A study was made to investigate the biological possibility of obtaining new connective tissue attachment to periodontally diseased root surfaces following full thickness flap procedure. Reconstructive surgery was performed on seven teeth involved in advanced chronic periodontal disease. A mucoperiosteal flap was raised and the apical extent of existing subgingival calculus was marked with a notch made into the root just apical to the calculus. Following thorough instrumentation, sterile saline was applied to the root surface for five minutes, and the flap was repositioned and sutured. Four months later the teeth with attached periodontal tissues were removed and processed for histological analysis. None of the specimens demonstrated regenerating soft connective tissue or evidence of cementogenesis coronal to the notch. The base of the junctional epithelium extended from 0.55 to 2.40 mm below the coronal aspect of the notch. Therefore, at least among these seven specimens, the biological possibility of obtaining new connective tissue attachment to diseased root surfaces following conventional full thickness flap procedures was not demonstrated.
