Protective effect of NaF/triclosan/copolymer and MFP dentifrice on enamel erosion.
OBJECTIVE
To evaluate in situ the protective effect of sodium fluoride (NaF)/triclosan/copolymer dentifrice compared with monofluorphosphate (MFP) dentifrice on eroded enamel.


METHODS
The specimens were subjected to erosion with cola soft drink for 60 seconds, four times a day, for 5 days, followed by treatment with the slurry of nonfluoridated, NaF (1450 ppm F/triclosan/copolymer) or MFP (1450 ppm F) dentifrices. Their effects were assessed by surface hardness loss.


RESULTS
The dentifrice containing NaF/triclosan/copolymer was statistically more effective on reduction of enamel acid erosion than the non-fluoride and the MFP dentifrice (P < 0.05).
