The study duration was two months, 20th November 2025 - 20th January 2026. Primary CAD was removed. All the specimens were divided into four groups based on the application of ERA modification. Group-1 (Conventional ERA), Group-2 (Ery-modified ERA), Group-3 (Ery-doped ZrO2NPs modified ERA), and Group-4 (Ery-doped SepNPs modified ERA). Composite build-up was performed on all the specimens after adhesive application and exposed to \u00b5TBS testing and fracture analysis. All adhesives (modified and unmodified) were further tested for antimicrobial efficiency against Lactobacillus. The statistical analysis was conducted using a one-way analysis of variance (ANOVA) and a Tukey post hoc test.\nResults: Group-4 (Ery-doped SepNPs-ERA) treated samples displayed the minimum survival of microorganisms (0.30 \u00b1 0.04 CFU\/mL) and the highest bond integrity (15.02\u00b10.61MPa). However, Group-1 (Unmodified ERA) exhibited the maximum count of bacterial survival (0.65 \u00b1 0.11 CFU\/mL)and the lowest \u03bcTBS (10.95\u00b10.55MPa).\nConclusion: Ery-doped ZrO2NPs and Ery-doped SepNPs modified adhesive presented satisfactory antimicrobial activity against Lactobacillus and \u03bcTBS as compared to the unmodified adhesive when bonded to primary dentin.<\/jats:p>","DOI":"10.12669\/pjms.42.8.16412","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T05:42:58Z","timestamp":1785217378000},"page":"2059-2065","source":"Crossref","is-referenced-by-count":0,"title":["Sepiolite and Zirconia Nanoparticles Doped with Erythrosine: Adhesive Bond Strength and Antimicrobial Performance in Primary Carious Dentin"],"prefix":"10.12669","volume":"42","author":[{"given":"Abeer","family":"Ali Alshami","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiba","family":"F Kattan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4935","published-online":{"date-parts":[[2026,7,28]]},"container-title":["Pakistan Journal of Medical Sciences"],"original-title":[],"link":[{"URL":"https:\/\/pjms.org.pk\/index.php\/pjms\/article\/download\/16412\/11583","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/pjms.org.pk\/index.php\/pjms\/article\/download\/16412\/11583","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T05:42:59Z","timestamp":1785217379000},"score":1,"resource":{"primary":{"URL":"https:\/\/pjms.org.pk\/index.php\/pjms\/article\/view\/16412"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,28]]},"references-count":0,"journal-issue":{"issue":"8","published-online":{"date-parts":[[2026,7,27]]}},"URL":"https:\/\/doi.org\/10.12669\/pjms.42.8.16412","relation":{},"ISSN":["1681-715X","1682-024X"],"issn-type":[{"value":"1681-715X","type":"electronic"},{"value":"1682-024X","type":"print"}],"subject":[],"published":{"date-parts":[[2026,7,28]]}}}
