Two cases of extensive gingival clefts are presented with surgical methods used for their correction. The theoretical basis for their pathogenesis is briefly described.
A histological study of the site of a clinically successful bone graft revealed the presence of a downgrowing junctional epithelium between the root surface and the altered graft bone. No new cementum could be seen associated with the osseous autograft, nor was a functional periodontal ligament in evidence adjacent to the grafted bone. It is suggested that the presence of newly formed bone on surgical reentry following bone grafting in periodontal lesions does not necessarily imply that regeneration of the periodontium has occurred.
Interproximal channeling defects associated with lingual denudation of the root are often encountered in patients with insidiously progressive chronic periodontitis. Several cases of such lesions are described and their potential for repair demonstrated. It is suggested that this type of defect is predictably amenable to successful therapy by exposure and curettage, and that restoration of lost periodontal structures can be anticipated within the interproximal portion of the lesion.
A case is presented in which an unusual amount of intraoral calculus was seen in a 59-year-old woman. The deposits completely covered all surfaces of most teeth and extended over the facial and lingual gingivae. The relationship between certain chemical salivary parameters and heavy calculus formers is briefly described.
A 48-year-old female patient presented with advanced periodontitis but was unable to proceed with periodontal therapy. After ten years of absence, her periodontal status appeared unchanged, if not slightly improved, despite the total lack of any dental or periodontal care. Studies on the biologic behavior of periodontitis are severely lacking and would appear to be a logical area for future epidemiologic surveys.

Standardized wounds were created in the femurs of 13 female white New Zealand rabbits and implanted with autogenous scleral connective tissue, Achilles bovine tendon collagen chips and cores of cancellous autogenous bone and marrow. A blood-filed wound served as a control. The dynamics of the healing of these wounds over periods of time ranging from 12 days to 3 months was studied by routine histology, fluorescent microscopy and by radiography. Rapid healing of the control and bone implant wounds occurred but was retarded by the implantation of sclera. Collagen chips provoked an active lymphocytic response and severely impeded the healing of the experimental wounds. These experiments were discussed in light of the current interest in allogenic scleral implants in periodontal therapy.
Three clinically discernable gingival cysts have been described and documented histologically. Two of these lesions occurred in the same patient in adjacent areas of the mouth. The potential origin of such cysts has been described. We suggest that gingival cysts are not clinical curiosities, as proposed in earlier reports.
