Advantages And Disadvantages Of Water Fluoridation

Better Essays

WATER FLUORIDATION: - A high degree of reduction in caries/ tooth decay occur when fluoride content is approximately IPPM (i.e. one part of fluoride to one million part of water), the prevalence of oral fluorosis increase greatly when the concentration of fluoride is more than 1pm. Therefore, the optimal concentration of community fluoridation is 1pm. The very first community water fluoridation was in Grand Rapids in USA in 1945 and these produced a reduction in caries between 40-50% in deciduous teeth while in permanent dentition is 50-60%. Apart from caries reduction, there is also a slower rate of progression of caries lesion less involvement of oral pulp. Many more people have caries free teeth or dentition. It was noticed that these four differences occur and its lifelong protection for the water fluoridation is interrupted the caries protective effect is diminished. Drinking habits are affected by temperature and failure to make adjustment for this many result in increasing incidence in fluorosis in one climate. To achieve maximum protection for both primary and secondary teeth, the consumption of fluoridated water is essential as it acts directly as topical agent as well as systematically during teeth formation. Proximal and surfaces are more protected than pits fissures. ADVANTAGE OF WATER FLUORIDATION (WHO 1984):- The major advantage of water fluoridation is that apart from school (students) the entire community benefits adequately irrespective of age,
