Brief Summary:
This study evaluates the efficacy of dexamethasone as a intracanal irrigant along with sodium hypochlorite 1% and 5.25% concentrations in post treatment pain for molar root canal retreatment.

Condition or disease Intervention/treatment Phase
Root Canal Infection Drug: Sodium Hypochlorite Phase 1

Detailed Description:

Main objective of root canal retreatment is to alleviate pain and disinfect the rootcanal .However some patients may experience mild to severe pain following treatment , which leads to intake of painkillers orally for post operative pain management.

So , this study evaluates the efficiency of dexamethasone used as intracanal irrigant in post treatment pain for molar root canal retreatment sodium hypochlorite (1% &5.25%) is used for disinfecting the canals patients will be grouped into Symptomatic and Asymptomatic patients requiring root canal retreatment and irrigants will be used in various combinations as mentioned below

  1. 1% sodium hypochlorite alone 2.5ml in each canal along with ultrasonic activation
  2. 1% sodium hypochlorite and dexamethasone 4mg,2.5ml in each canal along with ultrasonic activation
  3. 5.25% sodium hypochlorite alone 2.5ml in each canal along with ultrasonic activation
  4. 5.25% sodium hypochlorite and dexamethasone 4mg, 2.5ml in each canal along with ultrasonic activation calcium hydroxide is commonly used as intracanal medicament in all the patients post operative symptoms is evaluated at 12 hrs , 24 hrs,48 hrs, 72 hrs and 1 week followed by obturation is completed

Arm Intervention/treatment
Experimental: 1% sodium hypochlorite & dexamethasone 4mg as irrigants
sodium hypochlorite is effective in any concentration as antimicrobial irrigant and dexamethasone is anti inflammatory drug
Drug: Sodium Hypochlorite
Sodium hypochlorite is used as intracanal irrigant to minimize the post operative pain

Active Comparator: 1% sodium hypochlorite as irrigant &normal saline as placebo
sodium hypochlorite is effective in any concentration as irrigant
Drug: Sodium Hypochlorite
Sodium hypochlorite is used as intracanal irrigant to minimize the post operative pain

Experimental: 5.25% sodium hypochlorite and dexamethasone 4mg as irrigants
sodium hypochlorite is effective in any concentration as antimicrobial irrigant and dexamethasone is anti inflammatory drug
Drug: Sodium Hypochlorite
Sodium hypochlorite is used as intracanal irrigant to minimize the post operative pain

Active Comparator: 5.25% sodium hypochlorite &normal saline as placebo
sodium hypochlorite is effective in any concentration as irrigant
Drug: Sodium Hypochlorite
Sodium hypochlorite is used as intracanal irrigant to minimize the post operative pain




Primary Outcome Measures :
  1. post operative pain evaluation using various combination of irrigants: VAS score [ Time Frame: At 6 hours ]
    pain scale is evaluated using VISUAL ANALOG SCALE (VAS) score (1-10) 1 is minimum amount of pain experienced and 10 is maximum amount of pain experienced [1-3] mild pain , [4-7] moderate pain , [8-10] severe pain .

  2. post operative pain evaluation using various combination of irrigants: VAS score [ Time Frame: At 12 hours ]
    pain scale is evaluated using VISUAL ANALOG SCALE (VAS) score (1-10) 1 is minimum amount of pain experienced and 10 is maximum amount of pain experienced [1-3] mild pain , [4-7] moderate pain , [8-10] severe pain .

  3. post operative pain evaluation using various combination of irrigants: VAS score [ Time Frame: At 24 hours ]
    pain scale is evaluated using VISUAL ANALOG SCALE (VAS) score (1-10) 1 is minimum amount of pain experienced and 10 is maximum amount of pain experienced [1-3] mild pain , [4-7] moderate pain , [8-10] severe pain .

  4. post operative pain evaluation using various combination of irrigants: VAS score [ Time Frame: At 48 hours ]
    pain scale is evaluated using VISUAL ANALOG SCALE (VAS) score (1-10) 1 is minimum amount of pain experienced and 10 is maximum amount of pain experienced [1-3] mild pain , [4-7] moderate pain , [8-10] severe pain .

  5. post operative pain evaluation using various combination of irrigants: VAS score [ Time Frame: At 72 hours ]
    pain scale is evaluated using VISUAL ANALOG SCALE (VAS) score (1-10) 1 is minimum amount of pain experienced and 10 is maximum amount of pain experienced [1-3] mild pain , [4-7] moderate pain , [8-10] severe pain .

  6. post operative pain evaluation using various combination of irrigants: VAS score [ Time Frame: After 7 days ]
    pain scale is evaluated using VISUAL ANALOG SCALE (VAS) score (1-10) 1 is minimum amount of pain experienced and 10 is maximum amount of pain experienced [1-3] mild pain , [4-7] moderate pain , [8-10] severe pain .


Secondary Outcome Measures :
  1. assessment of other variables in pain scale [ Time Frame: through study completion, an average of 1 week ]
    comparing the pain scale experienced between male and female in VAS score

  2. assessment of other variables in pain scale [ Time Frame: through study completion, an average of 1 week ]
    comparing the pain scale experienced between mandibular molar and maxillary molar from VAS score

  3. assessment of other variables in pain scale [ Time Frame: through study completion, an average of 1 week ]
    comparing the pain scale based on patients pre operative symptom ex; patient is symptomatic or Asymptomatic before treatment procedure
