The oral cavity has been considered as a site of colonization of respiratory pathogens.The colonization of respiratory pathogens appears to be a risk factor for lung infection in high risk subjects.The mechanism of lung infection could be due to aspiration of the pathogens into the lungs. Edentulous patient are less likely to be affected compare to dentulous patient or patient who are using dentures.Most common pulmonary disease associated with periodontitis are Chronic obstructive pulmonary disease and pneumonia.These review underline the importance of improving oral hygiene among patients who are at risk.
