Clinical indications for the use of the low-concentration fluoride dentifrice

Abstract

The anti-caries efficiency of F dentifrices containing about 1100 ppmF, also called conventional, it is well documented. However its use by young children is also pointed out as risk factor to dental fluorosis. Thus, low-F dentifrice has been recommended for young children as an alternative to reduce dental fluorosis risk. In this sense, two principal issues must be elucidated: a) Is there evidence of the anticaries effect from the use low-F dentifrice? b) The use of low-F dentifrices by young children contributes to reduce the prevalence of fluorosis in permanent dentition? Evidence-based literature show that only dentifrice with 1000 ppmF (or more) can be safely indicated for preventing dental caries, and it is uncertain that the use of low-F dentifrice by young children can reduce dental fluorosis risk. Early childhood caries is universal health problem that prevalence increased with age, so is important to adopt preventive measures for this age group. In conclusion, we can be recommended as good oral health practices for children: the brushing should begin as soon teeth erupted, it should be realized twice daily with fluoridated toothpaste under the supervision, using a small amount of conventional dentifrice.
