This in vitro study evaluated three additional conditioning methods and two adhesive systems at aged composite\u2013new composite repair interfaces. Ninety extracted posterior teeth were restored, thermocycled, and partially prepared with a diamond bur to create standardized repair surfaces. The surfaces then received additional diamond-bur roughening, 50-\u00b5m Al2O3 airborne-particle abrasion, or Er:YAG laser irradiation and were treated with Clearfil SE Bond or Clearfil Universal Bond Quick 2 (n = 15 per combination). After repair and additional thermocycling, maximum linear dye penetration was measured as the primary outcome; a derived ordinal grade was analyzed as a supportive, exploratory secondary outcome. A two-factor permutation analysis detected no significant effect of conditioning method (p = 0.142), adhesive system (p = 0.606), or their interaction (p = 0.341) on linear microleakage. In the ordinal proportional-odds analysis, the method effect was not statistically significant (p = 0.053); neither the adhesive effect (p = 0.763) nor the interaction (p = 0.754) was significant. Under the tested conditions, statistically significant differences in microleakage were not detected among the evaluated combinations.<\/jats:p>","DOI":"10.3390\/ma19194149","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T08:12:42Z","timestamp":1790669562000},"page":"4149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Additional Surface Conditioning Methods and Adhesive Systems on Microleakage at Composite Repair Interfaces: An in Vitro Study"],"prefix":"10.3390","volume":"19","author":[{"given":"Iryna","family":"Ushatkina","sequence":"first","affiliation":[{"name":"EMDOLA, Wroclaw Medical University, Krakowska 26, 50-425 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6109-6809","authenticated-orcid":false,"given":"Zuzanna","family":"Grzech-Le\u015bniak","sequence":"additional","affiliation":[{"name":"Department of Experimental Dentistry, Faculty of Medicine and Dentistry, Wroclaw Medical University, Krakowska 26, 50-425, Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"}]},{"given":"Marek","family":"Milcarz","sequence":"additional","affiliation":[{"name":"EMDOLA, Wroclaw Medical University, Krakowska 26, 50-425 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"given":"Katarzyna","family":"Sko\u015bkiewicz-Malinowska","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Faculty of Medicine and Dentistry, Wroclaw Medical University, 50-425 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"validation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3801-0218","authenticated-orcid":false,"given":"Jacek","family":"Matys","sequence":"additional","affiliation":[{"name":"Dental Surgery Department, Faculty of Medicine and Dentistry, Wroclaw Medical University, Krakowska 26, 50-425 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5700-4577","authenticated-orcid":false,"given":"Kinga","family":"Grzech-Le\u015bniak","sequence":"additional","affiliation":[{"name":"Department of Integrated Dentistry, Faculty of Medicine and Dentistry, Wroclaw Medical University, Krakowska 26, 50-425 Wroclaw, Poland"},{"name":"Department of Periodontics, School of Dentistry, Virginia Commonwealth University, Richmond, VA 23298-0566, USA"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1016\/j.dental.2005.05.005","article-title":"Hygroscopic and hydrolytic effects in dental polymer networks","volume":"22","author":"Ferracane","year":"2006","journal-title":"Dent.
