- Periodontitis is caused by microorganisms that adhere to and grow on the tooth's surfaces, along with an over-aggressive immune response against these microorganisms.he 1999 classification system for periodontal diseases and conditions listed seven major categories of periodontal diseases, of which 2-6 are termed destructive periodontal disease because the damage is essentially irreversible. The seven categories are as follows: 1  Gingivitis.

Pathogenic bacteria Some pathogenic bacteria cause disease under certain conditions, such entry through the skin via a cut, through sexual activity or an compromised immune function. Streptococcus and Staphylococcus are part of the normal skin microbiota and typically reside on healthy skin or in the nasopharangeal region.hese pathogens can cause pneumonia or urinary tract infection and may be involved in coronary heart disease. Other groups of intacellular bacterial pathogens include: Salmonella, Neisseria, Brucella, Mycobacterium, Listeria, Francisella, Legionella, and Yersinia pestis.

- Evidence indicates that periodontal disease is an autoimmune disorder triggered by infectious organisms and an abnormal immune response to collagen. Periodontal disease is an inflammatory condition affecting both the gums and the deep structures that house the roots of the teeth.eriodontal disease can cause the teeth to loosen and decay. Individuals with periodontal disease may experience bleeding of the gums when brushing, which is often the first sign of a problem. The gums may also appear swollen and recede away from the teeth.

Understanding Periodontitis: A Progressive Form of Gum Disease Gum disease, also known as periodontal disease, exists in two forms: gingivitis and periodontitis. Both types of gum disease arise from a bacterial infection that is usually brought on by poor dental care. Gingivitis is a milder form of gum disease that causes irritated, bleeding gums.

PATHOGEN SAFETY DATA SHEET - INFECTIOUS SUBSTANCES PATHOGENICITY/TOXICITY: B. pertussis is a respiratory pathogen that causes pertussis, also known as whooping cough, a localized infection of the ciliated epithelium of the bronchial tree. The disease affects mainly children, but adults have also been increasingly reported to be affected.HARACTERISTICS: Bordetella pertussis are small, gram-negative, encapsulated, non-motile, coccobacilli with outer pili. They are generally about 0.5-1.0 µm in size. Some have reported that the bacteria are covered with surface slime or biofilm composed of carbohydrates.

- Up to 91% of patients with heart disease have periodontitis, compared to 66% of people with no heart disease. The two conditions have several risk factors in common, such as smoking, unhealthy diet, and excess weight. And some suspect that periodontitis has a direct role in raising the risk for heart disease as well.

- Infections of the Teeth, Gingivae, Periodontal Ligament and Alveolar Bone of the Jaw (Dental Caries and Periodontal Disease) Dental caries/periodontal disease usually are not diagnosed and treated by physicians; however, poor oral hygiene can result in infections that are of concern to physicians. Infections of the teeth, gingivae, periodontal ligament and alveolar bone can spread to contiguous structures (e.g., sinusitis, osteomyelitis of the jaw, aspiration pneumonia). Poor oral hygiene also contributes to cardiovascular disease.

- Chapter 3: Diseases and Disorders. As the gateway to the body, the mouth is challenged by a constant barrage of invaders—bacteria, viruses, parasites, fungi. Thus infectious diseases, notably dental caries and periodontal diseases, predominate among the ills that can compromise oral health. Injuries take their toll as well, with the face and head particularly vulnerable to sports injuries, motor vehicle crashes, violence, and abuse.

- Periodontal diseases are mainly the results of infections and inflammation of the gums and bone that surround and support the teeth. In its early stage, called gingivitis, the gums can become swollen and red, and they may bleed.eriodontal disease and tooth decay are the two biggest threats to dental health. A recent CDC report 1 provides the following data related to prevalence of periodontitis in the U.S.: 1  47.2% of adults aged 30 years and older have some form of periodontal disease.

Chronic periodontitis Sub-antimicrobial doses of doxycycline (SDD) have been used to alter host response to the periodontal pathogens. This is believed to disrupt the action of matrix metalloproteinases and thus minimise host mediated tissue destruction.

Oral microbiology Of particular interest is the role of oral microorganisms in the two major dental diseases: dental caries and periodontal disease. Fusospirochetes. Spirochetes and fusiform bacilli live as normal flora in the mouth, but in the case of bleeding in the oral cavity, the bacteria can cause infection and diseases to oral cavity: Acute necrotizing ulcerative gingivitis

Hand, foot and mouth disease Infectious agent of hand, foot and mouth disease. The major agents causing hand, foot and mouth disease (HFMD) are the human enteroviruses species A, particularly coxsackievirus A16 (CA16) and enterovirus 71 (EV71). These belong to the genus Enterovirus within the family Picornaviridae.

Gingivitis and Periodontal Disease (Gum Disease) A. A. A. Periodontitis, also generally called gum disease or periodontal disease, begins with bacterial growth in your mouth and may end -- if not properly treated -- with tooth loss due to destruction of the tissue that surrounds your teeth.laque is the primary cause of gum disease. However, other factors can contribute to periodontal disease. These include: 1  Hormonal changes, such as those occurring during pregnancy, puberty, menopause, and monthly menstruation, make gums more sensitive, which makes it easier for gingivitis to develop.

- Abstract. Background and Purpose— Chronic infectious diseases may increase the risk of stroke. We investigated whether periodontal disease, including periodontitis and gingivitis, is a risk factor for cerebral ischemia.n conclusion, our study indicates that periodontal disease is significantly associated with cerebral ischemia. Gingivitis and periodontitis are treatable and preventable conditions. Therefore, their identification as stroke risk factors that require further studies would have a major impact on stroke prevention.

periodontal disease Periodontal diseases are a group of diseases that affect the tissues that support and anchor the teeth. Left untreated, periodontal disease results in the destruction of the gums, alveolar bone (the part of the jaws where the teeth arise), and the outer layer of the tooth root.n acute infection of the periodontal tissue may occur, but is not usually reported to the dentist. The tissues that are involved in periodontal diseases are the gums, which include the gingiva, periodontal ligament, cementum, and alveolar bone.

These include: 1  Hormonal changes, such as those occurring during pregnancy, puberty, menopause, and monthly menstruation, make gums more sensitive, which makes it easier for gingivitis to develop. Illnesses may affect the condition of your gums. 2  This includes diseases such as cancer or HIV that interfere with the immune system. 3  Because diabetes affects the body's ability to use blood sugar, patients with this disease are at higher risk of developing infections, including periodontal disease and cavities.

Gum Disease and Overall Health Gum/periodontal infections can have a devastating affect on the immune system. The type of infection that is found in moderate to advanced gum disease not only involves numerous and very toxic bacteria but these organisms have constant and direct access to the blood stream and indirectly the lungs.
