Effect of dentin conditioning on dentin permeability and micro‐shear bond strength
European Journal of Oral Sciences, 2007The purpose of this study was to compare fluid flow rates across dentin surfaces treated with four conditioners. The effect of conditioning on the micro‐shear bond strengths of glass ionomer cement (Fuji IX GP) and resin‐based adhesives (Single Bond 2 or Clearfil SE Bond) were also investigated.

Dentin permeability and dentin sensitivity.
Proceedings of the Finnish Dental Society. Suomen Hammaslaakariseuran toimituksia, 1992The hydrodynamic theory of dentin sensitivity is based on the premise that sensitive dentin is permeable throughout the length of the tubules. Such a condition may permit the diffusion of bacterial products across dentin to the pulp where they may cause irritation of pulpal soft tissues.

Dentin permeability: sealing the dentin in crown preparations.
Operative dentistry, 1992Provisional restorations of full crown preparations may permit more microleakage of bacteria and their products than the final castings do. However, most investigations of the sealing qualities of cemented castings have reported that they too permit dye leakage.

Dentinal Permeability in Assessing Therapeutic Agents
Dental Clinics of North America, 1990The measurement of dentinal permeability has been useful in confirming the mechanism of the hydrodynamic hypothesis for pain transmission in hypersensitive patients, has advanced our understanding of how neural agents can reach the pulpal nerves, and has provided useful data to compare and evaluate therapeutic agents.

Effect of dentin desensitizers and dentin bonding agents on dentin permeability.
American journal of dentistry, 2002To determine the effect of dentin desensitizing agents (oxalates and glutaraldehyde) and dentin bonding agents, with and without resin-based composite (RBC) on dentin permeability and morphology of the dentin surface. The influence of saliva and toothbrushing on these agents was also evaluated.Radicular dentin discs +/-1 mm thick were obtained from ...

Dentin permeability: Self-etching and one-bottle dentin bonding systems
The Journal of Prosthetic Dentistry, 2003There 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 ...

Dentin permeability, dentin sensitivity, and treatment through tubule occlusion
Journal of Endodontics, 1986The 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.

[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 ...

[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

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 ...
