What is hypersensitivity theory?
The theory states that dentine hypersensitivity is caused by movement of the dentinal tubule contents. Various stimuli alter the flow and pressure of the tubule fluid and thus by hydrodynamic action these changes are detected by the mechanoreceptors surrounding the odontoblast processes.
What is dentine hypersensitivity?
Dentine hypersensitivity has been defined as pain arising from exposed dentine, typically in response to chemical, thermal, tactile or osmotic stimuli that cannot be explained as arising from any other form of dental defect or disease [8].
What causes dentin hypersensitivity?
Dentin hypersensitivity arises when tubules found within dentin become exposed, most commonly caused by gingival recession or enamel wear. Once exposed, these tubules may come into contact with stimuli such as hot, cold and sweet foods and drinks, which can induce the movement of fluid within the tubules.
Which is the most accepted theory of dentin hypersensitivity?
Hydrodynamic Theory for sensitive dentine was first proposed by Brannstorm [21]. This theory is the most widely accepted theory for DH. The theory has been proposed based on the movement of the fluid inside the dentinal tubules.
What is the most widely accepted theory to explain dentin hypersensitivity?
The Hydrodynamic Theory Of Dentin Hypersensitivity Brännström’s hydrodynamic theory is currently the most commonly accepted theory of how dentin hypersensitivity arises: Dentin hypersensitivity arises when tubules found within dentin become exposed, most commonly caused by gingival recession or enamel wear.
Can dentin hypersensitivity be cured?
They may not realize it, but patients with dentinal hypersensitivity don’t have to resign themselves to living with the problem. The most common first-line treatment for reducing pain is over-the-counter potassium nitrate dentifrice, which aims to desensitize the teeth by reducing nerve excitability.
Is dentin hypersensitivity serious?
Prognosis. Dentin hypersensitivity may affect individuals’ quality of life. Over time, the dentin-pulp complex may adapt to the decreased insulation by laying down tertiary dentin, thereby increasing the thickness between the pulp and the exposed dentin surface and lessening the symptoms of hypersensitivity.
What causes dentine sensitivity?
Dentine hypersensitivity arises when tubules found within dentine become exposed, most commonly caused by gingival recession or enamel wear. Once exposed, these tubules may come into contact with stimuli, which can induce the movement of fluid within the tubules.
What is the hydrodynamic theory of dentinal hypersensitivity?
The hydrodynamic theory of dentinal hypersensitivity states that noxious stimuli at open dentinal tubules cause movement of fluid within the tubules and irritation of the odontoblasts and intradental nerves.
What are the best strategies for dentinal hypersensitivity management?
Strategies for Dentinal Hypersensitivity Management 1 Arginine and calcium carbonate. When arginine is combined with a bicarbonate buffer… 2 Calcium sodium phosphosilicate. These minerals deposit within dentinal tubules,… 3 Stannous fluoride and sodium fluoride. The relief provided by these agents may be due… 4 A recent systematic…
What is dentinal hypersensitivity in dogs?
Abstract Dentinal hypersensitivity (DH) is a common clinical condition usually associated with exposed dentinal surfaces. It can affect patients of any age group and most commonly affects the canines and premolars of both the arches. This article concisely reviews the patho-physiology, mechanism and clinical management of the DH.
