CHX stabilizes the resin/demineralized dentin interface

Braz. dent. j; 32 (4), 2021
Abstract The aim of this study was to evaluate the effect of 2% chlorhexidine digluconate (CHX) on microtensile bond strength (µTBS) between an adhesive system and under 3 dentin conditions. For that, this study evaluated the adhesive interface at initial, after 6 months and 1 year of storage. Forty-eig...

The influence of ischemic preconditioning on neuromuscular performance

Rev. bras. med. esporte; 27 (2), 2021
ABSTRACT Introduction: Ischemic preconditioning (IPC) has been described in the literature as a resource capable of improving physical performance. Objective: The purpose of this randomized double-blind study was to evaluate the influence of IPC on the neuromuscular performance of trained individuals. ...

Estudio comparativo entre coronas, endocoronas y endocoronas con ausencia de una pared axial ante fuerzas de tracción
Comparative study between crown, endocrown and endocrown without one axial wall after tensile strength

Rev. ADM; 78 (3), 2021
Introducción: Las alternativas de tratamiento de órganos dentales con gran destrucción en su estructura varían, no sólo por el material de restauración, sino también por el valor económico y estético. Dentro de las alternativas existe: corona convencional, endocorona cuyo objetivo principal es l...

Evaluation of tensile strength after insertions andremovals of abutments on frictional Morse taper implants

This study aimed to evaluate possible changes in final retention after nine sequences of insertion and removal (SIR) of a frictional Morse taper implant/abutment system, evaluating the force required for dissociating this set between sequences, and verifying possible deformations in the implant heads. Te...

Efeito do envelhecimento hidrotérmico e mecânico na performance à fadiga de zircônias de alta translucidez

O objetivo deste trabalho foi avaliar a resistência à fadiga e ciclos até a falha de 3 zircônias odontológicas após envelhecimento hidrotérmico isolado e um novo protocolo alternado. Discos de zircônia “Y”Z T (VITA), INCORIS “T”ZI (Dentsply Sirona) e “K”ATANA UTML (Noritake Kuraray) (...

Development of electrospun-based polyetherimide fibers and diameter analysis for potential use in dental materials

Braz. dent. sci; 24 (2), 2021
Objetives: this study aimed to fabricate electrospun-based polyetherimide (PEI) fibers, under controlled parameters, and to perform a diameter analysis for potential mechanical improvement of dental materials. Material and Methods: PEI pallets (0.75 g) were dissolved in 2...

Analytic Hierarchy Process Algorithm Applied to Battery Energy Storage System Selection for Grid Applications

Braz. arch. biol. technol; 64 (spe), 2021
Abstract The Brazilian Power Sector is preparing the introduction of battery energy storage in its distribution lines for energy quality control. The technical and financial viability of this new technology depends on several factors: battery technologies, geographical locations, environmental restrictio...

Resistencia adhesiva de postes de fibra a los diferentes tercios del conducto radicular
Adhesive resistance of fiber posts to different thirds of the root canal

En los últimos años resulta de elección la utilización de postes de fib ra en la rehabilitación de piezas endodónticamente tratadas. La adhesión entre poste, agente cementante y dentina radicular permitiría lograr una retención de la estructura dentro de las paredes del conducto. El objetivo de ...

Biological and mechanical characterization of commercial and experimental periodontal surgical dressings

Abstract The objective of this study was to evaluate the biocompatibility and mechanical properties of two commercially available and one experimental periodontal dressing materials. The cytotoxicity of Periobond ® , Barricaid ® and one experimental periodontal dressing based on Exothane ® 8 monomer w...

A Modified Flexor Tendon Suture Technique Combining Kessler and Loop Lock Flexor Tendon Sutures

Clinics; 76 (), 2021
OBJECTIVES: In the present study, a novel single knot tenorrhaphy was developed by combining the modified Kessler flexor tendon suture (MK) with the loop lock technique. METHODS: A total of 48 porcine flexor digitorum profundus tendons were collected and randomly divided into six groups. The tendons wer...
