Clinical approaches and removal of cast metallic posts for their replacement by the fiberglass posts: a concise systematic review

Introduction: A successful placement of an intraradicular post needs a good endodontic treatment. Consideration should also be given to the possibility of its future removal. Authors have shown that approximately 10% of cases of teeth indicated for endodontic retreatment require removal of intraradicular posts. Objective: To carry out a concise systematic review to analyze the reasons for replacing intraradicular posts, the most effective and used techniques for removing the metallic post, the manufacture of the fiberglass post, and the difference between the two types of posts. Methods: The present study followed a systematic review model, following the rules of systematic review – PRISMA. The search strategy was performed in the PubMed, Cochrane Library, Web of Science and Scopus, and Google Scholar databases. Results and Conclusion: A total of 112 articles were found. A total of 56 articles were fully evaluated and 18 were included in this study. Based on the objective and results found in the present study, the review demonstrated the main advantages and disadvantages of the clinical performance of cast metal posts and fiberglass posts, as well as the reason for switching from metal to fiberglass posts. Despite the wear caused by endodontic treatment, it is important to check the remaining dentin to choose the best retainer, observing the amount of this remaining structure, as it directly influences the selection of the post. Regarding the removal of the metallic pin, wear, ultrasound, and seizure/removal with some traction device are used. The replacement of the metallic post can opt for fiberglass posts because they have a greater advantage compared to the metallic post, mainly for aesthetics, the manufacturing technique is more agile, they do not generate risks of root fracture and if, for any eventuality, it needs to be removed. to portray the channel, the technique is smooth and easy

Study On The Introgression Of Beef Breeds In Canchim Cattle Using Single Nucleotide Polymorphism Markers

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The aim of this study was to evaluate the level of introgression of breeds in the Canchim (CA: 62.5% Charolais-37.5% Zebu) and MA genetic group (MA: 65.6% Charolais-34.4% Zebu) cattle using genomic information on Charolais (CH), Nelore (NE), and Indubrasil (IB) breeds. The number of animals used was 395 (CA and MA), 763 (NE), 338 (CH), and 37 (IB). The Bovine 50SNP BeadChip from Illumina panel was used to estimate the levels of introgression of breeds considering the Maximum likelihood, Bayesian, and Single Regression method. After genotype quality control, 32,308 SNPs were considered in the analysis. Furthermore, three thresholds to prune out SNPs in linkage disequilibrium higher than 0.10, 0.05, and 0.01 were considered, resulting in 15,286, 7,652, and 1,582 SNPs, respectively. For k = 2, the proportion of taurine and indicine varied from the expected proportion based on pedigree for all methods studied. For k = 3, the Regression method was able to differentiate the animals in three main clusters assigned to each purebred breed, showing more reasonable according to its biological viewpoint. Analyzing the data considering k = 2 seems to be more appropriate for Canchim-MA animals due to its biological interpretation. The usage of 32,308 SNPs in the analyses resulted in similar findings between the estimated and expected breed proportions. Using the Regression approach, a contribution of Indubrasil was observed in Canchim-MA when k = 3 was considered. Genetic parameter estimation could account for this breed composition information as a source of variation in order to improve the accuracy of genetic models. Our findings may help assemble appropriate reference populations for genomic prediction for Canchim-MA in order to improve prediction accuracy. Using the information on the level of introgression in each individual could also be useful in breeding or crossing design to improve individual heterosis in crossbred cattle. © 2017 Buzanskas et al.

Bolsa Família e (in)segurança alimentar em município mineiro. Estudo com crianças até sete anos

O Programa Bolsa Família tem sido objeto de estudos que mostram o impacto na redução da extrema pobreza e na redução da insegurança alimentar e nutricional (IAN). Objetivo: investigar a prevalência de IAN e fatores associados entre famílias com crianças menores de sete anos participantes do Programa Bolsa Família, residentes em um município do sul do estado de Minas Gerais. Métodos: Estudo transversal quantitativo realizado com 145 famílias e 206 crianças menores de sete anos. Resultados: A prevalência de IAN foi de 77,9% e de insegurança grave de 15,9%. A associação entre INF e renda familiar (p = 0,024), alimentação após o benefício (p = 0,006), consumo de feijão (p = 0,016) e salgadinhos (p = 0,006) foi encontrada entre crianças de dois anos. a sete anos. Além disso, a anemia ferropriva foi associada à introdução de biscoito recheado (p = 0,023), salgadinho de pacote (p = 0,044) e queijo petit suisse (p = 0,014) antes dos dois anos. Conclusão: Espera-se, portanto, que esta pesquisa contribua para a geração de evidências científicas que serão utilizadas na tomada de decisão para melhorar a eficiência da gestão por meio da redefinição de prioridades e qualificação dos profissionais envolvidos no programa

Development of mouthwash with Rosmarinus officinalis extract

Rosmarinus officinalis, which belongs to the Lamiaceaefamily, is a species of medicinal flora with therapeutic properties. In order to exploit the benefits of these properties, a mouthwash formulation was developed, with careful selection of raw materials to meet pharmacotechnical requirements. Extracts of the plant were incorporated into a mouthwash, which was shown to have inhibitory action in vitro against the micro-organisms commonly found in periodontics. Controls for assessing the quality of the drugs were carried out, quantifying phenols and flavonoids as chemical markers. Mouthwash solutions were formulated containing 0.1, 5 and 10% ethanol extract of R. officinalis; and 0.05, 5 and 10% of the hexane fraction of R. officinalis. In order to evaluate synergism, ethanol extract and hexane fraction were also added to formulations containing 0.05% sodium fluoride and 0.12% chlorhexidine digluconate. These formulations were assessed for inhibitory effect against the specific microorganisms involved in the process of bacterial plaque formation, S. mutans(ATCC25175) and C. albicans(ATCC 10231), frequently found in cases of oral infections. The agar diffusion method was used to evaluate the inhibitory activity of extracts and formulations. All mouthwash solutions displayed inhibitory activity having higher sensitivity to S. mutansfor the 5% ethanol extract+0.05% sodium fluoride, and greater sensitivity to C. albicansfor the 10% hexane fraction. Results were characterized by the appearance of a growth inhibition halo, justifying the utilization and association of extracts of R. officinalis

Vigilância alimentar e nutricional: estudo com pré-escolares e escolares participantes do Programa Bolsa Família

describir la situación de [in]seguridad alimentaria y nutricional de los preescolares y escolares participantes en el Programa Bolsa Família. Método: estudio transversal con familias de niños preescolares y escolares. Se aplicaron los cuestionarios de caracterización socioeconómica, de consumo de alimentos y la Escala Brasileña de Inseguridad Alimentaria. La evaluación antropométrica y alimentaria se realizó siguiendo los protocolos del Sistema de Vigilancia Alimentaria y Nutricional. Para el análisis estadístico, se realizó la prueba de chi-cuadrado con un nivel de significación del 5%. Resultados: Se consideraron 144 familias y 163 niños. La prevalencia de la inseguridad alimentaria fue del 74,3% y el 29,4% de los niños tenían sobrepeso. Se observó un elevado consumo de alimentos ultraprocesados, especialmente de bebidas azucaradas (80,4%). Se identificó una asociación estadísticamente significativa entre el uso de dispositivos electrónicos y el consumo de golosinas. Conclusión: para ampliar los efectos positivos del Programa Bolsa Família es importante la actuación intersectorial con vistas al fortalecimiento de los programas de seguridad alimentaria y de las acciones reguladoras en la alimentación
