Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The patients included in the trial will have their mucosal area affected by the burning sensation measured and calculated in square centimeters. This figure will be used to calculate the period of time of irradiation according to the following equation: energy (6J) X area affected (cm2) / power (0.12 Watts). Irradiation will be delivered in scanning mode twice a week, during two weeks.
Intervention code [1] 3830 0
Treatment: Other
Comparator / control treatment
The control group will be submitted to the same steps, without receiving active laser irradiation. The laser applying point will be placed in contact with the mucosa affected and the patient will hear the beep sound of the timer with no laser irradiation on.
Control group
Placebo

Outcomes
Primary outcome [1] 5206 0
To evaluate the effect of low level laser therapy on the treatment of burning mouth syndrome (BMS) patients through the use of visual analogue scales and a questionnaire on the global perceived effect of the therapy.
Timepoint [1] 5206 0
Evaluation of symptoms pre and post irradiation sessions, and 7,14,30,60 and 90 days after the last irradiation.
Secondary outcome [1] 9312 0
To investigate possible correlation between number of fungiform papillae on the tongue dorsum and the severity of symptoms. The tongue papillae will be visually counted through magnification of a photograph taken from the tongue dorsum with a plastic template of one square centimeter.
Timepoint [1] 9312 0
Prior to low laser irradiation sessions, 7 days and 90 days after the last irradiation.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be selected by two specialized researchers responsible for the correct diagnosis and for presenting the informed consent to the subjects. Randomization will be performed with the aid of a computer software by a researcher not involved with the clinical environment of the trial. Allocation concealment will be done with the use of sealed envelopes sequentially numbered which content will be known by the clinical researcher only at the time of group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (www.graphpad.com)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
