    Abstract: Disclosed is a root filling paste for dental surgery, containing calcium hydroxide, an X-ray contrast agent and oleum pedum tauri as the paste matrix or base, respectively. The addition of oleum pedum tauri permits the calcium hydroxide which could heretofore be filled into root canals with difficulty only, to be filled evenly and in sealingly filling manner into the root canals of gangrenous teeth. The anti-inflammatory and osteo-regenerating activity of calcium hydroxide may in this way come into effect regularly.
