abstract: Oral hygiene care reduces risk of pneumonia three-fold Good oral hygiene can prevent death from pneumonia, according to a new study from the US National Institute of Dental and Craniofacial Research in Bethesda, Maryland. Pneumonia is the leading cause of death in older nursing home residents, and is often triggered by aspirating saliva or food. However, analysis of medical records of 143 older people in a nursing home showed that the help of a certified nursing assistant assigned to provide oral hygiene care reduced the risk of dying from pneumonia three-fold.
