Postoperative Pain
Conditions
Brief summary
The aim of the present study is to compare the effect of canal shaping using TruNatomy and RaCe rotary systems in bi-rooted maxillary premolars in terms of: * Post operative pain: incidence and intensity * Real time torque generated during mechanical instrumentation using real time torque motoring endodontic motor * Time needed for the instruments to reach to the full working length
Interventions
PROCEDURERoot canal treatment using TruNaomy rotary files
Trunatomy rotary files will be used for the process of cleaning and shaping of the root canal system
PROCEDURERoot canal treatment using race rotary instruments
Race rotary files will be used for the process of cleaning and shaping of the root canal system

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Post operative pain using visual analogue scale | at 24 hours post treatment | pain after treatment would be measured with a VAS scale from 0-10 cm with zero representing the least amount of pain and 10 representing the worst pain possible |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| operative torque generated during instrumentation | during treatment | real time operative torque exerted on the instrument through out the shaping process and until the instrument reaches the full working length will be measured using a torque measuring motor in real time |
| time required for the instrument to reach the full working length | during treatment | time required for the the instrument to reach the full length and complete the shaping process will be calculated using a Realtime torque motoring motor |
