ABSTRACT

ABSTRACT The aim of this study was to describe a clinical protocol for fabrication of maxillary and mandibular dentures using CAD/CAM technology. Further, digital and conventional dentures fabricated for the same patient were compared. The comparison was based on patient's satisfaction, comfort, retention, number of follow-up sessions, masticatory performance and quality of life. No laboratorial step was needed for CAD/CAM fabrication and less sessions were required up to denture insertion. Compared to the conventional dentures, digital dentures provided better satisfaction, comfort and retention and required less follow-up sessions. Both dentures presented similar results about masticatory performance and quality of life. As a conclusion, digital denture is a viable treatment alternative for edentulous patients. However, controlled and randomized clinical trials are required to reveal the real benefits of this treatment alternative compared to the conventional denture.


RESUMO O objetivo deste estudo foi descrever um protocolo clínico para a fabricação de próteses superiores e inferiores usando a tecnologia CAD/CAM. Além disso, as próteses digitais e convencionais fabricadas para o mesmo paciente foram comparadas. A comparação foi baseada na satisfação, conforto, retenção, número de sessões de acompanhamento, desempenho mastigatório e qualidade de vida do paciente. Nenhuma etapa laboratorial foi necessária para a fabricação de CAD/CAM e menos sessões foram necessárias até a inserção da prótese. Comparadas às próteses convencionais, as próteses digitais proporcionavam melhor satisfação, conforto e retenção e exigiam menos sessões de acompanhamento. Ambas as próteses apresentaram resultados semelhantes sobre desempenho mastigatório e qualidade de vida. Como conclusão, a prótese digital é uma alternativa viável para o tratamento de pacientes desdentados. No entanto, ensaios clínicos controlados e randomizados são necessários para revelar os benefícios reais dessa alternativa de tratamento em comparação com a prótese convencional.

ABSTRACT

Sodium metabisulfite is the main additive used in the prevention of melanosis in shrimp; however, it has currently been employed with great variation in concentration by producers. Thus, the aim of the present study was to determine the correlation between the concentration of the sodium metabisulfite solution and immersion time of the whole shrimp to obtain the concentration of sulfur dioxide (SO2) in the edible muscle of farmed shrimp (Litopenaeus vannamei) in accordance with the limit established by law. For this, solutions of sodium metabisulfite at different concentrations (1%, 2 %, 3 %, 4% and 5%) were prepared and samples of L. vannamei shrimp (100g) were immersed during 10, 20 or 30 minutes at temperature of 7°C. For all treatment assayed the concentration of SO2 was determined in the edible muscle of farmed shrimp (L. vannamei). The results show that for the conditions used in this study, the correlations were linear, with significant increase (P<0.05) in the SO2 concentration in the edible muscle of shrimps both increasing sodium metabisulfite concentration as increasing immersion times, suggesting the immersion of shrimps in a 3% solution for a time of 13 minutes in order to obtain SO2 concentration of 100ppm in its edible muscle in accordance with Brazilian legislation.


O metabissulfito de sódio é o principal aditivo usado na prevenção da melanose em camarão, porém, atualmente, é empregado com grande variação de suas concentrações pelos produtores. Assim, o objetivo deste estudo foi determinar a correlação entre a concentração da solução de metabissulfito de sódio e do tempo de imersão do camarão inteiro para obter a concentração final de dióxido de enxofre (SO2) no músculo comestível de camarão cultivado (Litopenaeus vannamei), de acordo com os limites estabelecidos pela legislação. Para isso, foram preparadas soluções de metabissulfito de sódio em diferentes concentrações (1%, 2%, 3%, 4% e 5%); e amostras de camarão L. vannamei (100g) foram imersas durante 10, 20 e 30 minutos à temperatura de 7ºC. Para todos os tratamentos, foram realizadas análises da concentração de SO2 no músculo comestível do camarão cultivado (L. vannamei). Os resultados demonstraram que, para as condições empregadas nesta pesquisa, as correlações encontradas foram lineares, ocorrendo um aumento significativo (P<0,05) nos teores de SO2 no músculo comestível do camarão, tanto com o aumento da concentração das soluções de metabissulfito de sódio, quanto com o aumento no tempo de imersão, sendo possível sugerir a imersão dos camarões em solução a 3% por um tempo de 13 minutos, de forma a se obter, em seu músculo comestível, a concentração de 100ppm de SO2, de acordo com o recomendado pela legislação brasileira.

ABSTRACT

New digital media (e.g., the Internet, text messaging, and social networking sites [SNS]) have dramatically altered the communication landscape, especially for youth. These communication platforms present new tools for engaging youth in sexual health promotion and risk reduction. We searched eight public databases across multiple disciplines for all peer-reviewed studies published between January 2000 and May 2011 that empirically evaluated the impact of digital media-based interventions on the sexual health knowledge, attitudes, and/or behaviors of adolescents aged 13-24 years. Of 942 abstracts, 10 met inclusion criteria. Seven studies were conducted in the United States. Eight described Web-based interventions, one used mobile phones, and one was conducted on an SNS. Two studies significantly delayed initiation of sex, and one was successful in encouraging users of an SNS to remove sex references from their public profile. Seven interventions significantly influenced psychosocial outcomes such as condom self-efficacy and abstinence attitudes, but at times the results were in directions unexpected by the study authors. Six studies increased knowledge of HIV, sexually transmitted infections, or pregnancy. This area of research is emerging and rapidly changing. More data from controlled studies with longer (>1 year) follow-up and measurement of behavioral outcomes will provide a more robust evidence base from which to judge the effectiveness of new digital media in changing adolescent sexual behavior.

ABSTRACT

OBJECTIVE: This study verified the surface microroughness of denture acrylic resins submitted to toothbrushing, chemical disinfection and thermocycling procedures. MATERIAL AND METHODS: Samples were prepared according to conventional, microwaved and boiled resins and submitted to microroughness measurements before and after procedures using a profilometer (Ra). Data were subjected to anova and Tukey's test (5%). RESULTS: Before thermocycling, a difference was found among treatments for microwaved and boiled resins, with greater values for toothbrushing and lower values for Efferdent and hypochlorite; control was intermediate. Differences among resins were observed for treatments, with higher values for boiled resin and lower values for conventional and microwaved resins. After thermocycling, differences were found for microwaved resin, with a higher value for toothbrushing and a lower value for Efferdent and hypochlorite; control was intermediate. Tooth-brushed boiled resin presented higher values and hypochlorite lower values; control and Efferdent were intermediates. Differences among resins were seen for treatments, with higher values for boiled resin and lower values for conventional and microwaved resins. Boiled resin presented differences for toothbrushing and hypochlorite, before and after thermocycling procedures were compared. CONCLUSIONS: For microwaved and boiled resins, toothbrushing and chemical disinfection promoted different levels of surface microroughness when associated or not with thermocycling.

ABSTRACT

Young Latina adults require targeted health messages to meet the unique needs of this life stage. Folic acid messages for the prevention of neural tube defects that are effective for other women might not be relevant to this group. The aim of this study was to identify barriers and motivators to folic acid consumption for this population and develop educational materials and messages that address their needs. This article presents 3 phases of formative research that formed the basis for the development of Spanish-language print materials and radio advertisements aimed at promoting folic acid consumption among young Latina adults.

ABSTRACT

Aim: This study used a photoelastic analysis to evaluate the passive fit of titanium cast laserwelding frameworks before and after spark erosion procedure. Methods: A stainless steel castwas used in order to reproduce a human mandible. Five Multi-Unit abutment analogs wereattached to this cast and 6 frameworks were produced in commercial pure titanium. The cast wasmolded and a photoelastic matrix was produced incorporating 5 dental implants with Multi-Unitabutments. All samples were subjected to a laser welding. The precision of adjustments within arange of 0.5 ìm was evaluated under microscope observation. The best fitted framework wasselected and subjected to a photoelastic analysis (Group I). The tightening of the screws was in 3predetermined sequences (1,2,3,4,5/ 5,4,3,2,1/ 3,2,4,1,5). Then the same framework wassubjected to a refinement by spark erosion technique (Group II) and evaluated by photoelasticanalysis. Results: The sequence (3,2,4,1,5) achieved better results in both groups. A largernumber of fringes were observed around the median implants in all sequences in both groups.Conclusions: The titanium cast laser welded frameworks processes associated with spark erosionprocedure improves significantly the marginal framework adaptation and is effective for its passive fit.

ABSTRACT

OBJECTIVES: The purpose of this study was to evaluate the effect of flask-closure methods, post-pressing times and acrylic resins on denture base adaptation. MATERIALS AND METHODS: The resins were flasked using a hydraulic press and closed with the traditional clamp or RS system. Conventional heat-cure resin was polymerised immediately or at 6 h post-pressing at 74 degrees C for 9 h. Rapid cycle heat-cure resin was polymerised in boiling water for 20 min. After cooling, the bases were deflasked and the sets of cast-base transversally sectioned in the regions distal to the canine, mesial to the first molar and in the posterior palatal zone. The adaptation was measured with an optical microscope (0.0005 mm) at five reference points for each section. Data were analysed using anova and Tukey's test (alpha = 0.05). RESULTS: Traditional clamp and immediate post-pressing time improved base adaptation for conventional heat-cure resin. Both post-pressing times showed most accurate base adaptation for conventional heat-cure resin when the traditional clamp was used. Immediate post-pressing time improved base adaptation for conventional heat-cure resin and the 6-h delay in time was significant for the rapid cycle heat-cure resin. CONCLUSIONS: Traditional clamp and immediate post-pressing time improved base adaptation for conventional heat-cure resin.

ABSTRACT

Each year, approximately 3000 pregnancies in the United States are affected by neural tube defects (NTDs), serious birth defects of the brain and spine. Daily periconceptional consumption of folic acid can reduce the incidence of NTDs by 50%-70%. This study was designed to understand Latina mothers' folic acid awareness, knowledge, and behaviors and to capture their reactions to advertising concepts and draft educational materials. The goal of the materials was to increase folic acid consumption through the use of a daily multivitamin. This study presents three phases of research that led to the development of Spanish language print advertisements, posters, a brochure, and radio ads that promote folic acid consumption in a manner that addresses the needs of Latina mothers.

ABSTRACT

Esse trabalho avaliou o efeito de agentes de limpeza sobre as características superficiais de materiais resilientes. Foram utilizados os materiais Luci Sof (Dentsply), Molloplast-B (Dentax) e Sofreliner (Tokuyama), e os agentes de limpeza Hipoclorito de Sódio a 0,5% (Medicinallis - Farmácia de Manipulação) e Efferdent (Warner-Lamber Co). Foram confeccionados 20 corpos de prova de cada material. Os agentes de limpeza foram utilizados da seguinte maneira: 1) Hipocloritode sódio a 0,5% (HA) a 37 ± 1 ºC, durante 20 min; 2) Peróxido Alcalino (PA) a 37 ±1 ºC, durante 15 min. Após as imersões, os corpos de prova foram lavados e imersos em água destilada a 37 ±1 ºC pelo período restante das 24 h (8x ao dia, durante 90 dias). A rugosidade superficial foi avaliada em rugosímetro Surfcorder SE 1700 (Kosaka- Laboratory Ltda),após 0 (T1), 180 (T2), 360 (T3) e 720 (T4) ciclos de higienização. Os resultados foram submetidos à ANOVA e teste de Tukey (5%). Para a imersão em HA, Luci Sof apresentou redução significativa dos valores de rugosidade superficial em T2, T3 e T4; e o material Sofreliner, em todos os tempos. Para a imersão em PA, Luci Sof apresentou redução significativa dos valores em T2, T3 e T4; Molloplast-B, redução significativa em T3; Sofreliner, aumento significativo em T4. Concluiu-se que a imersão em agentes químicos de limpeza, em geral, reduz a rugosidade superficial de reembasadores resilientes.Molloplast-B apresentou comportamento linear durante o estudo. Sofreliner, imerso em Hipoclorito, apresentou valores de rugosidade inferiores ao considerado mínimo para retenção bacteriana.

ABSTRACT

Este trabalho avaliou a alteração dimensional linear dos corpos-de-prova confeccionados a partir de matrizes retan-gulares de alumínio (65,0x12,0x3,5 mm), com 4 demarcações referenciais, sob influência das marcas de resinas acrí-licas termopolimerizáveis Clássico, Onda-Cryl e QC-20. Padrões de cera medindo 67,0x15,0x5,0mm foram incluídos em muflas metálicas ou de plástico com gesso pedra, de acordo com a técnica convencional. Após presa do gesso, os padrões de cera foram retirados e as matrizes de alumínio moldadas nos moldes de gesso reembasados com silicone. A proporção pó/líquido e preparo da resina acrílica foram efetuadas de acordo com as recomendações dos fabricantes, sendo a prensagem da mufla metálica feita com auxílio do dispositvo RS de contensão. Após a polimerização em água aquecida a 74ºC por 9 horas, água em ebulição por 20 minutos ou por energia de microondas a 900 W por 10 minutos, os corpos-de-prova foram removidos das muflas após esfriamento até a temperatura ambiente e submetidos ao processo de acabamento convencional. As distâncias entre os pontos referenciais A-B, C-D, A-C e B-D foram mensuradas antes e após a desinfecção em microondas (650W por 3 minutos). A avaliação dimensional linear das distâncias foi efetuada com microscópio óptico comparador Olympus, com precisão de 0,0005 mm, por um mesmo operador. Os resultados obtidos submetidos à análise de variância e ao teste de Tukey em nível de 5% de significância mostraram que a desin-fecção por microondas não alterou as dimensões originais dos corpos-de-prova.

ABSTRACT

A doença periodontal é caracterizado por um processo inflamatório nos tecidos de proteção e sustentação do periodonto, com características infecciosas. A maioria das variedades da doença periodontal é atribuída aos distúrbios hiperégicos associados à placa bacteriana. O processo inflamatório é a resposta do hospedeiro frente aos grupos de bactérias presentes na cavidade bucal, colonizando a superfície dos dentes. Essa resposta podem ser avaliadas por meio de análise do sulco gengival, saliva e soro. A determinação do diagnóstico, muitas vezes, não é um problema difícil, particularmente quando a patologia envolve doença crônica dentária ou peridontal reconhecível à inspeção. Entretanto, em algumas situações os limites entre doença local e sistêmica são imprecisos e para o diagnóstico correto, é necesária a avaliação completa do paciente. Em determinadas ocasiões a história média do paciente, assim como seu exame físico, justifica o pedido de testes laboratóriais para confirmar o diagnóstico ou para descobrir achados incidentais paralelos à queixa principal. Dependendo do conhecimento anterior e da experiência do dentista em interpretar estes testes, poderá indicar diretamente um laboratório clínico ou um clínico geral para exames apropriados, testes e opiniões. Exames complementares, como o próprio nome mostra, são exames subsidiários que complementam os achados clínicos. Deve-se lembrar que estes exames estão sempre vinculados aos achados clínicos
