IRCT20231209060303N1 IRCT 2024-01-09 Yazd University of Medical Sciences Investigating the effect of low level diode laser on the pain caused by local anesthesia in dentistry Investigating the effect of low level diode laser on the pain caused by local anesthesia in dentistry 2024-01-10 anticipated 30 Complete https://irct.ir/trial/74631 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Education/Guidance, Randomization description: The randomization method in this experiment is simple and the randomization unit will be individual. In this way, the trained clinical assistant will determine by random number table which side of the jaw (left or right) each person will be lasered on and on which side the laser will be turned off. The patient and the dentist will not know which side of the laser. And they don't know which side of the off laser was irradiated, and only a trained assistant who is aware of random numbers will perform the irradiation and collect the information in a checklist, Blinding description: The dentist and the patient do not know which side of the laser and which side of the sham laser or silent laser is irradiated because both types of lasers have the same light and sound, and both sides of the front of the patient's upper jaw require dental procedures that require It infiltrates numbness. N/A Comparing the effect of laser with placebo in reducing pain caused by anesthetic injection. Intervention 1: Intervention group: Diode laser with a wavelength of 980 nm manufactured by Dr.smile company in Italy will be used. The cross-section of the handpiece is in the form of a circle with an area of ​​one square centimeter, which is in contact with the mucosa without putting pressure on it. The parameters of the laser include a power of 300 milliwatts (0.3 watts), an irradiation time of 20 seconds, and an energy density of 6 joules per square centimeter. Intervention 2: Control group: using a laser device; A sham laser, which has the same light, sound and appearance as a low-power diode laser, will be emitted. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is There is no further information

The VAS measure is a ten-centimeter segment numbered from 0 to 10. The number zero indicates no pain (there is no pain) and the number 10 means the most pain that the patient has experienced during his life. Timepoint: Immediately after injection of anesthesia. Method of measurement: VAS criterion. Yazd University of Medical Sciences Approved 2023-12-16 Ethics Committee of Yazd Faculty of Dentistry Yazd Dahe fajr Boulevard.
