Use of fluoride and sealants
The incorporation of fluoride into the hydroxyapatite crystal results in the formation of fluorapatite; this structural unit of the enamel has a lower solubility in acid media. The fluoride has a bacteriostatic effect and modifies the surface tension of the enamel, delaying the adhesion of microorganisms. It may be incorporated systemically, through milk, salt or water, or topically, using toothpastes, topical applications, mouthrinses, or by means of the dental restoration materials themselves. Another caries prevention method are the sealants, which may be ceramic or glass ionomer-free resins, that have the property of releasing fluoride and are indicated in teeth with deep grooves and in patients with a high risk of suffering caries (8)(45)(57).
