Evaluation of Periodontal Treatment in Patients With Bronchiectasis

Brazil30 participantsStarted 2016-08

Plain-language summary

Background: Association between periodontal disease (PD) and chronic obstructive pulmonary disease (COPD) has been widely studied and the aspiration of periodontal pathogens is one of the most accepted causal mechanisms for pulmonary exacerbation. Bronchiectasis is clinically quite similar with COPD, including chronic administration of antibiotics, increased systemic inflammation and relatively similar clinical symptoms, but for the time being; there are no studies that have correlated this condition to PD. This study will evaluate if the scaling and root planning (SRP) associated with photodynamic therapy improves periodontal clinical parameters, halitosis, and the quantity of microorganisms associated with exacerbation of bronchiectasis in saliva, subgingival periodontal microenvironment, sputum and nasal lavage at baseline, after 3 months and one year of SRP. Methods/Design: Ninety patients with chronic periodontal disease and bronchiectasis will be enrolled in the study and they will be treated as follow:G1 control (n = 30) - supragingival scaling (SS) and dental hygiene orientation (DHO); G2 experimental (n = 30) - SRP + DHO; G3- experimental (n = 30) - SRP + PDT + DHO. The quantification of bacterial groups commonly associated with exacerbation of bronchiectasis (P aeruginosa, S. aureus) and periodontal diseases (P. gingivalis), will be evaluated in periodontal pockets, saliva, nasal lavage and sputum by quantitative PCR at baseline 3 months and one year after the SRP. G1 patients will receive SRP upon completion of the investigation. If the mean depth of probing of this group worsen (\> 1mm) at 3 months they will be excluded from the study, treated (SRP) and the data will be described. Discussion: The results of this protocol will determine the efficacy of periodontal treatment in decreasing the total amount microorganisms in saliva periodontal pocket, sputum and nasal lavage, the most probable niches of bronchiectasis exacerbation, and reducing local inflammation and halitosis after 3 months and one year. It is expected an higher improvement in all parameters measured over 3 months and 1 year for G3

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients must have \> 35 years, both genders, \> 10 teeth with chronic moderate generalized periodontal disease , i.e. more than 30% of teeth examined with ≥ 4 mm probing depth. Exclusion Criteria: * Exclusion criteria include smokers or former smokers for less than five years, pregnant, people with cystic fibrosis and asthma, phenytoin or cyclosporine users (because they affect periodontal status), decompensated systemic diseases requiring prophylactic antibiotic therapy for periodontal treatment, who used oral antiseptics or anti-inflammatory in the last 3 months, or periodontal treatment performed in the last 6 months.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
