Gutta-percha discs (n = 3 per group) were dip-coated with F18 bioactive glass at 2.5%, 5%, and 10% by weight and analyzed by SEM and EDS before and after 28 days of immersion in PBS. Uncoated gutta-percha served as the control for analyses. For the tensile bond strength test, twelve specimens per group (n = 12) were prepared using unmodified gutta-percha, 5% F18 dip-coated gutta-percha, or 2% F18-incorporated gutta-percha, each tested with BCS and AHP. Unmodified gutta-percha with each sealer served as the control. Bond strength was measured using a universal testing machine and analyzed by two-way ANOVA and Tukey's test (\u03b1 = 0.05). After PBS immersion, the 5% and 10% dip-coated groups exhibited more pronounced F18 deposition and the formation of continuous bioactive surface layers, whereas the control group showed no such features. Regarding bond strength, the 5% F18 dip-coated gutta-percha showed higher values with BCS compared to the control (p &lt; 0.05), and the 2% F18-incorporated gutta-percha also increased bond strength to BCS versus the control (p &lt; 0.05). For AHP, 5% dip-coating reduced bond strength compared with the control (p &lt; 0.05), whereas 2% incorporation did not differ (p &gt; 0.05). F18 bioactive glass promoted surface mineralization of gutta-percha and improved its bond strength to Bio-C Sealer, whether applied by dip-coating or incorporation.<\/jats:p>","DOI":"10.1590\/0103-644020256767","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T15:05:47Z","timestamp":1769785547000},"source":"Crossref","is-referenced-by-count":1,"title":["Effect of F18 Bioactive Glass-Treated Gutta-Percha on Interaction with Endodontic Sealers"],"prefix":"10.1590","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-1987-474X","authenticated-orcid":false,"given":"David Hern\u00e1ndez","family":"Maldonado","sequence":"first","affiliation":[{"name":"S\u00e3o Paulo State University,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0372-1375","authenticated-orcid":false,"given":"Jos\u00e9 Leandro de Abreu","family":"Jampani","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo State University,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1916-1675","authenticated-orcid":false,"given":"Airton Oliveira","family":"Santos-J\u00fanior","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo State University,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0291-6034","authenticated-orcid":false,"given":"Marina Trevelin","family":"Souza","sequence":"additional","affiliation":[{"name":"Federal University of S\u00e3o Carlos,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4931-4505","authenticated-orcid":false,"given":"Edgar Dutra","family":"Zanotto","sequence":"additional","affiliation":[{"name":"Federal University of S\u00e3o Carlos,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0446-2037","authenticated-orcid":false,"given":"Juliane Maria","family":"Guerreiro-Tanomaru","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo State University,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2574-4706","authenticated-orcid":false,"given":"M\u00e1rio","family":"Tanomaru-Filho","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo State University,  Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2025]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"1177","DOI":"10.1111\/iej.12269","article-title":"Micro-CT evaluation of root filling quality in oval-shaped canals","volume":"47","author":"Kele\u015f A","year":"2014","journal-title":"Int Endod J"},{"key":"ref2","article-title":"Effect of obturation technique using a new bioceramic sealer on the presence of voids in flattened root canals","volume":"35","author":"Santos-Junior AO","year":"2021","journal-title":"Braz Oral Res"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"976","DOI":"10.1002\/jemt.23658","article-title":"Micro-CT evaluation of filling of flattened root canals using a new premixed ready-to-use calcium silicate sealer by single-cone technique","volume":"84","author":"Tavares KIMC","year":"2021","journal-title":"Microsc Res Tech"},{"key":"ref4","doi-asserted-by":"crossref","DOI":"10.1155\/2018\/1731857","article-title":"Push-Out Bond Strength of Experimental Apatite Calcium Phosphate-Based Coated Gutta-Percha","author":"Al-Haddad AY","year":"2018","journal-title":"Int J Biomater"},{"key":"ref5","article-title":"Functionalization of gutta-percha surfaces with argon and oxygen plasma treatments to enhance adhesiveness","volume":"13","author":"Ferreira I","year":"2023","journal-title":"Sci Rep"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"1679","DOI":"10.3390\/polym15071679","article-title":"Apical Sealing and Bioactivity of an Experimental Gutta-Percha Containing Niobium Phosphate Bioglass","volume":"15","author":"Sampaio RF","year":"2023","journal-title":"Polymers"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"669","DOI":"10.4103\/JCDE.JCDE_295_25","article-title":"Could the sealer thickness affect the filling ability of bioceramic endodontic materials?
