Adjustments to the occlusion or margins are commonly needed before cementing the temporary prosthesis. Therefore, it is clinically necessary to repolish the rough surface to avoid biological and esthetic issues associated with rough surfaces. The purpose of this in vitro study was to assess and compare the impact of various polishing protocols on the surface roughness and color stability of three resin materials used for provisional crowns. A total of 150 specimens were fabricated from auto-polymerizing polymethyl methacrylate, bis-acryl composite, and Methyl methacrylate-LC resin using a stainless steel mold. Each material group was divided into five groups (n = 10) based on the applied surface treatment: positive control group (G1): no roughening or surface treatment, Negative control group (G2): acrylic bur-roughened surface without any polishing, the different surface treatment groups of silicon carbide and aluminum oxide stone polishing (G3), diamond-coated rubber twist (G4), and Surface Glaze (G5). An optical profilometer was used to assess the surface roughness of all samples. After undergoing 6000 cycles of thermocycling followed by immersion in a coffee solution for 15 days at 37 \u00b0C, color parameters were measured using a spectrophotometer both before and after a storage period to evaluate color differences. A two-way ANOVA test with \u03b1 = 0.05 significance level was carried out to determine the impacts of both the materials utilized and the polishing protocol. Among the three types of resin examined, the bisacryl group exhibited superior surface quality in positive control groups, while PMMA resin demonstrated higher polishability. The diamond-coated rubber twits resulted in lower Ra values of 0.36 (0.01) \u00b5m, 0.52 (0.11) \u00b5m, and 0.28 (0.05) \u00b5m for PMMA, BAMA, and MMLC resins, respectively. The application of photo-polymerized surface glaze led to a plaque accumulation threshold of 0.2 \u00b5m across all resin groups. The greatest mean color change occurred in the negative control group, indicating a propensity for more staining on rougher surfaces. The Bisacryl resin exhibited higher \u0394E values, whereas PMMA showed better color stability. The lowest \u0394E values were found when the surface glaze was applied to all of the provisional crown resins. Untreated Bisacryl resin exhibited the lowest Ra values, while PMMA resins demonstrated superior surface morphology after polishing. PMMA provisional crown resins showed increased resistance to staining. The use of surface glaze enhanced both smoothness and color stability on the surfaces.<\/jats:p>","DOI":"10.3390\/jfb15090256","type":"journal-article","created":{"date-parts":[[2024,9,3]],"date-time":"2024-09-03T12:22:33Z","timestamp":1725366153000},"page":"256","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Comparison of Various Surface Treatment Procedures on the Roughness and Susceptibility to Staining of Provisional Prosthodontic Materials"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7871-1513","authenticated-orcid":false,"given":"Satheesh B.","family":"Haralur","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, College of Dentistry, King Khalid University, Abha 62529, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1969-4694","authenticated-orcid":false,"given":"Abdullah Turki","family":"Albarqi","sequence":"additional","affiliation":[{"name":"College of Dentistry, King Khalid University, Abha 62529, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulellah Gharmallah","family":"Alamodi","sequence":"additional","affiliation":[{"name":"College of Dentistry, King Khalid University, Abha 62529, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulmajeed Ali","family":"Alamri","sequence":"additional","affiliation":[{"name":"College of Dentistry, King Khalid University, Abha 62529, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saad Awdah","family":"Aldail","sequence":"additional","affiliation":[{"name":"College of Dentistry, King Khalid University, Abha 62529, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed A.","family":"Al-Qarni","sequence":"additional","affiliation":[{"name":"Department of Restorative Dentistry, College of Dentistry, King Khalid University, Abha 61471, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9669-2408","authenticated-orcid":false,"given":"Saeed M.","family":"AlQahtani","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, College of Dentistry, King Khalid University, Abha 62529, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nasser M.","family":"Alqahtani","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, College of Dentistry, King Khalid University, Abha 62529, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"118","DOI":"10.1016\/j.prosdent.2005.05.004","article-title":"Effects of different drinks on stainability of resin composite provisional restorative materials","volume":"94","author":"Guler","year":"2005","journal-title":"J.
