Periodontal treatment (PT) was associated with a decrease in these exacerbations. Bronchiectasis is a pulmonary disease that has many similarities to COPD; however, there are no studies correlating this condition to PD thus far. This study will evaluate if PT reduces proinflammatory cytokines in serum and saliva, as well as halitosis and the amount of microorganisms associated with exacerbation of bronchiectasis in saliva, sputum and nasal lavage 3\u2005months after PT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>\n                      A total of 182 patients with PD and bronchiectasis will be randomly allocated to group 1 (positive control; scaling and root planing (SRP)+oral hygiene (OH)) or group 2 (experimental; SRP+photodynamic therapy+OH). After 3\u2005months, samples of saliva, nasal lavage and sputum will be collected to determine the level of\n                      <jats:italic>Pseudomonas aeruginosa<\/jats:italic>\n                      ,\n                      <jats:italic>Staphylococcus aureus<\/jats:italic>\n                      and\n                      <jats:italic>Porphyromonas gingivalis<\/jats:italic>\n                      by quantitative PCR.
