ABSTRACT

Objetivou-se com este estudo analisar as ações de saúde desenvolvidas por equipes de saúde da família em um município do sudeste goiano à luz da integralidade. Trata-se de pesquisa exploratória descritiva de abordagem qualitativa. A coleta de dados foi realizada por meio de entrevistas e, após uma análise de conteúdo, elegeram-se três categorias temáticas: Ações dos trabalhadores e articulação entre elas; A ESF não funciona como Estratégia Saúde da Família; Atualização das equipes de saúde da família. Os resultados demonstram a fragmentação das ações e desarticulação entre os trabalhadores, o que dificulta a integralidade. Concluiu-se, assim, que existe uma necessidade de investimentos na educação permanente em saúde, no fortalecimento do controle social, na avaliação participativa no SUS e no aprimoramento de tecnologias de gestão e cuidado.


The objective of this study was to analyze the health activities developed by the family health team (FHT) in a municipality in Southeast Goiás under the light of comprehensiveness. This exploratory descriptive study was performed using a qualitative approach. Data collection was performed by means of interviews and then submitted to content analysis. Three thematic categories were elected: Workers' activities and the connection between them; the FHT does not work as a Family Health Strategy; and An update of family health teams. Results demonstrate a fragmentation of the activities and a lack of connection between workers, which makes comprehensiveness more difficult. In conclusion, there is a need to make permanent investments in health, strengthen social control, perform participative evaluations in the national health system (SUS) and improve management and health care technologies.


Se objetivó con este estudio analizar las acciones de salud desarrolladas por equipos de salud de la familia en un municipio del sudeste de Goiânia según la óptica de la integralidad. Se trata de una investigación exploratoria, descriptiva, de abordaje cualitativo. La recolección de datos se realizó mediante entrevistas y, luego de un análisis de contenido, se eligieron tres categorías temáticas: Acciones de los trabajadores y articulación entre ellas; La ESF no funciona como Estrategia Salud de la Familia; y Actualización de los equipos de salud de la familia. Los resultados demuestran la fragmentación de las acciones y la falta de articulación entre los trabajadores, lo cual dificulta la integralidad. Se concluye en que existe necesidad de inversiones en capacitación permanente en salud, además de fortalecimiento del control social, evaluación participativa en el SUS y mejoramiento de tecnologías de gestión y cuidado.

ABSTRACT

In this survey, retrospective and prospective clinical studies dealing with cast-post-and core and fiber posts were reviewed regarding the rate of survival of restorations and the most prevalent failures. Electronic searches of the literature were performed in MEDLINE by crossing the key words: "Fiber post and clinical study", "Fiber post and clinical evaluation", "Cast post-and-core and clinical study", and "Root post and retrospective survival study". The cut-off dates were December 1990 through the end of December 2010. Review of literature showed that several interrelated biological, mechanical, and aesthetic factors are involved in the survival rate of restorative procedures in endodontically treated teeth, and post selection should fulfill and optimize these factors. Data based on long-term clinical studies are essential for the general practitioner when making clinical decisions. An adequate selection of teeth and post system must be made, and a minimal amount of existing tooth substance should be removed. A ferrule must be present for safe indication of the fiber posts. Fiber glass posts have demonstrated good survival in clinical studies, with similar performance to cast-post-and cores. Metallic posts have good clinical survival, but the associated failures are mostly irreversible, unlike what happens with the glass fiber posts.


O objetivo foi realizar revisão de estudos clínicos retrospectivos e prospectivos de pinos e núcleos metálicos e pinos de fibra em relação à taxa de sobrevivência e tipo de falhas prevalentes. A revisão de literatura foi realizada utilizando a base de dados MEDLINE com os seguintes termos para pesquisa: “Pino de fibra e estudo clínico”, “Pino de fibra e avaliação clínica”, “Pinos e núcleos metálicos e estudo clínico”, “Pinos intra-radiculares e estudo clínicos retrospectivos”. O período avaliado foi de Dezembro de 1990 até o final de Dezembro de 2010. Vários fatores biológicos, mecânicos e estéticos estão envolvidos na taxa de sobrevivência do procedimento restaurador de dentes tratados endodonticamente. A seleção do pino deve satisfazer e otimizar esses fatores. Dados com base em estudos clínicos de longo prazo são essenciais para o clínico geral na tomada de decisões. Adequada indicação na seleção do sistema de pino devem ser feitas. Adicionalmente, desgaste mínimo da estrutura dentária existente deve ser priorizado. A presença de férula deve estar presente para garantir e melhorar a previsibilidade de pinos de fibra. Pinos de fibra de vidro têm demonstrado boa sobrevivência em estudos clínicos, com desempenho semelhante aos pinos metálicos e núcleos moldados e fundidos. Retentores metálicos apresentam boa sobrevivência clínica, no entanto as falhas envolvidas são em sua maioria irreversíveis, ao contrário do que acontece com os pinos de fibra de vidro.

ABSTRACT

This study evaluate the use of bovine teeth as a substitute for human teeth on fracture strength tests of composite fixed partial dentures (Cpd), with and without fiberglass reinforcement (Fg). Eighty teeth were selected, being 40 bovine incisors, 20 human premolars and 20 molars. Bovine incisors were ground to get a platform, simulating an occlusal surface of human molar. Teeth in pairs were embedded in polystyrene resin, simulating the periodontal ligament and divided in 4 groups: B-Cpd-Fg: bovine teeth restored with Cpd with Fg; B-Cpd-NFg: bovine teeth restored with Cpd without Fg; H-Cpd-Fg: human teeth restored Cpd with Fg; and H-Cpd-NFg: human teeth restored with Cpd without Fg. The Cpd were adhesively fixed and submitted to an axial compression load at the pontic center with a crosshead speed of 0.5 mm/min until fracture. Failure modes were assessed and classified. Data were subjected to two-way ANOVA and Tukey's HSD test (?=0.05). The tooth type had no influence on fracture strength and fracture mode. The inclusion of fiberglass increased significantly the fracture strength. The failure modes were more reparable in groups with fiber-reinforcement. Bovine teeth can be used as a substitute for human teeth in these types of fracture strength tests.


Este estudo avaliou a utilização de dentes bovinos como substituto de dentes humanos em testes de resistência à fratura de próteses adesivas de resina composta (Cpd), com e sem fibra de reforço. Oitenta dentes foram selecionados sendo 40 incisivos bovinos, 20 pré-molares humanos e 20 molares. Incisivos bovinos foram desgastados para obter plataforma, simulando superfície oclusal de molares humanos. Dentes em pares foram incluídos em resina de poliestireno, simulando o ligamento periodontal. As amostras foram divididas em 4 grupos: B-Cpd-Fg, dentes bovinos restaurados com reforço de fibra de vidro, Fg; B-Cpd-NFg, dentes bovinos restaurados com Cpd sem Fg; H-Cpd-Fg, dentes humanos restaurados com Cpd Fg e H-Cpd-NFg, dentes humanos restaurados com Cpd sem Fg. O Cpd foi fixado adesivamente e submetido a carga de compressão axial no centro do pôntico com velocidade de 0,5 mm/min até a fratura. Padrões de fratura foram classificados. Os dados foram submetidos ANOVA fatorial e teste de Tukey HSD (?=0,05). O tipo de dente não teve nenhuma influência na resistência à fratura e modo de fratura. A inclusão de fibra de vidro aumentou significativamente a resistência à fratura. Os padrões de fratura foram mais reparáveis nos grupos com fibra de reforço. Os dentes bovinos podem ser usados como substituto para dentes humanos nesses tipos de testes de resistência à fratura.

ABSTRACT

This study evaluated the influence of the method and period of storage on the adhesive bond strength of indirect composite resin to bovine dentin. Ninety bovine incisors were stored in three different solutions: 0.2 percent thymol, 10 percent formalin, and 0.2 percent sodium azide, during 3 periods of storage: 7 days, 30 days and 6 months, resulting in 9 groups (n = 10). The roots were cut off and the buccal surface was ground with #600-grit silicon carbide paper. The surface was conditioned with 37 percent phosphoric acid for 15 s and a composite resin restoration (TPH Spectrum) was fixed using a one-bottle adhesive system (Adper Single Bond) and a dual-cured resinous cement (Rely X ARC) under a load of 500 g for 5 minutes. The samples were serially cut perpendicular to the bonded interface to obtain slices of 1.2 mm in thickness. Each slab was trimmed with a cylindrical diamond bur resulting in an hourglass shape with a cross-sectional area of approximately 1 mm². The microtensile bond strength (μTBS) testing was performed in a testing machine (EMIC 2000 DL) at a 0.5 mm/minute crosshead-speed until failure. After fracture, the specimens were examined under SEM to analyze the mode of fracture. μTBS Means were expressed in MPa and the data were analyzed by two-way ANOVA (3X3) and the Tukey test (α = 0.05). The storage times of 7 and 30 days produced no significant difference irrespective of the solution type. The formalin and thymol solutions, however, did have a negative influence on bond strength when the teeth were stored for 6 months.
