Maximum pain (verbal rating scale, VRS) · People requiring retreatment of periapical lesions (failed root canal therapy)
It is very uncertain whether low energy level laser therapy (LLLT) changes maximum pain (verbal rating scale, VRS) compared with control (no laser device used) (very low certainty).
