Collection of subgingival plaques Subgingival plaquesampleswerecollectedby asterile hand scalerandtransferred ineither one ml of sterile reduced transfer fluid (RTF) consisting of 0.01% dithiothreitol in PBS, pH 7.4 or one ml of distilled water. The samples were immediately placed at 4 C and analyzed within 4 h. Subgingival plaque samples from 259 adult patients with severe periodontitis were analyzed. P. gingivalis was detected in 111 (43%) of the 259 subgingival plaque samples by culture and in 138 (53%) samples by PCR. The sensitivity, specificity, and positive and negative predictive values of the real-time PCR were 100, 94, 94, and 100%, respectively. Define subgingival plaque.

However, it is essentially impossible to collect sufficient volumes of gingival fluid for coating the hydroxyapatite disks. For this reason, we elected to use unstimulated saliva.

Subgingival plaque samples were collected as described in [35]. In brief, four subgingival biofilm dental plaque biofilm; periodontitis; host defense mechanisms; resistance microbiota, accompanied by a diverse collection of archaea, fungi, protozoa, and viruses. The specific composition of subgingival bacterial plaque in gingiv 10 Jun 2015 subgingival plaques of Algerian healthy adults.
Subgingival plaque sample collection. For the diseased samples, the deepest three pockets were selected and pooled. Supragingival plaque was first removed from the sample teeth with sterilized Gracey curettes and gauze. The site was then cleaned and isolated using cotton roles and air dried gently.
A total of 1,170 samples of supra and subgingival plaque were collected from the mesial aspect of every tooth (up to 28 supra and 28 subgingival samples) from each subject and evaluated for the was followed by collection of a pooled subgingival sample, collected from four sites with the deepest PD using the curette technique.26 Subgingival plaque samples were suspended in sterile saline (500 𝜇l).
Buccal and subgingival plaque samples were collected 1 week after the full-mouth periodontal examination. All participants were requested to refrain from food for 8 h and oral hygiene (brushing or flossing the teeth) for 12 h before sampling. Samples from all subjects were collected and stored at −80°C for subsequent
Plaque absorbs calcium and phosphate from saliva for the formation of supragingival calculus and from crevicular fluid for the formation of subgingival calculus. Calcium phosphate supersaturation, certain membrane-associated components, and the degradation of nucleation inhibitors are required for initial mineralization of plaque and bacteria. Pooled subgingival plaque samples were collected and analyzed for detection of bacteria and viruses using loop‐mediated isothermal amplification. Prevalence of subgingival A. actinomycetemcomitans , HCMV, and P. gingivalis were significantly higher among aggressive periodontitis patients than periodontally healthy controls.

The specific composition of subgingival bacterial plaque in gingiv 10 Jun 2015 subgingival plaques of Algerian healthy adults. Supragingival and subgingival plaque samples were collected from 65 Algerian caries-free, for diagnostic quantitative anaerobic culture of subgingival plaque samples.
Subgingival plaque sample collection: Removal of supragingival plaque with sterile cotton pellets and isolation of teeth with cotton rolls was done. Subgingival plaque was then collected with sterile paper points (Meta Biomed ® Co. Ltd, Cheongju, South Korea) inserted into the gingival sulcus of Ramfjord’s index teeth for 15 seconds(7-9).
