Fluoride in Caries Prevention: Is the Effect Pre- or Post-eruptive?

摘要: A longitudinal study of children from ages 7 to 18 showed that, if enamel lesions were included, the overall number was same in fluoridated and non-fluoridated areas. However, a significant reducing effect pre-eruptive fluoride could be seen dentinal area, provided that also consumed post-eruptively for considerable period time. precise estimation both pre- post-eruptive effects obtained when teeth classified according their eruption time as related onset water fluoridation. About 66% greatest reduction pit fissure caries came fluoride, while smooth surfaces, this reduced 25%. In approximal due half fluoride. Post-eruptive became more important with decreasing severity attack. Thus, assuming continuing decline dental caries, majority such populations will benefit most use topical fluorides. high-risk groups, supplementation can still major importance.
