Abstract
Background: Because of their aesthetic appeal, whitening toothpastes are now a common habit, especially among young adults. The effects of brushing with those novel dentifrices on the wear characteristics of resin composites are unknown. Materials and Methods Sixty prepared samples of composite resin fabricate in plastic matrix and stored in distilled water for 24h. For surface roughness measurements, using Stylus profilometer and this considered initial roughness value. The specimens were randomly divided into three groups. Group A use distal water (Control Group), group B Oral B 3D White Perfection toothpaste, group C Colgate Luminous White Brilliant. After this, the electric toothbrush was used to brush the specimens in the three groups investigated for 2 minutes twice a day for 30 consecutive days, Surface roughness measurements using also stylus profilometer and micro hardness test this considered final values. Result: In Experiment there was greater diffrenss in GB and G C in relation to GA, with no differences among them. Conclusion: whitening dentifrices containing Blue covarine (optical agent) have an influential effect on surface characteristics (Superficial roughness and micro hardness) of nanoparticular composite resin.
