As fontes do método analítico de leitura de João Köpke (1896-1917)

After two decades advertising and defending the synthetic method, João Köpke became active disseminator of analytical method for teaching reading. In five te xts published between 1896 and 1917, produced in different circumstance s for different publics readers, Köpke seeks the support of American and European authors, for their principles as well as for the education experience, to his analytical method. as by theirs principles as by theirs educational experiences. Among those authors: J. Jacotot, A. Bain, A. Meiklejohn, J. Froebel, C. Parker, G. Stanley Hall and J. Chubb. In this article, attention is given to repeated American references with special emphasis on the psychology of Stanley Hall and the method of teaching reading of Meiklejohn, highlighted and placed on convergence by Köpke in his final writings.

Cidadania e nacionalidade como formas de exclusão

O presente trabalho versa sobre o acesso de estrangeiros ao território nacional. Essa limitação restringe direitos fundamentais da maioria dos imigrantes, além de expô-los a uma condição de vulnerabilidade que permite que sejam explorados pelo setor econômico de produção e perseguidos pela polícia. O Estado não costuma ver o imigrante como “vítima”, mas como marginal”. Se todos os homens são fundamentalmente iguais em razão de sua igual dignidade, se a constante comunicação e movimentação são imprescindíveis e se é moralmente impossível justi*car os privilégios de pessoas porque nasceram em determinado território ou de determinados genitores, então as funções discriminadoras dos conceitos de cidadania e nacionalidade perdem sua justificativa.

Fracture resistance of simulated immature teeth after different intra-radicular treatments

The aim of this study was to evaluate the fracture resistance of simulated immature teeth after different intra-radicular treatments. Crowns and roots of bovine incisors were cut transversally and removed to simulate immature teeth. Root canal preparation and flaring were performed using a bur in crown-apex and apex-crown direction. The samples were distributed into 5 groups (n=10): Positive control (PoC) - no root canal flaring or filling; Negative control (NeC) - teeth were sectioned and their root canals were flared; Direct anatomical glass fiber post (RaP) - #2 Reforpost main glass fiber post relined with composite resin; Double tapered conical glass fiber posts (ExP) - #3 Exacto glass fiber post; and #2 Reforpost main glass fiber + Reforpin accessory glass fiber posts (RrP). In RaP, ExP and RrP, 4.0-mm apical plugs were done with MTA Angelus. The specimens were embedded in polystyrene resin inside cylinders and the periodontal ligament was simulated with a polyether-based impression material. The specimens were submitted to compressive fracture strength test (0.5 mm/min at 135° relative to the long axis of the tooth) in a servo-hydraulic mechanical testing machine MTS 810. Data were subjected to one-way ANOVA and Dunnett's C or Tukey's tests (α=0.05). The control groups (PoC and NeC) showed lower fracture strength than the experimental groups. NeC presented the lowest resistance and ExP presented the highest resistance among the experimental groups. The flaring procedures produced a detrimental effect on the fracture resistance of the bovine teeth. Glass fiber intra-radicular posts increased significantly the fracture resistance of simulated immature teeth.

Influence of Insertion Techniques for Resin Cement and Mechanical Cycling on the Bond Strength Between Fiber Posts and Root Dentin

Purpose: To evaluate the effect of the insertion technique for resin cement and mechanical cycling on the bond strength between fiber posts and root dentin.Materials and Methods: Sixty-four single-rooted bovine teeth were endodontically prepared to receive glass-fiber posts. The insertion of cement into the root canal was performed using one of the following techniques: POS, insertion with the post; LEN, the use of a lentulo-type drill; EXP, insertion with a straight-tip explorer; or CEN, the use of a Centrix syringe. Half of the specimens were mechanically cycled. All specimens were sectioned into slices of 1.8 mm for the push-out test and 0.5 mm for analysis of the cement layer quality.Results: The insertion technique affected the interaction between factors (bond strength and mechanical cycling; p < 0.0001). Insertion of the Centrix syringe after mechanical cycling showed the highest bond values (13.6 +/- 3.2 MPa). Group-to-group comparisons for baseline and cycled conditions indicated that mechanical cycling significantly influenced the bond strength (p < 0.0001) of the POS and CEN groups. The quality of the cement layer did not differ between the techniques when evaluated in the middle (p = 0.0612) and cervical (p = 0.1119) regions, but did differ in the apical region (p = 0.0097), where the CEN group had better layer quality for the two conditions tested (baseline and cycled).Conclusion: The use of the Centrix syringe improved the homogeneity of the cement layer, reducing the defects in the layer and increasing adhesive strength values to dentin, even after mechanical cycling.
