Helicobacter pylori em boca: epidemiologia e associação com doenças bucais

The association of Helicobacter pylori with different gastric diseases has been continuously discussed in the literature, whereas the last 20 years a large body of publications was intended to characterize the ecological niches and habitats of this pathogen being the mouth a possible habitat for that rod. The present study aimed to discuss the occurrence of this organism as part of the supplemental or transient microbiota of the mouth. Thus, an extensive review of literature covering the period 1990-2014 was carried out with different databases, yielding 5024 articles discussing transmission and occurrence of H. pylori, in English or Portuguese. Articles were selected according to the inclusion and exclusion criteria and data were tabulated and analyzed. Despite the significant heterogeneity of the literature, it was found this microaerophilic has a worldwide distribution, even in the mouth, which behaves as a reservoir for gastric reinfection. The role of oral hygiene and periodontal disease in the distribution of this microorganism remains unclear, but most studies support the hypothesis that oral biofilms and inflammation of periodontium may facilitate the installation of this pathogen in the mouth. Studies suggest that this microorganism could collaborate as a predisposing factor for oral cancer.

Aggregatibacter actinomycetemcomitans em pacientes com síndrome de down: influência da condição periodontal e higiene bucal

Patients with Down syndrome have varying degrees of mental retardation, physical and motor, and apparently are more susceptible to infectious diseases. Thus, the present study aimed to evaluate the occurrence of Aggregatibacter actinomycetemcomitans in saliva and subgingival biofilms and above of children and adolescents with Down syndrome and analyze the influence of diet, socioeconomic and cultural factors and periodontal condition. After assessing the socio-economic and behavioral, were collected clinical specimens, which were transported to the laboratory of Microbiology and Immunology FOA-UNESP for detection of microorganisms by molecular method and periodontal conditions were evaluated according to the Periodontal Screening Index and Recording. The control group consisted of individuals without the syndrome. The results were analyzed by chi-square test for proportion analysis of variables with three or more categories, or the Mann-Whitney test. The data analysis of this study showed that the occurrence of A. actinomycetemcomitans ranged from 0.0% to 25.0%, both in the group of patients with Down syndrome, as for the control group and this was not affected by socioeconomic characteristics of the target population, either by oral hygiene standards

Fatores envolvidos no comportamento em higiene bucal e hábitos alimentares de crianças: revisão de literatura

The family is primarily responsible for shaping behavior in oral hygiene and nutrition of children, and cultural and psychosocial factors can influence this process. Thus, we carried out this study with the aim of presenting evidence from the literature on the subject. We reviewed the databases Bireme, Pubmed and Medline without restriction of year of publication. Used as descriptors "education," "care," "behavior," "oral health" and "food habits". We emphasize the responsibility of the family practices, values and beliefs of oral health and nutrition as well as the importance of shared care between family and professionals.

Biofilmes orais como um possível fator de risco ao câncer bucal

Introduction: much studies regarding risk factors associated with oral cancer. Factors such as smoking and alcohol and solar radiation are well established, but others, such as bacterial influence in the development or progression of a tumor still remain unexplained. Interest in the possible relationship between bacteria and different stages of cancer development has increased since the classification of H. pylori by the WHO as a definite carcinogen. Subsequently, links between infection and the onset of cancer in various sites in the body were discovered. Review of literature: this literature review attempts to show the influence of poor oral hygiene, with consequent bacterial accumulation as a possible important risk factor for the initiation and development of mouth cancer, and correlate the possible mechanisms by which bacteria can initiate or promote carcinogenesis. Conclusion: there is much evidence that bacteria in the oral cavity and periodontopathic are present in tumor tissue, however, still can not affirm that these bacteria initiate or promote carcinogenesis.

Oral health education in schools: promoting health agents

Purpose: The aim of this study was to verify the influence of preschool children participating in an oral health education programme on daily health practices of their families, through parent's perception. Methods: A sample of 119 parents of 5- to 6-year-old preschool children were selected. Data were collected using a structured open-closed questionnaire, self-administered. The questions focused on parents' knowledge about activities of oral health education conducted in school, the importance given by them to these activities, learning from their offspring and the presence of habit change at home. Results: In total, 63 (52.9%) parents agreed to participate. Ninety-eight per cent knew about educative and preventive activities developed at school and all of them affirmed that these activities were important, mainly because of knowledge, motivation and improvement in children's health. Ninety and half per cent of parents reported that they learned something about oral health from their children and, among these, almost half (47.8%) cited toothbrushing as the indicator for better learning. Besides this, 87.3% of participants revealed the change in oral health habits of their family members. Conclusion: Preschool children were able to transmit knowledge acquired at school to their parents that included change in oral health routine of their family members.
