1/3. 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.

2/3. 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.

3/3. Infective endocarditis due to fusobacterium nucleatum: case report and review of the literature.

    endocarditis caused by fusobacterium nucleatum is exceedingly rare. We report a case of F. nucleatum right-sided endocarditis in a patient with no known intravenous drug abuse. A detailed computer and manual search of the literature using Med-Line and Index Medicus, respectively, revealed a total of five cases of endocarditis due to this species. The clinical characteristics and the patient's hospital course are summarized and reviewed.
