13. Effect of adhesive system and application strategy on reduction of dentin permeability
This study evaluated the effect of adhesive systems and application strategies on dentin hydraulic conductance (HC). The buccal enamel was removed from bovine incisors to simulate laminate cavity preparations. After removing the roots and the coronal pulp, the buccal dentin was treated with EDTA solution (0.5 M) for 5 minutes, rinsed, ultrasonicated for 12 m

14. Eroded dentin does not jeopardize the bond strength of adhesive restorative materials
This in vitro study evaluated the bond strength of adhesive restorative materials to sound and eroded dentin. Thirty-six bovine incisors were embedded in acrylic resin and ground to obtain flat buccal dentin surfaces. Specimens were randomly allocated in 2 groups: sound dentin (immersion in artificial saliva) and eroded dentin (pH cycling model - 3× / cola

15. Effectiveness of immediate bonding of etch-and-rinse adhesives to simplified ethanol-saturated dentin
This study examined the immediate bond strength of etch-and-rinse adhesives to demineralized dentin saturated with either water or absolute ethanol. The research hypothesis was that there would be no difference in bond strength to dentin between water or ethanol wet-bonding techniques. The medium dentin of 20 third molars was exposed (n = 5). The dentin surf

16. Efeito do flavonÃide epigalocatequina-3-galato na resistÃncia de uniÃo de sistema adesivo de condicionamento total à dentina. / Influence of the flavonoid epigallocatechin-3-gallate on the bond strength of adhesive system to dentin
O objetivo desse estudo in vitro foi avaliar o efeito do flavonÃide epigalocatequina-3-galato (EGCG) na resistÃncia de uniÃo à dentina nos perÃodos imediato e apÃs 6 meses de armazenamento. Trinta terceiros molares humanos recÃm-extraÃdos tiveram o esmalte oclusal removidos, obtendo-se uma superfÃcie plana de dentina. Os dentes foram divididos em 5

17. Shear bond strength of self-etch and total-etch bonding systems at different dentin depths
The purpose of this study was to evaluate the dentin shear bond strength of four adhesive systems (Adper Single Bond 2, Adper Prompt L-Pop, Magic Bond DE and Self Etch Bond) in regards to buccal and lingual surfaces and dentin depth. Forty extracted third molars had roots removed and crowns bisected in the mesiodistal direction. The buccal and lingual surfac

18. Avaliação do substrato dentinário irradiado com laser de Er:YAG : resistência de união, padrão de fratura e análise ultramorfológica / Evaluation of dentin irradiated with Er:YAG laser : bond strength, failure pattern and ultramorphology analysis
The Er:YAG laser has been widely used in Dentistry and because its ability to remove mineralized dental tissues, it is indicate to be used in Operative Dentistry. As the Er:YAG laser is recent, little is known about the consequences of dental tissues irradiation and their effects on adhesive restorative procedures. Thus, the objectives of this study were to

19. Luting glass ceramic restorations using a self-adhesive resin cement under different dentin conditions
OBJECTIVES: The aim of this study was to investigate the bond strength of ceramic restorations luted using a self-adhesive resin cement (RelyX Unicem, 3M ESPE) under different dentin conditions. MATERIAL AND METHODS: In the experimental groups, ceramic restorations were luted to bovine incisors with RelyX Unicem under the following conditions: [Dry dentin]:

20. Adhesive systems: important aspects related to their composition and clinical use
This literature review article addresses the types and the main components of different etch-and-rinse and self-etch adhesive systems available in the market, and relates them to their function, possible chemical interactions and infuence of handling characteristics. Scanning electron microscopy (SEM) images are presented to characterize the interface betwee

21. 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

22. 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

23. CORRELAÇÃO ENTRE GRAU DE CONVERSÃO E RESISTÊNCIA DE UNIÃO DE SISTEMAS ADESIVOS AUTOCONDICIONANTES / CORRELATION BETWEEN DEGREE OF CONVERSION AND BOND STRENGTH OF THE SELF-ETCHING ADHESIVE SYSTEM
Objective: The aim of this study was to analyses the relationship between the degree of conversion of double bonds of self-etching adhesives and microshear bond strength on dentin. Materials and methods: For microshear testing twenty third molar caries free were selected. They had their crowns sectioned longitudinally so as to obtain slices that were randoml

24. Influência da contaminação do campo operatório na resistência de união à dentina / Influence of the contamination of the operatory Field at dentin bonding strength
Studies on contamination are difficult to compare due to the variety of experimental designs as the type of substrate, the time when contamination takes place during the adhesive procedure and how this contamination is treated in order to clean the operatory field. Thus, further studies are needed to investigate more thoroughly the conditions described in th
