Micro-tensile bond strength of adhesive systems applied on occlusal primary enamel

The aim of this study was to evaluate the micro-tensile bond strength of adhesive systems (OptiBond

Solo™, Kerr; Prime & Bond NT®, Dentsply) on occlusal surface of primary molars. The adhesives were

tested under manufacturers’ specifications and after contamination of the bonding site with saliva. Hourglass

cylindrical-shaped samples were obtained and subjected to a tensile force. No significant difference

was observed among the groups. OptiBond Solo™ and Prime & Bond NT® showed similar values of bond

strengths when applied on occlusal enamel of primary molar under either saliva contamination or not.
