Abstract
The association between periodontal disease (PD) and chronic obstructive pulmonary disease (COPD) has been greatly studied and aspiration of periodontopathogens is one of the most accepted causal mechanisms for pulmonary exacerbation. The periodontal treatment was associated with decrease of these exacerbations. The bronchiectasis has many clinical similarities with COPD, but so far the relationship with PD has not been studied yet. Therefore, the hypothesis to be tested is whether bronchiectasis is associated with PD, and if periodontal therapy may reflect positively in the improvement of clinical parameters of bronchiectasis. Objective-Evaluate the prevalence of PD in bronchiectasic paired with healthy patients and evaluate if periodontal therapy may result in alteration in the quantity of bronchiectasis exacerbations. Methods: This study will be divided in: phase 1 will be verified the prevalence of PD in bronchiectasic patients (n = 143) matched with healthy controls. They undergo periodontal clinical examination and will respond to three questionnaires for assessing quality of life. In stage 2, bronchiectasic patients with PD are randomly allocated into two groups: G1 control (n=20) will receive supragingival scaling (RS) and orientation for oral hygiene (OH) every 3 months; while the experimental group G2 (n=20) will receive full mouth disinfection and OH every 3 months. At baseline and after 24 months, quantity of exacerbation, clinical pulmonary data by means of anamnesis, periodontal condition by means of clinical examination and three questionnaires of quality of life will be applied. Samples of saliva, nasal lavage and sputum will be collected, and determined the level and proportion of P. aeruginosa, S. aureus and P. gingivalis will be determined by qPCR. Furthermore, the assessment of oral halitosis through Chroma®. This data will allow to evaluate whether periodontal treatment may interfere in the clinical parameters of bronchiectasis and periodontal disease. It is expected that periodontal treatment contributes to the improvement of systemic clinical condition of the patient and therefore with their quality of life. Through further in vivo studies, we will investigate the underlying mechanism of action that associates these two diseases, using the microbiological data obtained in this preliminary study. (AU)
