title: An in vitro microleakage study of a new multi-purpose dental adhesive system.
abstract: Despite the advances made in the field of adhesive dentistry, microleakage still remains an area of concern, as a secure seal to dentine and cementum still cannot be achieved with certainty. This project compared the effectiveness of a new adhesive, Scotchbond Multi-Purpose Dental Adhesive System (SBMP) with an established product, Gluma Bonding System (Gluma) in preventing microleakage and the influence of storage, thermal and load cycling on microleakage patterns. In uncycled specimens, Gluma Bonding System had significantly less leakage (P < 0.01) at both occlusal and cervical margins. Thermocycling of composite restorations utilizing SBMP resulted in a significant decrease (P < 0.05) at the occlusal margins but had no effects on cervical leakage. Mechanical loading had no influence on leakage patterns either cervically or occlusally. Three months' storage and combined treatment resulted in a significant decrease in leakage (P < 0.05) at the occlusal margins.
