The purpose of this study is to determine whether enlarging the apical foramen causes postoperative pain in teeth with necrotic pulp and apical periodontitis.
Foraminal enlargement (FE) is an intentional procedure that enlarges the cement canal. However, some RCTs indicate that enlarging the FE causes postoperative pain, flare-up, and destroy the apical constriction, whilst some RCTs pointed out there is no difference in terms of pain when a FE has been performed. The investigators, therefore, would like to conduct a RCT to increase both sample size and the number of published studies to do a systematic review for this topic.

After determining the working length, a flexible size 30 K-file will be inserted 1 mm beyond the WL and the apical foramen will be enlarged.
4-step pain intensity measures using a Visual Analog Scale (VAS).
The severity of pain in 1-7 days according to the VAS: 0-3 mild pain, 4-7 moderate pain, and 8-10 severe pain.
Time frame: 7 days.
The number of patients taking an analgesic following the endodontics treatment.
The patients were asked to take an analgesic in the 7 days of time frame.
Time frame: 7 days.
