ABSTRACT:
A dental root canal sealing composition curable in the absence of a polymerisation initiator, which comprises (i) an amino terminated prepolymer having a viscosity at 23° C. of less than 100 Pas. (ii) a compound capable of undergoing polyaddition with the aminoterminated prepolymer (i); (iii) 40 to 85 wt.-% of a filler for providing a minimum radioopacity of at least 3 mm/mm Al.
