Pak Oral Dental J Jan ;35(2):286-9.

The aim of this study was to compare the analgesic effects of Calcium hydroxide and Chlorhexidine as intracanal medicaments in three different groups of patients. This interventional study was conducted over a period of one year at the Department of Operative Dentistry, Fatima Jinnah Dental Hospital, Karachi. 465 single rooted teeth of patients were divided into three equal groups with 155 teeth in each group.155 canals were filled with Calcium Hydroxide, 155 canals with Chlorhexidine and another 155 canals with cotton pellets. The effectiveness of one intracanal medication versus another was checked in controlling post operative pain after endodontic treatment. The results showed that there was a significant difference between post operative pains in the three different groups. Group B (chlorhexidine) proved to be most effective against pain (22.58%) followed by group A (calcium hydroxide) (9.68%) and group C (cotton pellets) (1.29%) respectively. The McNemar Chi-Square test showed significant result with p-value<0.00. This study showed that Chlorhexidine has better analgesic effects as an intracanal medicament than Calcium hydroxide or no medication.
