Abstract

Background: The aim of the study was to evaluate the influence of ozonated water application on dentin shear bond strength.
Materials and Methods: Ten dentin samples per group were pretreated as follows: (I) untreated served as –ve control, (II) sterile distilled water for 10 seconds served as +ve control, (III) 5.25% sodium hypochlorite (Sultan-USA) for 10 seconds, (IV) 0.2% chlorhexidine (Corsodyle®, England) for 10 seconds, and (V) 4mg/L ozonated water (Ozonesolution-Enaly, USA) for 10 seconds. Samples were bonded with type II DBA (Unibond 2-Ventura, Spain) based on two clinical steps, etch, prime and bond combined and restored with a composite (Ventura-Similux, Spain) according to the manufacturer instruction. After storage in water at 37°C for 2 days and thermo-cycled for 500 cycles, shear bond strength was measured using Instron machine. Data were analyzed using ANOVA and Student t-test.
Results: There was high significant increase in bond strength for ozonated water treated samples compared to controls at P<0.01.
Conclusions: According to the circumstances of this study, ozonated water can be used successfully as cavity disinfectant after cavity preparation to increase the shear bond strength of dentin to composite.
