J. appl. oral sci; 26 (), 2018
Abstract Objectives To determine the concentration of calcium, iron, manganese and zinc ions after the application of chelator to Enterococcus faecalis biofilms. Material and Methods Fifty bovine maxillary central incisors were prepared and inoculated with E. faecalis for 60 days. The following were ...

Determination of residual parachloroaniline produced by endodontic treatment after the use of 5% sodium hypochlorite and 2% chlorhexidine combined: an ex-vivo study

ABSTRACT: Aim: The objective of this work was to determine the concentrations of irrigating solutions and the residual content of parachloroaniline (PCA) formed after endodontic irrigation, using 5% NaOCl, 0.9% NaCl, 10% EDTA and 2% CHX 2%. Methodology Twenty premolars were used and 13 samples were col...

Métodos: blocos de dentina bovina estéreis foram inseridos em um dispositivo intrabucal, o qual foi utiliz...

Effect of two desensitizing agents on dentin permeability in vitro

J. appl. oral sci; 25 (1), 2017
Abstract Objective The aim of this in vitro study was to investigate the effect of two desensitizing agents and water on hydraulic conductance in human dentin. Material and Methods GLUMA Desensitizer PowerGel (GLU) contains glutaraldehyde (GA) and 2-hydroxyethyl methacrylate (HEMA), and Teethmate Des...

Effects of different irrigation regimes in physico-chemical properties of dentin and consequences of changes in the adhesion of microorganisms and AH Plus sealer

Besides of the desired effects, the chemical solutions used to assist the endodontic instruments in the cleanliness and disinfection of the root canal system can also cause changes in the physicochemical properties of dentin, and consequently affect the adhesion of endodontic sealers and microorganisms t...

Influência do ressecamento da superfície radicular, do tratamento com EDTA e ácido Hialurônico na viabilidade e expressão de citocinas inflamatórias de fibroblastos do ligamento periodontal

O momento ideal para o reimplante de um dente avulsionado é imediatamente após a avulsão, no entanto, isso nem sempre é possível. Uma série de fatores influenciam na viabilidade das células do ligamento periodontal (PDL) contribuindo para acelerar ou minimizar a ocorrência da reabsorção radicul...

Efetividade de soluções endodônticas na redução da viabilidade de Enterococcus faecalis cultivados em forma séssil e planctônica

Este estudo teve como objetivo avaliar a sensibilidade dos biofilmes de E. faecalis a NaOCl, CHX e PAA após uma exposição de ácido cítrico 2,5%. O biofilme de E. faecalis foi formado em lamínulas de vidro circular de 13 mm Ø em placas de cultura de 24 poços. Os biofilmes foram tratados ou não du...

Influence of root dentin treatment on the push-out bond strength of fibre-reinforced posts

Abstract This study evaluates the influence of root dentin treatment with NaOCl alone and combined with EDTA, with and without ultrasound activation, on the push-out bond strength (BS) of fiber-reinforced posts in weakened roots, cemented with RelyX or Panavia. The root canals of 42 maxillary canines wer...
