Resumo(s)
O flúor ganhou uma grande importância na Medicina Dentária, desde que foi introduzido nos materiais dentários há 70 anos atrás. A sua atuação no equilíbrio desmineralização-remineralização do esmalte e influência no metabolismo das bactérias cariogénicas fez com que fosse uma mais valia incorporar este composto nos materiais restauradores. Em Odontopediatria torna-se essencial recorrer a um material que tenha uma longevidade semelhante ao dente, de fácil manuseamento, com boa adesão à superfície dentária e com um efeito terapêutico. A utilização de materiais libertadores de flúor contribui para manter níveis intraorais de flúor suficientes para um efeito cariostático. Objetivo: Com recurso à literatura, pretende-se fazer uma revisão narrativa sobre a utilização dos materiais restauradores libertadores de flúor em Odontopediatria. Metodologia: Efetuou-se uma pesquisa com término a 25 de Maio de 2017 nas bases de dados primárias MEDLINE (através da Pubmed), Science Direct, Cochrane Library e NHS Evidence, utilizando combinações com “AND” das palavras-chave: “deciduous tooth”, “fluoride”, “restorative materials”, “glass ionomer”. As guidelines de prática clínica da American Academy of Pediatric Dentistry fizeram parte integral da pesquisa. Também se recorreu a fontes de pesquisa secundárias nomeadamente artigos primários referenciados em bibliografia resultante da pesquisa inicialmente efetuada. Discussão e Conclusão: Os materiais de restauração fluoretados possuem claras diferenças na sua constituição, capacidade de libertação e recarga de flúor e influência na atividade cariogénica. Estes materiais podem atuar como reservatórios de flúor, aumentando os seus níveis intraorais. Contudo, os estudos analisados são pouco uniformes e alguns apresentam um curto follow-up.
Introduction: Fluor was incorporated in dental material 70 years ago and since then, it has gained a huge importance in dentistry. The balance demineralization-remineralization in enamel and the influence in bacterial metabolism are some of the mechanisms of action of fluoride, which was the reason of the incorporation in some restorative materials. In Pediatric Dentistry, a material that has a longevity similar to the tooth, improved handling, chemical bonding to enamel and dentin and can work as an interim therapeutic restoration is essential. The use of fluoride-containing restorative materials may support intraoral fluoride levels and lead to a cariostatic effect. Aim: The purpose of this dissertation is to review the fluoride release restorative materials in Pediatric Dentistry. Methodology: A review of the scientific literature was made until 25/05/2017 in electronic databases such as MEDLINE (Pubmed), Science Direct, Cochrane Library e NHS Evidence. The keywords used were “deciduous tooth”, “fluoride”, “restorative materials”, “glass ionomer”. Clinical Practice Guidelines from American Academy of Pediatric Dentistry were also included in the search. Secondary sources were examined by the search of articles referenced in the papers from electronic databases. Discussion and Conclusion: Fluoride-containing restorative materials have clear differences in their composition, in the fluoride release and uptake characteristics and in cariogenic activity. These materials may act as a fluoride reservoir and tend to increase intraoral fluoride levels. Nevertheless, the literature is not uniform and some have a short follow-up.
