1/70. Intraosseous fibrous lesions of the jaws: a manifestation of tuberous sclerosis.

    Four patients previously diagnosed with tuberous sclerosis are reported with intraosseous fibrous lesions of the jaws. review of the literature revealed comparable pathosis occurring in extragnathic bones and several previous reports of similar lesions within the jaws. Therefore, these intraosseous fibrous proliferations are thought to represent an intraoral manifestation of tuberous sclerosis and not coincidental findings. In all 4 cases, the tumors demonstrated significant collagenization with numerous interspersed plump fibroblasts. Although histopathologically similar, the features of the lesions are not specific and also can be found in desmoplastic fibromas and simple odontogenic fibromas. The definitive diagnosis requires appropriate clinicopathologic correlation.

2/70. Cranio-facial fibrous dysplasia in a 38-year-old African woman: a case history.

    A 38-year-old woman sought treatment with cranio-facial dysplasia involving the cranium, maxilla and the mandible. Her chief complaint was a mandibular swelling, which had appeared about 2 years previously, had gradually enlarged, and was associated with spontaneous pain. x-ray film examination revealed a ground-glass opacity with blurred demarcation and a 99 Tc medronate bone scan disclosed an increase in tracer uptake in the cranium, maxilla and mandible. The rest of the skeleton was not affected. Histological examination of the lesions revealed solid proliferation of spindle-shaped cells associated with islands of osteid and bone trabecullae with Chinese letter pattern and numerous multinucleated giant cells consistent with fibrous dysplasia. The continued osteoblastic activity of involved bones, coupled with the medical condition of the patient, restricted the management of the patient to largely supportive and palliative care.

3/70. noma: report of a case resulting in bony ankylosis of the maxilla and mandible.

    noma, or cancrum oris, has been described as a gangrenous infection of the soft and hard tissues of the oronasal region. Prior to the advent of antibiotics the disease was commonly fatal. Now many survive the acute phase of the disease and present the surgeon with formidable problems of repair. This is a report of a presumed case of noma that resulted in bony ankylosis of the maxilla and mandible. Three-dimensional shaded surface CT reconstruction images were especially useful in demonstrating the architecture of the abnormal bone.

4/70. Possibilities of preventing osteoradionecrosis during complex therapy of tumors of the oral cavity.

    In recent years, there has been a dramatic increase in the number of tumors of the head and neck. Their successful treatment is one of the greatest challenges for physicians dealing with oncotherapy. An organic part of the complex therapy is preoperative or postoperative irradiation. Application of this is accompanied by a lower risk of recurrences, and by a higher proportion of cured patients. Unfortunately, irradiation also has a disadvantage: the development of osteoradionecrosis, a special form of osteomyelitis, in some patients (mainly in those cases where irradiation occurs after bone resection or after partial removal of the periosteum). Once the clinical picture of this irradiation complication has developed, its treatment is very difficult. A significant result or complete freedom from complaints can be attained only rarely. attention must therefore be focussed primarily on prevention, and the oral surgeon, the oncoradiologist and the patient too can all do much to help prevent the occurrence of osteoradionecrosis. Through coupling of an up-to-date, functional surgical attitude with knowledge relating to modern radiology and radiation physics, the way may be opened to forestall this complication that is so difficult to cure.

5/70. erdheim-chester disease of the jaws: literature review and case report.

    erdheim-chester disease is a rare systemic lipogranulomatous disorder of adults that shares some histopathologic features similar to Langerhans' cell histiocytosis and that results in characteristic radiographic changes in the long bones. Relatively few cases have been reported in the jaws. We present a literature review of jaw cases and the first case report to describe detailed radiographic and pathologic features of jaw involvement, as well as clinical, radiographic, and histopathologic follow-up of the untreated jaw lesions.

6/70. tooth eruption in a patient with craniometaphyseal dysplasia: case report.

    Craniometaphyseal dysplasia (CMD) is a very rare genetic disorder of bone remodeling caused by osteoclast dysfunction. The clinical and radiographical features of oral findings are presented in a sporadic case of CMD in a child (age 10 years, 7 months). An intraoral examination showed severe malocclusions, including anterior crossbite and deep bite. Furthermore, a radiographic examination showed increased radiopacity of the maxilla and mandibular bones due to hyperostosis and sclerosis of the jaw. There was no root resorption of the canines or molars in the primary dentition, although root formation of the permanent teeth was proceeding. Dental age was calculated to be approximately 1 year, 4 months younger than his chronological age. The eruption speed of the permanent lateral incisors after the gingival emergence was shown to be within normal values, and we discuss whether the canines and premolars in the permanent dentition could erupt or not.

7/70. Macrognathia of renal osteodystrophy in a dialysis patient. Report of a case.

    A case of macrognathia secondary to renal osteodystrophy in a dialysis patient is presented. The case reviewed demonstrates a variety of radiographic and histopathologic features, some of which resemble fibrous dysplasia and others suggestive of Paget's disease of bone. This article contains diagnostic criteria for differentiating renal osteodystrophy from similar fibro-osseous diseases. There is a discussion of the underlying cause and appropriate therapeutic interventions of renal osteodystrophy.

8/70. 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.

9/70. 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.

10/70. Preoperative application of limited cone beam computerized tomography as an assessment tool before minor oral surgery.

    We describe the preoperative application of limited cone beam computerized tomography (CT) using a Dental three-dimensional (3D)-CT as an assessment tool before minor oral surgery. The Dental 3D-CT provided 42.7 mm-high and 30 mm-wide rectangular solid images. This size covered the height of the mandible with standing teeth. Dental 3D-CT clearly demonstrated lesions in the maxillary and mandibular bone. Resorption of the bone due to disease expansion was depicted more clearly on the Dental 3D-CT than on conventional radiographs. Information about lesion location and the relationship between the lesions and their adjacent anatomical structures, such as the mandibular canal and maxillary antrum, was useful for minor oral surgery. Due to its high resolution and low radiation dose, Dental 3D-CT was useful for preoperative examination prior to minor oral surgery.
