Assessment of photobiomodulation therapy by an 8l0-nm diode laser on the reversal of soft tissue local anesthesia in pediatric dentistry: a preliminary randomized clinical trial

Did you know that laser therapy can reduce soft tissue anesthesia duration in children?

About the Study:
This clinical trial, published in 2020 by our center, investigated the effect of photobiomodulation (laser therapy) on reducing the duration of local anesthesia in pediatric dentistry.

Research Method:

• Participants: 34 children aged 4 to 8 years requiring bilateral mandibular local anesthesia.
• Design: A split-mouth approach was used: one side of the jaw received treatment with an 810-nm laser, while the opposite side served as the control (no laser activation).
• Assessment: Anesthesia duration was evaluated using a touch-response technique every 15 minutes.

Results:

• Laser Group: Average anesthesia duration: 145.15 minutes.
• Control Group: Average anesthesia duration: 188.82 minutes.
• Statistical Significance: The difference between the two groups was significant (P < 0.001).

Conclusion:
Photobiomodulation with an 810-nm diode laser can be considered a non-invasive method to reduce anesthesia duration in children. This approach not only enhances patient comfort but also helps create a more pleasant dental experience for pediatric patients.
