Abstract
Objective: This study aims to review the literature on the relationship between periodontal disease and its influence on respiratory disease. Methods: Through literature review we searched and selected published scientific articles related to periodontal disease and its involvement with respiratory disease. Development: Periodontal disease occurs mostly in patients whose oral health is not treated. That is, when there is no preventive control over the microbiota present in the oral cavity, thus allowing the entry of pathogens and beginning of pathological process. Respiratory diseases are as frequent as any other disease. Because they are very common, individuals do not give the proper value and worsen their state of health, because they are correlated to bad habits, climate or extrinsic factors such as viruses and bacteria. It is important to approach these two areas of health to a good knowledge among their correlation in the body. The onset of a respiratory disease is directly related to the rate of colonization of respiratory pathogens in the oral cavity and oropharynx due to its aspiration through the lower airways leading the organism to a state of defense mechanism of the host. Final considerations: Prevention by previous dental treatment is necessary to avoid any future grievances regarding the patient's systemic health in case of respiratory disease and its involvement with periodontal disease. Therefore, further studies on their associations are important for better improvement on the subject.
