(6) % 33.
In Group 1, the exposed dentin
surfaces were conditioned with GC cavity conditioner for a duration of 10 s, washed and air dried but not desiccated.
Dentinal hypersensitivity is characterized as a sharp pain of short duration which is arising from exposed dentin
surfaces in response to stimuli, typically thermal, evaporative, tactile, osmotic, chemical or electrical; and which cannot be attributed as any other dental disease.
Although fluoride ions may be released during the acid-base reaction, (11) the ability of these materials to cover exposed dentin
is their main mechanism that causes DH reduction.
It is also worth considering that high failure rates of ceramic laminate veneers have been related to large exposed dentin
Objective: Dentin desensitizing agents are used in the treatment of dentin hypersensitivity, which is defined as a painful response in the exposed dentin
to stimuli that are thermal, evaporative, tactile, osmotic, or chemical.
It is indicated for treatment of exposed dentin
, for use after prophylaxis or scaling and root planing, and before and/or after tooth bleaching.
Occluding agents act by physically covering or "plugging" the open, exposed dentin
tubules, thus preventing the effect of thermal changes or physical stimuli caused by the movement of dentin fluid resulting from pressure changes.
It contains patented NovaMin technology, which forms a toothlike layer over exposed dentin
to help continually repair and protect sensitive areas.
The exposed dentin
surfaces were sequentially polished with 240, 320, 450, and 600 grit sand paper.
Dentin hypersensitivity is defined as a short, sharp pain arising from exposed dentin
in response to stimuli, which cannot be ascribed to any other form of dental defect or pathology.
Recession itself is a condition that predisposes a person to root caries--cavities--due to decay of the exposed dentin
on the root of the tooth.
