Abstract
The aim of the study is the evaluation of the fluoride ions concentration retained in the whole saliva after the use of a topical fluoridated agent – „Fluocal Gel”. Material and methods The study group consisted of 20 children aged 13 years old. Their parents were informed about the importance of the professional topical fluoridation. The fluoride agent was applied in individual trays, for 4 minutes, with salivary aspiration. The paraffin-stimulated saliva was collected first before the fluoridation and then after 5minutes and 1, 2, 12, 24 and 48 hours. The fluoride ions concentration in the salivary samples was assessed with a fluoride-sensitive electrode. The results show that fluoride concentration in saliva has important levels in the first 24 hours after the use of the fluoride agent, at the same time the salivary pH being kept at a neutral level along this period. Conclusion. The increase of the fluoride concentration in saliva through the use of fluoridated concentrated agents is a very efficient method to prevent dental caries by several mechanisms, the most important being the inhibition of the enamel demineralization and the stimulation of the remineralization of the incipient caries.
