14. Chemical and topographic analysis of treated surfaces of five different commercial dental titanium implants
We present a detailed investigation of the surface characteristics of five commercial titanium implants with different surface finishing (double acid etching, anodization and incorporation of Ca/P, acid etching and deposition of Ca/P, hydroxyapatite-blasting, acid etching and Ca/P-blasting) produced by five different manufacturers. A set of experimental tech

16. Análise morfológica e da resistência adesiva dos tecidos dentais duros irradiados com lasers de pulsos ultracurtos / Evaluation of dental hard tissues irradiated with ultra-short pulsed lasers. Influence on surface morphology and microtensile bond strength
The development of restorative dentistry has reached the era of esthetic adhesive restorations and minimally invasive approach, for which innovative techniques and advanced materials are constantly introduced. Conservative techniques aim not only to remove carious dental substrate, but also to prepare cavity surfaces for adhesive restoration. The main object

17. Surface degradation of glass ceramics after exposure to acidulated phosphate fluoride
OBJECTIVE: This study evaluated the surface degradation effect of acidulated phosphate fluoride (APF) gel exposure on the glassy matrix ceramics as a function of time. MATERIAL AND METHODS: Disc-shaped ceramic specimens (N = 120, 10/per ceramic material) were prepared in stainless steel molds (inner diameter: 5 mm, height: 2 mm) using 6 dental ceramics: 3 in

18. Ação antibacteriana e potencial cariostático de sistemas adesivos autocondicionantes
This study evaluated in vitro the antibacterial activity and in situ the cariostatic effect of self-etching adhesives system. In a logical sequence, three scientific articles were developed. The first was a literature review about the use of selfetching adhesives systems in the prevention of dental caries. The second evaluated the inhibition zone 9 self-etch

19. Resistência à microtração de dois cimentos resinosos autocondicionantes em função do tipo de substrato dental e tempo de armazenagem em água / Resistance of microtensite two resin cemesnts self-etching depending on the type of substrate and dental time water storage
O objetivo neste estudo foi comparar a resistência de união a microtração de dois cimentos resinosos autocondicionantes (Rely X U100 - 3M ESPE e Multilink - IVOCLAR-VIVADENTE) em função do tipo de substrato dental (dentina oclusal e esmalte vestibular) e tempo de armazenagem em água (24 horas, três e seis meses). Foram utilizados sessenta terceiros m

20. Titanium dental implant surfaces
Osseointegration has been defined as "a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant". However, titanium and its alloys cannot directly bond to living bone after being implanted into the body. The osseointegration of titanium dental implants is critically dependent on the implant surface

21. AVALIAÇÃO DA RESISTÊNCIA DE UNIÃO DE DIFERENTES SISTEMAS DE CIMENTAÇÃO ADESIVA AO ESMALTE E A DENTINA / BOND STRENGTH EVALUATION OF DIFFERENT SYSTEMS FOR ADHESIVE CEMENTATION TO ENAMEL AND DENTIN
Objective: The aim of this study was to evaluate the bond strength to enamel and dentin of a self-adhesive resin cement applied with different cementation strategies, using a conventional resin cement as control. Material and Methods: Sixty healthy human molars were selected and allocated into 6 groups (n=10) according to cementation system and dental substr

22. Microtensile bond strength of a simplified self-etching adhesive to enamel : influence of multiple coats = Resistência adesiva à microtração ao esmalte de um adesivo auto-condicionante simplificado : influência de múltiplas camadas / Resistência adesiva à microtração ao esmalte de um adesivo auto-condicionante simplificado : influência de múltiplas camadas
Este estudo testou a hipótese nula de que o número de camadas de aplicação de um primer autocondicionante pode não influenciar não resistência da interface adesiva resina/esmalte à microtração. Dentes bovinos foram nivelados, para expor os prismas de esmalte, utilizando-se lixa d´água #600. Os dentes foram divididos em dois grupos: FB 1 camada, F

23. Influência da dentina sadia e afetada por cárie na resistência de união de sistemas adesivos e cimentos de ionômero de vidro em dentes decíduos - estudo in vitro / Influence of sound or caries-affected dentin on the bond strength of adhesive systems and glass ionomer cements in primary teeth an in vitro study
The aim of this study was to evaluate the influence of sound and caries-affected dentin of primary teeth restored with different materials, regarding bond strength and nanoleakage. Seventy two primary second molars received standardized occlusal preparations were randomly assigned in two groups. One group was nominated as sound dentin [SD] (n=36), and the ot
