PURPOSE The aim of this study was to evaluate the effect of paracetic acid (PAA) and ozone disinfection on the tensile bond strength (TBS) of silicone-based resilient liners to acrylic resins. MATERIALS AND METHODS One hundred and twenty dumbbell shaped heat-polymerized acrylic resins were prepared. From the mid segment of the specimens, 3 mm of acrylic were grinded off and separated parts we...

In this study the variation of dissolved ozone in deionized water was investigated using real-time measurement technique. The gas generated by a homemade coaxial dielectric barrier discharge and injected into bottom column via bubbler. values concentration were measured UV absorption spectra obtained two quartz windows mounted inside column. results showed fast increasing at first 3 min then, r...
