Effect Of Various Solutions To Exudation Of Internal Fluids From Dentinal Tubules

Effect of various solutions to the exudation of internal fluids from dentinal tubules on cut dentin surfaces was observed by SEM using precision replica technique. Labial enamel of freshly extracted bovine teeth was removed and dentin surfaces were exposed. The right half of these surfaces was treated with various solutions. These treated surfaces were immediately impressed with silicone impression material. Epoxy resin was poured into these impressions. Precision replicas were coated with platinum and observed by SEM. Exudation of internal fluids from dentinal tubules was observed on the Super bond D liner-treated dentin surfaces. Exudation was slightly observed on the 21% K2C2O4 + 3% KHC2O4 and 15.5% Fe-2(SO4)(3)-treated dentin surfaces. Exudation was not observed on the Super bond D primer + D liner and Clearfil LB primer-treated dentin surfaces. Round crystal was observed on the Ag(NH3)(2)F-treated dentin surfaces. 21% K2C2O4+3% KHC2O4, 15.5% Fe-2(SO4)(3), Super bond D liner primer + D liner and Clearfil LB Primer were effective to stop the exudation of internal fluids from dentinal tubules.
