25. Characteristics of the dentinária surface and Smear Layer formed by diamantados abrasive instruments: rotatory conventional, rotatory CVD and CVD for ultrasound. Study in vitro / Características da superfície dentinária e do esfregaço formado por instrumentos abrasivos diamantados: rotatório convencional, CVD rotatório e CVD por ultra-som. Estudo in vitro
Abrasive diamond instruments are a recent development, obtained through a technique called Chemical Vapor Deposition (CVD), used in ultrasound as a new possibility in dental cavity preparation. Traditionally, cavity preparations are made with conventional abrasive rotary diamond burs (IADR), forming a thick smear layer. Upon the development of new adhesive s

26. Estudo in vivo da infiltração coronaria em dentes de cães tratados endodonticamente e protegidos por diferentes materiais / In vivo study of the coronal leakage in endodontically treated dog s teeth protected by different materials
This in vivo study evaluated the microbial coronal leakage in dogs endodontically treated teeth, post space preparation and with the remaining filling protected or not with different materiais. A hundred thirty six root canais of incisives and pre-molars of 6 dogs were used. After the anesthesia of the animais, these teeth were endodontically prepared. Hundr

27. Influência de procedimentos restauradores e endodônticos na distribuição de tensões analisada pelo método dos elementos finitos tridimensional
The preservation of a healthy dental structure is important for the maintenance of the integrity and balance of the mastigatory system. The purpose of this study was to evaluate the stress distribution in a maxillary central incisor induced by the preparation cavity, and endodontic and restorative procedures when submitted load through element finite threedi

29. "Relationship between contraction stress and degree of conversion in dental composites" / "Relação entre tensão de contração e grau de conversão em compósitos restauradores"
ABSTRACT The contraction stress developed during polymerization of composites bonded to cavity walls cavity is often associated with marginal gaps and interfacial failure. The aim of this study was to verify the relationship between contraction stress and degree of conversion (DC) in four composites (Z250, A110 3M ESPE; Tetric Ceram, Heliomolar Vivaden
