INTRODUCTION Orthodontic appliances hinder mechanical plaque control. In this study, we evaluated the effect of self-performed supragingival plaque removal with ultrasonic, electric, and manual toothbrushes on subgingival plaque composition in orthodontically banded molars. METHODS Twenty-one patients wearing fixed orthodontic appliances were assigned to this single-blind crossover study. Sam...

A NOXIA is known to induce a biphasic effect on blood flow to the extremities. In anesthetized dogs, there is a decrease in blood flow to the leg during anoxia but this is immediately followed by an increase during reoxygenation. 1-3 Since thermoelectric methods have been used for recording blood flow, it has not been possible to express the vascular responses quantitatively to the same extent ...

In this study, we compared a new, rapid DNA-probe assay sample) of each species by using the total anaerobic count for each sample. with anaerobic culture for characterizing the microbiology Five healthy sites and five gingivitis sites from selected of initial periodontal lesions in adults. We used the microbisubjects were sampled for DNA-probe analysis with 13 probes ological data from both as...

Periodontitis is a polymicrobial disease caused by complex interactions between distinct pathogens in a biofilm resulting in the destruction of periodontal tissues. It seems evident that unknown microorganisms might be involved in onset or progression of periodontitis. For many decades, research in the field of oral microbiology failed to identify certain subgingival microbiota due to technical...

It has been recognized for some time that bacterial species exist in complexes in subgingival plaque. The purpose of the present investigation was to attempt to define such communities using data from large numbers of plaque samples and different clustering and ordination techniques. Subgingival plaque samples were taken from the mesial aspect of each tooth in 185 subjects (mean age 51 +/- 16 y...
