11/69. Subperiosteal connective tissue grafts for pocket reduction and preservation of gingival esthetics: a case report.

    BACKGROUND: Clinical studies and recent histological evidence following mucogingival surgery for the treatment of gingival recession have documented that when closely adapted to a previously exposed root surface, connective tissue is capable of forming a new attachment. Despite these findings, no clinical tests have been conducted to examine the ability of connective tissue to reduce probing depth (PD) and increase clinical attachment levels (CAL) when it is implanted into periodontal osseous defects. The purpose of this paper is to report the clinical results on a patient following 2 subperiosteal connective tissue grafts. methods: Subperiosteal connective tissue grafts were placed in 2 sites of periodontal bone loss and deep pocketing in one patient. Following flap reflection and root preparation, a connective tissue graft 1.5 to 2.0 mm in thickness was draped and sutured over each osseous defect and then completely covered by the external flap. RESULTS: Ten months following subperiosteal connective tissue grafting, tooth #7 had 4 mm of CAL gain. tooth #10 had 3 mm of CAL gain 8 months postoperatively. Both teeth had 1 mm gain in gingival recession. Both teeth probed 3 mm postoperatively. CONCLUSIONS: When connective tissue was grafted into 2 periodontal osseous defects, there were significant reductions in probing depth and gains in CAL. There was minimal postoperative gingival recession. The new clinical attachment gain remained stable for 8 to 10 months following subperiosteal connective tissue grafting.

12/69. Periodontal and alveolar bone abnormalities associated with pachydermoperiostosis.

    Pachydermoperiostosis (PDP) is an unusual syndrome manifested clinically by finger clubbing, extremity enlargement, hypertrophic skin changes, and periosteal bone formation. A rare case of pachydermoperiostosis (primary hypertrophic osteoarthropathy) with oral manifestations in a 47-year-old man is presented. The possible correlation between physiological mechanisms of this disease and their influence on oral periodontal tissues and alveolar bone is discussed.

13/69. Periodontal healing in humans using anorganic bovine bone and bovine peritoneum-derived collagen membrane: a clinical and histologic case report.

    The authors report the clinical and histologic data on the healing of a severe periodontal lesion obtained in a one-walled intrabony defect using anorganic bovine bone under a bovine peritoneum-derived collagen membrane. Eight months after surgery, a bone-like tissue replaced the lost tissues. A biopsy of this tissue was carried out. In the part of the specimen closer to the residual bony wall of the original defect, anorganic bone particles (ABP) appeared to be surrounded by a layer of newly formed bone; its osteocyte lacunae were colonized by osteocytes from the host, and actively secreting osteoblasts were observed in many microscopic fields. No resorption phenomena were observed in the ABP Newly formed cementum with actively secreting cementoblasts was present on the tooth surface, and well-oriented fibers inserting in both newly formed cementum and bone were observed. In an area far from residual bone, all ABP did not appear to be surrounded by newly formed bone. Osteocytic lacunae appeared not to be colonized by cells, and ABP was surrounded by dense connective tissue without osteoblasts near the grafted particles. A very limited amount of newly formed bone, without relations with ABP, was observed close to the root surface. From a clinical point of view, anorganic bone in association with a collagen membrane can be effective in the treatment of bony defects characterized by an unfavorable architecture. From a histologic point of view, the clinical appearance of bone regeneration is not always confirmed in the part of the defect far from the bony walls.

14/69. A possible "rescue" procedure for dental implants with a textured surface geometry: a case report.

    dental implants with textured surfaces are a valuable adjunct in restoring edentulous sites of poor bone quality and quantity, but on occasion may become denuded of bone and require "rescue." We report here the successful management of an intrabony crater affecting a single porous-surfaced dental implant using a combination of citric acid decontamination and grafting with freeze-dried, demineralized allograft covered with a barrier of calcium sulfate.

15/69. Periodontal regeneration with an autogenous bone-Bio-Oss composite graft and a Bio-Gide membrane.

    This study evaluated the clinical, radiographic, and histologic response to the composite use of Bio-Oss porous bone mineral and autogenous bone in combination with a Bio-Gide bilayer collagen membrane to achieve regeneration when treating human periodontal bone defects. Preoperative recordings for four treatment areas included radiographs, clinical probing depths, and attachment levels; these recordings were repeated at 9 months. Histologic evaluation revealed new cementum with inserting collagen fibers and new bone formation on the surface of both types of graft materials. This grafting combination not only compared favorably with the previous use of Bio-Oss and Bio-Gide, but exceeded that result with almost complete periodontal regeneration. This human histologic study demonstrates that autogenous bone in combination with porous bone mineral matrix, together with the Bio-Gide collagen membrane, has the capacity to stimulate substantial new bone and cementum formation with Sharpey's fiber attachment.

16/69. A concept for the treatment of various dental bone defects.

    Untreated dental bone defects usually lead to resorption of alveolar bone. Filling these defects with bone substitute material prevents resorption of bone, preserves the alveolar ridge, and provides sufficient bone for immediate or subsequent implant placement. A variety of bone substitutes is available. They differ in origin, consistency, particle size, porosity, and resorption characteristics. We have treated almost 1000 bony defect sites in 267 patients with the bone regeneration material Cerasorb. Being resorbed simultaneously with the formation of new bone, it is completely replaced by the patient's own vital bone within 6 to 12 months. The representative cases described in this paper demonstrate the successful use of the pure-phase beta-tricalcium phosphate ceramic in the treatment of all dental bone defects.

17/69. Treatment of Papillon-Lefevre syndrome periodontitis.

    BACKGROUND, AIMS: Conventional mechanical treatment of Papillon-Lefevre syndrome periodontitis has a poor prognosis. This report describes an effective antimicrobial treatment of rapidly progressing periodontitis in an 11-year old girl having Papillon-Lefevre syndrome. METHOD: Clinical examination included conventional periodontal measurements and radiographic analysis. Occurrence of major suspected periodontopathic bacteria was determined by selective and non-selective culture and by polymerase chain reaction (PCR) identification. Presence of cytomegalovirus and Epstein-Barr type 1 virus was determined by a nested-PCR detection method. Therapy included scaling and root planing, oral hygiene instruction, and systemic amoxicillin-metronidazole therapy (250 mg of each/3 times daily/10 days) which, based on follow-up microbiological testing, was repeated after 4 months. Supportive periodontal therapy took place at 2 visits during a 16-month period. RESULTS: At baseline, 10 of 22 available teeth demonstrated severe periodontal breakdown. At 16 months, probing and radiographic measurements revealed no teeth with additional attachment loss, and several teeth exhibited significant reduction in gingivitis and pocket depth, increase in radiographic alveolar bone height and clinical attachment level, and radiographic evidence of crestal lamina dura. Baseline subgingival microbiota included actinobacillus actinomycetemcomitans (3.4% of total isolates), prevotella nigrescens (16.4%), Fusobacteriumnucleatum (14.3%) and peptostreptococcus micros (10.6%), as well as cytomegalovirus and Epstein-Barr type 1 virus. At termination of the study, culture and PCR examinations showed absence of A. actinomycetemcomitans, P. micros and herpesviruses, and P. nigrescens and F.nucleatum each comprised less than 0.1 % of subgingival isolates. CONCLUSION: This study suggests that controlling the periodontopathic microbiota by appropriate antibiotic and conventional periodontal therapy can arrest Papillon-Lefevre syndrome periodontitis.

18/69. Orthodontic movement into bone defects augmented with bovine bone mineral and fibrin sealer: a reentry case report.

    Periodontal disease can lead to migration of anterior teeth with the presence of infrabony defects. This creates the opportunity for treating such patients with a combined orthodontic-periodontic treatment. In the presented clinical case, an adult periodontal patient with extrusion of the maxillary central incisors and an infrabony defect on their lingual aspects was treated. During the surgical procedure, the bone defects were augmented with a combination of porous bovine bone mineral (Bio-Oss) and a fibrin-fibronectin sealing system (Tissucol). Ten days after surgery, the active orthodontic treatment started, and the teeth were intruded and realigned, moving the roots into the defects. After 6 months, the orthodontic appliances were removed and the teeth were retained by means of a resin-bonded splint. At this time, reduction in probing pocket depth and gingival recession was detected. Twelve months after the initial surgery, a reentry procedure was performed, showing complete filling of the predisposing defects with the presence of bone-like hard tissue. These clinical results suggest that teeth can be successfully moved and intruded into bone defects previously augmented with bovine bone substitute and fibrin glue. During the orthodontic treatment, this combined augmentation material was able to be replaced by bone-like hard tissue. At the end of the therapy, an improvement in esthetics and periodontal health status was registered.

19/69. Treatment of periodontal disease in a patient with ehlers-danlos syndrome. A case report and literature review.

    BACKGROUND: ehlers-danlos syndrome (EDS) designates a heterogeneous group of connective tissue disorders characterized by skin elasticity, tissue fragility, and chronic joint pain. Dental findings have been reported with some types of EDS. This case report describes the periodontal findings in a patient with a previously undiagnosed EDS type VIII. methods: Diagnostic aids utilized included microbial testing, histological examination, gingival crevicular fluid (GCF) analysis for the levels of C-telopeptide pyridinoline cross-links (ICTP), and genetic counseling. Periodontal treatment consisted of mechanical debridement and adjunctive antibiotic therapy. RESULTS: genetic counseling and clinical presentation confirmed the diagnosis of EDS type VIII. Periodontal treatment led to marked clinical improvements and GCF levels of the bone resorptive marker ICTP were significantly reduced. The patient and her siblings are currently pursuing appropriate medical care and genetic counseling. CONCLUSION: Periodontal involvement may lead to the diagnosis of an underlying systemic condition. Identification of suspected etiological factors of periodontal disease may prove critical for the general well-being of some patients.

20/69. Unusual surgical approach in a bilateral case of mandibular buccal infected cyst.

    In the new edition of WHO's "Histological typing of odontogenic tumors", the mandibular infected buccal cyst, that is associated with the lower first or second permanent molars, is considered a paradental cyst as well as the inflammatory collateral cyst, which is usually related to the lower third molar. The lesion occurs on the buccal and lateral aspects of the roots of mandibular molars with vital pulp, at the eruption time, in children aged between 6 and 10 years. The inflammation is always present in these cysts and may have an important role in their pathogenesis because it stimulates hyperplasia and cystic change of the reduced enamel epithelium or the epithelial cell rests of Malassez. The authors report the case of a 7-year-old girl, in whom both first mandibular molars were affected by an infected buccal cyst. A different surgical approach was performed with marsupialization on the left side and cystectomy on the right side. The case reported here seems to be interesting because it is the second well documented case of bilateral mandibular infected cyst associated with unerupted molars and because the adopted treatment differs from the therapeutical approach suggested in the literature. A 6-year follow-up demonstrates a correct dental and bone evolution on both mandibular molar sides.
