Abstract

Statements of Problem: The goal of adhesive dentistry is creation of perfect seal along resin-dentin interface. However, small ions and molecules can permeate the hybrid layer even in the absence of detectable interfacial gap formation. This phenomen is called "NANOLEAKAGE".Purpose: The aim of this in vitro study was to compare the NANOLEAKAGE of 3 selfetch adhesive systems in dry and wet conditions on human dentin. Materials and Method: Seventy-seven intact human premolars were selected and flat occlusal surfaces were prepared. Teeth were divided into 7 groups of 11 teeth and each group was treated according to the following protocol: group 1: clearfil SE Bond in dry condition, group 2: clearfil SE Bond in wet condition, group 3: I Bond SE Bond in dry condition, group 4: I Bond SE Bond in wet condition, group 5: prompt L-pop in dry condition, group 6: propmpt L-pop in wet condition and group 7: scoth Bond Multipurpose (control). In dry condition, the dentin surfaces were air-dried for 10 seconds and in wet condition, dentin surfaces were blot dried. Adhesives and composite resins were bonded to dentin surfaces. After 24 hours, all teeth were stored in 50% AgNo3 solution in darkness for 24 hours. Then the teeth were rinsed and stored in photodeveloper solution under flouresceut for 8 hours. The prepared teeth were embedded in epoxy resin and sectioned as 1 mm diameter. All slabs were polished, gold coated and analyzed by SEM.Results: The mean NANOLEAKAGE of the 3 SELF ETCH ADHESIVEs in dry condition was significantly higher than the wet condition. The mean NANOLEAKAGE of 3 SELF ETCH ADHESIVEs had no significant difference in wet condition. In dry condition, PLP was better than CSEB and IB.Conclusion: Based on this study, it is recommended to dry the dentin, before application of SELF ETCH ADHESIVEs. The water content of these BONDING systems is enough for the release of H+ which is necessary for the activation of acidic monomer.
