Adhesion can be influenced by adhesives spreading. Both slow and fast spreading can be deleterious as they can respectively lead adhesive to partially cover the demineralized substrate or to accumulate on line angles of cavity preparations. Since brands of dentin bonding systems present distinct compositions and thus different behaviors its important to know how fast they spread over dental substrates. The purpose is to determine the influence of surface inclinations on the spreading velocity of simplified adhesive systems.

Materials and methods

Spreading velocities of adhesive systems (Adper Single Bond, Adper Single Bond Plus, Adper Prompt, Prime and Bond 2.1, Prime and Bond NT, One-Up Bond F) were measured on glass slide surfaces inclined at 45° and 90°. The spreading of each drop was observed at a 30 seconds interval. Data was recorded and the values obtained at 30 seconds were analyzed by two-way ANOVA and Student-Newman-Keuls (SNK) tests (α = 0.05).


The type of adhesive system and the angle of inclination influenced spreading velocity (p < 0.05). Adper Single Bond Plus and One-Up Bond F exhibited the lowest spreading velocities of all materials tested (p < 0.01). Adhesives spreading were similar on surfaces inclined 45° and 90°, except for Adper Single Bond Plus which spread faster and Prime and Bond NT that spread slower on 90° angled surfaces (p < 0.01).


The materials tested showed complex spreading patterns since the spreading velocities changed only when some specific material/inclination combinations where tested.
