Dentin permeability and dentin sensitivity.
Proceedings of the Finnish Dental Society. Suomen Hammaslaakariseuran toimituksia, 1992 The 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.

An In Vivo Study of Dentin Sensitivity: The Relation of Dentin Sensitivity and the Patency of Dentin Tubules [PDF]
Journal of Periodontology, 1991 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 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.

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.

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 ...

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 ...

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 ...

Diagnosis and management of dentine sensitivity [PDF]
Dental Nursing, 2013 The aim of this article is to update dental nurses on dentine sensitivity—a perplexing clinical condition that is not fully appreciated by many clinicians and may not only under diagnosed but unsuccessfully managed in dental practice

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 ...

Dentine sensitivity: Past, present and future
Journal of Dentistry, 2013This review defines dentine sensitivity (DS), its prevalence, its aetiology, the mechanism(s) responsible for DS, its diagnosis and its treatment. The review then examines the modes of action of various treatments for DS including potassium salts, strontium salts, bioglasses, arginine/calcium carbonate and professional treatments such as adhesives and ...
