Novas tecnologias aliadas a novos materiais vêm de encontro à filosofia de facilitar a clínica diária, diminuindo o número de passos, consequentemente diminuindo a chance de erro se utilizando menos tempo clínico para obter bons resultados. Paciente do gênero masculino,38 anos, apresentava uma restauração classe II OD deficiente no elemento 36. Foi realizado oexame clínico, radiográfico e seleção de cor. Sobre isolamento absoluto, a restauração antiga e a lesão de cárie foram removidas. Para a realização da nova restauração foi utilizado um sistema de matriz seccional e uma resina composta de baixa tensão de contração de polimerização e baixa viscosidade com a técnica bulk-fill, seguida por uma resina convencional como é preconizado.Pode-se observar que a técnica bulk-fill é bastante simples quando comparada à técnica incremental tradicional e aliada ao uso do sistema de matrizes seccionais otimizam ainda mais o dia-a-dia na clínica.
New technologies associated with new materials have been introduced to facilitate the dailyclinical procedures, reducing the number of steps, thus reducing the chance of mistakes andchair time for clinical procedures. Male patient, 38 years old, had a deficient OD class II restorationin the lower left first molar. Clinical examination, x-ray and color selection were performed.Using rubber dam isolation, the old restoration and caries were removed. For the new restorationa sectional matrix system and a low-stress flowable bulk-fill composite were used, followedby a conventional nanohybrid composite as recommended. It can be seen that the bulk-fill techniqueis quite simple compared to the traditional incremental technique and combined withthe system of sectional matrix system further optimize the restorative procedures.

PURPOSE: Bridge anticoagulation therapy is mostly utilized in patients with mechanical heart valves (MHV) receiving warfarin therapy during invasive dental procedures because of the risk of excessive bleeding related to highly vascular supporting dental structures. Bridge therapy using low molecular weight heparin may be an attractive option for invasive dental procedures; however, its safety and cost-effectiveness compared with unfractionated heparin (UFH) is uncertain. MATERIALS AND METHODS: This study investigated the safety and cost-effectiveness of enoxaparin in comparison to UFH for bridge therapy in 165 consecutive patients (57+/-11 years, 35% men) with MHV who underwent invasive dental procedures. RESULTS: This study included 75 patients treated with UFH-based bridge therapy (45%) and 90 patients treated with enoxaparin-based bridge therapy (55%). The bleeding risk of dental procedures and the incidence of clinical adverse outcomes were not significantly different between the UFH group and the enoxaparin group. However, total medical costs were significantly lower in the enoxaparin group than in the UFH group (p or =65 years) was significantly associated with an increased risk of total bleeding independent of bridging methods (odds ratio, 2.51; 95% confidence interval, 1.15-5.48; p=0.022). Enoxaparin-based bridge therapy (beta=-0.694, p<0.001) and major bleeding (beta=0.296, p=0.045) were significantly associated with the medical costs within 30 days after dental procedures. CONCLUSION: Considering the benefit of enoxaparin in cost-effectiveness, enoxaparin may be more efficient than UFH for bridge therapy in patients with MHV who required invasive dental procedures.

O objetivo do presente estudo foi comparar a frequência de respostas positivas e negativas, bem como a intensidade da dor do paciente frente à aplicação térmica em 625 dentes humanos cariados antes e após os procedimentos restauradores. A intensidade dolorosa foi medida por meio da Escala Analógica Visual representada por uma régua calibrada em milímetros de 1 a 10. Antes de fazer a restauração aplicou-se o bastão de gelo e depois o gás refrigerante, para obtenção da resposta pulpar. Após a restauração, nova aplicação dos testes e avaliação da intensidade dolorosa valendo-se da referida escala. Os dados relativos antes e após os procedimentos restauradores foram tabulados analisando-se a frequência e percentual de respostas positivas e negativas e a intensidade dolorosa em leve, moderada e intensa. Ao comparar o bastão de gelo e gás refrigerante ocorreu diferença percentual de repostas positivas e negativas com significado estatístico (p=O,ooool) o mesmo ocorrendo à intensidade da dor nos seus três níveis tanto antes como depois dos procedimentos restauradores. Concluiu-se que, o gás refrigerante comparado com o gelo, determinou maior número de frequências de respostas positivas tanto antes como depois dos procedimentos restauradores. O número de dentes com dor intensa antes dos procedimentos restauradores foi maior do que depois da restauração a aplicação do gelo como o gás refrigerante. Quanto à intensidade dolorosa moderada e leve verificou-se que antes de realizar a restauração os índices percentuais foram menores em relação à intensidade dolorosa depois dos procedimentos restauradores tanto a aplicação do gelo como o gás refrigerante.
The aim of this study was to compare the frequency of positive and negative responses and intensity of patient pain in the thermal application in 625 human caries teeth before and after the restorative procedures. Pain intensity was measured by Visual Analogue Scale represented bya calibrated rule 1-10 mm. Before making the restoration was applied the ice stick and then the refrigerant gas to obtain the pulp response. After the restoration were made the new application testing and evaluation of pain intensity availing himself of that scale. The data before and after the restorative procedures were tabulated by analyzing the frequency and percentage of positive and negative responses and pain intensity as mild, moderate and intense. By comparing the ice stick and refrigerant occurred percentage difference of positive and negative responses with statistical significance (p = 0.00001) occurring at the same intensity of pain at its three levels both before and after restorative procedures. it concluded that the refrigerant compared to the ice stick determined more positive response frequencies both before and after restoratives procedures. The number of teeth with pain before the restorative procedures was higher than after application of the restoration of ice stick as the refrigerantAs a moderate and mild pain intensity was found that before performing the restoration percentage rates were lower in relation to pain intensity after the restorative procedures both the application of ice and the refrigerant gas.

Objetivos: avaliar o grau de conversão por meio da microdureza (KHN) e espectroscopia FT-Raman (GC) de uma resina composta direta microhíbrida (Opallis-FGM) com opacidades distintas: esmalte, dentina e translúcida fotoativadas com luz halógena (OTH, 700mW/cm2) ou luz emitida por diodo (LED, 1200mW/ em']. Materiais e métodos: sessenta corpos-de-prova foram preparados através da inserção da resina composta em incremento único em matriz de teflon bipartida com orifício central cilíndrico (2mm de altura e 4mm de diâmetro) e foram divididos em seis grupos (n= 10). Para o teste de microdureza Knoop foram realizadas cinco identações no lado oposto da superfície irradiada. O grau de conversão foi mensurado através de espectroscopia FT-Raman no lado oposto da superfície irradiada (n=5). Os dados de KHN e GC foram analisados separadamente por meio da análise de variância two-way e teste de Tukey (a=0,05) e correlacionados pelo teste de Pearson-r. Resultados: independente da opacidade, o LED proporcionou um maior GC do que OTH. Para a opacidade de dentina maiores valores de KHN e GC foram observados após ativação com LED, entretanto a resina translúcida não apresentou diferenças de KHN. A opacidade de esmalte apresentou valores de GC intermediários entre as demais e KHN similar à dentina, quando ativada com LED ou com OTH. Houve uma boa correlação entre KHN e GC r=0,5671 (p=O,OOll). Conclusões: pode- se concluir que o uso do LED pode resultar em valores maiores de KHN e GC para resina composta mais opaca comparadas à fonte halógena, tal diferença não é observada na resina composta translúcida.
Objectives: to evaluate the degree of conversion by Knoop microhardness (KHN) and FT-Raman spectroscopy (DC) of one microhybrid composite resin (Opallis-FGM) with different opacities: enamel, dentin, and translucent; photo-activated by quartz-tungsten-halogen lamp (OTH; 700mW/cm2) or light emitting diode (LED; 1200mW/cm2). Materiais and Methods: sixty samples were prepared by the resin insertion in bulk in a disc-shaped mold (2.0mm-thick and 4mm in dia meter) according to 6 groups of samples (n= 10). To Knoop evaluation five indentations in the center of the opposite surfa- ce to the light irradiated surface of the specimen were performed. The DC of the side opposite to the irradiated surface of the specimens was determined bya FT-Raman spectroscopy (n=5). KHN and DC values were analyzed by two-way ANOVA and Tukey tests (a=0.05) and correlated by Pearson-r test. Results: independent of the composite resin opacity the use of LED resulted in the higher DC than OTH. To dentin opacity higher KHN and DC were observed when activated by LED, in the other hand the translucent resin did not showed differences in KHN. The enamel opacity showed intermediary results of DC amongs others and similar KHN to dentin groups activated by LED or with OTH. There was a good correlation between KHN and DC r=0.5671 (p=O.OOll). Conclusions: it can be concluded that LED use may result in higher KHN and DC to the composite resin more opaque compared to OTH, this difference may not be observed to translucent composite resin.

The aim of the present study is to investigate changes in blood pressure, pulse rate and temperature before and after periodontal surgery. The study included 127 normal healthy patients (43 males, 84 females) with age range 9 to 65 years (mean age: 26 +/- 12 years) who underwent periodontal surgery. After administration of a local anaesthetic agent (Ultracain DS) containing 0.06 mg adrenaline, the blood pressure, pulse rate, and temperature were measured. Based on the type of operation, the patients were divided into four groups. Statistically significant changes (as decreasing) in all parameters were observed (blood pressure: systolic 111.3 +/- 20.1, diastolic 67.7 +/- 13.1, pulse rate: 87.8 +/- 14.9, temperature: 36.3 +/- 0.3 ) but these changes were significantly decreased after operations (blood pressure: systolic 105.9 +/- 19. 7, diastolic 62.6 +/- 11.3, pulse rate: 84.01 +/- 13.1, temperature: 36.2 +/- 0.3). And without age group differentiation in all parameters, statistically significant decreases were found among females (p < or = 0. 05).
