Brief 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

Study Arms (3)

G1-control group

PLACEBO COMPARATOR

Arm description: G1 - control group - (n = 30) dental hygiene orientation (DHO) + supragingival treatment + simulation of using photodynamic therapy (PDT). In G1, all participants will receive supragingival treatments by an experienced specialist with universal curettes and ultrasound. Supragingival treatment will be performed above the gingival margin. The simulation of using photodynamic therapy (PDT) will be performed with laser turned off. No antibiotics and oral antiseptics will be prescribed.

Procedure: supragingival treatmentOther: dental hygiene orientation

G2- positive control group

ACTIVE COMPARATOR

Arm description: G2 - positive control group (gold standard) - (n = 30) - DHO + periodontal treatment + simulation of using PDT. All participants will receive periodontal treatment - scaling and root planning (SRP) by an experienced specialist with universal curetes and ultrasound in a full mouth manner. The simulation of using photodynamic therapy (PDT) will be performed with laser turned off. No antibiotics and oral antiseptics will be prescribed

Procedure: periodontal treatmentOther: dental hygiene orientation

G3 -experimental active comparator group

ACTIVE COMPARATOR

Arm description: G3 - experimental group - (n = 30) DHO +SRP + PDT with methylene blue In G3, periodontal treatment and photodynamic therapy (PDT) will be performed. The scaling and root planing will be performed identical as G2. The PDT will be administered in periodontal pockets \> 4mm. Methylene blue will be applied in the deep of periodontal pockets. After 5 minutes of application the red laser diode (λ = 660 nm) will be applied with output power of 100 mW with 90 seconds of exposure, i.e. 9J in each point. Applications will be held in six sites around the tooth in all teeth. To finalize, 1 minute of irradiation in scan around each tooth and rinsing with saline solution to remove the photosensitizer

Interventions

In G1, all participants will receive supragingival treatments by an experienced specialist with universal curettes (Hu-Friedy) and ultrasound (Ultra Sound Dabi Atlante - Profi Neo US, Ribeirao Preto, Brazil). Supragingival treatment will be performed above the gingival margin.

G1-control group

All participants receive periodontal treatments by an experienced specialist with universal curettes (Hu-Friedy) and ultrasound (Ultra Sound Dabi Atlante - Profi Neo US, Ribeirao Preto, Brazil) in a full mouth manner.

G2- positive control group

In G3, the periodontal treatment will be performed identical as G2. PDT will be administered in periodontal pockets \> 4mm. Methylene blue will be applied in the deep of periodontal pockets. After 5 minutes of application the red laser diode (λ = 660 nm) will be applied with output power of 100 mW (Therapy XT, DMC, São Carlos, Brazil) with 90 seconds of exposure, i.e. 9J in each point. Applications will be held in six sites around the tooth in all teeth. To finalize, 1 minute of irradiation in scan around each tooth and rinsing with saline solution to remove the FS.
