Objectives: To verify the existence of difficulties throughout the course of dentistry clinical practices, identify musculoskeletal pain, and evaluate frequency and intensity of pain/discomfort (if existent) in different regions of the body, experienced by lefthanded students in comparison to right-handed students of the odontology courses of the state of Rio Grande do Norte (Northeast Brazil). Methods: A general questionnaire was applied to identify left-handed students in a population of 750 students, enrolled in clinical courses. An adaptation of the Grad-Corllet Diagram and a specific questionnaire on clinical practices were applied to the selected students.Descriptive statistics was utilized to analyze data of the specific questionnaire, and Mann-Whitney statistics, chi-square or Fisher's Exact tests (with a 5% significance level) were utilized for the Grad-Corllet Diagram, searching for an association between discomfort/pain in different body regions and manual laterality. Results: All students presented higher percentage of pain in the lumbar and neck/cervical regions. However, left-handed students presented higher values, with statistical significance levels of p = 0.041 for lower back, p = 0.002 for neck and p = 0.003 for cervical region. Conclusions: The majority of left-handed students classified "moderate" the difficulty of working with equipment designed for right-handers. There was high frequency of musculoskeletal pain/discomfort, with relevant statistical results for lefthanded students regarding intensity. It is suggested that the participating institutions evaluate the adoption of inclusion politics, re-adapt the infrastructure to include
248equipment designed for left-handers, and finally provide adequate work conditions for all students.
Objetivo: o objetivo deste estudo foi descrever o perfil epidemiológico, clínico e laboratorial dos casos de Leishmaniose Visceral (LV) coinfectados com o vírus da imunodeficiência humana (HIV) no nordeste do Brasil de 2007 a 2011. Metodologia: estudo descritivo dos casos de LV coinfectados com HIV, registrados no Sistema de Informação de Agravos de Notificação (Sinan). Resultados: dos 9.615 casos de LV, 5,08% eram coinfectados com HIV; o estado da Paraíba apresentou os maiores percentuais de coinfecção; o sexo masculino representou 81,3% desses casos, os pardos (84,2%) e a faixa etária 20 a 39 anos (56%) foram os mais acometidos; a taxa de letalidade foi de 10,6%, e o percentual de cura foi de 62%. Conclusão: É notória a magnitude da coinfecção LV-HIV no nordeste do Brasil, pois embora o perfil dos pacientes coinfectados por LV -HIV não seja diferente daqueles com LV clássica, a maior letalidade aponta para a necessidade de estruturação dos serviços de assistência ao paciente e de vigilância em saúde.
Objective: The objective this review was to identify the current range of shear bond strength values (SBS) that are clinically acceptable based on a synthesis of the studies published in 20 years that evaluated the SBS of brackets bonded to dental enamel with emitter diode light photo activators and whether damage to the enamel has been reported after the test. Methodology: A search strategy was developed for the selection of articles published from 1999 to 2019 in the PubMed/MedLine electronic database. In addition to reading the titles, keywords and summaries of the studies found, the studies were also obtained for the reading of the methodologies and identification of the inclusion and exclusion criteria. Results: The search for scientific articles resulted in 580 studies, but only 14 were selected based on the pre-established criteria. Ten presented methodological quality to be included in this integrative review, and the mean SBS found was 14,05 MPa with a standard deviation of ± 6,52 MPa (range from 7,53 to 20,57 MPa). Conclusion: In conclusion, it was observed that the range of shear bond strength values (5,9 to 7,8 MPa) and taken as a parameter by most authors until now is outdated, since higher values of SBS are feasible without, however, causing dental enamel damage after the debonding of the bracket.
Objetivo: Avaliar a qualidade de vida e o grau de satisfação de pacientes submetidos a tratamento ortodôntico-cirúrgico após cirurgia ortognática. Metodologia: Trinta pacientes orto-cirúrgicos responderam a dois questionários específicos (versão em português) - um sobre qualidade de vida (Orthognathic Quality of Life Questionnaire - OQLQ) e outro sobre grau de satisfação (Post-Surgical Patient Satisfaction Questionnaire - PSPSQ) - e responderam a um formulário contendo dados socioeconômico-educacionais e tempo pós-cirúrgico. As associações entre as variáveis independentes (idade, sexo, estado civil, escolaridade, renda familiar e tempo pós-cirúrgico) e variáveis dependentes (qualidade de vida e grau de satisfação) foram submetidas ao teste de Mann-Whitney (significância de 5%). O teste de correlação de Spearman (significância de 5%) foi aplicado para analisar a relação entre as variáveis dependentes. Resultados: O OQLQ teve média de 16.17 (±19.17) e mediana de 12, caracterizando a amostra com bom perfil de qualidade de vida. O PSPSQ obteve média de 26.6 (±1.99) e mediana de 27, evidenciando alto grau de satisfação após o tratamento cirúrgico. Houve correlação significativa entre o OQLQ x PSPSQ do tipo moderado negativo (0.40 a 0.69) e não houve correlação significativa entre as variáveis socioeconômico-educacionais e o tempo pós-cirúrgico com OQLQ e PSPSQ. Conclusão: O estudo indicou que a alta satisfação com o tratamento cirúrgico está diretamente relacionada à boa qualidade de vida apresentada após o tratamento, demonstrando a importância do tratamento orto-cirúrgico.
