Evaluation of photobiomodulation in the reduction of pain caused by the injection of local anesthetic. Randomized, controlled, blinded clinical study

Abstract

Objectives: Evaluate the use of FBM in pain associated with the injection of a local anesthetic prior to a dental procedure.

Methodology: A randomized, patient-blinded, controlled clinical trial will be conducted. 128 participants attending the ICU who meet the inclusion criteria will participate. They will be divided by age (children aged 6 to 12 years, and adults aged 25 to 60 years) and each into two groups (laser and sham). Prior to the puncture, light or sham will be applied, depending on the group. The equipment will be Therapy EC, DMC Brasil. For the intervention group, continuous laser will be applied in direct contact with 9J of energy with wavelengths of 660nm and 808nm and 100mW of power for 45 minutes. In the simulation group, light emission will be canceled. Pain will be assessed using the Facial Image Scale (FIS) and VAS, FLACC during the injection, and physiological parameters such as blood pressure (BP), oximetry (O), and heart rate (HR) will be measured.

Expected Results: That FBM reduces the pain associated with local anesthetic puncture in both children and adults.
