The Hydrodynamic Theory of Dentinal HypersensitivityThe predominant theory of DH states that pulpal sensitivity is mediated by a "hydrodynamic mechanism".1,13-17 A stimulus(thermal, mechanical, evaporative or osmotic/chemical) applied to dentin can increase the flow of dentinal tubular fluid within th...
velocity–pressure coupling; low-Reynolds-number flow; SOR method; staggered grids; electro-osmotic flow Abstract In this study we developed simple, coupled algorithms for solving low-Reynolds-number flows applicable to micro-scale flows such as electro-osmotic flows. The most popular scheme, i.e....
The push-pull osmotic pump has been developed for zero order delivery of lithium carbonate for a period of 24h. The effect of various formulation variables on bilayer core tablet and its semi permeable coating along with orifice diameter have been investigated and optimized for desired drug release...
(Fig. 1) When dentinal tubule smear plugs are lost, the hydraulic conductance increases a whopping 32-fold,25,27 resulting in potential for intense dentinal hypersensitivity. (Fig. 2)by Rod KurthyD.M.D
Reverse osmosis is a separation process where solvents are passed through a semipermeable membrane while solutes are retained by applying a pressure higher than the osmotic pressure. Rodriguez et al. [132] discovered that RO and forward osmosis (FO) are generally very effective in removing endocrine...
