摘要

Background

Prolonged soft-tissue anesthesia in children after dental procedures may cause self-inflicted injuries and discomfort. Photobiomodulation therapy (PBM) offers a potential nonpharmacological solution for accelerating anesthesia reversal.

Objective

To systematically assess PBM’s efficacy in reversing soft tissue anesthesia and preventing complications in pediatric dental patients.

Methods

A systematic search of PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials, up to October 2024, identified randomized controlled trials (RCTs) evaluating PBM in children aged 4–10. Risk of bias was assessed using The Revised Cochrane Risk of Bias Tool for Randomized Trials (RoB 2). Random-effects meta-analyses were conducted for anesthesia duration and soft tissue trauma.

Results

Five RCTs (212 patients) were included. PBM significantly reduced anesthesia duration (Mean Difference = -44.85 min; 95% CI: -83.71 to -5.99; p = 0.03), with 660 nm wavelength being most effective (-69.00 min; 95% CI: -81.68 to -56.32). Soft tissue trauma risk was lower with PBM (RR = 0.36; 95% CI: 0.07–1.78), though not statistically significant. High heterogeneity was noted (I²=94%).

Conclusion

PBM accelerates anesthesia reversal in pediatric dental patients, with 660 nm showing the greatest reduction in anesthesia duration. Standardized protocols are needed for clinical guidelines.
