n. 1. Sample Collection. 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.

Subgingival plaque collection

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. subgingival plaque synonyms, subgingival plaque pronunciation, subgingival plaque translation, English dictionary definition of subgingival plaque. n.

Subgingival microbial profile associated with periodontitis has been reported to significantly differ by geographical location. The purpose of this study was to assess the association between a panel of putative periodontal bacterial pathogens and chronic periodontitis among Yemenis. Subgingival DNA samples were obtained from diseased and healthy sites of 20 non-smoking, moderate to severe

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.

plaque demonstrated columnar ar-rangement of morphologically distinct bacterial species from the tooth surface to the outer surface of the plaque (Listgarten et al. 1975). Subgingival plaque was frequently characterized by a zone of gram negative and/or motile species located adjacent to the epithelial lining of the pocket while gram positive

However, the collection of saliva is simple and contains pathogens of all intraoral surfaces. The aim of this study is to investigate whether a sampling strategy with mouthrinse (mouthrinse sample [MSP]; test) leads to results 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 plastic tubes during the final 5 min. Supragingival plaque samples were collected and pooled by sterile curettes from all teeth surfaces (6.5 ± 0.9 teeth), on the side of the upper half-jaw that contained the most teeth. Subgingival plaque samples were collected and pooled from gingival crevices of the same region by sterile curettes. The purpose of subgingival scaling and root planing is to remove calculus and to smooth the cementum and underlying dentin. This then allows for effective subgingival plaque removal by the patient, which if done daily will help to prevent calculus formation (calculus removal will be discussed in detail in Chap. 5).

However, the collection of saliva is simple and contains pathogens of all intraoral surfaces. 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.

Similarly, the presence of subgingival plaque containing gram-positive bacteria may be necessary for its secondary colonization in periodontal pockets. View Show abstract 2015-04-01 · This study suggests subgingival plaque sample collection with curette in order to reduce the uptake of human cells and to restrain the sequencing of human DNA in metagenomic studies performed in high-throughput sequencing platforms.

However, recently, 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 The purpose of subgingival scaling and root planing is to remove calculus and to smooth the cementum and underlying dentin.

Clinical assessments by supragingival plaque (PL+), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL) and subgingival plaque collection for microbiological analysis were made prior to and after treatment.

30 May 2019 Supragingival dental plaque was collected from 1 carious active site (when present) and 1 noncarious tooth site (caries-free) from all participants. 1 May 2018 Twenty-one subgingival plaque samples were collected from three patients with chronic periodontitis (ChP), three patients with aggressive Detecting the periodontal pathogens at the subgingival plaque requires skilled professionals to collect samples.

Microbial analysis of subgingival plaque samples compared to that of whole saliva in patients with periodontitis2014Ingår i: Journal of Periodontology, ISSN

2017-06-02 · The subgingival plaque was collected by inserting a sterile dental curette or sterile paper points into the bottom of the gingival crevice . The primary outcome measure was the frequency of periodontopathogen in the subgingival plaques, which referred to the percentage of the patients or teeth positive for periodontopathogens. Sample collection, DNA extraction, library prep, and sequencing. Plaque sample collection and DNA extraction were conducted as specified in reference 27.

Abstract. Background: The collection of subgingival plaque samples with paper points is time-consuming and accident-sensitive. However, the collection of saliva

Technically, local environmental changes related to orthodontic band and brackets may influence the bacterial species in periodontal plaque.

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 Subgingival microbial profile associated with periodontitis has been reported to significantly differ by geographical location.
