Dental cleaning is good for oral health, but it is not for everyone, especially people with systemic diseases. Tooth cleaning can bleed, so the patient with hemorrhagic disease, must choose the time of cleaning the tooth carefully, want to be able to wash a tooth after systemic disease is stable. In patients with infectious diseases such as hepatitis and tuberculosis before cleaning, should truthfully explain own condition to the medical staff and patients with acute hepatitis and tuberculosis activity, should acute infectious disease control until after the cleaning. In order to avoid cross-infection, the treatment of infectious disease patients should be treated with special treatment, which is not only responsible for the large number of non-communicable diseases, but also for the special care of patients with infectious diseases.
