Objective: To analyze the teachers’ view on the difficulties and the contribution of the assessment process to an undergraduate program in dentistry at a university in Fortaleza, Ceará Methods: This is a descriptive research with a qualitative approach. Research subjects were undergraduate dentistry professors with teaching experience in such program of five years or more. Data collection was carried out from September to October 2014, through a documentary analysis of, among others, the pedagogical political project and a semi-structured interview. A thematic review was adopted to interpret data Results: The main difficulty in the assessment was quantifying the student’s performance. The influence of the assessment on professional education depends on the understanding of the assessment process and the acquired experience. Teachers recognize the punishing and pushing effect that still remain in such process and requires a major change Conclusion: Teachers should establish assessment criteria guided by their teaching goals, without forgetting the profile of graduates from their institutions. Besides, assessment should encourage learning by coping with unfavorable emotions, restoring confidence and the learning ability. The course should be based on a curricular pedagogical project supported by guiding principles, in order to drive the assessment practice and avoid any seclusion.
Removal of filling material from the root canal system is required when a previous endodontic treatment fails, what may result in the permanence of an unfavorable periapical condition. The intent is to completely remove the filling material from the root canal to achieve sufficient cleaning and shaping for successful retreatment. Objective: The aims of this article were to provide a systematic review of the different techniques of endodontic filling material associated or not with organic solvents and to analyze them critically in terms of advantages and disadvantages of each technique. Literature review: The descriptors used were “gutta-percha”, “obturation,” and “retreatment” in the following databases: PubMed, MEDLINE, Latin American and Caribbean Center on Health Sciences Information (Bireme), Latin-American and Caribbean Health Sciences (Lilacs), Brazilian Dentistry Bibliography (BBO), and Scientific Electronic Library Online (SciELO). Publications of in vitro/ex vivo and in vivo experiments without language restriction between the years 2010 and 2018 were selected. Conclusion: None of the techniques were capable of performing complete root canal cleaning, and the manual method was so effective as the automated method, although it requires longer working time. Furthermore, although this review confirmed that the solvent action did not allow a significant improvement in the removal of the filling material, ultrasound-activated irrigation proved to be an efficient adjunctive device as it could significantly reduce the volume of intracanal residuals.
Introduction: Removal of filling material from the root canal system is required when a previous endodontic treatment fails, what may result in the permanence of an unfavorable periapical condition. The intent is to completely remove the filling material inside of the root canal to achieve sufficient cleaning and shaping for successful retreatment. Objective: The aims of this article were to provide asystematic review of the different techniques of endodontic filling material associated or not with organic solvents and to analyze them critically in terms of advantages and disadvantages of each technique.
