Abstract
Calcium hydroxide is used extensively as an intracanal medicament in endodontics for many years. It is used in various clinical situations such as to promote apexification, to repair perforation, to enhance healing of periapical lesions, to control root resorption, and to control exudation in teeth with persistent periapical inflammation. This paper presents a case report in which Ca(OH)2 was used as an intracanal medicament for treatment of periradicular lesions using two different vehicles in two different teeth of same patient.

Summary
The main goal of endodontic therapy is to eliminate or at least achieve a significant reduction of microorganisms present in the root canal system. It is well recognized that chemomechanical instrumentation alone is unable to completely disinfect the root canal system [1]. The bacteria surviving root canal instrumentation proliferate between appointments. The use of intracanal medication with antimicrobial activity between appointments has been recommended to eliminate possible persistent microorganisms, in case of pulp necrosis with periradicular bone loss [2]. Calcium hydroxide with its antimicrobial property has been widely used in endodontics for interappointment intracanal dressing. It has been demonstrated that treatment with calcium hydroxide as an interim dressing in the presence of large and chronic periapical lesions can create an environment more favorable to healing and encourage osseous repair [3]
