Gingival recession is common in many patients, and generally is associated with periodontal disease, inadequate toothbrushing, and repeated periodontal instrumentation, among other etiologies. Gingival recession as a consequence of regular toothbrushing has been reported, and can be observed even in young populations with well-established habits of oral hygiene. Gingival recession also is assoc...

The subgingival bacterial floras of naturally occurring gingivitis in adults and children were characterized and compared with the floras of other periodontal conditions previously studied. The composition of the gingivitis floras was found to be distinct from that of floras associated with health or with moderate, severe, or juvenile periodontitis. There were no major differences between the f...

Lowering of interstitial fluid pressure (P(if)) is an important factor that explains the rapid edema formation in acute inflammation in loose connective tissues. Lipopolysaccharide (LPS) and the pro-inflammatory cytokines interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) are pathogenetic in gingivitis. To test if these substances induce lowering of P(if) in rat oral mucos...

The plaque flora isolated from discrete dentogingival sites during a human gingivitis experiment was analyzed as a function of the plaque score and of the gingivitis score. When the gingivitis score was plotted as a function of the plaque score, a nonbleeding gingivitis was associated with a proportional increase in the Actinomyces sp. at the expense of the Streptococcus sp. In particular, the ...

Serum samples obtained from 59 persons who had acute necrotizing ulcerative gingivitis, periodontitis, syphilis, or Lyme disease were tested against Treponema phagedenis biotype Reiter, Treponema denticola, Treponema vincentii, and Treponema scoliodontum by indirect fluorescent-antibody staining methods. Although there were positive reactions for sera representing each of these study groups and...

BACKGROUND AND AIM: Gingivitis is a reversible inflammation of gingival tissue. The prevalence of gingivitis is different in various communities. The aim of this study was to determine the prevalence of gingivitis among 6-year-old (± 3 months) children of Rayen, Kerman, Iran.METHODS: In this cross sectional study, 279 children (129 boys and 150 girls) from all Rayen’s nursery schools and primar...
