PEREZ RUIZ, Andrés; CABRERA DURANZA, Manuel  e  SANTOS RODRIGUEZ, Pablo E.. Hipótesis actuales relacionadas con la sensibilidad dentinal. Rev Cubana Estomatol [online]. 1999, vol.36, n.2, pp. 171-175. ISSN 1561-297X.

A review of the present hypotheses of dentinal sensitivity was carried out. The analysis was centered on the theories of the existance of nerves in dentin, the transfer of nervous impulse through odontoblast and the fluid flow in the dentin. Since the explanation of dentin sensitivity is one of the most complex problems of dental physiology and histology; the morphological and functional aspects that support the validity of the mentioned mechanisms are stated. It is concluded that although the hydrodynamic theory has a sound experimental basis and is widely accepted at present, more than one of these likely theories could be involved in the genesis of dentinal pain.
