Dentin hypersensitivity can be a major problem for periodontal patients. The relationship between dentin hypersensitivity and the patency of dentin tubules in vivo has been established. Thirteen adult patients with teeth scheduled for extraction were selected and a stent fabricated to confirm location of the root surface being examined.

Abstract A series of experiments have been conducted to examine the manner in which the removal of dentinal fluid can give rise to pain. Histologic examination and theoretical calculations indicate that at the same time there is a rapid outward flow in the dentinal tubules as a result of capillary forces.

Mechanisms of Dentin Sensitivity
Dental Clinics of North America, 1990This article reviews dentin sensitivity from a mechanistic perspective beginning with short treatments of pulpal innervation, the hydrodynamic considerations of dentin, and how various stimuli may cause pain. Speculation is raised about the contribution of bacteria and their products on dentin sensitivity and how dentin might become truly ...

Abstract Based on the hydrodynamic theory for stimulus transmission across dentine, it would be logical to conclude that teeth exhibiting the clinical symptoms referred to as dentine hypersensitivity should have dentinal tubules open at the root surface and patent to the pulp.

The effects of primers on the sensitivity of dentin
Dental Materials, 1991The effects of dentin primers on the sensitivity of dentin were examined by measurement of the repetitive firing observed when a class V cavity prepared in the dentin of the lower jaw of a rabbit was irritated by a blast of compressed air. It was possible to conclude that the combined application of an aqueous solution of 35% hydroxyethyl methacrylate ...

Hypothetic mechanisms for dentine sensitivity
Oral Surgery, Oral Medicine, Oral Pathology, 1971Abstract It is well known that the drilling of teeth and the subjection of exposed dentine to thermal, chemical, electrical, or tactile stimuli elicit painful reactions. After an examination of various hypotheses, it is obvious that complete knowledge and understanding of the mechanism underlying dentine sensitivity are yet to be attained and that ...

Thermal stimuli in dentinal sensitivity
Dental Traumatology, 1986Abstract Current thinking on thermal stimuli and dentinal sensitivity are reviewed in this manuscript. There are two schools of thought: 1) following the Hydrodynamic Theory, thermal stimuli evoke dentinal sensitivity by changing physical properties of the dentin, namely, tubular radius and dentinal fluid viscosity, and 2) thermal stimuli evoke ...

Dentin sensitivity and aspiration of odontoblasts
The Journal of the American Dental Association, 1963The aspiration of odontoblasts into the dentinal tubules as an immediate effect of physical stimuli applied to exposed dentin seems to result from loss of sub stance at the distal apertures of the tubules and subsequent outward flow of the tubular contents through capillary action.

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.
