Abstract

Microleakage is a persistent challenge in adhesive dentistry and has a direct effect on the longevity of composite restorations. This in vitro study performed in accordance with the criteria of the preferred guidelines, investigated and compared, microleakage status of restorative bonded with etch-and-rinse, self-etch and universal adhesive systems. Twelve extracted human premolars were restored using standardized class V cavities and then utilized for dye penetration farming after thermocycling. Data analysis demonstrated statistically significant differences in sealing ability with respect to each adhesive group. Universal adhesives demonstrated a lower amount of microleakage than self-etch and etch-and-rinse systems. Microleakage is an important factor in adhesive bonding ultimately dictates failure or success the selection of an appropriate adhesive may relate to the reduction of adhesion and therefore increases the chance of restorative success.

Keywords
