A Comparative Study of the Biocompatibility of Two Root-End Filling Materials in Rat Connective Tissue
SUMMARY: The aim of the present study was to examine the short-term biocompatibility of Endosequence Root Repair Material (ERRM) paste and white Mineral Trioxide Aggregate MTA by implanting them into polyethylene tubes in the subcutaneous connective tissue of rats. twenty five male Wistar rats, 3-4...
