1. Effect of Etching Temperature on Surface Properties of Ti6Al4V Alloy for Use in Biomedical Applications
The objective of this study is to evaluate the surface physicochemical properties of Ti6Al4V alloy after etching with a piranha’s solution at temperatures of 25 °C, 40 °C, and 60 °C for 30 min. Scanning electron microscopy with energy-dispersive X-ray spectroscopy, optical profilometry, X-ray diffraction, and wettability analyses were used to characteri

3. Análise de interfaces de sistemas restauradores diretos em esmalte e em dentina humanos
RESUMO O presente estudo visou caracterizar a interface entre resina e substrato dentário submetida aos processos restauradores convencional e autocondicionante, levando a observar a presença de gaps e infiltração dos sistemas adesivos nos substratos dentários. A análise foi realizada em dois substratos dentários: o esmalte e a dentina. Seis dentes h�

4. Long-term bonding efficacy of adhesives containing benzodioxioles as alternative co-initiators
Abstract This study evaluated the three-year lifespan of the bond to dentin of experimental self-etch adhesives containing benzodioxole derivatives – 1,3-benzodioxole (BDO) and piperonyl alcohol (PA) – as co-initiator alternative to amines. Adhesive resins were formulated using Bis-GMA, TEGDMA, HEMA, camphorquinone and different co-initiators: BDO, PA or

5. Effect of the time-point of acid etching on the persistence of sealer residues after using different dental cleaning protocols
Abstract: Endodontic sealer residues remaining within the pulp chamber dentin after root canal obturation and cleaning with various solvents may compromise the appearance and the durability of dental restorations. Acid etching is routinely performed prior to application of dentine adhesive systems, but is effect on residual sealer material and the optimal ti

6. Influence of pH, bleaching agents, and acid etching on surface wear of bovine enamel
ABSTRACT Development of new materials for tooth bleaching justifies the need for studies to evaluate the changes in the enamel surface caused by different bleaching protocols. Objective The aim of this study was to evaluate the bovine dental enamel wear in function of different bleaching gel protocols, acid etching and pH variation. Material and Methods

7. Early osseointegration driven by the surface chemistry and wettability of dental implants
Objective The objective of this study was to investigate the impact of two different commercially available dental implants on osseointegration. The surfaces were sandblasting and acid etching (Group 1) and sandblasting and acid etching, then maintained in an isotonic solution of 0.9% sodium chloride (Group 2). Material and Methods X-ray photoelectron spect

8. Effect of a desensitizing dentifrice on the bond strength of different adhesive systems
AIM: This in vitro study evaluated the effect of using a dental hypersensitivity treatment on the bond strength to dentin of etch-and-rinse and self-etching simplified adhesive systems. METHODS: 40 healthy molars were used. The crowns of teeth were removed at the dentinoenamel junction, and remaining roots were sectioned in the mesiodistal direction along th

9. Influence of acid etching on shear strength of different glass ionomer cements
AIM: To assess the influence of dental etching on the shear strength of different glass ionomer cements. METHODS: The crown of 60 bovine incisors was prepared to obtain a flat, smooth surface, were attached to a PVC tube and randomly divided into six groups: Group 1 - Riva Self Cure without etching; Group II - Riva Self Cure with pre-etching; Group III - Max

10. Influência de materiais obturadores e agentes de limpeza na resistência da união e interface adesiva de pinos de fibra de vidro à dentina intrarradicular / Influence of filling materials and cleaning agents on bond strength and adhesion interface of glass fiber post to radicular dentin
The aim of this in vitro study was to evaluate the post-cement-dentin adhesive interface quality and the effect of different filling materials and cleaning agents on the bond strength of glass fiber posts to primary root dentin. This study included 156 roots of bovine primary teeth which were endodontically treated and assigned to four groups (39 teeth each

11. Influência da limpeza mecânica com e sem o uso do microscópio operatório na resistência adesiva intrarradicular / Influence of mechanical cleaning with and without the use of the operating microscope in intraradicular adhesive strength
In endodontic treatment, there is an imperative need to restore the tooth, reestablishing its functions, since there is always a risk of recontamination of the root canal system and fractures. These risks are higher when there is loss of dental structure, requiring intraradicular posts to hold the restoration procedures in place. For the definitive and immed

12. The influence of surface treatment on the implant roughness pattern
An important parameter for the clinical success of dental implants is the formation of direct contact between the implant and surrounding bone, whose quality is directly influenced by the implant surface roughness. A screw-shaped design and a surface with an average roughness of Sa of 1-2 µm showed a better result. The combination of blasting and etching ha
