Methods: Forty five patients with single rooted teeth suffering from necrotic pulp status were divided into 3 groups (n=15), the first group received mechanical preparation only , the second group received calcium hydroxide intracanal medication only, while the third group received mixture of calcium hydroxide and 2 % chlorhexidene gel intracanal medication. Numerical pain scale was used to assess the pain experience post operatively.
Results: Calcium hydroxide was superior in decreasing the postoperative pain at time interval 4 hours and 24 hours in comparison to the mixture of calcium hydroxide paste and 2 % chlorhexidene gel significantly
