摘要

Aim

To evaluate the effect of low-level laser therapy (LLLT) on pain perception during dental procedures in children.

Objective

To assess the effectiveness of LLLT in reducing pain perception compared with traditional interventions during various dental procedures in children.

Methods

A systematic review of the literature from 2000 was conducted, adhering to PRISMA guidelines. Multiple databases were searched. Six randomized controlled trials (RCTs) were included. Data extraction was performed independently by two reviewers.

Results

Six RCTs met the inclusion criteria. LLLT was found to be beneficial in controlling pain during certain dental procedures. Most children preferred LLLT over placebo or topical anesthetic gel.

Conclusion

Diode LLLT significantly reduced pain compared to placebo in children. It appears that C fibers are more affected by LLLT than A-delta fibers in pain reduction during different dental procedures.
