Effect of minocycline on subgingival plaque bacteria

Journal of Applied Bacteriology, 1990
The effects of minocycline on subgingival plaque samples from patients with chronic periodontitis were investigated in vitro. Minocycline concentrations as low as 1.0 μg/ml inhibited 95.7% of the cultivable bacteria in the samples but 256 μg/ml was necessary to inhibit all of the cultivable bacteria in the samples.

Microbial succession in subgingival plaque of man

Journal of Periodontal Research, 1976
A model system allowing study of microbial succession on a single tooth root is described. Three levels of the root were studied: the supragingival surface, an area of the root immediately apical to the gingival margin, and the apical one‐third of the root.

The structure of subgingival plaque in a beagle dog

Journal of Periodontal Research, 1974
The maxillary canines and second and third premolar teeth, together with supporting bone and gingival tissues, were surgically removed from a nine month old Beagle dog. All the gingival units showed clinical signs of gingivitis. At the orifice of the gingival crevice the plaque comprised a dense, mixed bacterial population.

The Effect of Female Sex Hormones on Subgingival Plaque

Journal of Periodontology, 1981
The periodontal status of three groups of women; pregnant, taking oral contraceptives, and nonpregnant, were evaluated clinically and microbiologically for changes in their gingiva and any corresponding changes in the subgingival microbial plaque, specifically the percentage of Fusobacterium species and Bacteroides species.

A new method for assessing the % of spirochaetes in subgingival plaque

Journal of Clinical Periodontology, 1986
Abstract A new method for counting the numbers of spirochaetes in subgingival plaque is described. The technique involves the combined use of a negative stained preparation, dark field microscopy, and an image analysing system. Advantages of the method include: smears need not be made until 2 days after sampling, and can be examined microscopically for

An Histologic Comparison of Supra and Subgingival Plaque and Calculus

Journal of Periodontology, 1971
Supra and subgingival plaque and calculus were col­ lected according to the method described by Oshrain, et al. 1 Sandblasted mylar strips were inserted into pockets 4 mm or more in depth, limited to incisor teeth (Fig. 1). The gingiva of the pockets selected varied in appearance from that of slight inflammation to severe inflammation.

Presence or absence of plaque on subgingival restorations

European Journal of Oral Sciences, 1975
abstract— One hundred and eight extracted teeth with restorations placed below the gingival margin were stained and examined under the stereomicroscope with the aim of scoring presence or absence of subgingival plaque. Individual observations showed that a subgingival restoration can be completely covered with plaque in as short a time as 6 weeks and ...

Effect of Toothbrushing on Subgingival Plaque Formation

Journal of Periodontology, 1981
The purpose of the present study was to find out to what extent subgingival plaque formation may be prevented by toothbrushing. The experiment was carried out on a total of 28 molars in four monkeys. On day 0 all supra‐ and subgingival deposits were removed, and during the following year, the teeth on the left side were carefully brushed three times a ...

Antibiotic susceptibility testing of subgingival plaque samples

Journal of Clinical Periodontology, 1983
Abstract The in vitro inhibitory effect of several antimicrobial agents was determined against dispensed dental plaque samples taken from periodontally diseased sites as an aid in the selection of antibiotics for adjunctive use in periodontal therapy. 2 groups of patients were sampled.

Subgingival plaque microbiota in HIV positive patients

Journal of Clinical Periodontology, 2006
AbstractAim: To describe and compare the predominant bacterial and fungal species associated with gingivitis, periodontitis, and linear gingival erythema (LGE), in HIV positive subjects with different immune status.Methods: Viral loads and CD4 levels determined HIV disease status.
