The auriculotherapy with laser biophotomodulation is a technique used to promote the body's balance and treat several conditions. Individuals with Temporomandibular Disorder (TMD) often have compromised general health. The impact of this therapy on the health of these patients is not yet fully understood.

Evaluating the effects of auriculotherapy with LASER biophotomodulation on the general health of individuals with TMD.

A randomized crossover clinical trial was conducted with 25 participants, divided into a Placebo Group (PG, n = 14) and an Experimental Group (EG, n = 11). The groups were assessed using the Patient Health Questionnaire (PHQ) before and after the intervention. The EG received treatment with LASER (100 mW, 602 nm, 5 J/cm²), twice a week for four weeks, while the PG received treatment with the device turned off. After 15 days, the groups were crossed over. Independent t-tests and paired t-tests were performed for statistical analysis.

The PHQ of the EG significantly decreased after the intervention [t(21) = 2.79, p = 0.01], while in the PG it remained unchanged [t(24) = 1.24, p = 0.20]. The comparison between groups after the intervention showed no significant difference [t(47) = 2.00, p = 0.05].

Auriculotherapy with laser biophotomodulation showed positive effects on the general health of participants in the EG, but it was not significantly superior to the placebo treatment. Implications: These results suggest that the technique may have benefits for individuals with TMD, but further studies are needed to validate its clinical efficacy.
