Remineralization potential of 5,000 ppm fluoride dentifrices evaluated in a pH cycling model
Prescription 1.1% sodium fluoride (NaF) dentifrices designed to either have fast dispersion for improved enamel fluoride uptake (that is, PreviDent® Booster 5000) or contain an innovative tricalcium phosphate system for enhanced remineralization (that is, Clinpro® 5000) were evaluated for anticaries potential in an in vitro pH cycling model. Polished bovine enamel specimens were initially...

Effects of different concentrations of bleaching agent on the micro hardness and shear bond strength of restorative materials – An in vitro study
With the growing awareness of esthetics, the use of bleaching agents are on the increase. Bleaching agents intended to be used at home affects the existing restorations. The aim of the present study was to evaluate the effect of bleaching with carbamide peroxide agents at concentrations 10 and 22% on the microhardness and shear bond strength of composites and compomers. For microhardness and shear bond strength...
