-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| pre-operative pain before single visit root canal treatment by NRS (numerical rating scale) | Primary outcome will be assessed by NRS (numerical rating scale), the unit of measurement is categorical.The scale is from (0-10) (1-3) Mild pain (4-6) Moderate pain (7-10) Severe pain | Baseline | 
| post-operative pain after single visit root canal treatment by NRS (numerical rating scale) | Primary outcome will be assessed by NRS (numerical rating scale), the unit of measurement is categorical.The scale is from (0-10) (1-3) Mild pain (4-6) Moderate pain (7-10) Severe pain | after treatment by 6 hours | 
| post-operative pain after single visit root canal treatment by NRS (numerical rating scale) | Primary outcome will be assessed by NRS (numerical rating scale), the unit of measurement is categorical.The scale is from (0-10) (1-3) Mild pain (4-6) Moderate pain (7-10) Severe pain | after treatment by 12 hours | 
| post-operative pain after single visit root canal treatment by NRS (numerical rating scale) | Primary outcome will be assessed by NRS (numerical rating scale), the unit of measurement is categorical.The scale is from (0-10) (1-3) Mild pain (4-6) Moderate pain (7-10) Severe pain | after treatment by 24 hours | 
| post-operative pain after single visit root canal treatment by NRS (numerical rating scale) | Primary outcome will be assessed by NRS (numerical rating scale), the unit of measurement is categorical.The scale is from (0-10) (1-3) Mild pain (4-6) Moderate pain (7-10) Severe pain | after treatment by 48 hours |
