ABSTRACT
The objective of this study were to determine which medium [normal saline or 2% chlorhexidine] is more efficient when mixed with calcium hydroxide in reduction of interappointment pain. Eighty subjects from Department of Operative and Endodontics, Sardar Begum Dental College were randomly divided into two groups; Group 1 had 40 subjects who received calcium hydroxide mixed with 2% Chlorhexidine while in group 2, the subjects received calcium hydroxide mixed with 0.9% normal saline after chemomechanical preparation. The mean pain experienced by the subjects was less in group 1 after 6, 12, 24 and 48 hours of the preparation. As intra canal dressing, combination of calcium hydroxide and chlorhexidine was more effective than that of calcium hydroxide and saline, in reducing interappointment pain
