Abstract
Oral complications of cancer therapy, such as oral dryness, dysphagia, and taste alteration, are associated with a negative impact in the quality of life of the patients. Few supportive care measures are available for such complications. This case series reveals the effectiveness of the photobiomodulation (PBM) therapy when used in a specific protocol and parameters, in the management of oral complications related to cancer therapy. Dysphagia was measured using the functional outcome swallowing scale for staging oropharyngeal dysphagia (FOSS). Oral mucositis was measured according to the National Cancer Institute scale. The quantity of the whole resting and stimulated saliva was measured in order to assess the oral dryness. In addition, the taste alteration was measured according to a protocol suggested by the International Standards organization (ISO). Sensation of burning mouth was measured using a visual analogue scale. These measurements were made before treatment, during, and at the end of the treatment. Diode laser 635 nm was used in 3 J/cm2. Five sessions interleaved with 24 h breaks were conducted for the dysphagia and oral dryness, and 10 sessions were conducted for the taste alteration and burning mouth sensation. Regardless of the limitations of this case series, PBM can be considered safe, time saving, and a promising approach for the management of the oral complications due to cancer therapy and the quality of life of cancer patients.
Highlights
Photobiomodulation (PBM) therapy is a therapeutic approach that modulates biological activity by employing light at red and near-infrared wavelengths [1,2,3].The North American Association of Laser Therapy (NAALT) and the World Association of LaserTherapy (WALT) reached a consensus in 2014 on the nomenclature of photobiomodulation (PBM) as the therapeutic use of light [4,5]
Oral mucositis measurements were made according to the National Cancer Institute
During the high dose radiation therapy, the patient started to complain of a chronic oral dryness that persisted over time
Summary
Photobiomodulation (PBM) therapy (photon and biological modulation) is a therapeutic approach that modulates biological activity by employing light at red and near-infrared wavelengths [1,2,3]. Therapy (WALT) reached a consensus in 2014 on the nomenclature of photobiomodulation (PBM) as the therapeutic use of light [4,5]. The application of PBM has moved on rapidly due to the combination of a better understanding of the technical, clinical, and photobiological principles of the use of red and infrared light [7]. A great number of studies suggest that. PBM significantly reduces inflammation process, reduces pain, prevents fibrosis, and enhances wound healing and tissue regeneration [7,8]. There is a surfeit of studies evidencing that PBM
