IRCT20230707058704N1 IRCT 2023-07-25 Islamic Azad University The Effect of Endoactivator on Postoperative Pain The effect of Endoactivator on Postoperative Pain in necrotic teeth with Apical Periodontities, a Clinical Trial Study 2023-09-23 anticipated 44 Complete https://irct.ir/trial/71174 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: In this study, we will use the simple randomization method of the random number table type. Since the total number of study subjects is 44 people and a two-digit number, we give each person a two-digit code. Then, to select sample people from the table, by closing the eyes and putting the tip of the pen on the table, starting from a point of the table in the direction of the row or column, and taking into account that the code of each person is two digits, we start choosing two-digit numbers. The selected number is actually the code of an individual from the community that is selected as a sample. This continues until the number of people in the inducer group sample (22 people) can be chosen smaller than 44..In order to conceal, we use concealment allocation, which is the method used to perform a random sequence on the study participants, in such a way that the assigned group is not known before the allocation of the individual. Using opaque envelopes sealed with a random sequence (envelopes opaque, sealed, numbered sequentially), in this method, each of the random sequences created is recorded on a card, and the cards are placed inside the envelopes in order They are placed.In order to maintain a random sequence, the outer surface of the envelopes is numbered in the same order. Finally, the lids of the envelopes are glued and placed in a box. At the time of registration of participants, based on the order of entry of eligible participants into the study, one of the envelopes will be opened and the assigned group of that participant will be revealed, Blinding description: After obtaining the consent form and general introduction of the study groups to the participants, the information that can cause the test result to deviate remains hidden from the participant's view, but the person responsible for conducting the test is aware of them and the study is conducted in a single blind manner. N/A necrotic teeth with apical periodontitis. Intervention 1: Intervention group: washing the canal with an induction activator, so that the tip of the device continuously injects 0.5% sodium hypochlorite into the entrance of the canal for one minute, and each washing cycle includes placing the tip during operation for 6 seconds and then placing it in It is two millimeters shorter than the working length for another 6 seconds and repeat this again for 30 seconds. Intervention 2: Control group: standard washing is done using a 5cc 30 gauge syringe with a side hole made of stainless steel, the needle goes to 3 mm working length and washing is done with 0.5% sodium hypochlorite and 17% EDTA for one minute. 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 it should be further investigated
