Effect of Apical Enlargement to Different Preparation Sizes and Tapers on Pain and Bacterial Reduction in Necrotic Pulp
November 16, 2022 updated by: Nermeen AwadAllah Abbas Ibrahim, Cairo University
Effect of Apical Third Enlargement to Different Preparation Sizes and Tapers of EdgeFile X7 on Postoperative Pain and Intra-canal Bacterial Reduction in Patients With Necrotic Pulp: A Randomized Clinical Trial
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.

Conditions
Detailed Description
- 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).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Post-operative pain
Time Frame: 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.
|
up to 72 hours after endodontic treatment
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Intra-canal bacterial reduction
Time Frame: Bacterial samples will be taken Immediately after root canal instrumentation.
|
Intra-canal bacterial count will be measured using a culture technique.
The resultant growth will be visually quantified by counting the number of colony forming units per millilitre (CFUs/ mL)
|
Bacterial samples will be taken Immediately after root canal instrumentation.
