[Reattachment or new attachment in apical-marginal periodontal bone loss. A clinical-histological discussion].

Abstract

Loss of marginal alveolar bone of the tooth can be caused by periodontal, pulpal-periapical, or a combined pulpal and periodontal disease. The regeneration is supported by the formation of reattachment or new attachment. Reattachment is probably the usual healing process in periapical surgery of the tooth with apicomarginal bone loss caused by pulpal-periapical disease. In animal experiments (rats, dogs) ist was well documented, that the cells which repopulate the periodontal wound adjacent to the root surface determine the nature of the attachment formed.
