Nonsurgical treatment of periapical lesions using intracanal calcium hydroxide medicament--a report of 2 cases.

Periapical pathology is the most common sequelae of pulpal necrosis due to traumatic injury. For the success of endodontic treatment, healing of periapical pathology is necessary and can be achieved by maintaining a sterile root canal system. Calcium hydroxide has the potential to maintain a sterile root canal by its antibacterial and tissue-dissolving property. Two case reports of periapical pathology that healed within a period of 3 to 6 months after intracanal calcium hydroxide dressing are presented.
