Avaliação do tempo e da concentração do condicionamento com ácido fluorídrico sobre a resistência de união entre cerâmica e cimento resinoso

The aim of this study was to verify through microtensile test the influence of time and concentration of surface conditioning with hydrofluoric acid and its interference in the adhesion of dual resin cement to porcelain.We used 32 bodies of glass-ceramic lithium disilicate system IPS e.max Press LT with dimensions of 6mm thick, 8 mm in length and 8 mm in length, which will be molded to obtain composite resin blocks corresponding to blocks ceramics. Ceramic and resin blocks were divided into 16 groups (n = 4) and numbered according to the concentration of hydrofluoric acid (2.5%, 5%, 7.5% and 10%) and conditioning time (20 seconds, 40 seconds, 1 minute and 2 minutes). The blocks were cleaned in ultrasonic apparatus with distilled water and dried with compressed air, subjected to acid etching and air-jet washed with water, dried with compressed air and received application of silane agent Monobond-S, followed by adhesive Excite ( Ivoclar Vivaden). Each ceramic block was bonded to the corresponding block of resin through the resin cement Multilink Automix. The specimens were cut to obtain nine micro samples for each set of ceramic-resin with 1 mm X 1 mm X 12 mm in length, which were submitted to microtensile test. The results were analyzed with descriptive statistics and analysis of variance with significance level of 5%, revealing that there were statistically significant (p = 0.000001 <0.05). From the Tukey test can be concluded that etching with hydrofluoric acid and 2.5% for 120 seconds gave the best bond strength, however, no statistical difference between the conditioning with the same acid in the concentration of 5.0% for 20 to 40 seconds

Estudo das propriedades mecânicas da madeira plástica

This work has in its outline the analysis of the mechanical properties of the composition of plastic residues, denominated “plastic wood”, aiming at establishing technical parameters for application of this material in substitution to the natural wood. Plastic-Wood is basically, a combination of several kind of plastic, previously selected, washed, dried and without metallic particles, which are agglomerated, extruded or introduced into a mold. The manufacturer can choose different formats and colors. During this monograph it can be observed the use of several kind of plastic, their mechanical properties and the plastic-wood production process. Also are presented features and applications of natural wood, in order to better compare their uses in several applications

Vaginose Bacteriana: Identificação e quantificação de Atopobium vaginae, Leptotrichia sp e Megasphaera sp

A vaginose bacteriana (VB) é a alteração de flora vaginal mais freqüente em mulheres em idade fértil e se caracteriza pela substituição dos lactobacilos por outras espécies bacterianas. Inúmeras complicações ginecológicas e obstétricas estão associadas à VB, como a doença inflamatória pélvica, o aumento da vulnerabilidade à aquisição do HIV, a corioamnionite clínica e histológica e o baixo peso ao nascimento. Estudos recentes demonstraram que várias espécies até então raramente ou nunca isoladas em laboratório são associadas à VB. O Objetivo desse estudo foi avaliar a freqüência de isolamento de Atopobium vaginae, Leptotrichia sp. e Megasphaera sp. em gestantes com vaginose bacteriana. Foi realizado um estudo de corte transversal prospectivo. Foram incluídas no estudo 88 gestantes com diagnóstico de VB, atendidas no Centro de Saúde Escola da UNESP no período de janeiro a setembro de 2010. Durante o exame especular e utilizando-se zaragatoas estéreis, foram coletadas amostras da parede vaginal para a confecção dos esfregaços vaginais em lâminas. O exame a fresco foi utilizado para o diagnóstico de vaginite aeróbia, de acordo com os critérios descritos por Donders et al. (2002). Os esfregaços vaginais corados pelo método de Gram, foram utilizados para o diagnóstico de flora normal, intermediária e VB de acordo com os critérios de Nugent et al. (1991). Em seguida, 5 mL de solução fisiológica foi injetada com seringa estéril na parede vaginal posterior, e após homogeneização dessa solução com o auxílio de espátula, o conteúdo foi coletado. Os lavados vaginais coletados foram centrifugados e os pellets armazenados para posterior detecção de Atopobium vaginae, Leptotrichia sp. e Megasphaera sp. pela técnica de PCR em tempo real. Do total das 88 amostras de VB, 46 (52,3%) foram positivas para os 3 microrganismos pesquisados e apenas ...(Resumo completo, clicar acesso eletrônicos abaixo)

Avaliação da alteração dimensional de modelos obtidos a partir de moldagens com alginato tradicional e outro com desinfetante

The present study aims at evaluating dimensional alteration of stone casts made from impressions with a standard irreversible hydrocolloid and an antimicrobial one. For this, an alginate without disinfectant (Type II Jeltrate) and other containing chlorhexidine (Type II Avagel) were used, which rose by the same regime of treatment: without disinfection; immersion; and spraying. A 1% sodium hypochlorite solution was used for 10 minutes. To obtain the impressions, a perforated impression tray was made from a standard metal model. After molding, the molds were washed in running water for 30 seconds to simulate removal of saliva. Then, with the exception of the control group, these molds were subjected to disinfection treatment. After 10 minutes they were washed again. 60 samples poured with type V special gypsum (Durone) were obtained, that were measured 3 times in a stereomicroscope (SZX12, Olympus) to record the average of dimensional alterations. The disinfection treatment did not bring significant changes in the models obtained from both alginate tested (standard p = 0.7102; with chlorhexidine p = 0.5832). The results showed a statistically significant and additional advantage of the traditional alginate on alginate with chlorhexidine, with respect to dimensional alteration (p < 0.05).

Microhardness of the enamel exposed to whitening dentifrices

The purpose of this study is to verify the effect of three different types of dentifrices on the superficial microhardness of bovine enamel. Methods: Forty-eight 4x4mm dental fragments were polished and randomly divided into 4 groups: GI, conventional silica-based dentifrice; GII, hydrogen peroxide-based dentifrice; GIII, carbamide peroxide-based dentifrice; and GIV, immersion in artificial saliva. After polished, the specimens received five indentations of 25g static load, for 5 seconds. Subsequently, specimens from groups GI, GII and GIII were immersed in solution containing dentifrice and distilled water, in weight proportion of 1:2, for 15 minutes daily. After this period, fragments were rinsed in tap water and stored in artificial saliva at 37oC. This procedure was repeated for 21 days and then a new analysis of the microhardness was performed. Results and conclusion: The results were submitted to ANOVA and Fisher’s test at 5%. It was concluded that all samples treated with dentifrices showed hardness decrease, being most pronounced in dentifrices containing peroxide.

Ação solvente do salicilato de metila sobre resilon e guta-percha

Objective: The aim of this study was to evaluate the action of methyl salicylate in dissolving Resilon and gutta-percha. Material and method: Ten discs of Resilon, Alpha gutta-percha and ProTaper gutta-percha were prepared (10 mm diameter × 1 mm thick) and kept at 37 °C for 48 hours. Each sample was weighed in a balance of accuracy determining the initial mass. The specimens were immersed in methyl salicylate or xylene (control) for 5  minutes, rinsed in water for 30 minutes, dried and subsequently weighed in 24 hours intervals until the stabilization of weight (final mass). The solvent capacity was expressed by the difference between the final and initial mass. The data were analyzed by using ANOVA and Tukey test with significance level of 5%. Result: The results showed that the methyl salicylate was more effective on Resilon than on gutta-percha (p < 0.05). Methyl salicylate and xylene had similar solvent action on Resilon (p > 0.05). The xylene showed better performance on gutta-percha than methyl salicylate (p < 0.05). Conclusion: It was concluded that methyl salicylate did not show solvent action on gutta-percha, however it showed effectiveness in dissolution of Resilon. Thus methyl salicylate can be a possible alternative to the use of xylene during endodontic retreatment of teeth obturated with Resilon.
