ABSTRACT
An interesting case of pyogenic vertebral osteomyelitis with multiple epidural abscesses caused by non-pigmented Prevotella oralis is reported. The patient was a 68-year-old female who presented to the emergency room (ER) with severe pain and tenderness in her lower back with fever. She had recently undergone esophagogastroduodensoscopy (EGD) for complaints of esophageal reflux, which showed submucosal cyst in the esophagus. Magnetic resonance imaging (MRI) of the thoracic spine revealed multiple spinal epidural abscesses with signal enhancement at the level of T6 and T7, suggestive of vertebral osteomyelitis. Two blood cultures drawn one hour apart grew Prevotella oralis. The body fluid aspirated from the abscesses was also positive for the anaerobic commensal P. oralis. Necrosis associated with the submucosal cyst was implicated as the cause of sepsis and osteomyelitis due to this organism.

Background : Community periodontal index of treatment needs (CPITN) index is commonly used to measure periodontal disease. It's uniqueness, apart from assessing the periodontal status, also gives the treatment needs for the underlying condition. Benzoyl-DL-arginine napthylamide (BANA) test is a chair side diagnostic test used to detect the presence of putative periodontal pathogens. We correlated the CPITN scores of patients with BANA test results to assess the validity of CPITN as an indicator of anaerobic periodontal infection. Objectives : The present study was aimed to correlate the CPITN scores with the BANA activity of subgingival plaque. The objective was to assess the validity of CPITN index as indicator of anaerobic periodontal infection. Patients and Methods : A total of 80 sites were selected from 20 patients with generalized chronic periodontitis. After measuring the probing depth with CPITN C probe, the highest score from each sextant was selected according to the CPITN criteria and subgingival plaque samples were collected using a sterile curette and the BANA test was performed. Results : Kendall's tau-b and Chi- square test were used to assess the correlation between the BANA test results and CPITN scores. Results indicated sensitivity (92.86%), specificity (80%) and agreement (91.25%); indicating the validity of CPITN in assessing anaerobic infection. Conclusion : There was a significant correlation between BANA test results and scores 3 and score 4 of CPITN index (P < 0.001) clearly indicating the presence of anaerobic periodontal infection.

Este trabalho tem por objetivo fazer revisão da literatura e relatar um caso clínico de manchas negras, possivelmente causadas pelos Bacilos produtores de pigmentos negros. Acredita-se que a presença da bactéria Prevotella melaninogênica seja fundamental para que haja este tipo de mancha no esmalte dentário, estando em maior quantidade na microflora das crianças portadoras desta pigmentação. Estas manchas extrínsecas estão sendo associadas ao índice de cárie, higiene oral e com a etiologia da doença periodontal. O caso clínico apresentado é o de uma criança com pigmentação preta no esmalte, principalmente nas faces linguais dos dentes anteriores inferiores, acometendo também de forma mais branda outros dentes da cavidade bucal. O tratamento se deu através da educação e motivação da mãe e da criança quanto a higienização e conseqüente profilaxia com jato de bicabornato.

A doença periodontal inflamatória é considerada como resultante da açäo das bactérias contidas na placa dentária. Uma vez que as bactérias inteiras näo säo encontradas na intimidade dos tecidos periodontais é provável que a doença ocorra devido à difusäo dos seus produtos através do epitélio do sulco gengival, provocando uma resposta inflamatória e imune. Assim, torna-se importante identificar esses produtos, principalmente das bactérias que predominam na placa dental, como é o caso do Bacteroides melaninogenicus e suas subespécies, que tem se distinguido como patógenos importantes na doença periodontal. O propósito deste estudo foi verificar a presença de antígenos solúveis de B. melaninogenicus subsp. intermedius nos tecidos gengivais, bem como de anticorpos séricos para o mesmo microrganismo em portadores de doença periodontal...
