    Abstract

    Burning Mouth Syndrome (BMS) is an intraoral chronic burning or dysesthetic sensation, without clinically evident causative lesions on clinical examination and investigation. Aim: To assess immediate and weekly effects of photobiomodulation (PBM) on BMS patients. Methods: Thirty BMS patients were treated intra-orally with photobiomodulation 940(±10) nm (InGaAsP) 3 W, semi-conductor diode, weekly, for up to 10 weeks. Pain intensity, measured using the Visual Analogue Scale (VAS), and characteristics were recorded immidiately after each treatment, along with a weekly average VAS. Results: Immediate mean VAS score decreased from a starting score of 7.80 ± 1.83 to 2.07 ± 2.55 (p < 0.001). The mean weekly VAS score for the week after the final treatment session was higher (5.73 ± 2.80, p < 0.001) than the immediate response, but still significantly lower than the starting score (p = 0.017). We observed a trend of pain improvement with more treatments, but this was only statistically significant up to the third treatment. Male gender and unilateral pain correlated with better PBM efficacy (p = 0.017, 0.022, respectively). Conclusion: PBM provides significant immediate pain relief for BMS patients after each treatment; however, the efficacy decreases notably over the following week. A trend of increasing pain relief across treatments was observed, statistically significant up to the third treatment.
