Introduction: The management of patients with chronic burning mouth is a challenge in clinical dentistry. Objective: To compare the effect of Low Level Laser Therapy (LLLT) and Transcutaneous Electrical Nerve Stimulation (TENS) in the treatment of burning mouth. Materials and Methods: Randomized clinical trial consisting of 25 patients with burning mouth who were treated by TENS (n=12) and by LLLT (n=13). Treatment was carried out weekly for 8 weeks. Two-way ANOVA was used to verify whether there was a significant difference between times T0 (baseline), T1 (after the 4th treatment session), T2 (after the 8th treatment session) and T3 (30 days after the end of treatment) in in relation to symptoms, analyzed using the Visual Analog Scale, unstimulated salivary flow, xerostomia and dysgeusia with TENS and LLLT interventions.
Experimental group: 20 participants with burning mouth were submitted to transcutaneous electrical nerve stimulation using a device at a frequency of 50 Hertz with intensity modulated according to the patient's comfort ranging from 1 - 4 (pulse amplitude) with a duration of 25 minutes per session, with one session per week, totaling eight weeks of treatment at the end of the study. The device's self-adhesive electrodes were fixed on the participant's face, following the path of the trigeminal nerve branch on the side affected by pain and/or burning. Control group: 20 participants with burning mouth underwent low power laser therapy with punctual applications of infrared laser (L2) (power of 100mW, 808 nm, 6 joules of energy/60 seconds) in the affected region, keeping one centimeter of distance between the points, until the entire area of the complaint was irradiated. being held one session per week, totaling eight weeks of treatment at the end of the study.

Painful Symptoms
Changes in the intensity of pain/burning was determined by Visual Analogue Scale. Possible scores range from 0 (no pain) to 10 (worst possible pain).
Time frame: Baseline (T0), after the 4th treatment session (4 weeks), after the 8th treatment session (8 weeks). ), 30 days after the end of treatment (8 weeks + 30 days).
Salivary Flow
The unstimulated salivary flow rate will be determined by the ratio volume of saliva collected, expressed in millimeters per minute (ml/min).
Time frame: Baseline (T0), after the 4th treatment session (4 weeks), after the 8th treatment session (8 weeks). ), 30 days after the end of treatment (8 weeks + 30 days
