    The dominant bacterial species in dental plaque are Streptococcus sanguis and Streptococcus mutans, both of which are considered responsible for plaque. Streptococcus mutans. Gram stain. CDC. Plaque formation is initiated by a weak attachment of the streptococcal cells to salivary glycoproteins forming a pellicle on the surface of the teeth.   Grooves on the occlusal surfaces of molar and premolar teeth provide microscopic retention sites for plaque bacteria, as do the approximal sites. Plaque may also collect above or below the gingiva where it is referred to as supra- or sub-gingival plaque respectively. Figure: Gram stain of Streptococcus mutans.

    • Antimicrobial Mouth Rinse reduces oral streptococcal bacterial eco-sytem associated with caries and plaque formation • Supports remineralization of teeth enamel, rebuilds weak spots, protects teeth from acid/wear erosion and prevents tooth decay • Minimal staining / Alcohol free. By using in vitro assays, a group of related, filamentous gram-negative bacteria isolated from subgingival plaque deposits of patients with periodontal disease were found to colonize intact teeth. Tentatively identified as members of the genus Cytophaga, these isolates exhibited a preference for colonizing the cementum surface of the root.

Periodontal disease is the general description applied to the inflammatory response of the gingiva and surrounding connective tissue to the bacterial or plaque accumulations on the teeth. These inflammatory responses are divided into two general groupings: gingivitis or periodontitis.

Gingivitis is extremely common, and is manifested clinically as bleeding of the gingival or gum tissues without evidence of bone loss or deep periodontal.

Studies of the mechanism of sucrose-associated colonization of Streptococcus mutans on teeth of conventional by: Dental plaque is a complex biofilm that accumulates on the hard tissues (teeth) in the oral cavity.

Although over bacterial species comprise plaque, colonization follows a regimented pattern with adhesion of initial colonizers to the enamel salivary pellicle followed by secondary colonization through interbacterial by: The mechanism of plaque formation is believed to involve the attachment of Streptococcus mutans to the surfaces of teeth and their subsequent colonization.

One per cent (w/v) solutions of the organic fraction of methanol extract of G. kola fruit, kolaviron, or GB-1 were found to be effective in inhibiting the attachment of clinical isolate of S. mutans to glass or saliva-coated hydroxy-apatite beads. Formation of Dental Plaque • Dental plaque may be readily visualized on teeth after 1 to 2 days with no oral hygiene measures.

Plaque is white, grayish, or yellow and has a globular appearance. • Movement of tissues and food materials over the teeth results in mechanical removal of plaque on the coronal two thirds of the tooth Size: 1MB. The composition of the streptococcal flora on the dentures was similar to that previously found on teeth.

The accumulated evidence on the ecology of Streptococcus sanguis and Streptococcus mutans indicate that these streptococci can only be established in the mouth if solid surfaces such as on teeth and dentures are by: Formation of supragingival dental plaque. Within minutes after a tooth surface is freshly cleaned, an acquired pellicle, composed primarily of salivary proteins, is adsorbed to the exposed hy- droxyapatite crystallites (4, 20, 69,).File Size: 2MB.

Streptococcus mutans has a high association with dental caries. It has been shown, however, that colonization of teeth does not take place in the absence of dietary sucrose. The organism utilizes sucrose to produce polysaccharides, such as dextran, a complex extracellular polysaccharide, and glycoproteins.

These polysaccharides enable the. We investigated the ability of Streptococcus mutans C to colonize simple bacterial plaques and the effects of age and stability of the pre-formed plaque on colonization resistance.

This article focuses on the adherence and colonization properties of selected members of the genus Streptococcus, particularly from the perspective of community ia in the natural environment often grow upon surfaces, and it is thought that many species of streptococci that colonize mammals exist naturally within communities of bacteria growing Cited by: The aim of this study was to estimate differences in the prevalence of oral streptococcal species in the subgingival biofilm of patients with aggressive periodontitis and of healthy controls.

Thirty-three patients with clinical and radiological proof of aggressive periodontitis and 20 healthy subjects were enrolled in this study. Clinical indices were recorded in a six-point measurement per by: The salivary pellicle is an organic film derived from the saliva and deposited on the tooth surface.

It is, however, rapidly colonized by bacteria which make up the dental plaque. Based on the dental plaque's relationship to the gingival margin, it has been separated for microbiological studies into two different communities: supragingival and subgingival plaque.

Lactobacillus acidophilus, L. casei and L. fermentum could not form plaques alone, but could do so in conjunction with Streptococcus mutans or Strep. the plaques develop the proportions between lactobacilli and streptococci changed so that in a mixed plaque, which contained initially all the organisms, only L.

albicans partners with Streptococcus gordonii, S. oralis, and S. sanguinis to enhance bacterial colonization and biofilm formation. In addition, C. albicans becomes more invasive, exacerbating mucosal tissue infection and destruction [8,9].

Mixed by:. Dental caries and periodontal disease are closely associated with dental plaque, the biofilm that results from microbial colonization of the tooth surface. Various experimental models have been described for the initial phase of colonization, including one that utilizes enamel chips positioned within the oral cavity for periods of time up to   The aim of this study was to identify the bacterial species important in the early stages of canine plaque formation in vivo and then use isolates of these species in a laboratory biofilm model to develop an understanding of the sequential processes which take place during the initial colonization of enamel.
