Study Overview

Brief Summary

  • The aim of this study is comparative between:
  1. Intra-radicular cryotherapy using cold anti-inflammatory {ketorolac tromethamine at 2-5C}.
  2. Intra-radicular final flush anti-inflammatory {ketorolac tromethamine at room temperature}.
  • In terms of:

C. Level of post-operative pain {POP} using a visual analog scale {VAS}. D. Level of substance P in periapical fluid will be analyzed by enzyme-linked immunosorbent assay (ELISA) kit.

Outcomes :

  • Primary outcomes: Level of Post-operative pain.
  • Secondary outcomes: Level of substance P expression

Arms & Interventions

Intra-radicular saline at room temperature

Intervention: anti-inflammatory ketorolac tromethamine (Drug)

Outcomes

Primary Outcomes

Level of Post-operative pain.

Time Frame: 48 hours post operative

measure intensity of post operative pain using visual analogue scale that was represented by a 100 mm horizontal ruler with no number markings other than a 0 at one end and a 10 at the other end. The following categories of postoperative pain levels were used to assess pain: 0 indicating no pain, mild pain (1-3), moderate pain (4-7) and severe pain (8-10)

Level of pre-operative pain.

Time Frame: before start the operative

measure intensity of post operative pain using visual analogue scale that was represented by a 100 mm horizontal ruler with no number markings other than a 0 at one end and a 10 at the other end. The following categories of postoperative pain levels were used to assess pain: 0 indicating no pain, mild pain (1-3), moderate pain (4-7) and severe pain (8-10)

Level of Post-operative pain.

Time Frame: 6 hours post operative

measure intensity of post operative pain using visual analogue scale that was represented by a 100 mm horizontal ruler with no number markings other than a 0 at one end and a 10 at the other end. The following categories of postoperative pain levels were used to assess pain: 0 indicating no pain, mild pain (1-3), moderate pain (4-7) and severe pain (8-10)

Level of Post-operative pain.

Time Frame: 24 hours post operative

measure intensity of post operative pain using visual analogue scale that was represented by a 100 mm horizontal ruler with no number markings other than a 0 at one end and a 10 at the other end. The following categories of postoperative pain levels were used to assess pain: 0 indicating no pain, mild pain (1-3), moderate pain (4-7) and severe pain (8-10)

Level of Post-operative pain.

Time Frame: 72 hours post operative

measure intensity of post operative pain using visual analogue scale that was represented by a 100 mm horizontal ruler with no number markings other than a 0 at one end and a 10 at the other end. The following categories of postoperative pain levels were used to assess pain: 0 indicating no pain, mild pain (1-3), moderate pain (4-7) and severe pain (8-10)

Secondary Outcomes

  • Level of substance P expression.(Immediately prior to obturation)
  • Level of substance P expression.(15 minutes following access cavity preparation.)
  • Level of substance P expression.(30 minutes following access cavity preparation.)
