Design outcomes

Primary

Measure	Time frame	Description
pre-operative pain before single visit root canal treatment by NRS (numerical rating scale)	Baseline	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
post-operative pain after single visit root canal treatment by NRS (numerical rating scale)	after treatment by 6 hours	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
