Avaliação in vitro da resistência adesiva de braquetes ortodônticos variando-se o tempo de armazenamento e o tipo de fotoativação: luz halógena e led

O objetivo deste estudo in vitro foi comparar os efeitos da fotoativação pelos sistemas luz halógena e LED na adesão de braquetes ortodônticos em diferentes tempos pós-colagem (imediato, 24h e 7d). Braquetes com adesivo pré-aplicado (Gemini series; APC adhesive precoated brackets; 3M Unitek, USA) foram colados na superfície vestibular de dentes bovinos. O esmalte dos dentes foi condicionado utilizando-se o primer auto-condicionante (Transbond SEP, 3M Unitek, USA) em todos os espécimes, conforme recomendações do fabricante. Setenta e dois dentes foram divididos em 2 grupos (n=36), conforme o sistema de fotoativação (luz halógena ou LED) e sub-divididos (n=12) de acordo com o tempo pós-colagem. Para os grupos luz halógena, o tempo de fotoativação foi de 20s e para os grupos LED foi de 10s. O teste de resistência ao cisalhamento foi realizado com auxílio de uma máquina de ensaios universal nos diferentes tempos pós-colagem: imediato, 24h e 7d. O valor médio de adesão para os grupos luz halógena foi de 20,01±5,24MPa e, para os grupos fotoativados pelo sistema LED 17,35±5,07MPa, sendo estes resultados estatisticamente diferentes. Quando comparado o efeito do tempo pós-colagem, os resultados revelaram que os valores de adesão foram significantemente maiores para o tempo de 7d. O resultado do teste ANOVA 2 – fatores revelou não existir diferença estatística entre a interação sistema de fotoativação e tempos pós-colagem. O teste de Tukey mostrou que para as 4 condições experimentais nos tempos imediato e 24h, os resultados não diferiram estatisticamente, independentemente do sistema de fotoativação. Somente com relação ao grupo luz halógena-7d, os resultados mostraram diferenças estatisticamente significantes. O grupo LED-7d desempenhou comportamento intermediário entre os grupos. O índice de adesivo remanescente não revelou diferenças... (Resumo completo, clicar acesso eletrônico abaixo)

Frontonasal dysplasia: clinical evaluation on audiological and brainstem electrophysiological profiles

Frontonasal dysplasia (FND) is a rare malformative complex affecting the frontal portion of the face, the eyes and the nose; it may occur singly or associated with other clinical signs. No systematic studies describing hearing in this condition were found. AIM: To evaluate hearing sensitivity and sound stimulus conduction from cochlea to brainstem in patients with clinical signs of FND. METHODS: 21 patients with isolated or syndromic FND were submitted to a clinical (otological/vestibular antecedents and otoscopy) and instrumental (pure tone and speech audiometry, tympanometry and brainstem auditory evoked response) hearing evaluation. DESIGN: A clinical, cross-sectional observational prospective study. RESULTS: Hearing thresholds were normal in 15 (70%) patients, abnormal in 5 (25%), mostly with conductive hearing loss; one patient did not cooperate with testing. The tympanometric curve was type A in 30 (72%) ears, type C in 5 (12%), type As in 4 (9%) and type B in 3 (7%). The auditory brainstem response (ABR) showed no abnormalities. CONCLUSION: Patients with FND showed no abnormalities in the auditory system from cochlea to brainstem in this study. Mild conductive hearing loss found in some is probably related to cleft palate. Further evaluation of hearing pathways at higher levels is recommended.

As Melhores redações da FUVEST 2010: uma análise dialógica

This research analyzes the 53 best university entrance exams essays of 2010 of FUVEST - University Foundation for University Entrance Exams, which were published on the institution website, indicating that they were considered the best in the exam. The objective of the analysis was to identify similarities and differences between the essays, based on dialogic approach. We analyzed aspects such as: the way students addressed the subject, the language and organization of writing; the different ways of argumentation; the most used quotes; dissertation structure and the way the students considered the discourse genre writing. The study also compared the essays based on the way in which the genre is addressed in schools and pre-university preparatory courses, which gave us parameters to evaluate the extent to which this teaching can help students or otherwise confuse them. Through the analysis, we can deduce what the institution values, which helps to demystify some of the so-called known “recipes” for good writing

A escolha da profissão docente: perfil dos alunos do curso de Pedagogia da UNESP/Bauru no ano de 2011

Several aspects interfere when it comes to choose a career. Some of which are family and cultural influence; and even lack of opportunities. Such aspects were greatly taken into consideration for defining the subject of this research which is to analyze the reasoning Pedagogy students from UNESP (Universidade Estadual Paulista – University of São Paulo State) used when choosing their academic career, and to assess the students’ profile who were taking this course in 2011 as well as the influence of students’ socioeconomic conditions. An empiric approach with a qualitative survey was chosen to develop this research which was conducted with a questionnaire appliance and with a semi-structured interview with randomly selected students. A theoretical study about the specifics of the academic career and a fully comprehension of the legal / regulatory aspects of this profession in Brazil were also conducted. The survey results showed that most students were women, supporting the fact that this career has become a female profession. Characteristics such as vocation and mission, presented on literatures as the specifics of this profession were clearly seen in the survey results. Several students went to public schools and are labeled into the classes C and D in social economical status; furthermore almost 50% had not chosen Pedagogy as a first choice for a major. However, most of the students do not think that their social economical status had influence in their choice. Nevertheless some students claimed that their options were not their first wish and their choice was made by the easier possibility of entering and concluding the course besides the prompt need of these professionals after graduating in the job market. The students’ education background were also discussed in the research... (Complete abstract click electronic access below)

História do desenvolvimento do conceito de força: um estudo visando contribuições para o ensino de física no nível médio

This study presents the results of a study on the development of the concept of force and their possible applications in physics teaching. The historical study has focused on Aristotelian natural philosophy, medieval theories of strength in impressed and on classical Newtonian mechanics. The Newtonian concept of force was also an object lesson of physics analyzed in this study. In this lesson, conducted in a preuniversity course, spontaneous conceptions or alternative conceptions of students about the concept of force proved very entrenched, resulting in studies on the Model Change on Conceptual and epistemological obstacles in view Bachelardian. The theoretical frameworks adopted led us to trace parallels between spontaneous conceptions revealed by the students and some views about the concept of force found in the study of history. The results show that while some old conceptions have been replaced by scientifically Newtonian concept of force, they are still present in the students' ideas and resist to changes even after the study of Newton's laws. Like main result shows that the history of science can be a great ally for the deconstruction of alternative conceptions, particularly when these concepts were previously presented and overcome the course of history of the development of a concept

Estudo in vitro da anatomia das projeções de esmalte cervical em dentes molares

The cervical enamel projection (CEP) is an anatomic variation that can be found in the cement enamel junction, it´s recognition and early diagnosis improves outcome the tooth involved, allowing greater efficiency in treatment. The knowledge of the location, grade and incidence of CEP is decisive on prevention and treatment of periodontal disease. It were studied 1200 molars (600 mandibular molars and 600 maxillary molars) separated from the collection of teeth on the Discipline of Anatomy in FOSJCampos - UNESP. Each group of 600 teeth was separated from the second side (300 teeth) and the second type (first, second or third molar). Each tooth had thoroughly inspected the cervical region, in all their faces, in order to verify the incidence and the grade of CEP in each surface. It was found that the CEP covered in 278 (23,17%) teeth was 146 (52,52%) mandibular molars and 132 (47,48%) maxillary molars. The CEPs were concentrated on a tooth surface in 222 (79,86%) teeth, in two surfaces 53 (19,06%) teeth, and in three surfaces in three (1,08%) teeth. From the total of 4.800 surfaces examined the CEPs were found in 337 surfaces, and 228 (67,66%) surfaces of the grade I, 60 (17,8%) grade II and 49 (14,54%) grade III. The buccal surface presented 207 (61,42%) CEP, the lingual surface in 57 (16,91%), the mesial surface in 35 (10,39%) and the distal surface in 38 (11,28%) CEP. The results of this study demonstrated that the CEPs have focused more on the mandibular teeth on only one surface of the tooth, the grade I was the most found and the buccal surface the most involved

Efeito da ativação física e química do gel clareador na velocidade de penetração do peróxido de hidrogênio: estudo in vitro

This study evaluated the effect of physical and chemical activation on the speed of penetration of hydrogen peroxide bleaching agents present in different concentrations through the enamel and dentin. One hundred and twenty bovine incisors were used, which were obtained enamel/dentin discs of the buccal surface, with 6 mm in diameter. The samples were divided into six groups: G1 - Hydrogen Peroxide Gel 20%, G2 - Hydrogen Peroxide Gel 20% with light activation, G3 - Hydrogen Peroxide Gel 20% with Manganese Gluconate; G4 - Hydrogen Peroxide Gel 35%; G5 - Hydrogen Peroxide Gel 35% with the light activation and G6 - Hydrogen Peroxide Gel 35% with Manganese Gluconate. The specimens were placed in a transparent support on which there was a substance sensitive to hydrogen peroxide immediately below and in contact with the specimen. After the procedures for applying the gel for each group, one video camera was positioned and operated to monitor the time of penetration of peroxide in each specimen. The recording ended after changing the color of the fluid revealed in all specimens and times were noted for comparison. ANOVA analysis showed that concentration and type of activation of bleaching gel significantly influenced the diffusion time of hydrogen peroxide (P 0.05). 35% hydrogen peroxide showed the lowest diffusion times compared to the groups with 20% hydrogen peroxide gel. The light activation of hydrogen peroxide decrease significantly the diffusion time compared to chemical activation. The highest diffusion time was obtained with 20% hydrogen peroxide chemically activated. The diffusion time of hydrogen peroxide was dependent on activation and concentration of hydrogen peroxide. The higher concentration of hydrogen peroxide diffused through dental tissues more quickly

Estudo da anatomia interna dos incisivos laterais superiores pelos métodos radiográficos digital e convencional

The maxillary lateral incisor has a very peculiar and internal morphology that can be influenced by the its external anatomy such as supernumerary roots and ruts deep root, which often hinders an effective endodontic treatment. Generally, this tooth have a single root with one root canal, but teeth with two to four channels can be found. The main canal can present ramifications such as accessory canals, laterals, collaterals, recorrents and apical deltas. All this factors interfere directally on endodonthics treatment. The objective of this work is a study of the internal anatomy of the maxillary lateral incisors by digital and conventional radiographics methods, comparing the results obteined by each method Six hundred upper lateral incisor were used in this study teeth of the collection of the Department of Anatomy ICT – UNESP. All the teeth were radiographed by vestibular face, using a digital radiographic unit(Dabi Atlante). After this step, all the teeth underwent by conventional radiographic technique(Kodak 2200) so that the results obtained were compared. To classify the channel system, it was adopted the classification of Pucci and Reig. All data obtained by digital technique were compared with those obtained in the conventional technique and were subjected to statistical analysis
