ABSTRACT
The objective was to evaluate weed phytosociology and similarities between crop management systems in the Chapadões region. The experiment was conducted at in agricultural area located in the municipality of Chapadão do Sul, MS, during the 2016/17 harvest. Three crop managements strategies were used: (1) cotton/soybean/Urochloa, (2) millet/soybean/millet and (3) millet/soybean/crotalaria. A phytosociological survey of weeds was carried out during soybean cultivation and cover crops growth, in succession. The evaluation area for each management strategy was 0.5 ha. Soybean surveys were carried out in October and January, while the cover crop surveys were performed in February and May. The relative frequency (RF), relative density (RD), relative abundance (AR), and relative importance (RI) of weeds, Venn diagram, and Jaccard and Sorenson similarity indices were evaluated. The management area represented by the cotton/soybean/Urochloa rotation had fewer weed species than others. The species Cenchrus echinatus, Digitaria insularis, Digitaria sanguinalis, Eleusine indica and Commelina benghalensis had the highest phytosociological indeces among the monocotyledons. Attention is required for managing the dicotyledons Amaranthus deflexus, Conyza canadensis and Senna obtusifolia despite their low indices because of herbicide resistant cases. The highest indeces of similarity were found between managements areas 2 and 3, which did not rely on cotton cultivation prior to soybeans.

Objetivo: avaliar a correlação entre ansiedade e depressão com a presença de Disfunção Temporomandibular. Material e Métodos: participaram do estudo sessenta pacientes atendidos no Serviço ATM da Faculdade de Odontologia da Universidade Federal de Juiz de Fora, localizado na cidade de Juiz de Fora/Minas Gerais. Desses sessenta, trinta possuíam diagnósticos de disfunção temporomandibular, a partir do Research Diagnostic Criteria for Temporomandibular Disorder, e trinta não apresentavam o diagnóstico de disfunção. Todos os participantes responderam os questionários Escala Hospitalar de ansiedade e depressão e o Inventário de ansiedade de Beck. Os dados obtidos foram analisados por meio do programa Statistical Package for the Social Science 14.0 com o teste de Qui-quadrado e nível de significância de 5% (p<0,05). Resultados: houve correlação significativa entre os parâmetros gênero (p=0,024), idade média (p=0,033), presença de disfunção temporomandibular (p=0,034) e a variável ansiedade. Já para a variável depressão, houve correlação significativa para o diagnóstico de disfunção temporomandibular (p=0,029), e correlação não significativa para gênero (p=0,608) e idade média (p=0,175). Conclusão: há relação entre fatores psicológicos e psicossociais, como a ansiedade e a depressão e disfunção temporomandibular
Objective: to evaluate the correlation between anxiety and depression in the presence of temporomandibular Dysfunction. Material and Methods: sixty patients attended at the TMJ Service of the Dental School of the Federal University of Juiz de Fora, located in the city of Juiz de Fora/Minas Gerais, Brazil, participated in the study. Of these sixty, thirty had diagnoses of temporomandibular disorder from the Research Diagnostic Criteria for Temporomandibular Disorder, and thirty did not have a diagnosis of dysfunction. All participants answered the Hospital Anxiety and Depression Scale questionnaires and the Beck Anxiety Inventory. The data obtained were analyzed using the Statistical Package for the Social Science 14.0 program with the Chi-square test and a significance level of 5% (p<0.05). Results: there was a significant correlation between the parameters gender (p=0.024), mean age (p=0.033), presence of temporomandibular disorder (p=0.034) and the anxiety variable. As for the variable depression, there was a significant correlation for the diagnosis of temporomandibular disorder (p=0.029), and a non-significant correlation for gender (p=0.608) and mean age (p=0.175). Conclusion: there is a relationship between psychological and psychosocial factors, such as anxiety and depression with temporomandibular disorders

ABSTRACT This article had the objective of reporting a case of aesthetic rehabilitation with laminated facets from the 14 to the 24 teeth made with IPS E.max Ceram ceramics (Ivoclar-Vivadent), which replaced previous unsatisfactory composite resin restorations in the anterior region. The patient had agenesis of 12 and 22 teeth, making it necessary to anatomize the anterior teeth. A digital smile design was first virtually created and then followed by a diagnostic wax-up. The following was performed in a single day: periodontal surgery using the flapless technique to achieve prosthetic space; teeth preparation; an additionalsilicone impression; and multiple provisional restorations of bis-acryl composite resins were fabricated. Fourteen days later, in the second session the ceramic veneers were etched with 5% hydrofluoric acid for 20s; they received a silane application and a silane heat treatment, then lastly an ultrasonic bath. A universal adhesive was used in combination with a light curing cement.Cementation was performed immediately following an occlusal adjustment. The patient returned for a follow-up appointment another fourteen days after the luting process, in which a further occlusal adjustment was performed, and he reported complete satisfaction with the treatment.
RESUMO Este é um relato de caso de reabilitação estética anterior com facetas laminadas dos elementos 14 ao 24 confeccionadas com a cerâmica IPSE.max Ceram (Ivoclar -Vivadent), as quais substituíram facetas de resina composta insatisfatórias dos elementos 13 ao 23. Ressalta-se que o paciente possuía agenesia dos elementos 12 e 22, tornando-se necessária a reanatomização dos dentesanteriores. Inicialmente ocorreu o planejamento digital, seguido pelo enceramento diagnóstico. Foi realizado em consulta única: cirurgia periodontal pela técnica "flapless" para conquista de espaço protético; confecção dos preparos para facetas; moldagem com silicona de adição; e confecção de múltiplos provisórios em resina bisacrilica. Na consulta de cimentação, as peças foram tratadas comácido fluorídrico 5% por 20s; silanizadas com Relyxceramic primer (3M ESPE), submetidas ao tratamento térmico; e banho ultrassônico. O sistema adesivo utilizado foi o Single Bond (3M ESPE) associado ao RelyxVenner (3M ESPE). Imediatamente a cimentação foi realizado um ajuste oclusal. Após 14 dias o paciente retornou para uma nova consulta de acompanhamento, na qual foi realizada mais um ajuste oclusal, e relatou total satisfação com o tratamento realizado.
