Title: Photobiomodulation therapy in the treatment of oral mucositis, dysgeusia and oral dryness as side - effects of head and neck radiotherapy in a cancer patient: Case report
Introduction: Successful management of oral mucositis, dysgeusia and oral dryness was made with fivesessions of photobiomodulation (PBM). Methods: The severity of oral mucositis was measured according to the World Health Organization scale for the assessment of oral mucositis. Dysgeusia testing was performed according to the International Standards Organization (ISO). For the assessment of oral dryness or hyposalivation, quantity of the total resting and stimulated saliva was measured. Photobiomodulation parameters, applications, and treatment protocol used were suggested by an international multidisciplinary panel of clinicians and researchers with expertise in the area of supportive care in cancer and/or PBM clinical application and dosimetry. Results: Five sessions of PBM were made with a 24 hours between each. Oral mucositis that was 2 before treatment droped to 0 after treatment World health organization scale). Dysgeusia was back to normal: patient scored 5/5 on the ISO test. Quantity of saliva (Q-sal, mL/min) increased from respectively 0.05 and 0.11 for the resting and stimulating saliva to 0.12 and 0.27 respectively. Conclusion: This case report confirms the effectiveness of photobiomodulation therapy in the management of oral mucositis, dysgeusia, and oral dryness.
