Development of new standard procedures for the evaluation of dental composite abrasive wear

This article discusses the development of a test bench and a methodology for the study of composite resin abrasive wear. To evaluate the operation of the test bench and to compare the proposed methodology with other existing ones, a study was made of the five composites most commonly used by dentists.The one-way ANOVA method and the Tukey test were used to statistically analyze the results by multiple comparisons of the groups of resins tested. Using the proposed methodology, these resins were classified in an increasing order of abrasive wear strength, as follows: Charisma (the lowest abrasive wear strength), Tetric, TPH, Herculite and Z-100 (the highest abrasive wear strength) (P < 0.05). In comparison to other methodologies, the results of the proposed methodology presented the lowest coefficient of variation. (C) 2002 Elsevier B.V. B.V. All rights reserved.

This article reflects on the continuing education of science teachers and, for that, it was conducted a documental analysis of the Law of Guidelines and Bases of Educations (Law No. 9394/96) and a bibliographical research to make a survey and a study about the authors with recognized contribution in this area, focusing on the following items (i) aspects of legislation and public policies for the continuing education on Basic Education teachers; (ii) teaching knowledge needed in their professional training; and (iii) continuing education of science teachers. It was concluded that teachers’ professional development should happen through institutional continuing education, guided by a work plan, so that they can effectively develop their as mediators between the students' interaction with the information obtained, so that the teaching-learning process can happen and consistent scientific knowledge can be constructed by students.
