(1990) Clinical study on the treatment of
hypersensitive dentin by GaAlAs laser diode using double blind test.
For crown preparations, thin-film coating materials have been developed based on all-in-one adhesive technology for sealing of crown preparations and desensitizing
hypersensitive dentin. The coating materials improve the performance of the resin cement and prevent leakage beneath the crown.

hypersensitive dentin," The Journal of the American Dental Association, vol.
(2-4) It has been demonstrated that
hypersensitive dentin has a larger number of wide, opened dentinal tubules on the surface than does non-sensitive dentin.
To overcome the enigma of hypersensitive dentin several possible approaches have been proposed such as:
Old remedies and materials since decades used for management of hypersensitive dentin includes use of lung ash from mice, dried livers from lizards and salt lavage, potassium nitrate, alum, anodynes such as cocaine hydrochloride, clove oil, menthol, phenol, eugenol morphine sulfate or codeine sulfate.
This interference in the polarity of cell membranes by increasing the amplitude of the action potential of cell membranes can block the transmission of pain stimuli in
hypersensitive dentin. (14)
