Oral mucositis (OM) in cancer patients induced by chemotherapy or radiotherapy has a significant impact on quality of life, and causes considerable morbidity. Oral microorganisms are likely to intensify the inflammatory process and aggravate the formation of ulcers. Hangeshashinto (HST), a Japanese kampo medicine, has been reported to be effective when used as a gargle for the treatment of OM. ...

Necrotic dental root canal infections are polymicrobial infections dominated by anaerobic bacteria. The number of different species in one canal is usually low, approx. 4-7 species. The species isolated most frequently belong to the genera Prevotella, Porphyromonas, Fusobacterium, Peptostreptococcus, Eubacterium and Streptococcus. The frequency of isolation of black-pigmented Gram-negative anae...

The aim of this study was to use the fluorescence in situ hybridization (FISH) technique to test the hypothesis of qualitative and quantitative differences of 8 periodontopathogens between pregnant and non-pregnant women. This cross-sectional study included 20 pregnant women in their second trimester of pregnancy and 20 non-pregnant women. Probing depth, bleeding on probing, clinical attachment...

OBJECTIVE To assess and compare salivary periodontopathic bacteria between groups of Down syndrome and non-Down syndrome children and adolescents. MATERIALS AND METHODS This study included a sample of 30 Down syndrome children and adolescents (G-DS) and 30 age- and sex-matched non-Down syndrome subjects (G-ND). Clinical examination determined the gingival bleeding index (GBI) and plaque index...

OBJECTIVE To investigate whether there is scientific evidence to support the hypothesis that the presence of orthodontic fixed appliances influences the oral microbiota. METHODS The search for articles was conducted in PubMed; ISI Web of Knowledge and Ovid databases, including articles published in English until May 17th, 2012. They should report human observational studies presenting the fol...

The composition of the gut microbiota represents an early indicator chronic post-radiation outcomes in elderly bone and gastrointestinal homeostasis. Fecal analyses revealed that relative abundances Bacteroides massiliensis, Muribaculum sp., or Prevotella denticola were different between conventional (CM) anti-inflammatory restricted (RM). murine RM was found conditional on mucosa-associated dy...

Background/Aim. Periodontal tissue maintenance therapy is an important phase of the overall periodontal disease therapy. This paper aims to determine subgingival air-polishing efficacy with glycine powder in putative paropathogens reduction, plaque index, gingival bleeding index and probing depth. Methods. The study included 44 patients aggressive periodontitis both sexes, aged between 21 50, d...

Equine periodontal disease (EPD) is a painful oral inflammatory syndrome characterized by multifactorial pathogenesis. Although it well known that bacterial proliferation and consequent gingivitis are caused the decomposition process of food residues, in hypsodont species, pathogenetic role different species involved progression EPD must be fully clarified. This study aimed to investigate assoc...

Periodontal disease encompasses gingivitis and periodontitis is one of the most common chronic infections in adult population. This study aimed to evaluate influence Spanish propolis extract (EEP) on effect clinical microbiological parameters as an adjuvant scaling root planning patients undergoing supportive periodontal therapy (SPT). Forty were randomly assigned into two groups for treatment....

We reported previously that Treponema denticola, one of the periodontal pathogens, suppresses the expression of human beta-defensins (HBDs) in human gingival epithelial cells. To identify the mechanisms involved in this suppression, immortalized and normal human gingival epithelial cells were infected with live or heat-killed T. denticola for 24 h, and then the expression of HBDs was examined b...
