IRCT20220607055098N1 IRCT 2022-08-16 Islamic Azad University Effect of root canal disinfection by 980nm Diode laser on post operative pain after single visit root canal treatment of first and second maxillary molars Effect of root canal disinfection by 980nm Diode laser on post operative pain after single visit root canal treatment of first and second maxillary molars: A randomized clinical trial 2022-09-06 anticipated 54 Complete https://irct.ir/trial/64253 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: The randomization method is balanced block. The randomization unit of each molar tooth belongs to each single patient and only one molar tooth from each patient is included in the study. The randomization tool uses a table of printed random numbers, the odd digit of group A and the even digit of group B until the intervention in the block is filled, and then the results are recorded in the order of registration and allocation of each sample inside the sealed envelope, which at the time of the intervention The envelope will be opened. The way to make a random sequence is based on the sequence of people's referrals. The person who determines the type of random allocation of samples is the consultant of methodology and statistics of the study, who leaves the sealed envelopes at the disposal of the clinical researcher and has no role in the clinical research process. The envelopes remain sealed until the intervention and are opened in the order mentioned on the back of the envelope, Blinding description: The steps of both groups are the same. In both the laser and placebo groups, the tips will be inserted into the canal to the working length , but in the placebo group the lasers will not be activated and only the disinfection steps by laser will be simulated. Before the operation, the two groups will be explained to the patients and all the patients will be told that you are not aware of the treatment group. N/A نکروز پالپی. Intervention 1: Intervention group: Laser : After preparation of the canal, the laser radiation will be performed by a 980 nm diode laser in the root canal. Irradiation will be performed in 4 pulses, each pulse is laser radiation for 5 seconds and then stops for 10 seconds. The movement speed of the tip is 2 mm/s and the location of the tip is 1 mm above the apex. It will be performed with a power of 1.2 watts, and the tips with a diameter of 200 microns and a length of 15 mm go into the canal until the working length, and the laser is irradiated by rotation and then exits the channel. Intervention 2: Control group: Similar to the laser group, tips will be inserted into the canal but won't be activated and the steps will be simulated. Yes - There is a plan to make this available What will be shared: All potential data can be shared after the participants are unidentifiable. When: Access period starts from 2024. To whom: Only for researchers working in academic and scientific institutions. Conditions: The data can be used for scientific researches.
