title: Benefits and risks of fluoride supplementation: caries prevention versus dental fluorosis.
abstract: To assess the risks (dental fluorosis) and the benefits (caries prevention) of fluoride (F) tablets and F toothpaste, we surveyed 2003 schoolchildren aged 5-20 years old (mean = 10.82, SD = 3.40). Children were scored for dental caries by means of the decayed, missing, filled teeth index (DMFT index). Frequent use of F toothpaste (toothbrushing frequency) is poorly linked to caries (Spearman r = 0.05, P = 0.02) and dental fluorosis (r = 0.05, P = 0.03). Children who use F tablets regularly and appropriately exhibit mild fluorosis more often than non- or occasional users (odds ratio = 9.58), and have a mean DMFT index 50% lower than other children. We conclude that using F tablets is an effective means of preventing caries. When used appropriately in non fluoridated areas, using F tablets results in minor damage.
