IRCT20141222020396N2 IRCT 2018-06-22 Islamic Azad University The effect laser on reducing pain during injection The effect of low_level laser(810 nm),Benzocaine anesthetic gel and pressure on reducing pain during infiltration injection 2018-06-10 anticipated 16 Complete https://irct.ir/trial/28503 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Crossover, Purpose: Prevention, Randomization description: simple randomization, sequential, sealed envelop.At the first session, the patient has four sealed envelopes containing four interventions that randomly select one and the selected envelope will be deleted at next sessions(1,2,3), Blinding description: volunteers are blind because of the complete simulation of interventions(all interventions are implemented by the low probability laser probe).and the post injection pain assessor is blind because is different with the operator. N/A pain control. Intervention 1: Intervention group: diode Laser 810 nm, power 0.08 W, Dose 2 J/cm2 in 12.5seconds(Dental diode laser,navidAssayesh parsian,IRAN). Intervention 2: Intervention group: benzocaiene 20% gel for 2 minutes. Intervention 3: Intervention group: Pressure for 2 minutes while the injection area tissue is pale. Intervention 4: Control group: placebo which all the previous interventions will simulated for volunteers. Yes - There is a plan to make this available What will be shared: all the data of each volunteer can be provided after being unidentifiable. When: Starting 6 months after article publication To whom: All the volunteer can also apply to receive it. Conditions: Any requested analysis is valid. Where to obtain: Contact the person responsible for the study by email How to obtain: Information will be available within 1 month of the request Comments:
