Mecanismos antibacterianos y biocompatibilidad de los cementos de ionómero de vidrio, posibles aplicaciones

Abstract

Streptococcus mutans is the bacterial species best associated to fossa and fisures caries in humans. This organism is part of the dextran development, wich helps the bacterial plaque to gather and organize. It also produce acids when the ingesta carbohidrates unfold during the desmineralization process of the dental surface. The restoring materials may influence the amount of S. mutans in the plaque and may also effect its adhesion to the dental substrate. This may be evidences by the glass ionomer cements, characterized by their constant fluor release. The glass ionomer cements provide great protection against caries attack. They could, therefore, be the ideal material for patients with active caries and high rates of carious recurrence. The antimicrobiological properties are known forthe material. However, theacting mechanism have never been completely clarified. This article summarizes the main theories know regarding biocompatibility and the antibacterial mechanism s proposed for glass ionomer cements.
