The aim of this study was to identify the risk factors for periodontal disease progression by individual characteristics at baseline among elderly people over a 2-year period. Subjects were selected from 4542 people aged 70 years residing in Niigata who were in good general health and who did not require special care for their daily activities. Gender,(More)
OBJECTIVE Bone loss is a common feature of periodontitis and osteoporosis. Both diseases may share common etiologic agents which may either affect or modulate the process of both diseases. The purpose of this study was to evaluate the relationship between systemic bone mineral density (BMD) and periodontal disease among older people. MATERIALS AND METHODS(More)
The aim of this longitudinal study was to investigate the association between the change in bone mineral density (BMD) and tooth loss in Japanese community-dwelling postmenopausal women. The subjects were 404 women. At baseline (2005) and follow-up (2010), BMDs of the lumbar spine and right femoral neck were measured using dual-energy X-ray absorptiometry(More)
OBJECTIVE Fish oil has anti-inflammatory actions that may benefit periodontal health. We investigated the longitudinal relation between dietary ω-3 fatty acids (FAs), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) to periodontal disease in community-dwelling elderly. METHODS Fifty-five participants aged 74 y were randomly selected from a(More)
OsCERK1 is a rice receptor-like kinase that mediates the signal of a fungal cell wall component, chitin, by coordinating with a lysin motif (LysM)-containing protein CEBiP. To further elucidate the function of OsCERK1 in the defense response, we disrupted OsCERK1 using an Agrobacterium-mediated gene targeting system based on homologous recombination. In(More)
Although an association between SA concentrations and mortality in the patients is well known, this association is not conclusive in elderly community-dwelling populations. We therefore attempted to determine whether this association could be extended to a Japanese 70-year-old community-dwelling population. Seventy-year-old subjects residing in Niigata(More)
AIM To evaluate the relationship between oral bacteria species detection and volatile sulphide compounds (VSC) concentration in the elderly. DESIGN Cross-sectional microbiological and clinical VSC examination of elderly. PARTICIPANTS Sixty-seven elderly people aged 75, who were functionally independent and dentate. METHODS VSC (H2S and CH3SH)(More)
OBJECTIVE The purpose of this cross-sectional study was to evaluate the association between loss of attachment (LA) which is clinical index of periodontitis and bone mineral density (BMD) of the lumbar vertebrae and femur measured with dual energy X-ray absorptiometry (DXA) in Japanese community-dwelling postmenopausal women. SUBJECTS AND METHODS Subjects(More)
The longitudinal relationship between dietary n-6 to n-3 PUFAs ratio and periodontal disease in 235 Japanese subjects for whom data were available for the years 2003-2006 was investigated. PUFAs intake was assessed at baseline with a brief-type self-administered diet history questionnaire. Full-mouth periodontal status, measured as the clinical attachment(More)
BACKGROUND Previous studies have shown conflicting results as to whether low bone mineral density (BMD) is associated with severe clinical attachment loss (AL). The effect of dental restoration on AL was not considered in most studies. In addition, studies of this association in Japanese individuals are limited. The aim of this cross-sectional study is to(More)
