Abstract：
:Forty freshly extracted human teeth were biomechanically prepared for endodontic obturation using a radioisotopically labeled EDTA-urea peroxide-Carbowax compound. The amount of radiolabeled mixture remaining in the canals after through cleansing was about 3.8% of that originally applied. The amount of residue did not decrease with reinstrumentation and irrigation.

杂志文章abstract：INTRODUCTION:Pulp capping materials allow healing of injured pulp with a layer of reparative dentin. Glucose is needed to cure the injured area. Glucose is transported by glucose transporter (Glut) 2 and Glut4, which are transmembrane proteins that act as gatekeepers. We hypothesized that the transport of glucose via G...
