Caso de Poesia (Antônio Carlos de Brito, vulgo Cacaso)

This paper deals with characteristically anti-authoritarian aspects of Antônio Carlos de Brito’s work, alias Cacaso (1944-1987). It aims to provide evidence on his peculiar poetry writing exercise, which incorporates political and aesthetic tensions into its own language, rather than just refer to them. By anchoring in a poetics of everyday life and by being engaged in a dialogue with Brazilian literary tradition, Cacaso manages image, tone and emotion in order to instantly illuminate the impasses of his generation.

Cacaso não é bem o caso do acaso

À partir de la lecture de quelques poèmes de Lero-lero, l'ensemble de l'oeuvre poétique de Cacaso, cet article interroge sur la vision que la poésie marginale n'a pas de valeur du point de vue littéraire, ayant été construite seulement par l'expressivité spontanée des événements quotidiens, se passant de l'élaboration poétique. Au contraire, on constate que les poèmes de Cacaso visent la construction d'un simulacre de spontanéité soutenu pas par une négligence formelle, mais par une dépuration du langage qui possibilite mettre sur la corde raide les valeurs dites littéraires.

Cacaso não é bem o caso do acaso

Through the reading of Lero-lero, a collection of Cacaso's poetical work, this article questions the supposition that marginal poetry has no literary value as it was created through spontaneous expression of day-to-day facts, overlooking poetical elaboration. On the contrary, Cacasós poems point towards the construction of a simulacrum of spontaneity sustained not by a formal unconcern, but by a refined language, thereby placing the so-called literary values on a tightrope. Therefore we shall examine what this might mean and its effects.

Antropofagia, dessacralização e devoração em Rilke Shake, de Angélica Freitas

This article investigates the presence of anthropophagy on Rilke shake, analyzing the opening poem “perfect teeth, listen to me,” by the concept of devouring. It discusses how the “Poesia Pau-Brasil” by Oswald de Andrade would be the milestone of a conception of poetry desacralized in Brazil in the twentieth century, retaken by marginal generation and kept alive by Angélica Freitas, with a increasingly accelerated consumption into society as a background.

Effect of the Insertion and Polymerization Technique in Composite Resin Restorations: Analysis of Marginal Gap by Atomic Force Microscopy

This in vitro study evaluated the marginal gap at the composite tooth/resin interface in class V cavities under the influence of two insertion techniques and a curing system by means of atomic force microscopy (AFM). Forty enamel and dentin cavities were prepared on the buccal surface in bovine teeth with quadratic forms measuring 2 mm X 2 mm and depth of 1.5 mm. The teeth were then divided into four groups: group A, 10 cavities were restored in one increment, light cured by halogen light; group B, 10 cavities filled with bulk filling, light cured by the light emitting diodes (LED); group C, 10 cavities were restored by the incremental technique, light cured by halogen light; group D, 10 cavities were restored by the incremental technique, light cured by the LED. The teeth underwent the polishing procedure and were analyzed by AFM for tooth/restoration interface evaluation. The data were compared between groups using the nonparametric Kruskall-Wallis and Mann-Whitney tests (p < 0.05). The results showed a statistically significant difference between groups A and B and groups A and C. It was concluded that no insertion and polymerization technique was able to completely seal the cavity.

Evaluation of marginal microleakage in Class II cavities: Effect of microhylolrid, flowable, and compactable resins

Objective: the goal of the present study was to evaluate the microleakage on the cementum/dentin and enamel surfaces in Class 11 restorations, using different kinds of resin composite (microhybrid, flowable, and compactable). Method and materials: Forty human caries-free molars were extracted and selected. Eighty Class 11 standardized cavities were made in the cervical wall at the cementoenamel junction (CEJ) and at the mesial and distal surfaces. The teeth were divided into four groups: G1 - adhesive system + microhybrid resin composite Z100; G2 - adhesive system + compactable resin composite Prodigy Condensable; G3 - adhesive system + flowable resin composite Revolution + Z1 00 resin composite; G4 - adhesive system + Revolution fluid resin + compactable resin composite Prodigy Condensable. The adhesive system used in this study was Scotchbond Multi-Purpose Plus. The specimens were thermocycled in baths of 5degreesC and 55degreesC for 1,000 cycles and immersed in 50% silver nitrate solution. The specimens then were sectioned and evaluated on degree of dye penetration. Results: the results were evaluated using the nonparametric Kruskall-Wallis test, which showed a statistically significant difference between groups G1 and G4, G2 and G4, and G3 and G4. Conclusions: None of the materials was able to eliminate the marginal microleakage at the cervical wall; the application of a low-viscosity resin composite combined with a compactable resin composite significantly decreased the microleakage.

Marginal gingiva discoloration by gray MTA: A case report

Perforation of the root canal during insertion of an intracanal post is a complication of endodontic therapy. Mineral trixoide aggregate (MTA) has been successfully used a sealer in these situations. This material has recently been formulated in white color, allowing its application in areas of esthetic concern. This is a clinical case report of a root perforation sealed with gray MTA that resulted in discoloration of the marginal gingiva. Treatment consisted of replacing gray MTA with white MTA with the aid of a dental operating microscope, producing satisfactory esthetic results.

Accuracy of Digital Images in the Detection of Marginal Micro leakage: An In Vitro Study

Purpose: To evaluate the accuracy of Image Tool Software 3.0 (ITS 3.0) to detect marginal microleakage using the stereomicroscope as the validation criterion and ITS 3.0 as the tool under study.Materials and Methods: Class V cavities were prepared at the cementoenamel junction of 61 bovine incisors, and 53 halves of them were used. Using the stereomicroscope, microleakage was classified dichotomously: presence or absence. Next, ITS 3.0 was used to obtain measurements of the microleakage, so that 0.75 was taken as the cut-off point, and values equal to or greater than 0.75 indicated its presence, while values between 0.00 and 0.75 indicated its absence. Sensitivity and specificity were calculated by point and given as 95% confidence interval (95% CI).Results: The accuracy of the ITS 3.0 was verified with a sensitivity of 0.95 (95% CI: 0.89 to 1.00) and a specificity of 0.92 (95% CI: 0.84 to 0.99).Conclusion: Digital diagnosis of marginal microleakage using ITS 3.0 was sensitive and specific.
