Effect of Application of Natural versus Synthetic Desensitizing Agents on Dentin Permeability

Al-Azhar Dental Journal for Girls, 2021
Purpose: This in vitro study was established to compare the effect of natural versus synthetic desensitizing agents on dentin permeability. Materials and Methods: Class V cavity preparation was done on the labial surface of 40 premolars for cervical ...

The relationship between dentin bond strengths and dentin permeability

Dental Materials, 1989
The relationship between dentin permeability and the shear bond strength of Scotchbond/Silux was investigated. In the presence of a smear layer, there was no correlation between dentin permeability and dentin bond strengths. After removal of the smear layer with acids, there was an inverse relationship between dentin permeability and dentin bond ...

Dentin Permeability: Determinants of Hydraulic Conductance

Journal of Dental Research, 1978
A technique is described which permits measurement of the ease with which fluid permeates dentin. This value, the hydraulic conductance of dentin, increased as surface area increases and/or as dentin thickness decreases. It increased 32-fold when dentin was acid etched due to removal of surface debris occluding the tubules.

Permeability of normal versus carious dentin

Dental Traumatology, 1991
Abstract Although a number of reports have been published demonstrating that carious dentin is less permeable than normal dentin, these reports have been qualitative rather than quantitative. The purpose of this in vitro study was to apply a quantitative technique to the study of the permeability of carious human teeth before and after excavation ...

Permeability of demineralized dentin to HEMA

Dental Materials, 2000
The objectives of this study were to develop a macromodel of the demineralized layer of dentin that is formed after acid-etching, and to determine if the amount of HEMA uptake was responsive to air drying. The hypothesis that was tested was that HEMA uptake by demineralized dentin depends upon the degree of expansion of the collagen fibril network ...

Effect of Dycal® on dentin permeability

Dental Traumatology, 1988
Abstract The ability of 3 formulations of a hard‐setting calcium hydroxide‐containng base material (Dycal®) to seal dentinal tubules was evaluated in an in vitro model. The latest light‐cured generation of the material was clearly superior to the previous formulations at all time periods tested.

Dentin permeability and tubule occlusion of dentin treated with NaF and TiF4 varnishes compared to Elmex Opti-namel and Biomin F toothpastes under simulated pulp pressure.

E -journal of dentistry
OBJECTIVES To investigate if a NaF varnish, a TiF4 varnish, a SnCl2+chitosan+amine fluoride/NaF toothpaste (Elmex Opti-namel) and a fluoride-calcium-phospho-silicate glass-containing toothpaste (Biomin F) reduce dentin permeability after treatment and ...

Dentin permeability: Self-etching and one-bottle dentin bonding systems

The Journal of Prosthetic Dentistry, 2003
There are many bonding systems available, with or without a prior acid etch. The mechanisms differ from system to system. Therefore it is important that the clinician know which are the most effective and which provide the best seal.This study measured the infiltration of physiological saline solution across dentin after application of self-etching or ...

Influence of Phosphoric, Glycolic, and Ferulic Acids on Dentin Enzymatic Degradation, Ultimate Tensile Strength, and Permeability.

Operative dentistry, 2023
This study evaluated dentin enzymatic degradation based on the total matrix metalloproteinase (MMP) activity of demineralized dentin matrices before and after exposure to phosphoric acid (PA), glycolic acid (GA), and ferulic acid (FA).

Dentin permeability, dentin sensitivity, and treatment through tubule occlusion

Journal of Endodontics, 1986
The hydrodynamic theory of dentin sensitivity states that movement of tubule contents or tubule fluid, in either direction, causes dentin sensitivity. A corollary of that theory is that anything that can decrease dentinal fluid movement or dentin permeability should decrease dentin sensitivity.
