The aim of the present study was to compare periodontal healing after successive removal of periodontal tissue components, from the alveolar bone to the dentin surface. The prevailing tissue reaction when adhering PDM was left on the exposed roots was that most of the bone tissue that had been removed from the buccal surfaces had regenerated and the integrity of the PDM between the new alveolar bone and cementum surface had been reestablished. On exposed etched cementum surfaces, 2 prevailing healing results were recorded. In half the number of the roots, the root surfaces were covered by connective tissue with fibers running parallel to the root surfaces in a capsule‐like arrangement. The other prevailing reaction was a thin epithelial cell‐lining running parallel to the root surfaces in close contact or partly penetrating the adjacent connective tissue. On exposed denuded dentin surfaces, gingival retraction was a constant finding, associated with an epithelial cell‐lining of varying thickness sometimes with rete pegs and cyst‐like formations. Gingival retraction was also a constant finding on etched dentin surfaces. This was associated with pathological pockets outlined by epithelial cell‐layers of varying thicknesses. The significance of these findings were discussed with special emphasis on dynamics of recurrent periodontitis.
