Relationship 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 کاملMicroflora cultivable from minocycline strips placed in persisting periodontal pockets.
OBJECTIVE The microflora that develops on minocycline strips, used as an adjunct in non-surgical periodontal therapy was studied. DESIGN AND METHODS Minocycline (1.4 mg in polycaprolactone vehicle) and control strips were applied into all residual pockets (PD > or = 5mm, > or =2 pockets/subject) of patients with chronic periodontitis 1 month after a course of non-surgical periodontal therapy....
متن کاملSubgingival debridement of periodontal pockets by air polishing in comparison with ultrasonic instrumentation during maintenance therapy.
AIM The objective was to determine clinical and microbiological effects and perceived treatment discomfort of root debridement by subgingival air polishing compared with ultrasonic instrumentation during supportive periodontal therapy (SPT). MATERIAL AND METHODS The trial was conducted as a split-mouth designed study of 2-month duration including 20 recall patients previously treated for chro...
متن کاملCorrelation between smoking and severity of periodontal disease in patients with periodontitis in Kerman
Introduction: Periodontitis is a common inflammatory disease of dental supporting tissues caused by bacteria, leading to inflammation, irreversible gum attachment loss, and alveolar bone destruction and eventually tooth loss. While infection is a necessary prerequisite for developing periodontitis, its course and severity depend on a number or factors including inheritance, health behaviors and...
متن کاملMicroflora and periodontal disease
BACKGROUND Periodontitis is a disease that affects and destroys the tissues that support teeth. Tissue damage results from a prolonged inflammatory response to an ecological shift in the composition of subgingival biofilms. Three bacterial species that constitute the red complex group, Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola, are considered the main pathogens inv...
