Bacterial colonization patterns of periodontal pockets in different ages.
The aim of this study was to investigate subgingival bacterial composition of untreated Italian subjects with aggressive and chronic periodontitis. The total bacterial load, pathogenic bacteria belonging to "red" and "orange" complexes and Aggregatibacter actinomycetemcomitans were determined by Real-Time PCR in 1216 patients. Data were analysed by looking for relationships between bacteriologi...
متن کاملConjunctival Pockets.
SYMBLEPHARON is described by all authors discussing conjunctival diseases as adhesion between the palpebral and bulbar conjunctivae. Its aetiology is described as purulent conjunctivitis, diphtheritic conjunctivitis, trachoma, trauma, and so on. These factors do not always cause symblepharon, but may result in a very troublesome condition, apparently not mentioned in the literature, viz. conjun...
متن کاملRelationship between oxygen tension and subgingival bacterial flora in untreated human periodontal pockets.
The predominance of anaerobic bacteria in subgingival plaque samples suggests that the pocket environment is anaerobic. In the present investigation, a small oxygen tension (pO2) electrode was inserted into the base of the pocket and the pO2 was recorded. In addition, the plaque in these pockets was examined culturally and microscopically. The oxygen tension at the bottom of 36 pockets (5 to 10...
متن کاملDenaturing gradient gel electrophoresis analysis to study bacterial community structure in pockets of periodontitis patients.
Bacteria are involved in the onset and progression of periodontitis. A promising molecular technique, denaturing gradient gel electrophoresis (DGGE), to study microbial population dynamics in the subgingival pocket is presented. Twenty-three samples were taken from the subgingival pockets of nine patients and six healthy family members. From four periodontitis patients, 12 samples were evaluate...
متن کاملBacterial colonization of polymer brush-coated and pristine silicone rubber implanted in infected pockets in mice.
OBJECTIVES Curing biomaterial-associated infection (BAI) frequently includes antibiotic treatment, implant removal and re-implantation. However, revision implants are at a greater risk of infection as they may attract bacteria from their infected surroundings. Polymer brush-coatings attract low numbers of bacteria, but the virtue of polymer brush-coatings in vivo has seldom been investigated. H...
