Presence of Helicobacter pylori in supragingival dental plaque of individuals with periodontal disease and upper gastric diseases

Background Helicobacter pylori is a Gram-negative microorganism which is able to colonize the gastric mucosa and is associated with peptic ulcer, gastric carcinoma, and gastric mucosa-associated lymphoid tissue lymphoma. Several studies have detected this bacterium in the oral cavity, suggesting it as a potential reservoir. The aim of this study was to investigate the presence of H. pylori in the oral cavity of individuals with periodontal disease and gastric diseases. Methods 115 individuals, with mean age 49.6 (±5.8) years, were divided in 4 groups: (A) with gastric diseases and periodontal disease; (B) with gastric diseases and no periodontal disease; (C) without gastric diseases and without periodontal disease, (D) without gastric diseases and with periodontal disease. Supra and subgingival plaque samples were collected from posterior teeth of the individuals with sterile paper points, and prepared for Polymerase Chain Reaction analysis. Fisher's exact test was used for detecting statistical differences between groups (p < 0.05). Results H. pylori was detected in supragingival plaque of 9/36 (25%) of group A, 1/31 (0.3%) of group B, 0 (0%) of group C and 3/36 (8.3%) of group D. No subgingival samples were positive for H. pylori. There was a statistically higher prevalence of H. pylori in groups A and D when compared to B and C (p < 0.05). Conclusion H. pylori was detected in the supragingival plaque, but not in the subgingival plaque, of individuals with periodontal disease and upper gastric diseases. There was an association between the supragingival colonization of H. pylori and oral hygiene parameters such as the presence of plaque and gingival bleeding

Segredos do coração: a escola como espaço para o olhar sensível

Nesse artigo apresentamos a experiência da construção, na escola, de um espaço para o afeto. Em tal espaço, através da atividade artística, torna-se possível trabalhar perdas, cultivar segredos, sonhos e desejos. Espaço-lugar que permite a construção de um olhar sensível para as histórias de cada um e para a memória coletiva. A dinâmica envolvida na proposta expressa uma dimensão do ensino de arte na atualidade, como espaço de atuação entre a objetividade e a subjetividade no trabalho com os alunos. Nesta sintonia, durante as aulas de arte que configuraram a experiência aqui analisada, alinhávamos histórias dos participantes com os fios da experiência estética, cruzando referências das culturas africana e indígena com a tradição das bordadeiras, que tecem a sua história de vida com fios e panos. Na composição de todos esses elementos, criamos na escola um lugar de acolhimento das individualidades, das subjetividades de cada um de nós, verdadeiros tesouros segredados
