A combination of intra- and extraoral treatment was performed as mouth opening was restrictive due to trismus (Fig. 2). Symptomatic relief was noticed during the session and faster healing was observed by the patient (Fig. 3). Many ulcers showed complete healing prior to the next round of chemotherapy (Fig. 4). PBM therapy continued until the cessation of chemotherapy. Case Report 3 A 61-year old male presented to our clinic with a large cheek ulcer despite self-administering home LED photobiomodulation. e patient was undergoing radiotherapy for tonsillar cancer and required daily opioids for pain management. 1064 nm Nd:YAG laser PBM therapy was administered 3x weekly as an adjunct to his home therapy. e patient found immediate relief from the therapy and healed rapidly (Fig. 5). Furthermore, the patient was concurrently dealing with radiation dermatitis on his neck, which had nearly fully healed within 12 days following a 70 Gy radiation treatment administered over a span of 7 weeks. Typically, radiation dermatitis reaches its peak around two weeks after the completion of radiotherapy (Fig. 6). Case Report 4 A 71-year old male presented to our clinic with painful ulceration of his tongue and cheek. ese lesions appeared toward the end of his radiotherapy despite home photobiomodulation with LEDs. Both intraoral and extraoral 1064 nm Nd:YAG laser PBM therapy was performed 3x weekly (Fig. 7) and provided immediate relief. erapy continued until the lesions resolved. In conclusion, LED and laser photobiomodulation can provide prophylactic and therapeutic relief for the complications of cancer therapy. ey can be used as a monotherapy or in combination to modulate pain, accelerate healing and reduce in ammation using complementary wavelengths. As international guidelines endorse the use of photobiomodulation therapy and lasers become more readily accessible in dental clinics and hospitals, an increasing number of people with cancer can hope to avoid the debilitating complications associated with cancer treatments. u For the full list of references, contact Australasian Dentist on: gapmagazines@gmail.com
