Evaluation of Post Operative Pain in Retreatment of Molars Using Different Irrigant

Assessment of Post Operative Pain Following Root Canal Retreatment in Molars Using Four Different Combination of Irrigants : A Prospective Clinical Study

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.

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
