BLOCKING SILICONE MATERIALS OF DENTINAL TUBES FOR DENTYPHICS.

摘要

A precipitated silica material that has an average particle size of 1 to 5 micrometers and that has an adduct present on at least a portion of its surface to form a precipitated silica material treated with adduct, wherein the precipitated silica material treated With adduct it exhibits a reduction of zeta potential greater than 10% compared to a precipitated silica material of the same structure in which the adduct is not present.
