Effects of two disinfection/sterilization methods for dentin specimens on dentin permeability

Clinical Oral Investigations, 2018
To investigate the effects of two disinfection/sterilization methods on the permeability of dentin specimens.Forty intact human third molars were freshly extracted and cut, close to the pulp chamber, into dentin disks with a 500-μm thickness. The disks were randomized (n = 20 each) into a 70% ethanol group (acid-etched dentin disks soaked in 70 ...

Dentine permeability and tracer tests

Journal of Dentistry, 1999
This paper reviews the evidence for dentine's permeability in order to clarify and emphasize its confounding effect on leakage test measurements, and hence the need to use special test designs to avoid its effects.The literature on the subject between 1887 and 1997, including 249 articles.The prerequisite condition for any tracer penetration test is ...

Effect of bioactive glasses containing strontium and potassium on dentin permeability.

Journal of Biomedical Materials Research. Part B - Applied biomaterials, 2021
Dentin hypersensitivity (DH) is characterized by pain caused by an external stimulus on exposed dentin. Different therapeutic approaches have been proposed to mitigate this problem; however, none of them provide permanent pain relief.

Dentine permeability and dentine adhesion

Journal of Dentistry, 1997
The objectives of this paper are to review the structure of dentine as it pertains to adhesive bonding and to describe the importance of resin permeation into dentinal tubules and into spaces created between collagen fibrils by acid-etching during resin bonding.

Dentin Permeability and Nanoleakage of Universal Adhesives in Etch-and-rinse vs Self-etch Modes.

Operative dentistry, 2021
CLINICAL RELEVANCE Universal adhesives do not seem to have the ability to effectively seal dentin, regardless of the mode of application. SUMMARY Purpose: This study evaluates the reduction in dentin permeability (P) and the expression of nanoleakage ...

Physicochemical characterization, water sorption and solubility of adhesive systems incorporated with titanium tetrafluoride, and its influence on dentin permeability.

Journal of The Mechanical Behavior of Biomedical Materials, 2021
Titanium tetrafluoride (TiF4) in an aqueous solution can decrease dentin permeability, but some effects of its incorporation into adhesive systems are not yet known. Therefore, the aim of this study was to characterize the physicochemical, water sorption

Dentin permeability of carious primary teeth

Nigerian Journal of Clinical Practice, 2017
Many in vitro studies have used dentine permeability to evaluate the efficacy of various restorative and preventative procedures. The easiest way to evaluate dentine permeability is to calculate its hydraulic conductance (Lp) using fluid filtration methods.
