Subgingival plaque in deep periodontal pockets

gram-negative microorganisms. This study has shown several potential microbial associations in the subgingival plaque flora of deep periodontal pockets.(ABSTRACT TRUNCATED AT 250 WORDS) View Show abstract We developed a highly sensitive and specific method to detect and quantify cultivable oral treponemes (Treponema denticola, Treponema vincentii, and Treponema medium) in 50 subgingival plaque samples from 13 healthy subjects as well as 37 patients with periodontal diseases using real-time PCR assays with specific primers and a TaqMan probe for each 16S rRNA sequence. OBJECTIVES: To evaluate the microbial composition of deep periodontal pockets at baseline, 1 week, 3 and 12 months after scaling and root planing and the clinical effects of the treatment. The effect of supragingival plaque control on the subgingival microflora. Kho P, Smales FC, Hardie JM. The effect of plaque control on the apical microflora of deep periodontal pockets was studied. 8 subjects exhibiting signs of chronic periodontitis were chosen for the study, each subject having at least one pocket greater than 6 mm. In the presence of supragingival plaque (Group A), however, a subgingival microbiota containing large numbers of spirochetes and motile rods was soon (4–8 weeks) reestablished.

of subgingival debridement in deep pockets (≥ 5 mm) was 0.64 mm while PPD reduction was 1.18 mm and clinical attachment gain was 0.74 mm.

The effect of mechanical supragingival plaque control on the composition of the subgingival microflora in untreated 4‐6 mm deep periodontal pockets was investigated. 13 subjects with chronic periodontitis were recruited for the study. Periodontally‐diseased sites were subjected to professional plaque control 3 × weekly for a period of 3 weeks.

In each of the four quadrants, subgingival plaque samples were collected from one periodontal pocket at baseline, 1 week, 3, and 6 months after the treatment. Two samples from each patient were collected from medium pockets (4– 6 mm) and two samples from deep pockets (>6 mm). Plaque samples were collected with sterile paper points after the The 4 deep periodontal pockets in each patient were assigned to be irrigated with 150 ml CHX (0.12%), TTC (10 or 50 mg/ml; TTC10, TTC50), or sterile saline (control) in a single episode. Post-irrigation mechanical plaque control was supported by 2x daily CHX rinses throughout the 12 … When a periodontal pocket measures 4-5 mm deep or less, the pocket can be adequately cleaning without opening a surgical flap.

Subgingival plaque in deep periodontal pockets

3 Mar 2016 the pocket in medium and deep periodontal pockets penetrated farther from subgingival plaque and was reported to be between 8 and 500

Methods English-language databases (PubMed, Cochrane Central Register of Controlled Trials, EMBASE, Medline, and Subgingival application of both the oils was performed following initial SRP and at 7, 14, and 21 days. Clinical parameters including probing pocket depth (PPD), plaque index (PI), and gingival index (GI) were measured. Plaque samples from periodontal pockets were obtained with sterile paper points at baseline and 1 month for anaerobic culture. Introduction to periodontal Pocket. The periodontal pocket is a pathologically deepened gingival sulcus due to the apical migration of junctional epithelium.

A probe-type tip has been newly designed for Out of 255 subgingival samples, A.actinomycetemcomitans cdtB was detected in 126 (49.4%) samples. In the 71 subgingival samples from periodontal healthy individuals, none of the samples were cdtB positive (Table 3). While 54 of the 73 (74.0%) A.actinomycetemcomitans positive subgingival plaque samples from CP patients were cdtB positive. A study was made to determine if the numbers of subgingival anaerobes in deep periodontal pockets can be controlled by removal of only supragingival plaque. The study was based on the premises that the subgingival flora is dependent on the supragingival plaque for its source of organisms as well as for its perpetuation. Repeated subgingival air-polishing with erythritol powders in non-resolving sites during periodontal maintenance resulted in the reduction of the number of deep pockets similar to ultrasonic debridement procedures leading to a lower detection of Aggregatibacter actinomycetemcomitans [26].

The goal of periodontal therapy is to decrease the size of or eliminate pockets in cases of early and moderate periodontal disease by removing subgingival plaque and calculus, using locally applied antimicrobials, performing gingivectomy, or extracting the affected teeth. Microbial Etiology of Periodontal Disease, Dr. Lee 9 Spirochetes G (-), anaerobic, spiral, highly motile ANUG Increased numbers in deep periodontal pockets Difficulty in distinguishing individual species 15 subgingival spirochetes described Obscure classification - Small, medium, or large T. denticola Indeed, previously presented evidence shows a phylogenetic similarity or co-occurrence pattern of specific periodontal pathogens between supragingival and subgingival plaque 31,32,33.

Periodontal pocket may be considered as a healing lesion. As stated above, periodontal pocket formation primarily has bacterial etiology. The goal of periodontal therapy is to decrease the size of or eliminate pockets in cases of early and moderate periodontal disease by removing subgingival plaque and calculus, using locally applied antimicrobials, performing gingivectomy, or extracting the affected teeth.

Plaque samples were collected with sterile paper points after the Objectives: Denaturing gradient gel electrophoresis (DGGE) was applied to the microbiologic examination of subgingival plaque. Materials and methods: The PCR primers were designed from conserved nucleotide sequences on 16S ribosomal RNA gene (16SrDNA) with GC rich clamp at the 5'-end. Search term.
