Influência da reinstrumentação do degrau apical radicular após o posicionamento primário do cone principal de guta-percha noselamento apical

The aim of this study was to evaluate in vitro the apical leakage after the apical re-preparation and replacement of the principal gutta-percha point plus endodontic sealer (Sealer 26TM). Sixty extracted human canines were prepared by using a step back technique up to size 50 K type file apically. At each change of instrument the canals were irrigated with distilled water. After that step, the external surface roots were coated and subdivided into six groups with ten roots each: I – single gutta percha point technique; II – lateral condensation and III – hybrid technique. The IV, V and VI groups were similar to others groups but after to place the principal gutta percha point, it was removed, re-prepared up to size 60K file and in sequence replaced the principal gutta percha point and the root canal filling finished. The specimens were immersed in 2% Rhodamine BTM for 7 days at 37 oC. The apical leakage was measured by Image ToolsTM program. With Kruskal Wallis test statistical analysis showed that there was no significant difference between the techniques (p > 0.05).

A pesquisa em psicologia: ensaio sobre a Psicologia enquanto ciência, a pesquisa qualitativa e o uso da entrevista como principal instrumento de coleta de dados

For constituting itself a science, Psychology has coursed along way. From the time he was considered a Philosophy’s discipline until to be recognized as a legitimate science, Psychology had to devoteto the definition of its object of study, the development and refinement of theoretical-methodological frameworks and, in particular, to consolidation process of their research strategies and knowledge construction. Therefore, in order to regard the demands of the classical scientific paradigm, which is very influenced by Positivism, Psychology made use, initially, of quantitative methodology and laboratory research. This article presents some of the process of identity construction of Psychology as a science, focusing on its transition path between the quantitativist paradigm of scientific knowledge production to the qualitativist paradigm, until that is more commonly practiced nowadays: the collaborative use of these methodological strategies. For presenting the qualitative researching Psychology, we discussed, beyond its proposal and differentiation elements in relation to quantitative research, the different methods used for this mode and, in particular, the interview - which is considered the main way of data collection in surveys conducted by psychologists and, therefore, it is an important element the process of knowledge building that science, in addition to being the most qualified space for dialogue between there searcher and the research subject.
