Abstract(s)
A erosão dentária é um processo contínuo, irreversível e indolor que leva à perda de estrutura dentária por acção de ácidos de origem não bacteriana. A origem dos ácidos pode ser extrínseca (ambiental, alimentação), intrínseca (distúrbios de refluxo gástrico) ou idiopática (etiologia desconhecida).
O aumento da prevalência da erosão dentária em indivíduos jovens, leva a que o diagnóstico deva ser feito o mais precocemente possível. A abordagem passa pela eliminação/controlo dos fatores etiológicos/predisponentes, e pela prevenção que implica a aplicação de compostos fluoretados que aumentam a resistência da estrutura dentária aos ácidos. Os mais frequentemente utilizados são o fluoreto de sódio (NaF), o fluoreto de estanho (SnF2) e o tetrafluoreto de titânio (TiF4).
Com este trabalho de revisão bibliográfica pretendeu-se reunir as principais conclusões dos estudos publicados, sabendo que sem a realização de um tratamento estatístico associado a estudos de meta-análise/ revisão sistemática, não é possível concluir qual o agente ou protocolo de aplicação mais eficaz. Há, no entanto, alguma tendência dos vários autores em considerar o fluoreto de estanho como o agente com maior eficácia, devendo ser aplicado sob forma de gel. Serão necessários mais estudos e com protocolos padronizados, para que se possa confirmar este reforço da estrutural mineral contra o desgaste erosivo.
Dental erosion is a continuous, irreversible and painless process that leads to the loss of tooth structure through the action of non-bacterial acids. The origin of the acids may be extrinsic (environmental, food), intrinsic (gastric reflux disorders) or idiopathic (unknown etiology). The increased prevalence of dental erosion in young individuals leads to a diagnosis that should be made as early as possible. The approach involves the elimination / control of etiological / predisposing factors, and the prevention that implies the application of fluoride compounds that increase the resistance of dental structure to acids. The most frequently aplied are sodium fluoride (NaF), stannous fluoride (SnF2) and titanium tetrafluoride (TiF4). With this bibliographical review work we intend to gather the main conclusions of the published studies, knowing that without the accomplishment of a statistical treatment associated with studies of meta-analysis / systematic review, it is not possible to conclude which agent or protocol of application more effective. There is, however, some tendency of the various authors to consider stannous fluoride as the agent with the greatest effectiveness and it should be applied as a gel. Further studies and standardized protocols will be necessary to confirm this reinforcement of the mineral structure against erosive wear.
