Quorum quenching for the management of dental plaque microbes
In the present study, variation among different bacterial strains was observed in the plaques of tobacco chewers (TC) as compared to those from normal persons (non tobacco chewers) (NTC). Bacterial strain J1 (dominant in the plaques of NTC) did not initiate the process of adhesion (biofilm formation) until it appeared to have reached a required population density necessary for the production of...
متن کاملCurrent status of dental plaque
The review deals with global position of the dental plaque, development of dental plaque and species involved and their pathogenicity. Streptococci are the initial colonizers in development of the dental plaque. They attach to the acquired pellicle on tooth surface and later on they show receptors for bonding with the secondary colonizers and late colonizers The conditions leading to the develo...
متن کاملThe structure of dental plaque
Dental plaque has been defined as “the nonmineralized microbial accumulation that adheres tenaciously to tooth surface, restorations, and prosthetic appliances, shows structural organization with predominance of filamentous forms, is composed of an organic matrix derived from salivary glycoproteins and extracellular microbial products, and cannot be removed by rinsing or water spray” (102). The...
متن کاملBacterial sex in dental plaque
Genes are transferred between bacteria in dental plaque by transduction, conjugation, and transformation. Membrane vesicles can also provide a mechanism for horizontal gene transfer. DNA transfer is considered bacterial sex, but the transfer is not parallel to processes that we associate with sex in higher organisms. Several examples of bacterial gene transfer in the oral cavity are given in th...
