Intergeneric communication in dental plaque biofilms.
Dental plaque is a complex biofilm that accretes in a series of discrete steps proceeding from a gram-positive streptococcus-rich biofilm to a structure rich in gram-negative anaerobes. This study investigated information flow between two unrelated plaque bacteria, Streptococcus cristatus and Porphyromonas gingivalis. A surface protein of S. cristatus caused repression of the P. gingivalis fimb...
متن کاملDo Dental Resin Composites Accumulate More Oral Biofilms and Plaque than Amalgam and Glass Ionomer Materials?
A long-time drawback of dental composites is that they accumulate more biofilms and plaques than amalgam and glass ionomer restorative materials. It would be highly desirable to develop a new composite with reduced biofilm growth, while avoiding the non-esthetics of amalgam and low strength of glass ionomer. The objectives of this study were to: (1) develop a protein-repellent composite with re...
متن کاملThe Endodontic Microbial Biofilms as An Extension of Dental Plaque, a general hypothesis
Within the last years, and since the inclusion of the biofilm concept in Endodontics, our understanding of root canal infections and the periapical tissues have developed tremendously. Development of new technology and inclusion of novel clinical antimicrobial protocols nowadays rely in the fact that microbial biofilms are formed inside the root canal of teeth and thus these are main targets fo...
متن کاملCommunity analysis of dental plaque and endotracheal tube biofilms from mechanically ventilated patients.
PURPOSE Mechanically ventilated patients are at risk for developing ventilator-associated pneumonia, and it has been reported that dental plaque provides a reservoir of respiratory pathogens that may aspirate to the lungs and endotracheal tube (ETT) biofilms. For the first time, metataxonomics was used to simultaneously characterize the microbiome of dental plaque, ETTs, and non-directed bronch...
متن کاملRespiratory pathogen colonization of dental plaque, the lower airways, and endotracheal tube biofilms during mechanical ventilation.
PURPOSE In mechanically ventilated patients, the endotracheal tube is an essential interface between the patient and ventilator, but inadvertently, it also facilitates the development of ventilator-associated pneumonia (VAP) by subverting pulmonary host defenses. A number of investigations suggest that bacteria colonizing the oral cavity may be important in the etiology of VAP. The present stud...
