title: Periodontal repair of periapical lesions: the borderland between pulpal and periodontal disease.
abstract: A series of cases demonstrating the destruction of periapical periodontal structures, without pulpal involvement has been presented. Treatment using both surgery and antibiotics resulted in extensive healing without any concommitant endodontic therapy. The results suggest that lesions affecting the apical periodontium are either periodontal or pulpal in origin. Careful diagnosis allows the maintenance of pulp vitality in cases where apical destruction has a source other than an infected pulp. The commonly held belief that lateral and accessory canals are a significant source of pulpal contamination from deep periodontal pockets has been questioned.
