In-office laser therapy (all types combined) vs Placebo (placebo laser or placebo agent) or no treatment

Changes in intensity of pain (VAS 0 to 10) tested through tactile stimuli · Patients aged above 12 years with self-reported tooth hypersensitivity confirmed on clinical evaluation

It is very uncertain whether in-office laser therapy (all types combined) changes changes in intensity of pain (VAS 0 to 10) tested through tactile… compared with placebo (placebo laser or placebo agent) or no treatment (very low certainty).
