Relationship between pneumonia and periodontal diseases

Background and Aim: Becauase respiratory infection can occur by aspiration of oropharyngeal flora into the lower respiratory tract, it has been suggested that periodontal microorganisms may act as a potential source for respiratory infection especially in patients with advanced periodontal diseases. The purpose of this study was to determine the role of periodontal diseases in the pnemonia. Method and Material: Samples of this investigation consists of 46 patients (23 cases and 23 controls). Samples were matched based on their age, gender, occupation and educational level. None of the patients had reported to have any smoking, alcohol drinking habit, or systemic disease. Results: The results indicated that 17.4% of the control group and 65.2% of the case group who had pneumonia, suffered from either moderate or severe periodontal diseases (P<0.001). This indicates chance of 3.7 times exposure to pneumonia in case of periodontal diseases. The rate of attachment loss was 0.86±0.39 mm in control group, and 1.65±0.92 mm in cases (P<0.001). The G.I moderate to severe in control group was 78.3% and in cases 95.7% (P<0.08). Conclusion: A difinite relation was seen between pneumonia and periodontal disease with higher chance being evident in cases with a type of periodontal disease.
