Abstract Aging is a growing phenomenon, both in dimension and in years of life. This qualitative study has the general objective of understanding the perception that young people have about older people, seeking to assess how stereotypes interfere in intergenerational relationships, especially the concept of ageism. The sample is made up of 9 participants, young people between 15 and 19 years old, and corresponded to the theoretical saturation criterion. The main results showed that, in the view of young people, older people are people who have the ability to carry out their tasks and are also people with experience and wisdom acquired throughout their lives. This positive view seems to be influenced by living with family members. It was also found that, despite the lack of knowledge about the concept of ageism, there is a consensus among young people that the separation of generations is a present reality in our society.

Resumo O envelhecimento é um fenómeno crescente, tanto em dimensão como em anos de vida. O presente estudo de natureza qualitativa, tem como objetivo geral entender a perceção que os jovens têm sobre as pessoas mais velhas, procurando avaliar a forma como os estereótipos interferem nas relações intergeracionais, principalmente o conceito de idadismo. A amostra é composta por 9 participantes, jovens entre os 15 e os 19 anos, e correspondeu ao critério de saturação teórica. Os principais resultados evidenciaram que, na visão dos jovens, os mais velhos são pessoas que possuem capacidades de realizar as suas tarefas e são também pessoas com experiências e sabedoria adquiridas ao longo do percurso de vida. Esta visão positiva parece ter influência devido à convivência com familiares. Constatou-se ainda que, apesar do desconhecimento do conceito de idadismo, existe um consenso entre os jovens que a separação das gerações é uma realidade presente na nossa sociedade.

Abstract Understand the origin, transport, and character of organic matter entering Antarctic fjords is essential as they are major components of the global carbon cycle and budget. Macromolecular pools of particulate organic matter, bulk organic geochemistry, major and trace elements in surface sediments from Collins Bay were analysed as source indicators. Oceanographic conditions, bathymetry (multibeam) and grain size were considered as environmental controlling factors. Sediment samples were taken with a van Veen grab, during the ANTAR XXV Peruvian expedition (February 2018), onboard the R/V “BAP Carrasco” from the Peruvian Navy. Biopolymeric composition revealed the predominance of fresh marine protein-rich organic matter in the seafloor of Collins Bay, denoting high quality food resource for marine benthic heterotrophs. Based on Igeo values (between 0 and 1) Collins Bay can be considered unpolluted with natural levels of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn. Distribution of most of these elements with a gradient of decrease from the shallow inner fjord towards the outer deepest fjord, suggest their association with the deposition of detrital material and lithogenic particles supplied by Collins Glacier frontal ablation and runoff. This first comprehensive baseline information would assist in interpreting downcore sedimentary reconstructions and future climate-induce changes.

ABSTRACT: Crown fracture is the most frequent dental traumatic injury (DTI) in permanent dentition. When there is pulp exposure, it is known as a complicated crown fracture. Currently, in these cases, it is recommended to carry out therapies that allow preserving the vitality of the pulp tissue, both in mature and immature teeth. This report describes the case of a 9-year-old patient with a complicated crown fracture in tooth 2.1, who underwent treatment with vital pulp therapy (Cvek pulpotomy), and adhesion of the dental fragment. In follow-up sessions (after 1 week, 4 months, 1 and 2 years), the tooth was asymptomatic. It was observed dentin bridge formation and the continuation of root development with apical closure, indications that the pulp tissue has remained vital. In this case, the importance of proper diagnosis and treatment is highlighted, together with the follow-up of a tooth with incomplete root development.

RESUMEN: La fractura coronaria es el traumatismo dentoalveolar (TDA) más frecuente en la dentición permanente. Cuando existe exposición pulpar, se conoce como fractura coronaria complicada (FCC). Actualmente, en estos casos, se recomienda realizar terapias que permitan preservar la vitalidad del tejido pulpar, tanto en dientes maduros como inmaduros. El presente reporte describe el caso de un paciente de 9 años con FCC en diente 2.1, donde se realizó tratamiento con terapia pulpar vital (pulpotomía de Cvek), y adhesión de fragmento dentario. En los controles posteriores al TDA (1 semana, 4 meses, 1 y 2 años) el diente estaba asintomático, se observó formación de puente dentinario y continuación de desarrollo radicular con cierre apical, indicios de que el tejido pulpar se mantuvo vital. En este caso se destaca la importancia del diagnóstico, tratamiento adecuado, junto al seguimiento de un diente con desarrollo radicular incompleto.

ABSTRACT: Cerebral palsy (CP) is a neurological disorder that affects approximately 2 out of every 1,000 live births. It is described as a group of developmental disorders of movement, balance, and posture, which cause activity limitation. Some studies have suggested that CP may increase the risk of dental trauma injuries (DTI). The objective of this study was to review the available scientific evidence on the prevalence and trends of DTI in people with CP, and to compare it with the prevalence of people without it. A systematic search was carried out in Pubmed, Scielo and Lilacs. Titles and abstracts were evaluated, excluding clinical case reports, systematic reviews, duplicate articles and/ or not relevant to the topic. Articles reporting the prevalence of DTI in people with CP were included. It was extracted information about the study type, methodology, prevalence of DTI, type of tooth, type of DTI in CP subjects and the prevalence of DTI from the control group, when available. A total of 32 articles were identified, of which 12 studies were selected and included for the systematic review and of these four were used in the meta-analysis. The prevalence of DTI in people with CP reported in these studies showed a range between 10.6-76.5 %. The upper incisors were the type of tooth most affected by DTI. Only four studies compared the DTI prevalence with a control group. The prevalence of DTI was higher in subjects with CP than in people without it (odds ratio 1.58 [95 % CI = 0.66 - 3.77]). However, this difference was not statistically significant and the included studies were highly heterogeneous.

RESUMEN: La parálisis cerebral (PC) es un trastorno neurológico que afecta aproximadamente 2 de cada 1000 nacidos vivos. Se describe como un grupo de trastornos del desarrollo del movimiento, equilibrio y postura, que causan limitación de actividad. Algunos estudios han planteado que la PC podría aumentar el riesgo de traumatismos dentoalveolares (TDA). El objetivo de este estudio fue revisar la evidencia científica disponible sobre prevalencia y tendencias de TDA en pacientes con PC, y compararla con la prevalencia de TDA en sujetos sin PC. Se realizó una búsqueda sistemática en Pubmed, Scielo y Lilacs. Se evaluaron títulos y resúmenes, excluyendo casos clínicos, revisiones sistemáticas, artículos duplicados y/o no atingentes al tema. Se incluyeron artículos que reportan prevalencia de TDA en personas con PC y se extrajo la información sobre el tipo estudio, metodología, prevalencia, tipo de diente, de TDA más frecuente en PC y datos de prevalencia de grupo control. Se identificó un total de 32 artículos, de los cuales se seleccionaron e incluyeron 12 estudios para la revisión sistemática y de ellos cuatro se utilizaron en el metaanálisis. La prevalencia de TDA en personas con PC reportada en estos estudios mostró un rango entre 10,6-76,5 %. Los incisivos superiores fueron el tipo de diente más afectado por TDA. Sólo cuatro estudios comparan con un grupo control. La prevalencia de TDA fue mayor en sujetos con PC que en sujetos sanos (odds ratio 1,58 [95 % IC= 0,66 - 3,77]). Sin embargo, esta diferencia no fue estadísticamente significativa y los estudios incluidos presentaron una alta heterogeneidad.

Abstract Objective: To analyze the prevalence and factors associated with malocclusions in preschool children. Material and Methods: A census, epidemiological study, with a cross-sectional, descriptive and analytic sample, was carried out with children aged between 4 and 6 years, matriculated in preschools in the town of Aiquara, Bahia, Brazil. Malocclusion in the deciduous dentition was determined through the application of the index proposed by WHO, with the Foster and Hamilton criteria also being incorporated. The data was tabulated in duplicate in a Microsoft Excel spreadsheet and following correction, was analyzed using the SPSS, STATA and PAST Software. In order to identify the associated factors, we opted for Multiple Poisson regression analysis and Principal Component Analysis (PCA). Results: A total of 148 children were examined and the general prevalence of malocclusions was 69.59%, with 57.5% in the group of 4-year-old, 76.92% those aged 5 years old and 72.46% among children aged 6 years old. In terms of primary canines, 66.2% were identified as class I, 25.7% as class II and 8.1% as class III. Normal overjet was 41.2%, increased overjet 34.5%, edge to edge bite 17.6% and anterior crossbite 6.8%. The normal overbite 51.4%, reduced 20.9% and deep 8.1%. Of the individuals, 20.9% had posterior crossbite. In the Poisson regression analysis and PCA, a statistical association between the malocclusions and dental caries, duration of use of pacifiers, onychophagia and thumb sucking, was identified. Conclusion: The prevalence of malocclusion in preschool children in the small town of Aiquara is high and the associated factors identified are capable of control and prevention.
