Buccal enamel surfaces on 80 extracted human primary incisors were used and randomly assigned into four groups (n=20); group 1: Vertise (TM) Flow; group 2: Vertise Flow with acid etching; group 3: Vertise Flow with a self-etching bonding agent; group 4: Premise FlowableTM with a total-etch bonding agent as the control group. After 5000 rounds of thermocycling, the bond strength test was performed using a universal testing machine at a crosshead speed of 0.5 mm/min. The fracture analyzes of samples were evaluated using a light stereomicroscope. The results obtained were analyzed via analysis of variance (ANOVA) and Tukey's tests. Statistically significant differences were observed among all groups (P<0.001). Group 1 generated a lower mean shear bond strength (2.63 +/- 1.08 MPa) than those of the other groups [group 2 (7.52 +/- 2.14 MPa), group 3 (5.12 +/- 2.93 MPa), and group 4 (14.18 +/- 2.93 MPa)]. Adhesive failure was the most common failure mode in Vertise Flow groups. Vertise Flow used with a self-etching agent or acid etching exhibited in lower shear bond strength than the control group.eninfo:eu-repo/semantics/closedAccessDental materialsPrimary teethSelf-adhesive flowable compositeShear bond strengthVertise (TM) flowArticle513361367WOS:000700970100005Q4
