A new study in Israel sheds light on promising developments in the treatment of burning mouth syndrome (BMS) through the application of photobiomodulation (PBM), commonly known as low-level laser therapy (LLLT). 

The work by a team at the Hebrew University-Hadassah School of Dental Medicine, is published in Oral Diseases.

The 10-week study, conducted with 30 BMS patients, not only underscores the immediate relief offered by PBM but also delves into nuanced aspects of its effectiveness.

BMS presents a complex and debilitating challenge, characterised by persistent intraoral burning or abnormal sensations, occurring without clinically-evident causative lesions upon examination and investigation. This enigmatic disorder primarily impacts the oral cavity, resulting in discomfort and pain, significantly affecting the quality of life for those affected.

The study focused on investigating how PBM influences individuals with BMS. Utilising special lights to stimulate cell function, the 30 BMS patients received intraoral treatment for 10 weeks. Pain assessments were conducted using the visual analog scale (VAS) immediately after each treatment, with a calculation of weekly average VAS aiming to evaluate both the immediate and long-term effects of PBM on alleviating BMS symptoms.

Results from the study revealed a substantial decrease in the initial pain score, as measured by the VAS, from 7.80 to 2.07 after the treatments. Although there was a slight increase in the average pain score to 5.73 in the week following the last treatment, it remained significantly lower than the initial score.

Notably, the researchers observed a trend of continued improvement in pain relief with additional treatments, particularly up to the third session. Moreover, the study highlighted that PBM demonstrated enhanced efficacy for male patients or those experiencing pain on only one side of their mouth.

PBM emerges as a promising avenue for providing immediate pain relief to BMS patients. While the efficacy diminishes in the week following treatment, the study underscores a notable trend of increased pain relief with repeated sessions, especially up to the third treatment.
