“…There was also a significant gain of attachment as a result of surgical treatment in both groups, but the difference between the two groups was not statistically significant. Frank et al,7 in their histological study of human specimens after flap surgery, have shown that the new attachments primarily are made of long junctional epithelium. Caton and Zander,8 in their study in which they performed periodic root planing and soft tissue curettage in animals, have shown basically the same results.…”

Twelve patients with localized advanced periodontitis were selected for this study. The 18 teeth used were divided into experimental and control groups. In both groups the loss of attachment and pocket depth were measured and modified Widman flap surgery was performed. In the experimental group, after root planing, a number of shallow horizontal grooves were made on the root surface to roughen them. Four months after surgery the same measurements were made. The results indicated that in both groups the pocket reduction and the gain of attachment were statistically significant. The differences between the two groups, as far as pocket reduction and gain of attachment are concerned, were not significant.

“…Only recently has research been extended to the level of electron microscopy. With respect to epithelium, Listgarten (1967Listgarten ( , 1972Listgarten ( , 1972a and Frank et al (1972Frank et al ( , 1974 described reattachment to the tooth surface after gingival surgery. It is clear from these studies that a new junctional epithelium can form on the surface of hoth dentin and cementum.…”

Regeneration of periodontal connective tissue attachment was studied at the ultrastructural level in cats following the removal of cementum and superficial dentin through a surgically created fenestration in the facial alveolar plate. Non‐decalcified specimens were examined 33, 45, 70, and 105 days after surgery. In early stages of healing, fibroblasts were aligned parallel, and immediately adjacent, to the cut, irregular dentin surface; subsequently, collagenous matrix formation was observed at this site. Some regions of the defects showed surface demineralization and extension of collagen into dentinal tubules. The first indication of cementum mineralization was the deposition of small crystallites along the irregularities of the dentin surface. After further development, a well‐defined zone containing c1osel packed crystallites was usually evident at the new dentin‐cementum junction. Peripheral to this, collagen orientation in the calcified cementum was primarily parallel to the tooth surface, with some perpendicular orientation suggestive of Sharpey's fiber formation. Collagen‐mineral patterns typical of the normal cementum surface were observed, and cementoblasts were seen in various stages of inclusion into the calcified matrix. Where the injury had not reached the dentin, collagen fibrils of new and old cementum were interwoven, and the junctional region demonstrated incomplete mineralization.

“…This was lower than the values reported by Lindhe and co‐workers, who found an average 250 μm, ranging from 200 to 400 μm . According to Frank, the PDL is 100–380 μm thick , whereas DuBrul reports values of about 100 to 200 μm . The relative thin PDL found in our material could be due to exclusion of periodontally diseased teeth and the relatively small age range of the sample.…”
