José Veríssimo e a construção do cânone literário brasileiro: um ponto de vista estético

This essay analyses the História da literatura brasileira (1916), of José Veríssimo, that from a rupture with the romantic criticism or with the interpretation of the Scientifics method of taking as a basis a theoretical eclecticism that makes him distrust the enclosed methods and the restrict classifications. From ethnological valorization to Nationalist sentiment or from Scintificism to the support of the esthetics in the building of a Brazilian literary canon, José Veríssimo’s critical works are featured by an organicity that generates his refined criteria

Adaptação literária para televisão: uma análise de O Canto da Sereia

The Literary adaptation for television miniseries are present in the schedule grids of Brazilian television channels. We can afford that it is about a line of production of the most relevant in the two main television networks that maintain a project of teledramaturgy. The Strong presence of miniseries imposes the need to investigate the process of intersemiotic translation from the literary text to the audiovisual text on the way to reflect the esthetics of these productions in front of the constants process of tecnology mutation. In this sense the goal of this research is to analize the book adaptation O canto da sereia for television, where we identify the discursivas strategies that structure the narrativity, the themes and the figures that enable the identification with the original literary text

A comparison of microhardness of indirect composite restorative materials

The purpose of this study was to compare the microhardness of four indirect composite resins. Forty cylindrical samples were prepared according to the manufacturer s recommendations using a Teflon mold. Ten specimens were produced from each tested material, constituting four groups (n=10) as follows: G1 - Artglass; G2 - Sinfony; G3 - Solidex; G4 - Targis. Microhardness was determined by the Vickers indentation technique with a load of 300g for 10 seconds. Four indentations were made on each sample, determining the mean microhardness values for each specimen. Descriptive statistics data for the experimental conditions were: G1 - Artglass (mean ±standard deviation: 55.26 ± 1.15HVN; median: 52.6); G2 - Sinfony (31.22 ± 0.65HVN; 31.30); G3 - Solidex (52.25 ± 1.55HVN; 52.60); G4 - Targis (72.14 ± 2.82HVN; 73.30). An exploratory data analysis was performed to determine the most appropriate statistical test through: (I) Levene's for homogeneity of variances; (II) ANOVA on ranks (Kruskal-Wallis); (III) Dunn's multiple comparison test (0.05). Targis presented the highest microhardness values while Sinfony presented the lowest. Artglass and Solidex were found as intermediate materials. These results indicate that distinct mechanical properties may be observed at specific materials. The composition of each material as well as variations on polymerization methods are possibly responsibles for the difference found in microhardness. Therefore, indirect composite resin materials that guarantee both good esthetics and adequate mechanical properties may be considered as substitutes of natural teeth.

Uncommon crown-root fracture treated with adhesive tooth fragment reattachment: 7 years of follow-up

Crown-root fractures account for 5% of all fractures in permanent teeth and can involve enamel, dentin, and cementum. Depending on whether there is pulpal involvement, these problems may be classified as complicated (which are more common) or noncomplicated. The treatment depends on the level of the fracture line, root length and/or morphology, and esthetic needs. Several treatment strategies are available for esthetic and functional rehabilitation in crown-root fractures. Adhesive tooth fragment reattachment is the most conservative restorative option when the tooth fragment is available and the biological width has no or minimal violation. This article reports a case of an uncomplicated crown-root fracture in the permanent maxillary right central incisor of a young patient who received treatment with adhesive tooth fragment reattachment, preserving the anatomic characteristics of the fractured tooth after periodontal intervention. The fracture line of the fragment had an unusual shape, starting on the palatal side and extending to the buccal side subgingivally. After 7 years, the attached coronal fragment remained in position with good esthetics, as well as clinical and radiographic signs of pulpal vitality, periodontal health, and root integrity, thus indicating success.

Analysis of the peri-implant soft tissues in contact with zirconia abutments: an evidence-based literature review

The aim of this study is to evaluate through a literature review, the soft tissue response in contact with zirconia abutments, including case reports comparing prosthetics rehabilitations with zirconia and titanium abutments upto 3 years of follow-up as well as the factors that should be considered on implant's abutment selection. Metallic abutments can provide grayish color when in contact with thin soft tissues which may lead the implant prosthetic treatment to failure. In this context, the abutments of zirconia stand out because there is an excellent linking between esthetics and the health of peri-implant soft tissues. A consult of the published researches was made on the PubMed database from 2000 to September 2012. The including criteria were: literature reviews, clinical studies and case reports in English that focused on the response of the soft tissue in contact with zirconia implant abutments. The studies that were not in English and did not match the tackled issue were excluded. A total of 32 articles were found. According to the search strategy, just 16 articles were selected for this review. Three studies affirmed that zirconia abutments have an excellent soft tissue response; one study showed increased gingival recession with zirconia abutments and nine studies do not stand out any difference on biological behavior between titanium and zirconia abutments. Three studies affirmed that zirconia abutments provide natural gingival appearance, anatomic contour and greater esthetics. The use of zirconia abutments is recommended for anterior regions because of their greater optical properties and esthetic results and more studies should be performed and analyzed longitudinally regarding their biological response. The zirconia abutments have been established to be essential in order to achieve great esthetic results in cases of thin peri-implant soft tissues and in regions where the three-dimensional placement of implants is more superficial.

Dynamic UCLA for single tilted implant in an aesthetic region

The aim of this paper was to present a rehabilitation of a patient with a dynamic universal castable long abutment (UCLA) for a single tilted implant in the anterior maxillary area. A 57-year-old male patient attended the dentistry college clinic complaining of a vertical fracture of a residual root of the dental element 22. The tooth extraction was indicated for the implant installation. Due to the socket buccal wall thickness, the implant was installed with an inclination to the palate. It was done in a two-stage surgical protocol, and an external hexagon implant (3.75×11.5mm) was placed. After a six-month healing period to correct the implant position, a dynamic UCLA was set in place, rectifying the implant emergence profile at 20°. The ceramic structure fitting was performed and, after the patient's consent, the prosthesis was finalized and installed. After a follow-up period of twenty months, no complications were observed. The installation of tilted implants with a dynamic UCLA may be a viable option, faster and less invasive than bone grafts.

Em Cristo, poetas denunciam a podridão da modernidade: uma análise da obra Tempo e eternidade

This assignment aims to do a critical and interpretative review of the masterpiece Tempo e Eternidade, published by the Brazilian poets Jorge de Lima and Murilo Mendes in 1935. It is a result of a project called Restaurando a poesia em Cristo, created by many different Brazilian poets as Tristão de Ataíde, Augusto Schimdt, and others. It is worth highlighting the importance of these poems, because of the period when they were published and for the modern proposal, as the theme, which the poets denounce the bad aspects of modernity of the century through the Holly Bible, as also for the new esthetics. In the 30s, Brazil was passing through many changes; in aspects of history - the transition between the governments of Oligarchy to the New State, in governance of Getúlio Vargas; and in the literary context, it was the beginning of the second phase of Modernism, from 1930 to 1945. This period remains the consolidation of the literary movement, in terms of esthetics, since the major proposal of Modernism is freedom of the verse and, in this second phase, the search for a renovation of the language and the enlargement of the themes in poetry, such in the religious aspect or the social-political' themes. In this perspective, it aims to show the importance of the masterpiece for the history of Brazilian literature, coated as part of a turning point between the first and second phase of Modernism, also for the thematic renovation in religious poetry and esthetics, with a new proposal of esthetics. The methodology for the analyses of the poems will be through Antonio Candido's proposal, in O estudo analítico do poema, based on interpretation and comments. Therefore it intends showing through the analyses the relevance of the masterpiece written by the Brazilian poets, to the area of religious poetry and for the literary movement of that time

Segmental osteotomy for the correction of a malpositioned single implant: an 8-year follow-up

This case report is an 8-year follow-up of a malpositioned single implant, which was treated with segmental osteotomy, to confirm the treatment's characteristics, indications, and advantages. Deep buccal positioning of an endosseous implant placed in the maxillary left central incisor area did not permit acceptable prosthetic rehabilitation, despite its favorable bone insertion with no significant marginal bone loss. The surgical procedure included osteotomy and block movement performed toward the lingual and cervical position, fixed with a provisional prosthesis and miniplates and mini-implants. A connective tissue graft was necessary for esthetics optimization and was performed in a second stage. Advantages including the prevention of alveolar ridge damage, the improvement of gingival contour, and the use of an already integrated implant are presented. Clinically satisfactory hard and soft tissue stability permitted us to consider segmental surgery as a reliable alternative for malpositioned osseointegrated implants.

An alternative maneuver to treat gingival recession

This article reports a clinical case in which was applied autologous bone graft associated with subepithelial connective tis- sue graft, harvested by gingivectomy procedure with technical modifications to increase gingival graft extension, also to be used as guided tissue regeneration, to treat a single gingival recession. After 1 year and 2 months of follow-up, the cover- age of the recession was 4.0 mm, which corresponded to the gain of attached keratinized gingival tissue. An increase in the gingival tissue thickness was observed, without significant probing depth. The procedures applied to treat this case may be biologically and clinically useful to treat gingival recession.

Enxerto de tecido conjuntivo para correção da margem peri-implantar

Soft tissue recessions frequently cause esthetic disharmony and dissatisfaction. The results of coverage in peri-implant sites, in comparison with soft tissue coverage around a tooth, is less predictable. This clinical report describes the correction of an esthetic problem with a single-tooth implant-supported using a subepithelial connective tissue graft (SCTG) combined with the re-establishment of a new limit of gingival margin, and emergence crown profile. After anamnese and clinical exam it was observed an implant in the region of tooth 22 in vestibular position to alveolar ridge with a recession of 5 mm in its vestibular face. In the first cirurgical procedure the crown and the abutment were removed and a SCTG associated with a coronally positioned flap was performed in order to re-establish the limit of gingival margin. After 90 days, it was observed that the tissue in the implant site showed no adequate volume or thickness. Because of that, another SCTG was performed. The reopening procedure to install the healing cap was performed after 4 weeks. Then the prosthesis was installed. At 180 and 360 days postoperative, the implant adjacent tissue presented regular contour, color compatible with health and absence of bleeding. The patient was satisfied with the esthetic result. According to the clinical results and favorable esthetics it was possible to conclude that the use of ETC to correct an esthetic deficiency may be a feasible approach to establish new and stable peri-implant soft tissue contours.
