Post Operative Pain
Conditions
Brief summary
This study aims to research the effect of different instrument designs by comparing protaper ultimate versus protaper gold systems on root canal preparation by evaluating bacterial count reduction and post-operative pain following single visit treatment in patients with necrotic pulp in maxillary premolar teeth.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Post Operative Pain | Postoperative pain will be measured by modified Visual Analogue Scale immediately after the end of treatment, and at 6, 12, 24 and 48 hours. | Intensity of pain felt after endodontic treatment recorded by the patient using modified Visual Analogue Scale where 0=no pain, 1-3=mild pain, 4-6=moderate pain and 7-10=severe pain |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of needed analgesic tablets in case of intolerable pain | Patient will be contacted after 48 hours after endodontic treatment to know the number of analgesic tablets taken | The patient will record the number of analgesic tablets taken in case of intolerable pain |
| Antibacterial Effectiveness | First as a Baseline (T0): After the access cavity Sample 1 will be taken, after 15 minutes (T1) mechanical instrumentation will be done and Sample 2 will be taken, after 5 minutes from T1 (T2) final irrigation will be done and Sample 3 will be taken. | Bacterial counting using agar Culture technique |
