Subgingival plaque samples were taken from the mesial aspect of each tooth in 185 subjects (mean age 51 ± 16 years) with (n= 160) or without (n= 25) periodontitis. The presence and levels of 40 subgingival taxa were determined in 13.261 plaque samples using whole genomic DNA probes and checkerboard DNA‐DNA hybridization.

Bacterial phyla identified from subgingival plaque. Nine bacterial phyla were represented from clonal analysis. As shown, the first two phyla, Obsidian Pool OP11 and TM7, have no cultivable representatives. Oral members of the phylum Deferribacteres form a cluster consisting of only not-yet-cultivated phylotypes. The information presented in Fig. 1 to 7 includes bacterial species or phylotype, strain or clone identification, sequence accession number, total number of retrieved clones, and

The secondary purpose was to obtain qualitative data on the diversity of bacteria in different periodontal disease states and periodontal health. This study reports on the analysis of 2,522 16S rRNA sequences, thus Subgingival plaque was sampled with a gas flushed broach passed through a syringe. Significance of differences in viable recoveries was determined by ANOVA. Brewer jars and chamber (aerobic plating) were comparable in efficiency, but excelled roll tubes (anaerobic inoculation). TS was better than B, but equivalent to MM 10. The effects of phenoxyethanol, chlorhexidine and a mixture of both on subgingival plaque samples from 44 patients with chronic periodontitis were investigated in vitro. At a concentration of 0.5 mg/ml, chlorhexidine inhibited the growth of all cultivable bacteria in all 44 samples while a comparable effect was achieved with phenoxyethanol only at a concentration of 20 mg/ml.

Se hela listan på cced.cdeworld.com Supragingival plaque biofilm is deposited on the clinical crowns of the teeth, whereas subgingival plaque biofilm is located in the gingival sulcus or periodontal pocket. Small amounts of supragingival plaque biofilm are difficult to detect clinically without placing a disclosing solution or dye on the teeth, or scraping the tooth surfaces with an instrument. 2017-04-03 · In this study, we focused on subgingival plaque-specific bacteria that were particularly predominant in subgingival plaque compared to those in other oral niches. We assumed that the relative abundance of subgingival plaque-specific bacteria in saliva would be useful to monitor the overall periodontal condition easily and noninvasively, regardless of heterogeneous clinical conditions. Subgingival plaque samples from 20 patients with chronic periodontitis who had received no antibiotics for at least 3 months were screened for the presence of P-lactamase-producing bacteria. Thirteen of the patients harboured P-lactamase producing bacteria, most of which were members of the genus Bacteroides.

Once calculus forms, it then attracts more plaque, which in time can become another layer of calcified material. Characteristics of Subgingival Calculus Detection and Quanti cation of Subgingival Plaque Bacteria .

Bacterial diversity in human subgingival plaque. J Bacteriol 2001;183:3770-83. 32. Socransky SS, Haffajee AD. Dental biofilms: difficult therapeutic targets.

The collection of subgingival plaque samples is the common way for the determination of periodontopathic bacteria. However, recently, salivary analysis has been discussed as an advantageous future diagnostic method for periodontitis because it offers simple quantitative sampling and the possibility to assess various bacteria.

plaque control of the patient and thereby facilitated formation titis, result from the formation of bacterial deposits on implant subgingival plaque formation in.

Thirteen of the patients harboured P-lactamase producing bacteria, most of which were members of the genus Bacteroides. Using shotgun sequencing, we constructed a genome encyclopedia describing the core supragingival plaque microbiome. This unveiled several new previously uncharacterized but ubiquitous microbial lineages in the oral microbiome. diversity of bacteria in human subgingival plaque by using culture-independent methods. The secondary purpose was to obtain qualitative data on the diversity of bacteria in different periodontal disease states and periodontal health. This study reports on the analysis of 2,522 16S rRNA sequences, thus Subgingival plaque was sampled with a gas flushed broach passed through a syringe. Significance of differences in viable recoveries was determined by ANOVA.

table 1. The mean of optical density 0.5–0.7% tetracycline gel toward subgingival plaque bacteria Treatment Subgingival plaque was analyzed from healthy subjects and subjects with refractory periodontitis, adult periodontitis, human immunodeficiency virus periodontitis, and acute necrotizing ulcerative gingivitis. 16S ribosomal DNA (rDNA) bacterial genes from DNA isolated from subgingival plaque samples were PCR amplified with all-bacterial or selective primers and cloned into Escherichia coli. The collection of subgingival plaque samples is the common way for the determination of periodontopathic bacteria. However, recently, salivary analysis has been discussed as an advantageous future diagnostic method for periodontitis because it offers simple quantitative sampling and the possibility to assess various bacteria.

For Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia, as well as Actinomyces viscosus, Campylobacter rectus/showae, Prevotella intermedia, Parvimonas micra, Eubacterium nodatum, and Campylobacter gracilis, a significant positive correlation between salivary and subgingival plaque samples was detected in patients with both types of periodontitis. Bacterial profiles of subgingival plaques in periodontitis. Loesche WJ, Syed SA, Schmidt E, Morrison EC. In this report over 400 subgingival plaque samples taken from over 110 patients were examined microscopically and culturally for 30 bacterial parameters. The patients could be placed into six disease categories based upon clinical criteria. Capnocytophaga are gram-negative, facultative anaerobic bacteria. They were the earliest bacteria to be isolated and named from the human subgingival plaque. Common Capnocytophaga species are: Capnocytophaga ochracer, Capnocytophaga sputigena, Capnocytophaga gingivalis, Capnocytophaga granulose, and Capnocytophaga heamolytica.

Calcification times can vary from person to person, depending on their salivary pH and the amount of calcium and other substances in their saliva. Once calculus forms, it then attracts more plaque, which in time can become another layer of calcified material.

Materials and Methods enamel pellicle, and subsequently, filamentous bacteria gradu - ally dominate the maturing plaque biofilm (Scheie, 1994). Plaque absorbs calcium and phosphate from saliva for the formation of supragingival calculus and from crevicular fluid for the formation of subgingival calculus.
