It has been emphasized that pain reduction without analgesic drugs is necessary in orthodontic treatment. Especially, needed is reduction after the initial wire application. Soft laser irradiation has been applied in dental clinics, and we reported its effectiveness in pain reduction in orthodontic treatment. In this study, we evaluated the continuous effects of the laser irradiation by questionnaire and pulp sensitization measured by pulp electrodiagnosis. The laser irradiation time required for pain reduction was also examined. We confirmed that soft laser irradiation produced an effective pain reduction in orthodontic treatment.
