1/4. Human histology of new attachment after root coverage using subepithelial connective tissue graft.

    BACKGROUND, AIMS: connective tissue grafts are used successfully in periodontal therapy for root coverage. However, reports on the histologic interface between the root surface and the grafted tissue have been few in number. This report describes a case study in which a subepithelial connective tissue graft was placed in a 27-year-old female on the maxillary left side. methods: The graft (15 mm long, 10 mm wide, 1.5 mm thick) included palatal periosteum and was placed with the periosteal side facing the exposed bone and root surfaces. RESULTS: 15 weeks after grafting, the teeth presented with residual recessions of 1 mm, and buccal probing depths were approximately 1 mm. 14 months post-surgery, the 1st maxillary premolars on both sides were extracted for orthodontic therapy. Clinical parameters at the graft site remained as at 15 weeks. Histologic analysis of tooth #24 showed that the sulcular epithelium was keratinized; epithelium lining the dentin exhibited rete ridges projecting into the gingival connective tissue; and junctional epithelium extended over new cementum. New connective tissue attachment was also observed, including periodontal ligament. CONCLUSION: Biological width was comparable pre- and post-surgery, indicating a real gain in attachment of 3.9 mm.

2/4. tooth transplantation to bone graft in cleft alveolus.

    Autotransplantation of teeth has developed from a last resort operation into a well tested and relatively predictable clinical procedure. This article documents four cases where autologous teeth were successfully transplanted into bone from the iliac crest grafted to an alveolar cleft. The possibility of tooth transplantation should be considered when planning dental rehabilitation for patients with cleft.

3/4. Histologic assessment of new attachment following the treatment of a human buccal recession by means of a guided tissue regeneration procedure.

    A deep, long-standing recession on a mandibular incisor was treated in a 56-year-old female patient. The tooth was tilted buccally and was scheduled for extraction. The recession was 8 mm deep, with a pocket depth of 1 mm and no keratinized tissue. The recession was treated by guided tissue regeneration; the membrane was left in place for 4 weeks. The tooth was extracted along with marginal tissues 5 months after the removal of the membrane. At the time of extraction, 4 mm of root coverage had been achieved and 3 mm of keratinized tissue were measured buccally. Histologic measurements showed that 3.66 mm of new connective tissue attachment had been obtained associated with newly formed cementum (2.48 mm) and bone growth (1.84 mm). The crestal bone level after treatment was located coronal to the preoperative location of the gingival margin.

4/4. A new approach in restorative treatment of external root resorption. A case report.

    This case report describes the treatment of an external root resorption with extensive loss of tooth structure and bone at the labial surface of an upper left central incisor. The area of bone loss and root resorption was surgically exposed and an impression was taken using curing silicone. An individual ceramic insert was fabricated, allowing endodontic retreatment through an artificial root canal. The insert was incorporated using a dentin bonding system and a dual curing luting composite. Following endodontic retreatment and internal bleaching, a ceramic veneer was bonded to the tooth to obtain good esthetics and to improve stability. Twenty months after surgical treatment no further root resorption could be detected radiographically. A shallow residual pocket but no bleeding on probing was found.
