In the last decades, the emergence and spread of antimicrobial resistance bacteria has been viewed. Multidrug resistant bacteria are currently considered agents of worldwide emerging diseases and thus an important public health problem. Coordinated efforts to develop new therapeutic strategies are necessary. Photodynamic therapy (PDT) is a therapeutic modality based in photochemical and photophysical processes. PDT has been shown to be effective in bacterial lysis and safe in oral cavity for oral disinfection [1,2]. We report a clinical case of recurrent pharyngotonsillitis (FT) in presence of microorganisms that did not respond to antibiotic treatment. The PDT was applied in three sessions in two steps: application of pharmaceutical formulations containing 0.75 mg/mL curcumin and illumination at 450 nm and 6.57 J/cm2. It was concluded that the PDT may be used as treatment in cases of antibiotic failure. In addition, periodically the PDT may be applied in case of recurrent pharyngitis.
