The last digit on the right determines the patient group. If this number is 0, 1, 2, 3, 4, it will be assigned in the first intervention group, and if this number is 5, 6, 7, 8, 9, it will be assigned in the second intervention group. N/A Necrotized primery molars. Intervention 1: In the first intervention group, the canals are prepared using children's Protiper rotary files. Children's rotary files are filed with numbers 20, 25 and 30. After complete filing, a sample is taken from the distal canal again using a paper cane number 40 and transferred to the normal saline environment. Ten dilutions are prepared from each sample and 100 microliters of each dilution is cultured in the blood agar medium. Intervention 2: In the second intervention group, we use manual files to clean the channels. In this way, first using the manual file number 15 and after determining the length of the channels from the graph, the cleaning of the channels starts with the filing movement. Then it ends with files number 20, 25 and 30, respectively, of cleaning the channels.
