A novel application of nano eggshell/titanium dioxide composite on occluding dentine tubules: an in vitro study

Abstract To synthesize Nano eggshell-titanium-dioxide (EB@TiO2) biocomposite and to evaluate its effectiveness in occluding opened dentine tubules. EB@TiO2 was synthesized and characterized using X-ray diffraction (XRD), and Transmission Electron Microscope (TEM). Sixteen simulated bovine dentine discs w...

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 desensitizing treatments on root dentin permeability

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to evaluate the effects of diode laser and a desensitizing dentifrice on dentin permeability. Fifty-two root dentin fragments were obtained (5 × 5mm) and treated with 24% EDTA gel. The samples were divided into 4 groups (n = 13): G1, control (no treatment); G2, d...

Efeito de agentes anti-hiperestésicos à base de oxalato de potássio na permeabilidade da dentina humana: estudo in vitro

O oxalato de potássio tem sido utilizado no tratamento da hiperestesia dentinária através da precipitaçäo de cristais de oxalato de cálcio intra e extracanaliculares, obstruindo os túbulos dentinários e reduzindo o deslocamento de fluido. O objetivo desse estudo foi analisar in vitro quantitativa...

Estudo "in vitro" da permeabilidade dentinária após a aplicação de agentes clareadores
\"In vitro\" study of dentin permeability after application of clarifying agents

Rev. paul. odontol; 14 (4), 1992
Os autores estudaram a ação dos agentes clareadores, mistura de perborato de sódio + peróxido de hidrogênio a 30 por cento com e sem aplicação de calor, sobre a permeabilidade dentinária. A permeabilidade da dentina foi detectada por meio de infiltração de íons cobre e quantificada pela análi...
