The possibility of obtaining new connective tissue attachment to periodontally diseased root surfaces following replaced flap procedure was studied in seven single‐rooted teeth from six patients with advanced chronic periodontilis. Mucoperiosteal flaps were raised and supraosseous soft tissues curetted from the lesion. In order to establish a landmark for histological observations located within the periodontal pocket, a notch was made into the root just apical to existing subgingival calculus. A similarly placed notch was used in a previous report (Cole et al. 1980). Following thorough root planing, the flap was replaced and sutured. Four months later block biopsies were removed. The results demonstrated that none of the specimens showed soft connective tissue adhering to the tooth or evidence of new cementum coronal to the notch. A thin junctional epithelium had proliferated to the level of, or beyond the notch. Therefore, among these seven specimens, unequivocal proof of new attachment to diseased root surfaces following conventional full thickness flap procedures was not demonstrated. This is in contrast to the previous report (Cole et al. 1980) wherein new attachment was obtained in all of 10 specimens treated by full thickness flap surgery supplemented with citric acid conditioning of the root surface.
