What is Antimicrobial photodynamic therapy with Bixa orellana extract and blue LED in the reduction of halitosis—A randomized, controlled clinical trial about?

## Background: This study aimed to evaluate the reduction of halitosis when using antimicrobial photodynamic therapy (apdt) with bixa orellana extract and blue light-emitting diode (led). ## Methods: Forty-four uninove students or employees with a diagnosis of sulfide (h2s) ≥ 112 ppb in gas chromatography were selected. the patients were randomly divided in groups: group 1 (n = 15): apdt with annatto and led; group 2 (n = 14): tongue scraping; group 3 (n = 15): tongue scraping and apdt. for apdt, a wasbixa orellana extract used in a concentration of 20 % w/v (fórmula e ação®, são paulo, brazil) on the tongue for 2 min, associated with a blue-violet led (valo cordless ultradent® products, inc., south jordan, ut, usa) (395-480 nm). six points were irradiated on the back of the tongue, at wavelength 395-480 nm for 20 s, energy of 9.6 j and radiant energy of 6.37 j/cm per point. the results were compared before, immediately after treatment and 7 days after. the friedman test was used for the intragroup analysis and the kruskal wallis test for the intergroup analysis. ## Results: In all groups, there was a difference between baseline and the value immediately after the treatment. in gro
