Fluorides Essay -- Health, Dental Access

Fluoridation: The Big Debate The issue of fluoridation has always raised big questions regarding its effectiveness, safety and usage. Some of the main pros and cons of fluoridation shall therefore be explored. Pros: Large Reach: All members of the community would have access to regular fluorides doses, regardless of income, education or dental access. It many be particularly beneficial to children, as studies have shown that they do not brush as regularly as they should. Therefore, the omission of this administration fluoride can be compensated through water fluoridation, which all children should and would drink. Advantageous for the Elderly: As you get older, one’s saliva flow would generally decrease. This would mean that the elderly have less salivary fluorides that could access, remineralise and strengthen tooth surfaces. Moreover, the elderly have decreased manual dexterity to brush effectively and reach all surfaces. Therefore, all of these issues increase the risk of root surface decay for the elderly, but fluorides would help prevent this from occurring. Evidence: Many studies have been carried out to show that fluoridation of water does have a positive impact on oral hygiene and helping to prevent dental decay. Support: The fluoridation of water is supported by large health bodies such as: The British Dental Association; The World Health Organisation; The British Medical Association; and the British Fluoridation Society. Cost Effective: The use of fluorides reduces the risk of dental caries, and so potentially saves money for a patient who otherwise would have had to have payed for fillings. Reduces the Risk of Dental Caries: A recent study has concluded that adding fluoride... ... consuming hot or cold substances.[45] 5 things required for remineralisation of tooth enamel[36] The correct minerals (containing Ca2+, PO43- and Fl- ions) must be present in one’s saliva. Carbonic acid must then be produced (naturally produced from carbon dioxide and water) and close to the minerals, so it reacts with and dissociate them into their constituent ions. This process must take place near the tooth area affected. The affected demineralised area of hydroxyapatite must be clean and accessible. Complementary shaped ions formed from the minerals can then attract to oppositely charged ions within the hydroxyapatite lattice. Carbonic acid must then reform carbon dioxide and water, which precipitates the complementary ions that were dissolved in it into the area of demineralised enamel. In this way, remineralisation of the tooth enamel has occurred.
