Effect of accidental periapical extrusion of calcium hydroxide paste [A case report]

Calcium hydroxide is an effective biocompatible substance that has been widely studied in scientific research, and is regarded as the material of choice for treating intracanal infections. The paper discusses a case of a non vital central incisor with a large periapical lesion, in which calcium hydroxide paste containing iodoform as a radiopacifier was used. There was an un-intentional extrusion of calcium hydroxide during application. The patient was seen at a regular periodic recall for one year. The followup revealed that the accidental extrusion of calcium hydroxide did not have any detrimental effect on periapical healing
