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 ...

The rôle of a dentine‐bonding agent in reducing cervical dentine sensitivity
Journal of Clinical Periodontology, 1998Abstract. This double‐blind split‐mouth trial with 16 adult patients investigated the ability of a dentine bonding agent (DBA) to reduce cervical dentine sensitivity. Following stimulation of pairs of teeth by conventional tactile and air blast stimuli, together with controlled evaporative and cold fluid stimuli, sensitivity was recorded using tactile

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 ...

The Dentin Disc Surface: A Plausible Model for Dentin Physiology and Dentin Sensitivity Evaluation
Advances in Dental Research, 1997Dentin sensitivity (DS) is a painful clinical condition which may affect 8-35% of the population. Various treatment modalities have claimed success in relieving DS, although at present there does not appear to be a universally accepted desensitizing agent.

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.

Journal of Clinical Periodontology, 1989
Abstract Studies of extracted teeth have shown that teeth exhibiting dentine hypersensitivity have larger numbers of widened dentinal tubules at the dentine surface compared to non‐sensitive teeth. Many compounds used in the treatment of dentine hypersensitivity are thought to achieve therapeutic benefit by tubule occlusion, but there has been almost ...

Sensitivity of dentin to chemical stimuli
Dental Traumatology, 1986Abstract Numerous chemical stimuli have been used to click pain from exposed dentin. Most of the effective chemicals share a common denominator; they arc all very hypertonic. Dentin surfaces covered with a smear layer are much less responsive to hypertonic solutions than dentin devoid of a smear layer. These observations support the hydrodynamic theory

To determine the effects of the iontophoretic application of lignocaine and epinephrine to exposed dentine on the sensitivity of the dentine in human subjects.The experiments were carried out on 13 healthy premolars (13 subjects) that were scheduled for extraction.
