If needed, external bleaching is usually recommended before infiltration, whilst in clinical practice, this sequence may not always be feasible. This in vitro study evaluated the effect of bleaching after resin infiltration regarding surface roughness and color using bovine incisors. Unlike for the untreated specimens (control, n = 25), artificial caries lesions were created within the test group (n = 25) using a demineralization solution at 37 \u00b0C for five days (pH = 4.95). The lesions were subsequently infiltrated using a resin infiltrant (Icon, DMG, Hamburg, Germany), followed by polishing. Afterwards, all specimens were bleached with a 10% carbamide peroxide gel (Opalescence, Ultradent, South Jordan, UT, USA) for 8 h\/day over a ten-day period. Between bleaching treatments, specimens were stored in an opaque container with moistened paper tissues at 37 \u00b0C. Surface roughness was measured using a profilometer, and color in the L*a*b* space was assessed spectrophotometrically before and after bleaching. Bleaching increased the L*-values of both infiltrated (mean \u00b1 SD; \u0394L* = 3.52 \u00b1 1.98) and untreated (control) specimens (\u0394L* = 3.53 \u00b1 2.30) without any significant difference between the groups (p = 0.983). Bleaching also induced a significant increase in the mean surface roughness of both infiltrated (p &lt; 0.001) and untreated (p = 0.0134) teeth. In terms of clinical relevance; it can be concluded that bleaching resin-infiltrated enamel is as effective as bleaching sound enamel.<\/jats:p>","DOI":"10.3390\/jfb15050125","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T03:20:29Z","timestamp":1715656829000},"page":"125","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Effect of Bleaching on Resin-Infiltration-Masked Artificial White Spots In Vitro"],"prefix":"10.3390","volume":"15","author":[{"given":"Alan Leon","family":"Sinanovic","sequence":"first","affiliation":[{"name":"Clinical Research, DMG Dental-Material Gesellschaft mbH, 22547 Hamburg, Germany"},{"name":"Department Biotechnology, University of Applied Sciences Hamburg, 21033 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4466-5971","authenticated-orcid":false,"given":"Philipp","family":"Messer-Hannemann","sequence":"additional","affiliation":[{"name":"Clinical Research, DMG Dental-Material Gesellschaft mbH, 22547 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariam","family":"Samadi","sequence":"additional","affiliation":[{"name":"Clinical Research, DMG Dental-Material Gesellschaft mbH, 22547 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Falk","family":"Schwendicke","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Periodontology, Ludwig-Maximilians University Munich, 80336 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susanne","family":"Effenberger","sequence":"additional","affiliation":[{"name":"Clinical Research, DMG Dental-Material Gesellschaft mbH, 22547 Hamburg, Germany"},{"name":"Department of Conservative Dentistry and Periodontology, Ludwig-Maximilians University Munich, 80336 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104168","DOI":"10.1016\/j.jdent.2022.104168","article-title":"Impact of masking hypomineralization opacities in anterior teeth on the esthetic perception of children and parents: A randomized controlled clinical trial","volume":"123","author":"Athayde","year":"2022","journal-title":"J.
