Treatment Using Low Level Laser Therapy in The Oral Manifestations of Steven Johnson Syndrome

This paper reports the objective intervention of the Hospital Dentistry team of the Beneficent Association of Campo Grande Santa Casa, contemplating a multi-professional approach to present Low-Level Laser Therapy (LLLT) as a therapeutic alternative for the treatment of individuals with Stevens-Johnson Syndrome (SJS). Male patient, 13 years old, with an initial complaint of pain, edema and burning mouth was treated by in situ applications of LLLT - Aluminium Gallium Indium Phosphide - InGaAlP type diode Laser (Laser duo / DMC Therapy XT, São Carlos, SP, Brazil), to promote photobiomodulation and subsequent repair of the compromised mucosa. Monitoring the patient during four laser therapy sessions with 24-hour intervals between them revealed a favorable evolution of the clinical picture with tissue repair, decreased pain and consequent oropharyngeal homeostasis. The favorable results consolidate LLLT as an alternative to be adopted with considerable effectiveness in combating pain and tissue changes in the oral mucosa resulting from the SJS.

A nanoscale molybdenum disulfide (MoS2) film functions both as an effective protection layer and excellent hydrogen evolution catalyst for GaInP2 photocathodes.
