4. Avaliação da capacidade de remoção da camada residual dentinária com o uso do Endo PTC em diferentes formulações, associado a duas concentrações de hipoclorito de sódio, utilizando ou não irrigação final com EDTA. / Evaluation of the ability to remove the smear layer of dentin with the use of Endo PTC in different formulations, combined with two concentrations of sodium hypoclorite, with or without final irrigation with EDTA.
The action of the instruments on the walls of the root canal provides the smear layer development, which is an extract of organic and inorganic matter, with amorphous appearance, irregular and granular surface which is set down on the dentin surface in the measure that its formation occurs, and when it is not removed, can interfere on the desired sealing dur

5. Endodontic irrigation effect on microhardness, morphology and roughness in primary and permanent teeth / Influencia da irrigação endodontica sobre a microdureza, morfologia e rugosidade de dentes deciduos e permanentes
Irrigation solutions, endodontic auxiliary chemical substance, and chelating agents used on root canal treatment might yield changes in the chemical composition and physical properties of dentin surface, and affect its interaction with materials used for coronal sealing. Thus, studies are required to select a suitable chemical agent, which has minimal effect

8. Role of reduced sulfur compounds in nutrition of Propionibacterium acnes.
In a study of the nutritional requirements of Propionibacterium acnes, acid hydrolyzed casein was shown to be the preferred nitrogen source in a glycerol-salts medium. Of 22 individual amino acids tested, only cysteine supported growth in the glycerol-salts medium. This indicated a requirement not only for amino nitrogen but also for reduced sulfur. In the p
