero","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Department of Surgery, University of Salamanca, 37008 Salamanca, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0119-9790","authenticated-orcid":false,"given":"Andr\u00e9","family":"Correia","sequence":"additional","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Dental Medicine, Universidade Cat\u00f3lica Portuguesa, 3504-505 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1500-8465","authenticated-orcid":false,"given":"Patr\u00edcia","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Dental Medicine, Universidade Cat\u00f3lica Portuguesa, 3504-505 Viseu, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"796","DOI":"10.1016\/j.prosdent.2020.06.007","article-title":"Effect of a continuous mechanical polishing protocol on the color stainability, microhardness, mass, and surface roughness of denture base acrylic resin","volume":"126","author":"Melo","year":"2021","journal-title":"J.
