Abstract
Aim: aim of this study was to evaluate the thickness of oxygen inhibition layer (oil), produced on two composite materials
Objective: To evaluate the thickness of oxygen inhibition layer (oil), produced on two different composite materials.
Material and method: The thickness of oil on 2 different composite materials group1 n=30 - fiber reinforced composite and group 2 n=30 - nanohybrid composite were evaluated. The materials were divided into 3 subgroups depending on the surface treatment given i.e - (control group- a,water spray group -b, ethanol group -c.The depth of the inhibition layer was measured using stereomicroscope around the periphery at a magnification of 40x .The results were recorded in micrometers between the outer boundary of the specimen and the polymerized–unpolymerized resin interface. Results: compared to composites of (Group 1b and Group 1c fiber reinforced composite), the (Group 2c and Group 2b nanohybrid composite) displayed a maximum thickness of OIL.
Conclusion: The oxygen inhibition layer, which serves as an intermediary layer, is kept on the composite's surface after being exposed to either ethanol or water spray.However, whether the oxygen inhibition layer was present or not, the short fiber-reinforced composite shown a propensity for cohesive fractures.
