RESUMO

Patients submitted to chemotherapy and/or head and neck radiotherapy are usually affected by oral complications, especially oral mucositis and severe pain, which demands support therapy. Although the management of such oral complications by phototherapy with LASER (Laser Phototherapy - LPT) and with LEDs has been studied, the comparison between these therapies has not been studied yet. Thus, the aim of this study is to compare the effect of these two therapies against chemotherapy-induced oral mucositis (CIOM) and pain. Forty patients with CIOM were submitted to phototherapy according to 2 groups: G1, red low power LASER; G2, red LED. The treatment was done during 10 days. The LPT was done using an InGaAlP LASER (660nm/40mW/6Jcm-²/0,24J per point). The LED phototherapy was done using 0,24J per point/80mW/630nm. CIOM grade was assessed at each session in accordance to the World Health Organization (WHO). The patient self-assessed pain was measured by means of the visual analogue scale (VAS). The results showed that both treatments were effective, however, patients with initial mucositis grade 3, submitted to LED phototherapy presented significant decrease in the mean CIOM grades when compared with patients submitted to LASER phototherapy. In addition, LED showed better results in pain relief of patients with initial mucositis grade 1 and 2 (p=0,012 e 0,022, respectively) when compared with LASER therapy. In conclusion, phototherapy with LED is more effective than LPT on the management of CIOM which in turn would improve the patients quality of life.
