Bacterial interactions in dental biofilm

Peri-Implant Infections of Oral Biofilm Etiology

“…The oral bacteria rarely grow in single planktonic form, but they naturally form biofilm communities with each other on the tooth surface. Biofilms exhibit a very high level of structural and functional bacterial organization, whereby the individual bacterial constituents communicate with each other by finely tuned molecular processes (also defined as "quorum sensing") (Huang et al 2014). …”

“…The dental biofilm is a multispecies community consisting of more than 700 microbial species, and each human mouth may harbour as many as 120 species (Hajishengallis & Lamont, 2012;Huang et al, 2011). Dental biofilm develops in a sequential process with initial colonizers attaching to the tooth surface, followed by early, middle and late colonizers joining via cell-cell co-aggregation (Kolenbrander et al, 2006Zhou et al, 2015b).…”

“…By comparing the isolated bacterial species in caries-active and caries-free groups (Table 1), the predominant bacteria were Streptococcus mutans and Lactobacillus acidophilus in caries-active and caries-free children, respectively. In harmony with this finding, S. mutans strains had considerable interest and have been considered the main etiological agent of dental caries in humans (Huang et al, 2011). On the other hand, Corcuera et al, (Corcuera et al, 2013) stated that, Str.…”

“…This biofilm provides several advantages to the bacteria involved in its formation and for the other bacteria in the same environment. More information about bacterial interactions in dental biofilm and different strategies for control this biofilm are available in elsewhere (Huang et al, 2011;Chandki et al, 2011;Jhajharia et al, 2015). In this respect, nanoparticles of metals (i.e., selenium, silver and zinc) and antimicrobial polymers have gained significant interest over the years due to their remarkable antimicrobial and antibiofilm properties (Melo et al, 2013).…”
