A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals
Rodrigues,Evaldo Almeida; Silva,Sílvio José Albergaria da;
International Journal of Morphology , 2009, DOI: 10.4067/S0717-95022009000300030
Abstract: success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. the internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. this case report describes an endodontic retreatment of a maxillary central incisor with two canal systems.
A Case of Unusual Anatomy: Maxillary Central Incisor with Two Root Canals Un Caso de Anatomía Inusual: Incisivo Central Superior con Dos Canales Radiculares

International Journal of Morphology , 2009,
Abstract: Success in root canal treatment is achieved after thorough cleaning and shaping followed by complete obturation of the canal system. Therefore, endodontic therapy requires specific and complete knowledge of the internal and external dental anatomy, and its variations in presentation. Such treatment may be performed in root canal systems that do not comply with the normal anatomical features described in standard textbooks. The internal anatomy of the maxillary central incisor is well known and usually presents one root canal system. This case report describes an endodontic retreatment of a maxillary central incisor with two canal systems. El éxito de los tratamientos de endodoncia sólo puede conseguirse mediante una completa asepsia, el modelado y la obturación del canal radicular. Por ello, los tratamientos de endodoncia requieren de un completo y detallado conocimiento de la anatomía interna y externa de los canales radiculares y de sus variantes. Este tipo de tratamiento puede realizarse en canales radiculares que no coincidan con las características anatómicas normales descritas como patrón por la literatura. La anatomía interna de los incisivos centrales superiores es bien conocida, presentando normalmente un canal radicular único. En este relato se describen los tratamientos endodóncicos de incisivo central superior con dos canales radiculares.

RGO : Revista Gaúcha de Odontologia , 2009,
Abstract: Objective: The aim of this study was to assess the coronal leakage of three temporary cements in endodontics: Bioplic (Biodinamica, Londrina, Brazil), IRM (Dentsply, Petrópolis, Brazil) and Coltosol (Vigodent, Bonsucesso, Brazil). Methods: Forty human pre-molars were divided into four groups: I (Bioplic + adhesive system), II (Bioplic , Biodinamica, Londrina, Brasil), III (IRM , Dentsply, Petrópolis, Brasil), and IV (Coltosol , Vigodent, Bonsucesso, Brasil). The teeth were immersed in 1% Rodamine and kept at 37°C for 24h. They were then thermal cycled for seven days. Temperatures ranged between 5, 37 and 50°C. After longitudinal sectioning the leakage was measured in mm and statistical analysis was performed using the ANOVA and Tukey tests with a level of significance of 5%.Results: In the group in which Bioplic was used with adhesive, a lower level of leakage was detected (0.37 ± 0.24). There was significant difference (p<0.05) between groups I and III, I and IV, II and III. Conclusion: It was concluded that all the tested material showed coronal leakage and that the use of the (Bioplic Biodinamica, Londrina, Brasil)plus adhesive system showed the lowest level of leakage.
Endodontic diagnosis: evaluation between clinical and histological findings

RGO : Revista Gaúcha de Odontologia , 2008,
Abstract: Objective: In this study, the aim was to analyze the histologic alterations in thirty dental pulps and correlate them with the clinical findings to verify agreement between the clinical and histopathologic diagnosis and contribute to knowledge about endodontic diagnosis. Methods: Using the methodology of Oliveira4, the pulpal conditions were clinically classified as normal, reversible pulpitis, pulpitis at the stage of transition, irreversible pulpitis and necrosis. Results: Lack of correlation was observed between the clinical and histopathologic diagnoses in the cases classified as reversible and at the stage of transition, which histologically consisted of irreversible lesions or degenerative alterations. All the cases clinically classified as irreversible corresponded to the histologic diagnoses. Conclusion: It was concluded that the correlation between clinical and histopathologic diagnosis of dental pulp was shown to be controversial, even though the semiotechnique used had been imperative for guidance about the irreversibility of pulpal lesion.
Modernidade/pós-modernidade: tens?es e repercuss?es na produ??o de conhecimento em educa??o
Gallo, Sílvio;
Educa??o e Pesquisa , 2006, DOI: 10.1590/S1517-97022006000300009
Abstract: the article discusses the repercussions that the debate around the overcoming of modernity and the supposed coming of postmodernity has brought to education as a field of knowledge, and more particularly to the research in this field. a critical discussion is made of the thesis that we live in postmodernity, placing emphasis on this statement in the sphere of social thinking, especially for understanding that such expression does not have the strength and intensity of a philosophical concept, resulting devoid of meaning. it is stressed that of the first uses of that expression in the field of philosophy, by lyotard, was as an adjective, and not as a noun, which is significantly different. moving beyond the debate about the end of modernity or otherwise, the notion of hypermodernity proposed by lipovetsky is adopted as a way of characterizing the contemporary world and trying to understand its implications. notwithstanding that, the author recognizes the important contributions of the thesis that affirms postmodernity, especially in its epistemological and political aspects, in so far as it represents a shift of the focus of analysis. the text characterizes the current debate as the tension between two images of the thought that are not at all new, but that have gained special attention in contemporaneity, defending that we must accept this tension in what it brings in terms of a creative possibility, without paralyzing the thought.
A Institui??o total como agência de produ??o de subjetividade na sociedade disciplinar
Benelli, Sílvio José;
Estudos de Psicologia (Campinas) , 2004, DOI: 10.1590/S0103-166X2004000300008
Abstract: goffman's insights about foucault' s analyses can provide a considerable achievement about the subjectivity production processes knowledge in the contemporary society and, mainly at total institutions context, where they are so present. we consider that goffman's institutional analyses is between the macro (molar) and micro spheres of the phenomenon, that happen in closed institutions. he analyzes the non-discoursive practices, and subtlety articulates them, as the daily, apparently insignificant and bizarre "details" from institutional context makes us to realize the intra-institutional relations of microphysics plan, dipping into different strategies in which power itself branches, circulates, dominates and produces knowledges and subjects. we might say that goffman has already introduced the idea of power as a dynamical relation of strategies always achieved at all parts and places. foucault, reveals us how possible are disciplinary institutions and their reasons for emerging. they both are outstanding references to the institutional analyses.
A cultura psicológica no mercado de bensde saúde mental contemporaneo
Benelli, Sílvio José;
Estudos de Psicologia (Campinas) , 2009, DOI: 10.1590/S0103-166X2009000400012
Abstract: we studied the hypothesis of psychological culture proposed by castel, 1987, by seeking to understand the current transformations in the social field and its occurrence in the areas of mental health (psychiatry, psychoanalysis, psychology). the emergence of a new psychological cluster devoted to developing and improving the potential of the human being would aim towards the infinite programming of the human being, in the transition from a disciplinary society to one of control. with this perspective, psychology as a profession would be overcoming treatment and prevention, being redirected towards creating a relational sociability: clinical philosophy could be considered a therapeutic mode for normal people, and enneagram and neuro-linguistic programming as psychotherapeutic systems seeking to guide the human being towards global self-development. we decoded their strategic function, while they were situated in the broader context of the current form of risk management in the administration of problematic populations.

Moreira, Sílvio;
Bragantia , 1941, DOI: 10.1590/S0006-87051941000800001
Abstract: 1 - the present paper deals with the first results of an extensive study on the relations between stock and scion in citrus, in progress at the experiment station of limeira, of the instituto agron?mico of campinas, s?o paulo, brazil, since 1933. 2 - all the scions used belong to three commercial varieties : baianinha (orange, derived from "washington navel"), pera (orange, similar to valencia) and pomelo (grape-fruit "marsh-seedless") were collected in each case from one individual of each type. 3 - the following 12 stock were studied : laranja azeda (sour orange) laranja agro-doce (bitter sweet orange) laranja caipira (sweet orange) laranja lima (sweet orange) tangerina cravo (tangerine) lim?o cravo (rangpur lime) lim?o rugoso (rough lemon) lim?o ponderosa (ponderosa lemon) lima da pérsia (sweet lime) pomelo (grape-fruit triumph) cidra (citron) trifoliata (poncirus trifoliata). all plants obtained came from seeds of one tree of each type, from unprotected flowers however. 4 - data referring to the number of seeds per fruit, germination, polyembriony and classification according to size are given (quadro i). the mean height of the plants obtained after 6 months and 2 years nursery are to be found in quadro ii. 5 - twelve hundred individuals of each root stock were selected according to their uniform development, in accordance with webber (25) and on 40 of each buds of the three scions were grafted. as measure of the development the circumference of the stock at a height of 20 cm and that of the scion at a height of 40 cm were used (quadros iv to ix). 6 - an analysis of variance "between" and "within" root stocks (quadro vi) showed in all cases a significant high variation "between" stock. in all cases, the scions were thinner than the stocks (quadro ix), the indices scion-stock varying from ca. 0,5 to 0,8. the respective means are to be found in quadro iv and v. 7 - there is also a consistent and significant difference between scions as shown by the values in quadr

Psicologia em Estudo , 2009, DOI: 10.1590/S1413-73722009000100020
Abstract: we sought to execute a psychosocial analysis of a theological catholic seminary where live 50 seminarians in boarding system, at the final stage of formation to priesthood; once ordained, they will be settled in relevant positions that comprise in the coordination of large parish communities. applying a theoretical tool of institutional analysis, we mapped institutional subjectivityoperators from the pedagogical device in the seminary. we show data related to participative observation obtained in research field. besides the operators present in the official and institutional discourse, we found out that the seminary contrives in daily practice other procedures, which may be designated as totalitarian and disciplinary, producing a priest with clerical profile.
Avalia??o entre ?pares? na ciência e na academia: aspectos clandestinos de um julgamento nem sempre científico, acadêmico ou ?de avalia??o?
Botomé, Sílvio Paulo;
Psicologia USP , 2011, DOI: 10.1590/S0103-65642011005000013
Abstract: the assessment of academic work cannot be reduced to the measures. but there is an extensive “naturalization” of procedures that are not driven every respect constituting this “evaluation”. one aspect of this “naturalization has been slow and subtle substitution of debate and criticism of academic studies for its simple display, publication or presentation with examination more administrative than academic. the “peer reviews” has been a requirement with problems. they include the anonymity of the appraiser and it allows many “deviations” for an assessment of political, ideological or even personal. the tendency toward hegemony of groups is one of the problems. the recent proliferation of academic societies (or scientific), academic or professional journals, the publication requirements (number of titles) as a criterion for contests, promotions, financial aid or scholarships has increased the bureaucracy to administer it with a possible prejudice to the existing distortions to the development of science.
