[Microbial permeability of dentin].
Stomatologia, 1990This is a review of the literature about the contemporary aspects of microbial permeability of dentin. They are discussed the factors that are responsible for this question and analytically: the structure of dentin, the composition of dentin in organic and inorganic ingredients, the response mechanisms of dentin, that is the irritation dentin and ...

Dentin permeability after toothbrushing with different toothpastes.
American journal of dentistry, 1999To evaluate the interaction of smear layer produced during brushing and dentifrice particles.Dentin disks were obtained from extracted human third molars. Dentin permeability was evaluated using a hydraulic pressure apparatus working at 1 psi of pressure.

Dentinal Tubule Occlusion and Dentin Permeability Efficacy of Silver Diamine Fluoride Solutions
International Journal of Dental HygieneABSTRACTAimThis in vitro study compared the effect of two commercially available silver diamine fluoride (SDF) products on dentinal tubule (DT) occlusion and dentin permeability.MethodsSixty‐six dentin discs (1.0 mm thick) were divided equally into six groups: acid‐etched with no treatment (negative control—NC), etched and sealed with nail varnish ...

Dentin permeability. The clinical ramifications.
Dental clinics of North America, 1992Dentin is a unique material with the ability to provide not only sensation to the pulp but protection of this soft tissue. The jury is still out concerning the practice of etching dentin with caustic substances in order to remove the smear layer and to open dentinal tubules prior to restorative procedures.

[Effect of various pretreatments for dentin bonding on dentin permeability].
Shika zairyo, kikai = Journal of the Japanese Society for Dental Materials and Devices, 1992Pretreatment of the dentinal surface with acidic solution is now considered to be necessary to obtain strong bonding between dentin and resin materials. Effects of various surface treatments for dentin bonding on dentinal smear removal have been reported by SEM observation. In this study, changes of dentin permeability after the surface treatments were

Bleaching technique effect on dentin permeability.
American journal of dentistry, 2014To evaluate the effect of bleaching techniques on dentin permeability. The hypothesis was that the bleaching agent associated or not to etching and/or energy source would be able to increase dentin permeability (conductance).Fifty 1 mm-thick disks of mid-coronal dentin were obtained from human third molars, which were mounted in a filtration chamber ...

Permeability of dentin to adhesive agents.
Quintessence international (Berlin, Germany : 1985), 1994The permeability of dentin to adhesive agents is of crucial importance in obtaining good dentinal bonding. In those systems that remove the smear layer, the opportunity exists for resin to infiltrate both tubules and intertubular dentin. Resin penetration into tubules can effectively seal the tubules and can contribute to bond strength if the resin ...

Dentin permeability: effects of crown preparation.
The International journal of prosthodontics, 1992Sequential crown reductions of extracted human teeth were made to evaluate both regional differences in dentin permeability and the effects of tooth reduction. Two different methods of tooth reduction were used. In group 1, tooth reduction was nonuniform but was done in a manner similar to conventional crown preparations.
