Abstract
Background & Aim: During cavity preparation, smear layer is created that this layer should be removed with irrigators. Leakage may be decrease after irrigation. The aim of this study was to evaluate the leakage after irrigation by chlorhexidine 2%, sodium hypochlorite 2.5% and water in glass ionomer class V restorations.
Materials and Method: In this experimental-in vitro study, the class V restoration preparation was prepared in the standard cervical portion of buccal accept in 51 human premolar teeth. The samples were divided to 3 groups due to type of irrigants. Group 1: sodium hypochlorite 2.5% was applied in cavity for 30 seconds. Group2: chlorhexidine 2% was applied in cavity for 30 seconds. Then, all cavities were washed for 10 seconds in order to remove agents and their extra waters. Group3: only washed with water. The cavities were filled by Glass ionomer reinforced composite resins. After 1000 thermal cycles of 5-55 °c, the microleakage of samples, was evaluated with dye penetration and data was analyzed statistically with chi-square.
Results: The microleakage of enamel were 94.1% in water irrigant, 41.2% in chlorhexidine 2%, 17.6% in sodium hypochlorite 2.5% (p<0.001) and for dentin, in water, chlorhexidine 2% and sodium hypochlorite 2.5% were 88.2%, 70.6% and 17.6% respectively. (p<0.001)
