Compositions comprising radiopaque substances with improved bioabsorbability

Abstract

Provided is a biostable radiopaque substance that is absorbed within living tissue or inflammatory lesion in living tissue and uses thereof. The radiopaque substance does not cause an inflammatory reaction in surrounding tissue and is rapidly absorbed before healing occurs, thereby not interfering with healing and regeneration of damaged tissue. Therefore, the radiopaque substance of the present disclosure can be included in a biotransplantation material, for example, a root canal filling material for endodontic treatment, and be effectively used.

Dependencies are inferred from the claim text.
