Teeth were cut into slices (5 \u00d7 5 \u00d7 2 mm) and divided according to surface treatment into four subgroups (<jats:italic>n<\/jats:italic> = 10): no treatment (control), air abrasion (Alumina\u2010blasting; AB), bur roughening, and dichloromethane (DCM) subgroups. According to manufacturer recommendations, the treated tooth slices were bonded to the acrylic disk of DBRs. The SBS test was performed using a universal testing machine. ANOVA was used for results analysis followed by Tukey's post hoc tests (\u03b1 = 0.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>DCM and AB increased the SBS of acrylic teeth to heat\u2010polymerized DBR compared with other groups (<jats:italic>p<\/jats:italic> &lt; 0.001).
