This study was a double-blind study in which the patient, the surgeon, and the statistician were all unaware of whether the patient received treatment or a placebo control light . Only the operator using the LED light was aware of this information. The assigned group was recorded on sealed and opaque envelopes. These cards were prepared by an independent person who was not involved in the study protocol. Once the patient underwent extraction and agreed to participate in this trial, this independent person opened the envelope to reveal the allocation.
