Redações de vestibular: a materialização da relação entre leitura e escrita e o diálogo com a coletânea

This work aims to understand in what way the relation between reading and writing works in the writing tests of two major entrance exams from the state of São Paulo, used as a form of admission to two great universities - UNICAMP and UNESP -, as well as analyze in what way the candidates who got grades above the average dialogue with the collection of texts which is offered in the writing test proposal. In order to found these questions on theoretical material, we have done some reading of the Bakhtin circle to understand the questions that are related to the dialogism and had support in other linguists to solidify our interpretations and analyses. We understood, after the studies and analyses, that the materialization of the relation between reading and writing is present in the majority of the texts used as the corpus of our work and that the dialogue with the collection of texts is very appreciated and present in the texts that got the highest grades or were considered above the average. The writing test has always had an unique importance in the selection processes to admission to undergraduate courses, and we believe that the analyses that were proposed here can help students and teachers to better understand the valuation which is attributed to the relation between reading and writing and the use of the collection of texts in the elaboration of a text in the entrance exams

Efeito da adição de flúor e cálcio no gel clareador a base de peróxido de hidrogênio na penetração, cor e microdureza

The objective of this study was to evaluate the effect of adding calcium ions and fluoride in the formulation of a whitening gel 35% hydrogen peroxide in its penetration through the dental structure, whitening efficacy and surface hardness of dental enamel. 80 teeth bovine incisors were used, which were obtained enamel and dentin disks of the buccal surface with 6mm diameter and 2mm thick (1 mm of enamel and dentin 1mm). The samples were divided into four groups stratified according to the protective substance / remineralizing added to the gel of hydrogen peroxide 35%: Group Ca - Calcium gluconate 0.5%; Group F - Sodium fluoride 0.2%; Group Ca + F - Calcium gluconate 0.5% and Sodium Fluoride 0.2%; Control group - no substance was added. The initial color of the samples and the hardness of the enamel were measured before the bleaching procedures. The specimens from each group were placed on a metallic support on which there was a simulated pulp chamber, which was filled with acetate buffer to collect and stabilize the penetrated peroxide. The respective bleaching treatments were applied 3 times, total of 30 minutes of application. The amount of peroxide which passed through the samples was determined by absorbance spectrophotometry. The hardness of the samples was measured immediately after bleaching. Next, the samples were immersed in artificial saliva for 7 days, after which the final color was evaluated. Data were statistically analyzed adopting a 5% significance level
