Abstract
We present two cases of apical extrusion of non-setting, calcium hydroxide paste which had been placed as an interappointment root canal dressing during routine endodontic treatment resulting in tissue necrosis of a large part of the mandible. Surgical intervention consisted of resections in both instances. In relation to the cases presented, a systematic review of similar cases in the literature between 1980 and April 2013 was conducted which resulted in eight cases meeting the criteria outlined. As with the two presented cases, half of these eight cases showed serious adverse effects and the use of an injectable system had most often been related to apical extrusion. Consequently, great care should be taken when applying the paste into the canal system.
