NCT03996915

Brief Summary

The aim of this randomized, controlled clinical trial was to treat oral halitosis in healthy adults with photodynamic therapy associated with periodontal treatment and follow them up for 3 months. The participants with halitosis will be randomized into two groups: G1-treatment with photodynamic therapy or G2-cleaning of the tongue with a tongue scraper . Halitosis were evaluated measuring volatile sulfur compounds using gas chromatography After the treatments, a second evaluation will be performed, along with a microbiological analysis (qPCR) for the identification of the bacteria T. denticola

Outcome Measures

Primary Outcomes (1)

  • halitosis measurement (gas chromatography test)

    The portable Oral Chroma 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and the participant will breathe through the nose with the mouth closed for one minute.The plunger will then be withdrawn to fill the chamber with air. This procedure will be repeated. 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 PDT or scraper and after periodontal treatment.

    through study completion on average of one year

Secondary Outcomes (1)

  • microbiological analysis

    through study completion on average of one year

Study Arms (2)

experimental PDT group

EXPERIMENTAL

G1-20 patients Photodynamic therapy with methylene blue as photosensitizer device irradiation with low intensity laser (wave length = 660 nm) 9 J (Joules) per point (6 points) and radiant 90 seconds. Photosensitiser (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.

Device: Pdt Photodynamic Therapy

control tongue scrapper group

ACTIVE COMPARATOR

G2-20 patients 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

Other: tongue scrapper
