2. Evaluation of the effect of chlorhexidine and sodium hypochlorite in adhesive cementation of fiber posts - in vitro study
Resumo Introdução A fixação de pinos de fibra de vidro é realizada através de um processo adesivo. Falhas podem ocorrer na adesão devido à degradação hidrolítica dos adesivos, ou pela degradação das fibras colágenas da camada híbrida por enzimas intrínsecas. Objetivo Avaliar o efeito do tratamento com clorexidina e hipoclorito de sódio sob

4. Effect of peracetic acid used as single irrigant on the smear layer, adhesion, and penetrability of AH Plus
Abstract The aim of this study was to evaluate the effect of peracetic acid (PAA) as a single irrigant on the smear layer, on the intraradicular dentinal bond strength, and on the penetrability of an epoxy-based resin sealer into the dentinal tubules. A total of 120 roots were distributed into 4 groups according to the irrigant used in root canal preparation

5. Effect on adhesion of a nanocapsules-loaded adhesive system
Abstract This study aimed to evaluate the in situ degree of conversion, contact angle, and immediate and long-term bond strengths of a commercial primer and an experimental adhesive containing indomethacin- and triclosan-loaded nanocapsules (NCs). The indomethacin- and triclosan-loaded NCs, which promote anti-inflammatory and antibacterial effects through co

6. The effect of silver nanoparticles on composite shear bond strength to dentin with different adhesion protocols
Abstract In Dentistry, restorative materials and oral bacteria are believed to be responsible for restoration failure. To make long-lasting restorations, antibacterial agents should be made. Inorganic nanoparticles and their nano composites are applied as good antibacterial agents. Objective The purpose of this study was to investigate the effect of silver

7. Influence of antimicrobial solutions in the decontamination and adhesion of glass-fiber posts to root canals
AbstractObjective This study evaluated the effect of root canal disinfectants on the elimination of bacteria from the root canals, as well as their effect on glass-fiber posts bond strength.Material and Methods Fifty-three endodontically treated root canals had post spaces of 11 mm in length prepared and contaminated with E. faecalis. For CFU/ml analysis, ei

8. Mechanical, antibacterial and bond strength properties of nano-titanium-enriched glass ionomer cement
The use of nanoparticles (NPs) has become a significant area of research in Dentistry. Objective The aim of this study was to investigate the physical, antibacterial activity and bond strength properties of conventional base, core build and restorative of glass ionomer cement (GIC) compared to GIC supplemented with titanium dioxide (TiO2) nanopowder at 3% an

9. Blood clot stabilization on root dentin conditioned by the combination of tetracycline and EDTA
AIM: To assess the combined use of tetracycline (TTC) and ethylenediaminetetraacetic acid (EDTA) on clot formation, considering that EDTA may neutralize TTC acidity. METHODS: Planed human tooth roots were treated with saline solution, EDTA, TTC and their combination (EDTA followed by TTC and TTC before EDTA). Fresh human blood was applied on the condit

10. Etidronate from Medicine to Endodontics: effects of different irrigation regimes on root dentin roughness
An increase in dentin roughness, associated with surface composition, contributes to bacterial adherence in recontaminations. Surface roughness is also important for micromechanical interlocking of dental materials to dentin, and understanding the characteristics of the surface is essential to obtain the adhesion of root canal sealers that have different phy

11. Avaliação in vitro da morfologia e da resistência de união de adesivos à dentina humana hígida ou submetida à ciclagem erosiva e irradiada com os lasers de Er:YAG e Er,Cr:YSGG / In vitro evaluation of the morphology and the bond strength of adhesives to sound and artificially eroded human dentin irradiated with Er:YAG and Er,Cr:YSGG laser
A erosão dental provoca alterações histológicas complexas na dentina e, apesar do aumento da ocorrência desta patologia na última década, a literatura apresenta poucos estudos sobre a adesão na dentina erodida. Com o aprimoramento da tecnologia e o conhecimento de que os lasers de érbio apresentam grande afinidade pela água e hidroxiapatita, sua ut

12. Resistência adesiva dos cimentos resinosos convencionais e autoadesivos à dentina contaminada por saliva / Bond strength of different composite resin cements and dentin interfaces contaminated with saliva
Many dental injuries require indirect restorations fixed by adhesive cements. In some situations is not possible to isolate the operative field, which can lead to contamination by saliva of the dentin. The aim of this study was to analyze the treatment of dentin contaminated with saliva on shear bond strength of conventional and self-adhesive resin cements.
