简要总结
The aim of this prospective randomized clinical trial is to evaluate the effect of different apical size and taper preparation (35. 04; 35. 06; 45. 04 and 45. 06) on postoperative pain at 6, 12, 24, 48 and 72 hours, and intra-canal bacterial count in patients having mandibular premolars with necrotic pulps.
详细描述
- Patients will be clinically and radiographically examined and their eligibility will be assessed. Eligible patients will be treated in one visit.
- Patients will be randomly assigned to one of 4 groups: experimental groups of root canal instrumentation with EdgeFile X7 to size #35/0.06 or #45/0.04 or #45/0.06 or the comparator group to size #35/0.04. Intra-canal bacterial count will be measured using a culture technique. Bacterial samples will be taken before and after root canal instrumentation. After endodontic treatment, patients will be given postoperative instructions and informed, in case of pain, to receive ibuprofen 400 mg as rescue medication.
- Postendodontic pain intensity and incidence at the different pain categories (No, mild, moderate, severe) will be assessed at 6, 12, 24, 48 and 72 hours postoperatively using Numerical Rating Scale (NRS).

结局指标
主要结局
Post-operative pain
时间窗: up to 72 hours after endodontic treatment
Postendodontic pain will be measured using Numerical Rating Scale. The Numerical Rating Scale consists of a 0-10 scale, with (0) meaning "no pain" and (10) meaning "the worst pain imaginable". No or mild pain response will be considered success.
次要结局
- Intra-canal bacterial reduction(Bacterial samples will be taken Immediately after root canal instrumentation.)
