Prática odontológica no Programa Saúde da Família voltada para os pacientes portadores de hipertensão

O trabalho do cirurgião dentista como membro da equipe multiprofissional da Estratégia de Saúde da Família deve ser participativo nas ações de integralidade contempladas dentre os princípios do Sistema Único de Saúde. O cirurgião dentista deverá desempenhar ações promocionais e preventivas na vida das pessoas que utilizam e dependem do serviço público de saúde. Assim, é relevante destacar sua importância na abordagem clínica do paciente em crise hipertensiva em diferentes episódios da assistência odontológica. O objetivo deste estudo foi descrever o papel do CD no atendimento aos pacientes com crise hipertensiva e uso de anti-hipertensivos bem como com complicações cardiovasculares em tratamento e acompanhamento na ESF. O caminho metodológico se norteou na revisão bibliográfica narrativa tanto em artigos, livros, trabalhos de conclusões de curso de graduação, pós-graduação. Os artigos foram levantados no SciELO e na LILACS, com os descritores: Hipertensão, odontologia comunitária e Programa Saúde da Família. A prática de educação continuada em primeiros socorros pelos cirurgiões dentistas não é comum, mas é cabível destacar que a realização do curso de suporte básico de vida pode ajudar a salvar vidas em seus consultórios. Manter a calma e o equilíbrio durante os atendimentos de urgência também é um dado relevante apontado nesta pesquisa. Concluiu-se que o cirurgião dentista pode prestar primeiros socorros, como qualquer outro profissional de saúde e cabe às universidades incluir esta prática nos seus currículos, assim como a participação em palestras e a implementação de educação continuada junto aos profissionais no campo de trabalho.

Planejando atenção odontológica para crianças de até cinco anos, de uma Unidade da Estratégia Saúde da Família do município de Caratinga/MG

A cárie dentária é uma doença infecto-contagiosa e sabe-se da importância dos cuidados odontológicos precoce, ainda na primeira infância, visando o controle da saúde bucal e evitando a experiência da doença cárie nesta idade. O objetivo deste trabalho foi elaborar um plano de ação que visa diminuir a prevalência da cárie dentária em crianças até os cinco anos, através de medidas educativas e preventivas para as mesmas, seus responsáveis e/ou cuidadores adscritos em uma equipe de Estratégia de Saúde da Família do município de Caratinga. Para a fundamentação cientifica foi realizado uma revisão de literatura sobre promoção de saúde bucal na primeira infância, utilizando publicações nacionais e algumas internacionais, acessíveis na Biblioteca Virtual em Saúde (BVS) e artigos científicos disponíveis em bases de dados MEDLINE (Literatura Internacional em Ciências da Saúde), LILACS (Literatura Latino americana em Ciências da Saúde), SCIELO (ScientificElectronic Library Online) e Google acadêmico, selecionados no período de setembro de 2012 a maio de 2013, publicados a partir de 1990.Foi realizado com base no planejamento estratégico situacional e compreende as seguintes etapas: definição do problema; priorização do problema; descrição do problema priorizado; explicação do problema; identificação dos nós críticos; desenho das operações; identificação dos recursos críticos; análise de viabilidade do plano de ação; elaboração do plano operativo e gestão do plano.O plano de intervenção realizado pela ESF Anápolis I é exequível, uma vez que possui os recursos necessários para sua realização e superação dos nós críticos identificados. Mostra a necessidade de envolver no processo os cuidadores e os educadores e, também a realização de ações intersetoriais. Além disso, aprimorar o processo de trabalho da ESB.

Capacitação do agente comunitário de saúde como motivador para adesão a consulta odontológica programada

A educação e a saúde é um importante instrumento para promover a participação ativa das pessoas na conquista de sua autonomia. Trata-se de um Plano de Intervenção a partir de um estudo pautado em uma revisão da literatura com os temas o perfil e prática do ACS junto a promoção da saúde bucal. A metodologia para a realização do Plano de intervenção, após revisão da literatura, é pelo método do PES. O PES é um planejamento estratégico situacional, ou seja, é um planejamento realizado pelo método da estimativa rápida a partir da coleta de dados em registros da unidade e fontes secundárias, entrevista realizada com informantes chaves da comunidade e observação ativa da área. O Programa Saúde da Família ou PSF no Brasil, conhecido hoje como "Estratégia da Saúde da Família", por não se tratar mais apenas de um "programa", teve início, em 1994 como um dos programas propostos pelo governo federal aos municípios para implementar a atenção primária. A Estratégia de Saúde da Família propõe a mudança do modelo assistencial vigente, onde predomina o atendimento emergencial ao doente, na maioria das vezes em grandes hospitais. Estabelece que a família seja o objeto de atenção, no ambiente em que vive, permitindo uma compreensão ampliada do processo saúde/doença. Em Guará- SP foi observado pelos dados registrados no SIAB um alto número de atendimentos odontológicas de urgências por demanda espontânea e baixo número de consulta odontológica programada. A ESB do Jardim Itapema deu a devida importância a este fato, o que motivou a ESF a elaboração de um plano de ação para o enfrentamento do problema. Foi elaborado inicialmente um diagnóstico situacional da área de abrangência da ESF Jardim Itapema, de acordo com o módulo sobre Planejamento e Avaliação das Ações em Saúde do Curso de Especialização em Atenção Básica em Saúde da Família e para o embasamento científico foi realizada uma revisão literária com utilização dos seguintes descritores: "treinamento e capacitação, agente comunitário, saúde bucal" com a busca realizada na Biblioteca Virtual de Saúde (BVS-BIREME), na base de dados eletrônica (LILACS) e (SciELO), Google acadêmico e no site do Ministério da Saúde

Evaluation Of Photodynamic Therapy Using A Diode Laser And Different Photosensitizers Against Enterococcus Faecalis.

Photodynamic therapy (PDT) has been proven to be effective in disinfecting root canals. The aim of this present study was to evaluate the effects of PDT on the viability of Enterococcus faecalis using methylene blue (MB) and malachite green (MG) as photosensitizers. Solutions containing E. faecalis (ATCC 29212) were prepared and harvested by centrifugation to obtain cell suspensions, which were mixed with MB and MG. Samples were individually irradiated by the diode laser at a distance of 1mm for 30, 60, or 120 seconds. Colonyforming units (CFU) were determined for each treatment. PDT for 60 and 120 seconds with MG reduced E. faecalis viability significantly. Similar results were obtained when MB was used as photosensitizer. PDT using MB and MG have antibacterial effect against E. faecalis, showing potential to be used as an adjunctive antimicrobial procedure in endodontic therapy.

Efeito cariostático de restaurações adesivas em superfícies radiculares: estudo in vitro

Dental materials that release fluoride have been shown to be effective in caries inhibition around restorations. Adhesive materials would also be effective in caries inhibition by sealing and protecting cavity margins from acidic demineralization. This in vitro study tested the hypothesis that composite restorations with a dentin adhesive system have a caries preventive effect similar to that of an adhesive material with fluoride - glass-ionomer cement - on root surfaces. Twenty roots from extracted sound third molars were embedded in polystyrene resin and ground flat. Standardized cavities were prepared in leveled root surfaces and randomly restored with (a) Chelon-Fil (Espe) or (b) Z100/SingleBond (3M). Baseline indentations were measured at 100, 200 and 300 mum from the occlusal margins of each restoration and the surface microhardness values were obtained using a Knoop diamond indenter. A 2.0 mm wide margin around the restorations was submitted to a pH-cycling model, at 37ºC. After that, surface microhardness was measured again, as it was before. The differences between baseline and final surface microhardness were considered for statistical analysis. The median values of differences were (a): -3.8; -0.3; -1.0; and (b): 3.3; 2.5; 1.7, for the distances of 100, 200 and 300 mum, respectively. The Kruskal-Wallis test did not show statistically significant difference between 100, 200 and 300 mum distances in each tested group. There was no difference between the studied materials at the distances of 200 and 300 mum. Chelon-Fil was statistically different from Z100/SingleBond, at 100 mum (p<0.05). Under the studied conditions, the glass-ionomer cement had a higher caries preventive effect than the composite/dentin adhesive restorations.

Medo, ansiedade e controle relacionados ao tratamento odontológico

The aim of this study was to test fear, anxiety and control related to dental treatment. The subjects were 364 children with ages between 7 and 13 years. Three questionnaires with multiple choice questions were applied in groups of 10 children. The first instrument was the 15-item dental subscale from the Children’s Fear Survey Schedule9. The subjects rated their level of fear on a 5-point scale. The second survey instrument was the 20-item subscale from the State Trait Anxiety Inventory for Children16. This measure was used to capture how anxious the child was, in general. The third instrument was the Child Dental Control Assessment19. It contained 20 items to assess perceived control and 20 items to assess desired control. The results of the survey indicated that dental fear and anxiety were slightly higher for females when compared with male subjects (P < 0.05). Older children (11 to 13 years old) obtained higher fear scores than younger ones (7 to 9 years old). Concerning perceived control, the results indicate that younger children perceive more control than older ones. For desired control, the results indicate that younger children reported higher percentages than older ones. In this study, patients who had undergone anesthesia during treatment revealed higher fear scores when compared with those who had not. Dental fear etiology seems to be related to a procedure that may involve pain or lack of control.

Alteração dimensional linear de resinas para bases de próteses polimerizadas com microondas

This study examined the influence of three polymerization cycles (1: heat cure - long cycle; 2: heat cure - short cycle; and 3: microwave activation) on the linear dimensions of three denture base resins, immediately after deflasking, and 30 days after storage in distilled water at 37± 2ºC. The acrylic resins used were: Clássico, Lucitone 550 and Acron MC. The first two resins were submitted to all three polymerization cycles, and the Acron MC resin was cured by microwave activation only. The samples had three marks, and dimensions of 65 mm in length, 10 mm in width and 3 mm in thickness. Twenty-one test specimens were fabricated for each combination of resin and cure cycle, and they were submitted to three linear dimensional evaluations for two positions (A and B). The changes were evaluated using a microscope. The results indicated that all acrylic resins, regardless of the cure cycle, showed increased linear dimension after 30 days of storage in water. The composition of the acrylic resin affected the results more than the cure cycles, and the conventional acrylic resin (Lucitone 550 and Clássico) cured by microwave activation presented similar results when compared with the resin specific for microwave activation.

Rugosidade e pigmentação superficial de materiais ionoméricos

The aim of this study was to compare two methods of surface roughness analysis, perfilometry and spectrophotometry, applied to the surface of ionomeric materials (Chelon Fil, Vitremer and Dyract), submitted to different surface finishing treatments. For the perfilometric analysis, sixty specimens of each material were made and randomly separated into three experimental groups. The average surface roughness (Ra, mm) was measured on each specimen by a surface perfilometer (Mitutoyo Surftest 211). The spectrophotometric analysis consisted in quantifying the dye impregnated in the samples. The dyes used were 0.5% fuchsin and 0.5% erythrosin. Data were submitted to variance analysis (ANOVA) and t-Student test at a 0.05 significance level. There was no linear correlation between average roughness and superficial deposition of dye. Perfilometric analysis revealed that 12- and 30-bladed carbide burs caused the roughest surface of Chelon Fil, followed by Sof-Lex discs and mylar band. There were no significant differences between the specimens submitted to finishing and polishing with Sof-Lex discs and the control group (mylar band) for Vitremer, nevertheless, the highest Ra values were obtained when 12- and 30-bladed burs were used. For Dyract, there was no significant difference between the three treatments. The mean values of superficial deposition of dye for Chelon Fil, Vitremer and Dyract were: 1.7261, 1.4759, 1.3318, respectively. There were no significant differences between the restorative materials when different finishing and polishing systems were used.

Avaliação in vitro do aparelho DIAGNOdent para diagnóstico oclusal

The aim of this study was to determine the effectiveness and reliability of laser fluorescence measurements in relation to occlusal caries diagnosis. DIAGNOdent 2095 (Kavo, Biberach, Germany), which has been developed especially for caries diagnosis, was utilized. Five (5) teeth were examined in the pilot test; after that, ten (10) teeth were examined in order to calibrate both examiners. Data were obtained from 66 teeth (36 molars and 30 premolars), totalizing 144 sites identified through photographs of the occlusal surfaces. Reproducibility was evaluated in 10 teeth. The interexaminer Spearman correlation (r) was 0.89 and the intra-examiner, 0.93 and 0.97 (examiner A and B, respectively). Validation was carried out by histological examination (stereomicroscope). For the two examiners the sensitivity of the device was relatively high, varying from 0.81 to 1.00, while specificity varied according to which validation criterion was used (0.77 - 0.86: enamel lesion / 0.52 - 0.59: dentin lesion). It was concluded that DIAGNodent presented good capacity of identifying any alteration of the dental surface, nevertheless it presents the disadvantage of accomplishing many false-positive diagnosis when the validation criterion is dentin lesion.

Estudo comparativo dos métodos de estimativa da idade óssea de Greulich & Pyle e Tanner & Whitehouse

The purpose of this study was to verify whether the Greulich & Pyle (GP), Greulich & Pyle Visual (GPV) and Tanner & Whitehouse (TW) methods for estimating skeletal age could be applied in the Brazilian population, and which of these three methods could be considered more reliable when compared with the chronological age of the individuals. This study was based on one hundred and sixty volunteers (80 females and 80 males) with ages between 6 years and 10 months and 14 years and 9 months. The results showed that for the GP method, the correlations with chronological age were 0.95 for males and 0.97 for females. For the GPV method, the correlations were 0.96 and 0.97, respectively and for TW, 0.96 and 0.97. The results showed that the Greulich & Pyle, Greulich & Pyle Visual and Tanner & Whitehouse methods presented high correlation values when compared with the chronological age of the individuals. Corrective factors were established to make these methods applicable to the Brazilian population.

Efeito de baixas doses de radiação X em feridas suturadas e não suturadas - estudo experimental em ratos

The present work evaluated the effect of low doses of X-irradiation on the repairing process of sutured and nonsutured skin wounds in rats. For that, rats underwent a surgical proceedure, in which a 20 x 5-millimeter rectangular wound approximately 2-millimeter-deep was made in the dorsal region of each animal, and were divided in four groups: nonirradiated nonsutured; irradiated nonsutured ; nonirradiated sutured and irradiated sutured. The animals under irradiation were protected, during exposure, with a 2-millimeter-thick lead apron in such a way that only the incision was irradiated. Each animal was submitted to 18 seconds of exposure, undergoing a total of 7.4 rads. The evaluation of the effects of X-rays on the repairing process was carried out through microscopic observation by means of hematoxylin-eosin staining for morphological evaluation, and silver impregnation under polarized light for the observation of collagen synthesis. The results have shown that X-irradiation has caused delay in the repairing process, but it did not stop its development. The irradiated nonsutured group was considered to show the greater delay when compared with the other groups.

Termo de consentimento livre e esclarecido aos usuários de clínicas odontológicas brasileiras: aspectos éticos e legais

O consentimento do paciente antes do início de qualquer procedimento é uma condição a ser respeitada pelos profissionais da odontologia, sem nenhuma exceção. É necessário que o paciente esteja ciente de seu status de saúde, de suas necessidades específicas, do propósito de cada tratamento, conheça os planejamentos alternativos (incluindo o não tratamento), saiba do seu prognóstico, riscos, consequências, limitações e se conscientize das suas responsabilidades e as do seu cirurgião-dentista, proporcionando o sucesso do tratamento. O termo de consentimento livre e esclarecido (TCLE) visa fortalecer e esclarecer a posição do paciente, estabelecendo os direitos e deveres de ambas as partes paciente e profissional. O conhecimento integral do tratamento diminuirá a ansiedade do paciente e as complicações de tratamento, promoverá maior qualidade dos serviços odontológicos e maior satisfação do dentista e do paciente. Entretanto, no Brasil, poucos artigos são encontrados e existem alguns problemas éticos envolvendo as clínicas odontológicas, no que diz respeito a este documento de esclarecimento para o paciente. Diante disso, este trabalho tem por objetivo realizar uma revisão crítica sobre o tema abordado, demonstrando a importância do TCLE na clínica odontológica brasileira e na vida profissional dos cirurgiões-dentistas.

Comparative study of dental arch width in plaster models, photocopies and digitized images

The aim of this study was to comparatively assess dental arch width, in the canine and molar regions, by means of direct measurements from plaster models, photocopies and digitized images of the models. The sample consisted of 130 pairs of plaster models, photocopies and digitized images of the models of white patients (n = 65), both genders, with Class I and Class II Division 1 malocclusions, treated by standard Edgewise mechanics and extraction of the four first premolars. Maxillary and mandibular intercanine and intermolar widths were measured by a calibrated examiner, prior to and after orthodontic treatment, using the three modes of reproduction of the dental arches. Dispersion of the data relative to pre- and posttreatment intra-arch linear measurements (mm) was represented as box plots. The three measuring methods were compared by one-way ANOVA for repeated measurements (α = 0.05). Initial / final mean values varied as follows: 33.94 to 34.29 mm / 34.49 to 34.66 mm (maxillary intercanine width); 26.23 to 26.26 mm / 26.77 to 26.84 mm (mandibular intercanine width); 49.55 to 49.66 mm / 47.28 to 47.45 mm (maxillary intermolar width) and 43.28 to 43.41 mm / 40.29 to 40.46 mm (mandibular intermolar width). There were no statistically significant differences between mean dental arch widths estimated by the three studied methods, prior to and after orthodontic treatment. It may be concluded that photocopies and digitized images of the plaster models provided reliable reproductions of the dental arches for obtaining transversal intra-arch measurements.

Evaluation of superficial microhardness in dental enamel with different eruptive ages

This study evaluated the superficial microhardness of enamel in teeth at different posteruptive ages (before eruption in the oral cavity, 2-3 years after eruption, 4-10 years after eruption and more than 10 years after eruption). The study sample was composed of 134 specimens of human enamel. One fragment of each tooth was obtained from the flattest central portion of the crown to produce specimens with 3 x 3 mm. The enamel blocks were minimally flattened out and polished in order to obtain a flat surface parallel to the base, which is fundamental for microhardness testing. Microhardness was measured with a microhardness tester and a Knoop diamond indenter, under a static load of 25 g applied for 5 seconds. Comparison between the superficial microhardness obtained for the different groups was performed by analysis of Student's t test. The results demonstrated that superficial microhardness values have a tendency to increase over the years, with statistically significant difference only between unerupted enamel and that with more than 10 years after eruption. According to the present conditions and methodology, it was concluded that there were differences between the superficial micro-hardness of specimens at different eruptive ages, revealing an increasing mineralization. However, this difference was significant only between unerupted specimens and those with more than 10 years after eruption.

Scanning electron microscopic study of the in situ effect of salivary stimulation on erosion and abrasion in human and bovine enamel

This in situ study investigated, using scanning electron microscopy, the effect of stimulated saliva on the enamel surface of bovine and human substrates submitted to erosion followed by brushing abrasion immediately or after one hour. During 2 experimental 7-day crossover phases, 9 previously selected volunteers wore intraoral palatal devices, with 12 enamel specimens (6 human and 6 bovine). In the first phase, the volunteers immersed the device for 5 minutes in 150 ml of a cola drink, 4 times a day (8h00, 12h00, 16h00 and 20h00). Immediately after the immersions, no treatment was performed in 4 specimens (ERO), 4 other specimens were immediately brushed (0 min) using a fluoride dentifrice and the device was replaced into the mouth. After 60 min, the other 4 specimens were brushed. In the second phase, the procedures were repeated but, after the immersions, the volunteers stimulated the salivary flow rate by chewing a sugar-free gum for 30 min. Enamel superficial alterations of all specimens were then evaluated using a scanning electron microscope. Enamel prism core dissolution was seen on the surfaces submitted to erosion, while on those submitted to erosion and to abrasion (both at 0 and 60 min) a more homogeneous enamel surface was observed, probably due to the removal of the altered superficial prism layer. For all the other variables - enamel substrate and salivary stimulation -, the microscopic pattern of the enamel specimens was similar.
