Dentine hypersensitivity: the measurement in vitro of streaming potentials with fluid flow across dentine and hydroxyapatite

Journal of Periodontal Research, 1993
Stimulus transmission across dentine, in conditions such as dentine hypersensitivity, is considered to occur via a hydrodynamic mechanism. This fluid flow in dentine may then induce a mechanoreceptor response in pulpal nerves. However, when fluid flows through a porous structure electrical potentials are also generated.

Regional resistances to fluid flow in human dentine in vitro

Archives of Oral Biology, 1978
Abstract The resistance to fluid movement through dentine was analysed in terms of 3 resistances placed in series: (1) surface resistance due to the presence of debris occluding dentinal tubules, (2) an intratubular resistance due to mineralized nodules and internal irregularities within the tubules, (3) a pulpal resistance due to the presence of ...

Fluid Movement across the Resin-Dentin Interface during and after Bonding

Journal of Dental Research, 2004
This study evaluated the extent of water penetration through resin-dentin interfaces before and after being sealed with adhesives. Four adhesive resin systems (2 total-etch adhesives and 2 self-etching primer adhesives) were used in this study. Dentin disks were placed in a split-chamber device, and in situ fluid movement across dentin was measured ...

In vivo Fluid Movement through Dentin Adhesives in Endodontically Treated Teeth

Journal of Dental Research, 2005
Fluid transudation through simplified dentin adhesives can occur in bonded vital crown dentin, since these adhesives behave as permeable membranes after polymerization. The effect of adhesive permeability in endodontically treated teeth is unknown. This study examined the hypothesis that in vivo fluid movement through simplified adhesives occurs when ...

[Effect of phenolic resin fluid on the dentin resistance].

Zhonghua kou qiang yi xue za zhi = Zhonghua kouqiang yixue zazhi = Chinese journal of stomatology, 1991
SEM observation was made in the experiment to analyze the ultrastructure of resinified dentin. Phenolic resin fluid permeates in to the dentinal-tubule and set in it. The permeability of this agent was also able to permeate into intercellular substance and changed the appearance of inter-weaved fibril to the condition of agent had set. According to the
