Abstract(s)
As bactérias que vivem na cavidade oral constituem o bio-filme oral. Os ácidos produzidos por certas bactérias criam um ambiente favorável para o desenvolvimento de estirpes cariogénicas e do bio-filme, que em seguida provocam um desequilíbrio entre os processos de desmineralização e de remineralização do tecido dentário, dando origem à cárie. Neste trabalho examinaremos sobretudo a espécie S. mutans e os seus processos metabólicos de adesão, colonização e proliferação que utilizam os nutrientes presentes na cavidade oral para produzir os ácidos que originam as cáries. Resultados mais recentes permitem-nos aprender mais sobre a complexidade destes metabolismos bacterianos, incluindo a adaptabilidade dos S. mutans ou a sua relação sinérgica com outras espécies. Esta literatura fornece informações sobre a capacidade dos S. mutans de substituir a glicose por sorbitol, a fim de evitar a produção de ácido, o que abre o caminho para um potencial tratamento preventivo eficaz.
Bacteria living in the oral cavity form the oral bio-film. Acids produced by certain bacteria create a favourable environment for the development of cariogenic strains and the bio-filme, which then cause an imbalance between the demineralisation and remineralisation processes of the dental tissue, giving rise to caries. In this work we will examine in particular the species S. mutans and its metabolic processes of adhesion, colonisation and proliferation which use the nutrients present in the oral cavity to produce the acids that cause caries. More recent results allow us to learn more about the complexity of these bacterial metabolisms, including the adaptability of S. mutans or its synergistic relationship with other species. This literature provides information about the ability of S. mutans to replace glucose with sorbitol in order to avoid acid production, which opens the way to a potential effective preventive treatment.
