Introdução: Os selantes de fissura são um meio eficaz atualmente aceite na prevenção ou controlo da cárie dentária, sendo os de resina composta e os de cimento de ionómero de vidro (CIV) os mais usados. Objetivo: Realizar uma revisão narrativa da literatura relativamente à aplicação de cimento de ionómero de vidro de elevada viscosidade utilizado como selante de fissura na prática clínica do médico dentista, suas indicações, vantagens e longevidade. Metodologia: Foi realizada uma pesquisa nas bases de dados PubMed, EBD, Cochrane Library, BVS e SciELO, até março de 2017, e com a combinação dos seguintes termos: “Pit and Fissure Sealants” AND “Glass Ionomer Sealants” e “ART Sealants”. Os artigos foram selecionados de acordo com os critérios de inclusão/exclusão definidos e através da leitura dos seus títulos e resumos. Desenvolvimento: Apesar de os selantes de resina composta serem o gold standard, em algumas situações a sua utilização pode não ser vantajosa. Os CIVs têm várias vantagens como o facto de serem menos sensíveis à humidade, o que poderá constituir uma alternativa ao rigor da técnica exigida pelos selantes de resina composta, e de possuírem um potencial de libertação de flúor, fazendo destes materiais um possível aliado na prevenção da cárie dentária. Os selantes ART, constituídos por CIV de elevada viscosidade e assim designados devido à similaridade de aplicação descrita na Técnica Restauradora Atraumática (ART), têm sido estudados, podendo constituir uma alternativa aos selantes de resina composta. Conclusão: Os selantes de CIV de elevada viscosidade, indicados em condições de campo ou quando se espera um controlo de humidade deficitário, possuem um potencial libertador de flúor entre outras vantagens, tendo apresentado resultados encorajadores quanto à prevenção da cárie dentária a curto prazo. Contudo, por serem poucos os trabalhos que os avaliam a longo prazo, salienta-se a importância da realização de mais estudos sobre esta temática. Introduction: Pit and fissure sealants are an effective measure currently accepted in the prevention or control of dental caries, with composite resin and glass-ionomer cement (GIC) being the most commonly used materials.
Objective: To carry out a narrative review of literature regarding the application of high-viscosity glass-ionomer cement, used as a fissure sealant in clinical practice, its indications, advantages and longevity. Methodology: A search was made in PubMed, EBD, Cochrane Library, BVS and SciELO databases by until March 2017, with the following terms: “Pit and Fissure Sealants” AND “Glass Ionomer Sealants”, and “ART Sealants ". Articles were selected according to the defined inclusion / exclusion criteria by reading their titles and abstracts. Development: Although composite resin sealants are the gold standard, in some situations their use may not be advantageous. GICs have several advantages such as being less sensitive to moisture. which may be an alternative to the rigor of the technique required by composite resin sealants, and a potential for fluoride release, which makes these materials a possible ally in prevention of dental caries. The ART sealants, made up of high-viscosity GIC and so called due to the similarity of application described in the Atraumatic Restorative Technique (ART), have been studied and may be an alternative to composite resin sealants. Conclusion: High-viscosity GIC sealants, indicated under field conditions and when poor moisture control is expected, have fluoride releasing potential among other advantages and have shown encouraging results in the prevention of dental caries in the short term. However, because there are few studies that evaluate the long-term performance of these materials, it is important to carry out further studies on this topic.
