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.


Clinical Trial 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.

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 ;
