Comment savoir si mon enfant est bien protйgй avec du fluorure? Comment le fluorure aide-t-il а prйvenir la carie? Le fluorure exerce un effet favorable sur la santй buccodentaire en rendant les dents plus rйsistantes а la carie. Le fluorure peut йgalement aider а prйvenir les caries, voire supprimer celles qui sont apparues.

Normal 0 The enamel represents the usual translucent semivitriform glass-like type of structure. The surface is smooth, glossy and usually of pale creamy white color Questionable 1 The enamel discloses slight aberrations from the translucency of normal enamel, ranging from a few white flecks to occasional white spots.
Frequently included in this classification are teeth showing no more than about 1 — 2mm of white opacity at the tip of the summit of the cusps, of the bicuspids or second molars. Moderate 4 All enamel surfaces of the teeth are affected and surfaces subject to attrition show wear. Brown stain is frequently a disfiguring feature Severe 5 All enamel surfaces are affected and hypoplasia is so marked that the general form of the tooth may be affected.
The major diagnostic sign of this classification is discrete or confluent pitting. Brown stains are widespread and teeth often present a corroded-like appearance. Primary dentine fluorosis and enamel fluorosis can only happen during tooth formation, so fluoride exposure occurs in childhood. Enamel fluorosis has a white opaque appearance which is due to the surface of the enamel being hypomineralised. There are a few possible mechanisms that have been proposed.
It is generally believed that the hypomineralization of affected enamel is mainly due to in-situ toxic effects of the fluoride on the ameloblasts in the enamel formation, and not caused by the general effects of fluoride on the calcium metabolism, or by the poisoning effects that suppress the fluoride metabolism.
However, despite decades of research and studies, there have yet to be any studies that substantiates the believed mechanism whereby dental fluorosis is a result of alteration in the mineralisation that takes place when fluroide interacts with mineralising tissues. This hypomineralized enamel has altered optical properties and appears opaque and lusterless relative to normal enamel.
Dental fluorosis can be prevented at a population level through defluoridation. It is the downward adjustment of the level of fluoride in drinking water. Management[ edit ] Dental fluorosis may or may not be of cosmetic concern. In some cases, there may be varying degrees of negative psychosocial effects. The treatment options are:.
