1/172. Destructive membranous periodontal disease (Ligneous periodontitis).

    Generalized membranous gingival enlargement due to accumulation of amyloid or fibrin-like material is a rare, destructive and poorly defined disease entity. Some patients also show extraoral manifestations. The lesion is an involvement of periodontal tissues caused by the same process as ligneous conjunctivitis. In this report, 3 new cases, two of whom are siblings, are presented. Defective fibrinolysis and abnormal wound healing seem to be the main pathogenetic mechanism of this unusual disease, which should be evaluated systemically considering other mucosal involvement.

2/172. Microbiological features of Papillon-Lefevre syndrome periodontitis.

    Papillon-Lefevre syndrome patients exhibit hyperkeratosis palmo-plantaris and severe periodontitis. The syndrome is an autosomal recessive trait, but the mechanism of periodontal destruction is not known. This report presents the clinical and microbiological features of an 11-year old girl with Papillon-Lefevre syndrome. Clinical examination included conventional periodontal measurements and radiographic analysis. In samples from 3 deep periodontal lesions, the occurrence of major suspected periodontopathic bacteria was determined by selective and non-selective culture and polymerase chain reaction (PCR) identification, and the presence of cytomegalovirus and Epstein-Barr type 1 virus by a nested-PCR detection method. 10 of 22 available teeth demonstrated severe periodontal breakdown. Major cultivable bacteria included actinobacillus actinomycetemcomitans (3.4% of total isolates), prevotella nigrescens (16.4%), fusobacterium nucleatum (14.3%) and peptostreptococcus micros (10.6%). A. actinomycetemcomitans, P. nigrescens, porphyromonas gingivalis and eikenella corrodens were identified by PCR analysis. The patient's non-affected parents and older brother revealed several periodontal pathogens but not A. actinomycetemcomitans. The viral examination demonstrated cytomegalovirus and Epstein-Barr type 1 virus in the subgingival sample of the Papillon-Lefevre syndrome patient. The father and brother yielded subgingival cytomegalovirus but not Epstein-Barr type 1 virus. We hypothesize that human herpesviruses in concert with A. actinomycetemcomitans play important roles in the development of Papillon-Lefevre syndrome periodontitis.

3/172. Treatment of molar furcation involvement using root separation and a crown and sleeve-coping telescopic denture. A longitudinal study.

    Because of the inconsistent results of periodontal and prosthetic therapy, periodontists may choose to treat maxillary molar furcation involvements (FI) with poor root morphology utilizing a root resection technique (RRT). In addition, poor root morphology of the remaining root following RRT is usually considered a high risk factor for long-term periodontal and prosthetic success. The purpose of this retrospective study was to investigate the differences in the clinical periodontal parameters between molar abutments with and without molar root separation and/or resection (RSR) before and after periodontal and prosthetic therapy, using a crown and sleeve-coping telescopic denture (CSCTD). A total of 85 molars (47 maxillary and 38 mandibular) were treated in 25 subjects. There were 33 abutments without root separation/resection and 52 abutments with RSR. Forty-three CSCTD were placed, 23 in the maxillary arch and 20 in the mandibular arch. The mean observation period was 6.7 /-1.9 years (range, 5 to 13 years). The plaque index, gingival index, probing depth, clinical attachment level, and alveolar bone change were recorded. The differences in these parameters before and after periodontal and prosthetic therapy between the advanced furcation-involved molars with and without RSR were evaluated. The results revealed a remarkable improvement in the periodontal parameters in advanced Class II and Class III FI in molars with RSR as compared to those without RSR. It was, therefore, concluded that molar abutments with RSR in conjunction with a specifically designed telescopic device provide a modified approach for treating molars with advanced Class II and III FI.

4/172. Parosteal osteogenic sarcoma of the mandible, Existence masked by diffuse periodontal inflammation.

    A 38-year-old man was in a state of poor oral hygiene, with multiple broken carious teeth and diffuse inflammatory hyperplasia of the gingival tissues. A mandibular, alveolar soft tissue mass in the premolar-molar region was noted on the right side, in continuity with the gingival hyperplasia. biopsy of the lesion ruled out a diagnosis of squamous cell carcinoma. The patient underwent extraction of his teeth, and all hyperplastic tissues including the tumefaction were excised. Five months later, the patient had a recurrent mass in the same location that was removed via hemimandibulectomy. The mass was diagnosed as a parosteal osteogenic sarcoma.

5/172. bone regeneration following damage by polysulphide impression material. A case report.

    Two days after polysulphide rubber impressions had been taken of gold inlay cavities in 6 and 7, a 22-year-old female dental student developed a painful swelling between 5 and 6. A radiograph revealed the presence of an irregular radiopaque body within the cancellous bone of the interdental septum between 5 and 6. At operation, 1 month later, the interdental septum was seen to have been destroyed and its position occupied by impression material and inflammatory tissue. When the lesion was reopened 2 years later to correct slight recurrent pocketing, significant regeneration of bone was found to have occurred.

6/172. Comparing periodontal disease in identical twins: a case report.

    Previous investigators have shown that numerous environmental and genetic variables may contribute to the pathogenesis of periodontal disease. This case report presents clinical and laboratory findings of a set of Caucasian female identical twins. One patient presented clinically with mild gingivitis and no clinical or radiographic signs of periodontitis. The other exhibited gingivitis with localized, moderate-to-severe periodontitis. Neither patient reported a history of systemic conditions that might influence their periodontal health, and neither presented other known risk factors, such as tobacco use. The only apparent variable was related to their oral hygiene. The periodontally involved patient exhibited higher plaque scores than her twin in all clinical visits. Subgingival plaque cultures revealed the presence of porphyromonas gingivalis and bacteroides forsythus only in the diseased twin. Both patients had low colony counts of prevotella intermedia and eikenella corrodens, but only the healthy twin harbored small quantities of fusobacterium nucleatum. This case report offers an opportunity to assess etiology of periodontitis in two genetically identical patients whose only obvious difference was their oral hygiene.

7/172. Leukocyte functions in 2 cases of Papillon-Lefevre syndrome.

    AIM: To investigate the role of leukocytes in the pathogenesis of Papillon-Lefevre syndrome (PLS). methods: Peripheral blood polymorphonuclear neutrophils (PMNs), monocytes (MNs) and gingival crevicular fluid (GCF) were obtained from 2 cases of PLS with typical features. The chemotaxis of PMNs and MNs were evaluated using a modified Boyden chamber. The adherence of PMNs was determined by adherence of PMNs to petri dishes. interleukin-8 (IL-8) in GCF was detected by sandwich ELISA. Elastase activity in GCF was measured with a low molecular weight substrate (S-2484) specific for granulocyte elastase. RESULTS: PMNs from both patients showed depressed chemotactic response to FMLP and IL-8. Total amounts of IL-8 in GCF from the 2 patients were much higher than those of the normal controls. Elastase activity was not significantly different from that of the controls. The adherence of PMN and the chemotaxis of MN in the 2 patients were normal. CONCLUSION: The depressed chemotactic response of PMN leads to decreased recruitment of PMN and/or release of lysozyme from PMN in the diseased gingival tissue, increasing the susceptibility of PLS patients to periodontal infection.

8/172. Implant site development using orthodontic extrusion: a case report.

    One of the most important factors in the successful placement of endosseous implants is the presence of adequate alveolar bone at the recipient site. alveolar bone loss associated with destructive periodontal disease frequently results in osseous defects that may complicate subsequent implant placement. Typically, such defects are treated prior to or at the time of implant surgery using the principles of guided bone regeneration. Under certain circumstances, however, such defects may be managed non-surgically by orthodontic extrusion. orthodontic extrusion can be used to increase the vertical bone height and volume and to establish a more favourable soft-tissue profile prior to implant placement. The addition, the increase in the vertical osseous dimension at interproximal sites may assist in the preservation of the interdental papillae and can further enhance gingival aesthetics. This report illustrates the treatment sequence for site development with orthodontic extrusion prior to immediate implant placement.

9/172. 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.

10/172. actinobacillus actinomycetemcomitans-associated peri-implantitis in an edentulous patient. A case report.

    BACKGROUND: peri-implantitis is a risk factor for implant loss. Late bacterial infection of the peri-implant tissues and loss of alveolar bone in edentulous patients is caused by commensal oral anaerobic bacteria. In partially edentulous patients, porphyromonas gingivalis and occasionally actinobacillus actinomycetemcomitans are associated with peri-implantitis lesions. AIMS: To investigate the microbiology of a peri-implantitis case in an edentulous patient. methods: Anaerobic culture techniques and selective culture techniques for A. actinomycetemcomitans were used to study the peri-implant microflora at sites with and without bone loss. RESULTS: An anaerobic peri-implant microflora with several putative periodontal pathogens was found at sites with bone loss. Furthermore, a metronidazole-resistant A. actinomycetemcomitans was isolated. The A. actinomycetemcomitans infection did not respond to systemic doxycycline therapy, despite good susceptibility in vitro. CONCLUSIONS: The present case of severe A. actinomycetemcomitans-associated peri-implantitis shows the importance of pre-operative infection control. The findings in this case show that remaining teeth affected by periodontitis can be a serious risk factor for peri-implantitis.
