Forty were prepared to create cut enamel surfaces, and 40 were left uncut. Each group was randomly divided into four subgroups (n=10) according to the type of surface treatment: no treatment (control), 18% ethylenediaminetetraacetic acid (EDTA), All-Bond Universal adhesive in etch-and-rinse (E&R) mode, and All-Bond Universal adhesive in self-etch (SE) mode. Surefil One self-adhesive bulk-fill composite resin was bonded to enamel, and μSBS was measured after 24 hours. Data were analyzed by two-way ANOVA and Tukey’s HSD post-hoc test (alpha=0.05).</p> <p><strong>Results: </strong>Two-way ANOVA showed significant main effects of enamel preparation (P<0.001) and surface pretreatment (P<0.001), as well as their significant interaction effect (P=0.005) on μSBS. Cut enamel exhibited a higher mean μSBS (7.12±2.66MPa) than uncut enamel (5.88±2.70MPa; P=0.019). Universal adhesive application in E&R mode yielded the highest μSBS, followed by the SE mode; whereas, EDTA and no-treatment groups showed the lowest μSBS values.</p> <p><strong>Conclusion:</strong> Cut enamel samples exhibited a greater μSBS in comparison to uncut samples. The highest μSBS values were observed when both cut and uncut enamel surfaces received pretreatment with a universal adhesive applied in E&R mode.</p>2025-11-28T15:24:54+00:00Copyright (c) 2025 Frontiers in Dentistry
