Halitosis is a very frequent condition characterized by an unpleasant odor related to expired air, and 80-90% of the cases originate in the oral cavity. It is a social problem that affects one-third of the population, causing a negative impact on the quality of life. The measurement of volatile sulfur compounds (VSC) at the oral level is very useful for intercepting the problem. Photodynamic Therapy (PDT) is based on the combination of a non-toxic dye and an appropriate wavelength of visible light, which in the presence of oxygen is activated and can promote a phototoxic response. We would like to document a case of oral halitosis diagnosed and treated with photodynamic therapy using a 660 nm diode laser and phenothiazine chloride as a photosensitizer

Abstract
Halitosis is a very frequent condition characterized by an unpleasant odor related to expired air, and 80-90% of the cases originate in the oral cavity. It is a social problem that affects one-third of the population, causing a negative impact on the quality of life. The measurement of volatile sulfur compounds (VSC) at the oral level is very useful for intercepting the problem. Photodynamic Therapy (PDT) is based on the combination of a non-toxic dye and an appropriate wavelength of visible light, which in the presence of oxygen is activated and can promote a phototoxic response. We would like to document a case of oral halitosis diagnosed and treated with photodynamic therapy using a 660 nm diode laser and phenothiazine chloride as a photosensitizer
