1/75. Histological investigation of the tissue response to hydroxyapatite used as an implant material in periodontal treatment.

    patients with severe periodontitis and who had one or more teeth with infrabony pockets were treated by periodontal surgery with implantation of hydroxyapatite particles into the bone defects at the time of surgery. Subsequently, in three patients it was found necessary to extract a tooth for reasons not related to the previous periodontal treatment. Specimens that included the local soft tissues and crestal bone attached to the teeth were obtained at 22, 40 and 80 weeks after placement of the implant. They were decalcified and stained with haematoxylin and eosin and examined under light microscopy. The healing response was found to vary between specimens, and between sites within the same specimen. The early stage of healing showed the implant particles surrounded by collagen. Subsequently, varying degrees of resorption of the periphery of the particles was seen, and at some sites bone deposition was observed. These different healing responses were found to be progressing concurrently at sites in close proximity. Further work is needed to confirm the histological findings described in the paper.

2/75. Leukocyte adhesion deficiency in a child with severe oral involvement.

    Leukocyte adhesion deficiency is a rare inherited defect of phagocytic function resulting from a lack of leukocyte cell surface expression of beta2 integrin molecules (CD11 and CD18) that are essential for leukocyte adhesion to endothelial cells and chemotaxis. A small number of patients with leukocyte adhesion deficiency-1 have a milder defect, with residual expression of CD18. These patients tend to survive beyond infancy; they manifest progressive severe periodontitis, alveolar bone loss, periodontal pocket formation, and partial or total premature loss of the primary and permanent dentitions. We report on a 13-year-old boy with moderate leukocyte adhesion deficiency-1 and severe prepubertal periodontitis. This case illustrates the need for the dentist to work closely with the pediatrician in the prevention of premature tooth loss and control of oral infection in these patients.

3/75. Long-term follow-up of periodontitis in a patient with chediak-higashi syndrome. A case report.

    chediak-higashi syndrome (CHS) is an extremely rare hereditary disease characterized by leukocyte dysfunction. We report on a 21-year-old woman who presented at the age 9 years with CHS and serious periodontal tissue destruction around erupted teeth. The patient had received systemic, radiographic, immunological, microbial, and clinical periodontal examinations since childhood. The chemotactic activity of neutrophils in the Boyden chamber assay was 22% of the control, and leukocyte bactericidal activity was one-third of the control. actinobacillus actinomycetemcomitans, porphyromonas gingivalis, and prevotella intermedia were isolated from periodontal pockets. Periodontal treatment including oral hygiene was provided, followed by professional tooth cleaning from the age of 12 to 21 years. However, the mobility of teeth and the inflammation of periodontal tissue progressed. This CHS patient presented with periodontal disease of extremely early onset, which was resistant to periodontal treatment.

4/75. Ridge preservation of dentition with severe periodontitis.

    Severe loss of alveolar bone height and width can occur following the removal of teeth with advanced periodontitis. This compromise of the alveolar bone can limit the options available for achieving an acceptable dental restoration. Two case reports are presented of alveolar ridge augmentation after tooth removal and before implant placement using bone grafting and a biodegradable membrane. The resultant alveolar ridges in both patients were adequate for the placement of dental implants.

5/75. Ehlers-Danlos type VIII. review of the literature.

    Ehlers-Danlos type VIII is a rare disorder characterized by soft, hyperextensible skin, abnormal scarring, easy bruising, and generalized periodontitis with early loss of teeth. To illustrate the clinical dermatological and dental features, we present the case history of a 20-year-old patient who has suffered from poor healing of wounds at the shins and knees since childhood, which have developed into hyperpigmented atrophic scars. In the course of orthodontic treatment during the last 3 years, severe apical root resorption, gingival recession, and loss of alveolar bone were observed. family history was noncontributory for any skin or tooth disorders. The typical clinical signs confirmed the diagnosis of ehlers-danlos syndrome type VIII. As there is no specific treatment for the disorder, management is limited to the symptomatic treatment of the dental disease. It seems advisable to consider carefully the indications for orthodontic treatment in patients with Ehlers-Danlos type VIII syndrome.

6/75. Periodontal signs and symptoms associated with vertical root fracture.

    This report describes the clinical presentation of three cases of vertical root fractures in adult patients where an initial diagnosis of localized periodontitis had been considered. Loss of the affected tooth occurred in all of these patients. The effects of endodontic therapy and the provision of post-retained restorations are considered in relation to their potential effect of weakening the root and predisposing the tooth to vertical fracture. The last case presents an unrestored molar tooth with a complete vertical root fracture.

7/75. Palatal radicular multigrooves associated with severe periodontal defects in maxillary central incisors.

    BACKGROUND: This case report describes a rare condition of palatal radicular multigrooves on teeth 11 and 21 with severe periodontal defects and the findings at 3-year follow-up. METHOD: Radiculoplasty using hand curettes and rotary burs were used to remove the multigrooves on the root surfaces and change the wrinkled root form to the relatively flat and smooth normal root morphology. Minor tooth movement and frenotomy were performed for a diastema between teeth 11 and 21. Supportive periodontal therapy started immediately after completion of the active treatment. RESULTS: Improved healthy periodontal tissues and adequate plaque control have been maintained.

8/75. Clinical application of a new compact computed tomography system for evaluating the outcome of regenerative therapy: a case report.

    BACKGROUND: The limitations of conventional 2-dimensional (2-D) radiographs have been emphasized in many studies. Because the image is a 2-D map of the 3-dimensional (3-D) tooth and periodontal tissue, these structures may be superimposed on each other. Recently, 3-D image analysis by computed tomography (CT) was introduced to dentistry, but it has been used only rarely in the periodontal field. methods: The purpose of this case report was to introduce the clinical application of a newly developed, compact computed tomography system for evaluating the outcome of regenerative therapy in an adult patient with periodontitis (male, aged 55 years). To evaluate the bone defects including furcation involvement, we took an intraoral radiograph and performed CT scanning on tooth #19. We recorded a number of clinical parameters at the time of surgery. We compared the images of the bone defect obtained by CT images and the conventional radiograph with the true bone defect morphology at the surgical site. RESULTS: One year after the periodontal surgery, we again took CT scans and a conventional radiograph, and the new images of the bone defect were compared and evaluated. The new CT images were reconstructed for 3-D evaluation and compared with those taken before surgery. The CT provides 3-D images of excellent quality for evaluating the morphology of the periodontal bone defect and furcation involvement. CONCLUSIONS: We consider that CT is a useful aid in periodontal examination and diagnosis, and in the prediction and evaluation of periodontal treatment outcomes.

10/75. Septic pulmonary embolism associated with periodontal disease: reports of two cases and review of the literature.

    We report two cases of septic pulmonary embolism associated with periodontitis. Chest CT revealed multiple nodular shadows with features characteristic of septic pulmonary embolism in both patients. Both patients had toothache, fever, and chest pain, and showed findings of periodontitis at initial presentation. Antimicrobial agents combined with dental surgery were successful in treatment. While septic pulmonary embolism from the lesions of periodontitis appears to be rare, periodontitis remains important in the differential diagnosis of septic pulmonary embolism.
