Permeability of dentine.

open access: yesThe Malaysian journal of medical sciences : MJMS, 2013
This is an update on the present integrated knowledge regarding dentine permeability that assumed a role in dentine sensitivity and contribute clinically to the effective bonding properties of restorative dental materials. This paper will attempt to refer to in vivo and in vitro studies of dentine permeability and the various interrelated factors ...

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, Volume 7, Issue 3, June 2026.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Effect of experimental dentifrices containing epigallocatechin-3-gallate–loaded chitosan nanoparticles on permeability, tubule occlusion, microhardness, and wear in eroded dentinWhy Is This Important?

open access: yesJADA Foundational Science
Background: Dentin hypersensitivity and tooth wear are common oral conditions. Natural substances and nanotechnology emerge as promising approaches. This study aimed to evaluate the effect of experimental dentifrices containing epigallocatechin-3-gallate

Effect of adhesive system and application strategy on reduction of dentin permeability

open access: yesBrazilian Oral Research, 2012
This study evaluated the effect of adhesive systems and application strategies on dentin hydraulic conductance (HC). The buccal enamel was removed from bovine incisors to simulate laminate cavity preparations.

Evaluation of the dentin changes in teeth subjected to endodontic treatment and photodynamic therapy

open access: yesRevista de Odontologia da UNESP
Introduction Antimicrobial photodynamic therapy (PDT) is an efficient adjuvant technique to promote disinfection of the root canal system. Therefore, it is important to investigate changes to dentin morphology and permeability induced by the use of diode

Comparison of dentinal hydraulic conductance according to the application time of oxalate-based desensitizers

open access: yesRevista Facultad de Odontología Universidad de Antioquia, 2015
Introduction: an in vitro model was used to measure the hydraulic conductance in human dentin discs treated with oxalic acid for 15, 30 or 60 s maintaining the occlusive effect and measuring 7 and 14 days after application.
