A experiência do impossível: O problema da responsabilidade política em Jacques Derrida

This is intended to approach some aspects of the articulation between knowledge and social injunctions in order to understand the problems concerned with the determination of its finality by the very discourse. By analysing the controversy aroused by the work of Jacques Derrida, it can be noticed that the subordination of the discourse autonomy to the obligation of a response is based on the necessity of considering singular reasons; to actively recognize them would be one of the conditions for a rigorous reinterpretation of the discourse nature and role in the contemporary world.

Instalación inmediata de prótesis provisionales en la reapertura de implantes

The study of techniques to reach aesthetics in the anterior region when using osseointegrated implants is of great importance. A literature review was made to compare effivciency and suitability of immediate provisionalization in re-opening of osseointegrated implants with respect to the set time (use of standardized cicatrizants and emergency profile cicatrizants). Immediate provisional denture in the phase of re-opening makes the restoration of the gingival contourn quicker when compared to the use of cicatrizants without intermediate phases required. © 2008 1995, Editorial Ciencias médicas.

Estética en prótesis removibles

Nowadays, aesthetics is very appreciated in the social context and a attractive smile is the object of desire in most of patients requiring prosthesis treatment. In case of removable prosthesis, total or partial, this feature is more significant since some or all teeth may be absents. Implants leading to a significant improvement in relation to function and comfort of removable prosthesis users, but the aesthetics of these prostheses had little attention in the current scientific literature. Thus, the aim of present article was to make a review of the literature on the aesthetic features related to rehabilitation with removable prostheses. In present study we found as significant factors for the aesthetics in removable partial and total prostheses: Selection of artificial teeth and their arrangement, characterization of acrylic resin basis and also the types and location of retainers for the removable partial prostheses. We conclude that the involvement and the aesthetic knowledge during the appropriate planning of this process is responsibility of the professional.

Importancia del diagnóstico precoz de los lipomas de células grandes en la región maxilofacial

Lipoma is a benign tumor composed of proliferation of mature fat cells interspersed by fibrous connective tissue, blood vessels and muscles, delimited by a thin capsule. Although it represents a mesenchymal neoplasm most common human body, are rare occurrences in the oral cavity. Presents clinical and histopathological variables that do not alter their prognosis. The pathogenesis is still uncertain, although some authors consider heredity and endocrine disorders as possible causes. Occurs with greater prevalence in obese people, although their metabolism is completely independent of the normal body lipid metabolism. The clinical diagnosis of oral lipoma is the view of a nodular mass, soft, asymptomatic, flat surface, without ulceration and limited growth. The continuing growth of the lesion may cause difficulty in chewing, speech, dental adaptation and change in facial aesthetics of the patient, requiring surgical excision of the lesion. The final diagnosis is by histopathological examination. Aims to present a literature review and clinical cases of a retrospective study of 61 cases of lipomas diagnosed in pathological service between 1978 and 2009, among the 10 573 reports during that same period. It emphasizes the special cases of large lipomas of the maxillofacial region, and the importance of early diagnosis of these lesions. A dental surgeon should be able to diagnose lipomas in an early stage in the maxillofacial area avoiding a massive growth of these lesions.

Laminate veneers - a review and clinical case

The laminate veneers are great choice for rehabilitation for anterior segment of the mouth. Actually, due the employment of dental cements and bonding to dentin, the uses of laminate veneers is an effective and conservative treatment, showing a high rate success rate. This paper presents a clinical case of 50 years old male, J.C.H, who have a chief complaint of an unattractive smile. After the diagnosis and planning, 10 laminate veneers were placed from the second bicuspid (15) to the second bicuspid (25). The correct indication of laminate veneers allows restorations with appropriate esthetic and patient's satisfaction with immediate effect on quality of life. © 2011 Nova Science Publishers, Inc.

Ensaio sobre como Macunai{dotless acute}ma me ajudou a falar sobre Educação Matemática

As if aesthetics were not content. But as we are faced with some other language (frequently called incorrect), our inclination is to correct it or to want to correct it: not luv, boy! But that's what we hear, not what should be. This essay is, based on aesthetics, a testimony about not being ashamed of its contribution to the field (Mathematics Education) - as a contribution and not 'only' style. The usual parametres for research papers are kept on check.

A psicologia do ego de ernst kris e seu legado para a psicanálise da arte

This article intends to discuss the importance of the ego-psychology towards the psychoanalytical interpretation of the aesthetic experience. Its focus is based on the Ernst Kris original work, therefore it intends to present certain basis of his aesthetical thinking. In this case, however, it will suggest one certain reading which emphasizes the problem of sublimation as a drive destination-and not as a defense mechanism-in within this relationship between art and psychoanalysis; hence, it brings out a phenomenon that crosses the psychoanalytical thinking since its first conception.

Música como aia da vontade: ensaio sobre a leitura wagneriana de Schopenhauer

In the year 1851, Richard Wagner had his first contact with the philosophy of Schopenhauer, a fact that was followed soon by his proclaimed and somewhat surprising conversion to schopenhauerianism. Tweny years later, his debt to Schopenhauer is reaffirmed in Beethoven, a comemorative writing in which are to be found the outlines of a philosophy of music - claimed by the composer to be based on Schopenhauer's aesthetics - that had great influence in Nietzsche's theoretical elaboration of the dionysiac, as it appears in The birth of Tragedy. My work aims primarily at investigating to what extent the musical aesthetics outlined in Beethoven is actually compatible with that presented in The world as Will and representation. The pointing out of remarkable differences between the two aesthetic conceptions gives then rise to some reflexions concerning the character of the relations between Wagner, Schopenhauer and the young Nietzsche.

Influence of different disinfecting solutions on the color change of artificial irises used in ocular prostheses

Making an artificial iris with an aesthetically acceptable color is an important aspect of ocular rehabilitation. This work evaluated the influence of different disinfecting solutions on changes to the color of artificial irises used in ocular prostheses. Fifty samples simulating ocular prostheses were produced with cobalt blue artificial irises and divided (n = 10) according to the disinfectant used: neutral soap, Opti-free, Efferdent, 1% hypochlorite, and 4% chlorhexidine. The samples were disinfected for 120 days and subjected to a color readings by spectrophotometry, using the CIE L*a*b* system, before the disinfection period (B), after 60 days of disinfectant exposure (T 1), and after 120 days of disinfectant exposure (T 2). Color differences (ΔE) were calculated for the intervals between T 1 and B (T 1B), and between T 2 and B (T 2B). The data were evaluated by analysis of variance and the Tukey Honestly Significantly Different (α = 0.05). All disinfectant groups exhibited color changes. The mean color change observed for all groups overall during T 2B (ΔE = 3.51) was significantly greater than that observed during T 1B (ΔE = 2.10). All groups exhibited greater color change for the b* values when compared to the a* and L* values. There were no significant differences between the disinfectant groups. It can be concluded that the time period of disinfection and storage significantly affected the stability of artificial iris color, independent of the disinfectant used. © 2012 Wiley Periodicals, Inc.

Patients' expectation and satisfaction with removable dental prosthesis therapy and correlation with patients' evaluation of the dentists

Objective. Considering that patients' satisfaction is one of the most important goals in conducting removable dental prosthesis (RDP) therapy and the fact that there are many factors which influence this parameter, the present study aims to evaluate the expectation before and satisfaction after therapy with RDP in patients who seek such therapy. As a secondary objective, other variables that may be associated with patient satisfaction are also evaluated, such as gender, age, Kennedy's classification of the arch supporting the RDP, the number of RDP adjustments after delivery and patients' evaluation of the dentists' conduct. Materials and methods. A sample of 44 patients who received RDP therapy were assigned visual analog scale scores for their expectation before and satisfaction after therapy regarding chewing, aesthetics, comfort and phonetics. They also completed a questionnaire concerning the dentists' conduct. Results. There was no statistically significant difference among scores concerning different genders, age, number of post-delivery settings and arch involved in the RDP. Regarding patients' evaluation of the dentists' conduct, there was a predominance of positive evaluations, but only different answers to the statement (i.e. 'The dentist I saw thoroughly explained the recommended treatment before it commenced') present statistically significant different scores for chewing (p = 0.040) and phonetics (p = 0.046). Conclusions. The average visual analog scale scores were high for both expectation prior to treatment and satisfaction after treatment; however, the scores for expectations were higher than those for satisfaction. © 2013 Informa Healthcare.

Correlation of previous experience, patient expectation and the number of post-delivery adjustments of complete dentures with patient satisfaction in a Brazilian population

A number of variables may influence the outcome of complete denture therapy. The objective of this study was to verify possible correlations between previous experience with dentures, patient expectation and the number of post-delivery adjustments with patient satisfaction after treatment. One hundred patients (mean age 61·9 ± 10·3) rated their previous experiences with complete dentures and their expectations before and satisfaction after treatment on a visual analogue scale (VAS) using scores from 0 (worst results) to 10 (best results). The number of post-delivery adjustments and other patient-related clinical variables was also noted. Patient expectation scores were higher than previous experience scores and satisfaction after treatment scores. Positive and weak correlations were found between previous chewing experiences with complete dentures, with regard to chewing expectations and comfort of use. Phonetics and comfort of use in previous experiences presented a positive correlation with expectations for chewing, aesthetics, phonetics and comfort of use. Groups of patients with different levels of education presented significant differences in expectation scores regarding comfort of use as well. A negative and weak correlation was found between phonetics satisfaction and the number of post-delivery adjustments. Patients' expectations for the therapy were higher than their satisfaction after treatment. Previous experiences with complete dentures could slightly influence patients' expectations and satisfaction, whereas lower scores for previous experience with complete dentures caused lower scores for both expectation and satisfaction. Patients' educational levels and the number of post-delivery adjustments influenced negatively the expectations about comfort of use and patient satisfaction, respectively. © 2013 John Wiley & Sons Ltd.
