摘要

System for measuring dentin permeability and method for simulation of the pressure intrapulpar using said system. Describes a system to be used in the measurement of the dentin permeability and a method to simulate the pressure intrapulpar a human tooth is affected using the said system.Said system is comprised by a regulator (1) connected to a pressure of compressed air system.A hose (2) which has one of its ends connected to the regulator (1) pressure and the other end of the hose (2) is connected to a camera (3) and pressure in the chamber (3) pressure be linked has one end of a second hose (4), and the other end the di... TA hose (4) being connected to a pressure gauge (5) of precision and the camera (3) pressure be connected even U.One of the ends of a tube (6) of copper, and the other end of said tube (6) of copper being connected in a device (7) for the injection of bubble; and the said device (7) for injection of bubble being connected in a capillary tube (8) which is connected in a test chamber (9). Said system can also be used to measure the quantity of liquid which passes through the dentinal tubules in the dentin.
