Objetivo: Detectar a existência de associação entre doença periodontal ativa (DP) e ocorrência de Síndromes Coronárias Agudas (SCA). Casuística e Método: Foram avaliados 361 pacientes (57,3% do sexo masculino), com idades variando de 27 a 89 (média&#61617;DP=60,5&#61617;12,2 anos) internados na Unidade de Tratamento Intensivo de um Hospital de Ensino com quadro clínico e complementar de SCA. Todos foram submetidos a exame periodontal completo, no próprio ambiente da UTI sendo que 325 (90,0%) realizaram cinecoronariografia para confirmação diagnóstica e/ou programação de conduta terapêutica. O exame periodontal consistiu na avaliação de todos os dentes presentes na cavidade oral e dos seguintes parâmetros: profundidade clínica de sondagem, nível de inserção clinica, índice de placa e índice gengival. Resultados: Dos 325 pacientes, 91 (28,0%) apresentavam artérias coronárias isentas de obstrução ou com obstruções discretas (<= 50% de perda de diâmetro), havendo obstruções importantes nos 72,0% restantes. O teste exato de Fisher mostrou valor de P de 0,0245 e ODDS Ratio de 2,571 (IC 95% 1,192 a 5,547), ou seja, documentou-se cerca de 2,5 vezes mais possibilidade de presença de DP ativa no grupo com SCA e coronariopatia obstrutiva significante. Conclusão: Constatou-se associação significante entre presença de doença periodontal ativa e doença coronária obstrutiva de grau importante em pacientes com Síndrome Coronária Aguda, reforçando a importância da prevenção e tratamento adequado da doença periodontal, que deve ser considerada como fator de risco potencial na etiologia e na instabilização da placa aterosclerótica. Abstract Positive association between periodontal disease and coronary diseases is unclear concerning physiopathologic mechanisms and causal relationship. The aim of this study was to assess the association between active periodontal disease active and obstructive coronary artery disease in patients with acute coronary syndromes. Method: 361 (57.3% males; mean age 60.5+12.2) patients referred for diagnostic coronary vessel disease were assessed for periodontal disease and also submitted to coronary angiography with diagnostic and prognostic purposes. Each patient underwent a full-mouth periodontal examination which included gingival bleeding, plaque index, periodontal pocket depths, attachment levels and missing teeth. For statistical analysis was used the Exact Fisher test and was accepted an Alfa error of 5%. Results: 28% patients haven t significant coronary vessel obstructions (<50% diameter obstruction) and 72.0% had significant obstructive disease (>50% diameter obstruction). The Exact Fisher Test showed p-value of 0.0245 and ODDS Ratio of 2.571 (95%CI from 1.192 to 5.547). So there was a 2.5 fold increase in the chance for active periodontal disease in patients with significant obstructive coronary artery disease. Conclusion: Our study indicates a positive and significant association between periodontal disease and obstructive coronary disease among patients with acute coronary syndromes becoming periodontal disease as a potential risk factor in etiology and outcome of atherosclerotic plaque. Results of this and other investigations should be taken into account in the future researches in order to validate this association. / Ainda permanecem controvérsias quanto à ligação causal e mecanismos fisiopatológicos que expliquem a associação entre Doença Periodontal e Doenças Cardiovasculares.

Estudos têm reportado o impacto periodontite na aterosclerose. Neste estudo verificamos a associação determinando alguns marcadores de risco para aterosclerose, e verificarmos a influência do tratamento periodontal sobre esses marcadores. Quarenta pacientes com periodontite e 40 sem periodontite foram incluídos. Colesterol Total, e frações, triacilglicerol (TG), níveis de citocinas, anticorpos anti-oxLDL, proteína C Reativa (PCR), contagem de leucócitos e neutrófilos, e índice de refração foram investigados. Interleucina (IL)-6, -8 e PCR, anticorpos anti-oxLDL, TG e contagem de leucócitos e neutrófilos foram maiores em pacientes com periodontite. Os pacientes com periodontite passaram por tratamento periodontal. Novas coletas foram feitas após 3, 6 e 12 meses após o tratamento. Um ano após o tratamento, as concentrações de TG, IL-6, -8, PCR, contagem de leucócitos e neutrófilos e anticorpos anti-oxLDL foram significantemente menores. Nossos resultados confirmam que o tratamento periodontal induz mudanças sistêmicas em vários marcadores de risco para aterosclerose. / Studies have reported the impact of periodontitis on atherosclerosis. In this study we verify the association by determining some of risk markers for atherosclerosis, and we verify the effect of periodontal treatment on these risk markers. Forty patients with chronic periodontitis and 40 without periodontal disease were included. Total cholesterol and fractions, triacyglycerol (TG), levels of cytokines, antibodies anti-oxLDL, C reactive protein (CRP), leukocyte and neutrophils count, and the non-linear index were investigated. Interleukin (IL)-6,-8 and CRP, antibodies anti-oxLDL, TG and leukocyte and neutrophils counts were higher in periodontitis patients. The patients with periodontitis underwent periodontal treatment. Additional samples were collected after 3, 6 and 12 months after treatment. One year after the treatment, TG, IL-6,-8, CRP, Leukocyte and neutrophils counts, anti-oxLDL antibody were significantly lower. Our results confirmed that the periodontal treatment induces systemic changes in several markers the risk for atherosclerosis.

A literatura tem alertado para a presença de imagens radiopacas em radiografias panorâmicas, adjacentes à coluna cervical, indicativas de calcificações na bifurcação da artéria carótida, representando indícios da presença de ateromas. Diferentes imagens radiopacas podem ser observadas na região cervical (anatômicas e patológicas), cujas características devem ser conhecidas. Existem, no entanto, considerações a serem feitas em relação a diferentes constituições físicas entre sexos, raças, e mesmo relacionadas ao tipo físico do indivíduo, que podem produzir projeções diferenciadas nas radiografias panorâmicas. A interpretação dessas radiografias requer uma compreensão da formação das imagens, já que a radiografia panorâmica é um sistema rotacional que resulta na formação de uma zona de nitidez dentro da qual as estruturas aparecem em foco e as que estivem para fora aparecerão borradas. O objetivo do trabalho foi avaliar a contribuição das telerradiografias, nas normas lateral e frontal, na identificação e localização de calcificações em tecidos moles, quando comparado com as observadas em radiografia panorâmica. Referências radiopacas em guta percha foram posicionadas unilateralmente, em três cabeças de cadáveres, procurando manter sempre no mesmo nível da bifurcação da artéria carótida comum, em diferentes estruturas, sítios de possíveis calcificações e foram obtidas três incidências radiográficas para cada peça anatômica. Assim, a amostra deste estudo foi composta por 27 radiografias panorâmicas, 27 telerradiografias em norma lateral e 27 telerradiografias em norma frontal, totalizando 81 radiografias. Estas imagens foram avaliadas por 05 examinadores para que identificassem qual a localização mais provável da referência radiopaca e se as telerradiografias em norma lateral e frontal auxiliaram no diagnóstico diferencial das calcificações, quando observadas na radiografia panorâmica. Os resultados obtidos apontaram que as telerradiografias em norma lateral e frontal não contribuem eficazmente na identificação e localização de radiopacidades na região cervical, e que a conformação anatômica interfere na observação da presença de radiopacidade na região cervical. / The literature has warned about the presence of radiopaque images in panoramic radiographs, adjacent to the spine, indicative of calcifications in the bifurcation of the carotid artery, representing signs of the presence of atheromas. Different radiopaque images can be observed in the cervical region (anatomic and pathologic), whose characteristics should be known. There are, however, considerations to be made with regard to the different physical constitutions between sexes, races, and even related to the physical type of the individual, which may produce differentiated projections in panoramic radiographs. Interpretation of these radiographs requires an understanding of the formation of the images, since the panoramic radiograph is a rotational system that results in the formation of a zone of nitidity within which the structures appear in focus and those that are outside of it appear blurred. The aim of the study was to evaluate the contribution of lateral and frontal teleradiographs to the identification and location of calcifications in soft tissues, when compared with those observed in panoramic radiographs. Radiopaque references in gutta percha were placed unilaterally on the heads of three cadavers, endeavoring at all times to keep to the same level as the bifurcation of the common carotid artery in different structures, sites of possible calcifications, and three radiographic incidences were obtained for each anatomic part. Thus, the sample of this study was composed of 27 panoramic radiographs, 27 lateral teleradiographs and 27 frontal teleradiographs, totaling 81 radiographs. These images were evaluated by 05 examiners so that they could identify which the most probable location of the radiopaque reference would be, and whether the lateral and frontal teleradiographs were a help in the differential diagnosis of the calcifications, when observed in the panoramic radiograph. The results obtained showed that the lateral and frontal teleradiographs did not contribute efficiently to the identification and location of radiopacities in the cervical region, and that the anatomic conformation interferes in the observation of the presence of radiopacity in the cervical region.
