Food rely on mechanical digestion and chemical digestion and absorption of nutrients. The first hurdle is full of chewing in the oral cavity by mechanical digestion and chewing food and saliva mixed chemical digestion, and then swallowing to the stomach, and rely on gastric and intestinal digestion and absorption. Poor oral hygiene, some pathogenic bacteria will multiply in the stomach. Studies have shown that gastritis is caused by a bacterium detected in dirty oral plaque bacteria, the drug is easy to clear the stomach of Helicobacter pylori, Helicobacter pylori in dental plaque is difficult to remove become bacteria library.
Of oral disease pathogens and toxins can invade the blood, can produce the relevant antibody, lectin, aggravated or caused by subacute infective endocarditis, coronary heart disease. Numerous studies confirm that periodontitis is an independent risk factor for coronary heart disease with acute exacerbation, with acute onset or total mortality are significantly correlated.
Cerebrovascular diseaseMyocardial infarction and coronary heart disease and periodontitis induced, periodontitis can induce ischemic stroke. Periodontitis risk factors for stroke, coronary heart disease and myocardial infarction. Studies have shown that periodontitis as a stroke risk factor than smoking, independent of other known risk factors.
Oral diseases associated with aspiration pneumonia due to all causes strong. According to statistics, 80 percent of the incentive, pneumonia inhalation of oral and pharyngeal secretions containing bacteria, and these secretions are mostly from the oral cavity.
