13. Stability of the anterior arm of three different Hyrax hybrid expanders: an in vitro study
RESUMO Introdução: a força aplicada sobre os dentes por expansores ortopédicos fixos já foi estudada antes, mas não a força aplicada sobre os mini-implantes ortodônticos (MIOs) usados para expandir a maxila com expansores do tipo Hyrax híbrido (EHH). Objetivo: o objetivo desse artigo foi avaliar a segurança clínica dos componentes (MIO, abutmen

14. Microtensile bond strength of CAD/CAM materials to dentin under different adhesive strategies
Abstract: The present study aimed to evaluate the microtensile bond strength (μTBS) of novel computer-aided design/computer-aided manufacturing (CAD/CAM) restorative materials to dentin using different adhesive strategies. Thirty-two crowns were milled using CAD/CAM materials (Vita Mark II as control, Vita Suprinity, Vita Enamic and Lava Ultimate) and luted

15. Instrument Design May Influence Bacterial Reduction During Root Canal Preparation
Resumo A proposta deste estudo foi avaliar a redução bacteriana promovida pelos sistemas ProTaper Next e Twisted File comparando-os ao sistema ProTaper Universal e técnica manual. Sessenta raízes disto vestibulares de molares superiores esterilizadas com óxido de etileno foram contaminadas com Enterococcus faecalis. Após incubação por 21 dias, amostr

16. Misfit and fracture load of implant-supported monolithic crowns in zirconia-reinforced lithium silicate
Abstract Zirconia-reinforced lithium silicate (ZLS) is a ceramic that promises to have better mechanical properties than other materials with the same indications as well as improved adaptation and fracture strength. Objective In this study, marginal and internal misfit and fracture load with and without thermal-mechanical aging (TMA) of monolithic ZLS and

17. Quantitative transportation assessment in curved canals prepared with an off-centered rectangular design system
Abstract The purpose of this study was to assess the ability of an off-centered rectangular design system [ProTaper Next (PTN)] to maintain the original profile of the root canal anatomy. To this end, ProTaper Universal (PTU), Reciproc (R) and WaveOne (WO) systems were used as reference techniques for comparison. Forty clear resin blocks with simulated curve

18. Single Flexible Nanofiber to Simultaneously Realize Electricity-Magnetism Bifunctionality
In order to develop new-typed multifunctional composite nanofibers, PANI/Fe3O4/PVP flexible bifunctional composite nanofibers with simultaneous electrical conduction and magnetism have been successfully fabricated via a facile electrospinning technology. Polyvinyl pyrrolidone (PVP) is used as a matrix to construct composite nanofibers containing different am

19. Etnomatemática de una Artesanía Argentina: identificando etnomodelos de trenzado
AbstractThis investigation focuses on the study of the mathematics of an Argentine craftsmanship of making braids. The objective is to develop a situated mathematical interpretation for the modeling of the braiding practice from an emic perspective. We set out from the reorganization of the space through the universal mathematical activities to locate and de

20. Frictional resistance of self-ligating versus conventional brackets in different bracket-archwire-angle combinations
Objective: To compare the influence of archwire material (NiTi, beta-Ti and stainless steel) and brackets design (self-ligating and conventional) on the frictional force resistance. Material and Methods: Two types of brackets (self-ligating brackets - Smartclip, 3M/Unitek - and conventional brackets - Gemini, 3M/Unitek) with three (0, 5, and 10 degrees) s

21. Effect of implant design and bone density in primary stability
AIM: To evaluate the influence of the format and surface treatment of implants, as well as the substrate used in primary stability. METHODS: Thirty-two Conexão® implants were used: 8 conical (CC) (11.5 x 3.5 mm) and 24 cylindrical (11.5 x 3.75 mm) - 8 external hexagon implants without surface treatment (MS), 8 external hexagon implants with double Porous t

22. Comparison of static friction with self-ligating, modified slot design and conventional brackets
OBJECTIVE: To compare the static frictional forces generated at the bracket/wire interface of stainless steel brackets with different geometries and angulations, combined with orthodontic wires of different diameters. MATERIAL AND METHODS: The frictional forces were evaluated with three different types of metal brackets: a passive self-ligating (SmartCl

23. Rutting analysis of 100 mm diameter polypropylene modified asphalt specimens using gyratory and Marshall compactors
Compaction technique used in Marshall design does not model the process of actual rolling procedures on site exactly. Carrying out laboratory compaction of dense bituminous mixtures with Superpave gyratory compactors is a more realistic way of simulating actual compaction. In this study, mechanical differences of reference and polypropylene modified asphalt

24. Aperfeiçoamento do emprego da equação universal de perda de solo na aplicação do pagamento por serviços ambientais da política espírito-santense de recursos hídricos
The mechanism of Payment for Environmental Services is a management tool in water resources policy of the state of Espírito Santo, which has the project Produtores de Água as part of this. This project is based on soil conservation for improvement/maintenance of water quality of streams and, therefore, offers financial compensation to those that preserve o
