Outcome Measures

Primary Outcomes (1)

  • Level of post operative pain

    On visual analogue scale (VAS) questionnaire, patients will report their level of pain 0° refers for no pain, and the 100° degree refers for unbearable pain

    after 6 hours, 24 hours, 48 hours, 72 hours

Secondary Outcomes (1)

  • Level of substance P

    After access cavity, after finishing mechanical perpetration, before obturation(after 3 days)

Study Arms (3)

Control Group

NO INTERVENTION

Conventional root canal treatment is done and irrigation will be done with 2.5% room temperature sodium hypochlorite

Cryotherapy Group

EXPERIMENTAL

Root canal treatment is done and irrigation is done with cooled sodium hypochlorite ( 2- 4°C) through out the visits and final flush with 2- 4°C cold saline will be used for 5 minutes.

Other: cryotherapy

Final Flush group

ACTIVE COMPARATOR

Root canal treatment is done and irrigation is done with sodium hypochlorite at room temperature through out the visits then final flush with 2- 4°C cold saline will be used for 5 minutes.

Other: cryotherapy
