Management of the oral environment in patients with diseases of oral and maxillofacial region is very important to reduce not only the aggravation of dental caries and periodontal disease, but also local wound infections and aspiration pneumonia.　Patients who required maxillomandibular fixation for the treatment of mandibular fracture or orthognathic surgery, a stronger oral environment management is required.
