Brief Summary

Halitosis is the term used to define an unpleasant odor emanating from the mouth. Some lung diseases, such as bronchiectasis, are among the extra-oral causes of this condition. However, no studies have evaluated the reasons and treatment of halitosis in the population of adults with bronchiectasis. Methods and analysis: A randomized, controlled trial is proposed. Halitosis will be evaluated based on the measurement of volatile sulfur compounds (VSC) using gas chromatography. The participants (n=40) with halitosis and bronchiectasis will be randomized into two groups: G1-treatment with photodynamic therapy (n = 20) or G2-cleaning of the tongue with a tongue scraper (n = 20). After the treatments, a second evaluation will be performed, along with a microbiological analysis (qPCR) for the identification of the bacteria P. gingivalis and T. denticola. If the halitosis persists, the participants will receive periodontal treatment. The evaluation of halitosis and the microbiological analysis will be repeated. If the halitosis is solved, the participants will return after three months for an additional evaluation. This protocol will determine the effectiveness of phototherapy regarding the reduction of halitosis in healthy older adults and those with bronchiectasis.

Outcome Measures

Primary Outcomes (1)

  • halitmetry (gas chromatography test)

    The portable Oral ChromaTM will be used for the assessment of halitosis. Oral air collection will follow the manufactured guide lines (Oral Chroma Manual Instruction). A syringe will be placed in the patient's mouth with the plunger completely inserted and the participant will breathe through the nose with the mouth closed for one minute.The plunger will then be withdrawn to fill the chamber with air. The gas injection needle will be placed on the syringe and the plunger will be adjusted to 0.5 ml. This air will be injected into the input of the device in a single motion. This procedure will be done before, immediately after aPDT or scraper and after periodontal treatment.

Secondary Outcomes (1)

  • microbiological analysis

    before aPDT or scrapper , immediately after aPDT or scrapper , immediatly after periodontal treatment, 3 months later

Other Outcomes (1)

  • Oral Health Related Quality of life (OHRQoL)

    before PDT or scrapper , 3 months after the halitosis treatment

Study Arms (2)

aPDT group

ACTIVE COMPARATOR

G1- 40 patient 40 patients will be included in this group. One section of Pdt will be performed with the photosensitizer (PS). PS will be applied in sufficience quantity to cover the middle third and back of the tongue and wait for 5 minutes.six points with the distances of 1 cm between them will be irradiated. The apparatus shall be precalibrated at wavelength 660nm for 90 seconds per point.

Device: pdt experimental groupOther: tongue scraper group

experimental tongue scrapper group

EXPERIMENTAL

40 patients will be included in this group. Tongue scrapping will be performed by the same operator in all patients. Posterior -anterior movements will be performed with the scrapper over the lingual dorsum. in order to promote the mechanical removal of tongue coating

Device: pdt experimental groupOther: tongue scraper group

Interventions

G1-40 patients Photodynamic therapy with methylene blue as photosensitizer device irradiation with low intensity laser (wave length = 660 nm) 9J (Jaules) per point(6 points) and radiant 90 seconds PS will be applied in sufficient quantity to cover the middle third and back of the tongue and wait for 5 minutes.six points with the distances of 1 cm between them will be irradiated.
