Interstitial Fluid Pressure in Normal and Inflamed Pulp

摘要: Tissue pressure is the hydrostatic in interstitial fluid which surrounds pulpal cells. This outside vessels normally considerably lower than blood inside vessels. The dental pulp has a relatively low compliance due to its enclosure between rigid dentin walls. Accordingly, even modest increase volume will raise tissue pressure, may compress vessels, leading ischemia and necrosis. Inflammation lead an both low-compliant thereby pressure. However, increased may, turn, initiate lymph flow absorption of into capillaries nearby non-inflamed tissue. Both these latter factors transport out affected area subsequently tooth consequently Increased whether caused by or capillary filtration, promote outward through exposed tubules help protect against entry harmful substances. It seems physiologically beneficial, therefore, for have high promptly increases when compliance.
