Dentin hypersensitivity (DH) is triggered by external stimuli irking fluid flow through exposed dentinal tubules (DTs). Three commercially available desensitizing agents as control in this study only achieve limited occlusion depths of ≈10 µm in the DTs ...

Fluid flow through human dentine
Archives of Oral Biology, 1967Abstract With freshly extracted sound teeth it has been shown that a saturated solution of CaCl2 at 37 °C causes fluid movement through dentine when applied to a small occlusal cavity. Measurement of the rate of flow was made photographically and the maximum value obtained in a group of eight teeth was 4.8 nl/sec.

Fluid movement in human dentine
Archives of Oral Biology, 1965Abstract To investigate fluid movement in dentine and a possible relationship between this movement and odontoblast aspiration, a chamber was designed which allowed microscopic observation of an exposed dentine surface, in vitro, while this surface was being subjected to reduced pressure.

Fluid flow through cat dentine in vivo
Archives of Oral Biology, 1992An outward flow of fluid through exposed dentine was demonstrated in anaesthetized cats. The flow was measured by observing the movement of the fat droplets of dilute milk in a glass capillary (i.d. 30 microns) with a microscope. The capillary was sealed to the dentine with a plastic cap.

In-vivo fluid movement across dentine in the dog
Archives of Oral Biology, 1981Abstract Conical chambers were cemented to dentine and connected via micropipettes to a pressure bottle to permit measurement of the rate of fluid movement across dentine under positive or negative hydrostatic pressures. Connecting the chamber to a pressure transducer permitted measurement of intra-pulpal tissue pressure through intact dentine, which

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.

Odontoblast aspiration and fluid movement in human dentine
Archives of Oral Biology, 1967Abstract To investigate further a possible relationship between odontoblast aspiration and fluid movement in dentine, axial coronal dentine was exposed by disk cut and fracture and subjected to reduced pressure in vitro . Sections showed that odontoblast aspiration had occurred into dentine, the peripheral part of which had been exposed by fracture,

Regional resistances to fluid flow in human dentine in vitro
Archives of Oral Biology, 1978Abstract 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 ...
