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

Description

Halitosis is an unpleasant odor that emanating from the mouth. A recent metanalysis shows worldwide trend towards a rise in halitosis prevalence. Studies show halitosis returns in a week after treatment with photodynamic therapy (PDT). Probably, bacteria residing in the periodontal sulcus could recolonize the dorsum of the tongue. To date, there are no study in adult population that associate halitosis and periodontal treatment with follow-up evaluation. 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 (n=40) with halitosis 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). 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. The evaluation of halitosis and the microbiological analysis will be repeated. After that, patients will receive periodontal treatment. The participants will return after 1 week and three months for an additional evaluation. Quality of life will be measured by Oral Health Impact Profile (OHIP-14) Comparisons will be made with ANOVA test, with the level of significance of 5 %. This protocol will determine the effectiveness of phototherapy regarding the reduction of halitosis in adults.

A simple method to reduce halitosis; tongue scraping with probiotics.

We aimed to assess the effects of probiotic implantation to the dorsum of the tongue against halitosis.

A new technique for tongue brushing and halitosis reduction: the X technique.

The tongue is one of the primary sources of halitosis. The manual or mechanical removal of biofilm is known to decrease oral malodor.

Untargeted metabolomics of the bacterial tongue coating of intra-oral halitosis patients.

Intra-oral halitosis (IOH) refers to an unpleasant odour from the oral cavity that is mainly caused by the tongue coating. Although the tongue coating microbiome is thought to play an essential role i...

Medical and Biotech [MESH] Definitions

The purified component of HEMATOPORPHYRIN DERIVATIVE, it consists of a mixture of oligomeric porphyrins. It is used in photodynamic therapy (HEMATOPORPHYRIN PHOTORADIATION); to treat malignant lesions with visible light and experimentally as an antiviral agent. It is the first drug to be approved in the use of PHOTODYNAMIC THERAPY in the United States.

A severe congenital restriction of TONGUE movement, resulting from fusion or adherence of the tongue to the floor of the mouth. In partial ankyloglossia (tongue-tie) the LINGUAL FRENUM is abnormally short, or is attached too close to the tip of the tongue. OMIM: 106280

A complex mixture of monomeric and aggregated porphyrins used in the photodynamic therapy of tumors (HEMATOPORPHYRIN PHOTORADIATION). A purified component of this mixture is known as DIHEMATOPORPHYRIN ETHER.

A benign condition of the tongue characterized by hypertrophy of the filiform papillae that give the dorsum of the tongue a furry appearance. The color of the elongated papillae varies from yellowish white to brown or black, depending upon staining by substances such as tobacco, food, or drugs. (Dorland, 27th ed)

The occurrence of of breaks or slits in the tissue of the dorsal surface of the TONGUE.
