It is indicated for treatment of exposed dentin
, for use after prophylaxis or scaling and root planing, and before and/or after tooth bleaching.
The independent, double-blind, clinical trial of 80 patients compares the enamel strengthening potential of Theodent(TM) toothpaste, containing Rennou(TM), to fluoride-based toothpastes by examining each product's ability to repair and re-mineralize exposed dentin
, which is the leading cause of tooth hypersensitivity.
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.
Currently, dentists etch the surface of the exposed dentin
with a mild acid, roughening it so the adhesive can fill the spaces.
So when stimuli such as hot or cold foods and beverages reach exposed dentin
, they cause the fluid in the dentinal tubules to move, which disturbs the nerve endings and results in sensitive teeth pain.
Unlike traditional veneers, participants will see how margin-free veneers can be used to close the bite and shield the exposed dentin
, while keeping original teeth intact.
When the exposed dentin
comes in contact with cold, sweet or acidic foods or drinks, the fluid in the dentinal tubules can move and irritate nerve endings, causing acute pain.
DHS is characterized by short sharp pain arising from exposed dentin
in response to stimuli typically thermal, tactile or chemical that cannot be ascribed to any other dental defect or disease.
These crystals occlude exposed dentin
tubules, thus alleviating hypersensitivity.
While there were numerous areas of exposed dentin
present, he was not experiencing dental pain.
17) This also makes the exposed dentin
more resistant to demineralization by acids.
