Open apex (by Ilya Mer)

This upper canine #23 was retreated twice, the last time it happened approximately 3 years ago and you see the result. Percussion and palpation were moderate painful. There was significant leakage between composite cement and root canal wall and I had to remove a lot of caries with round bur from dentin canal walls . Apexification with MTA 4 weeks  after calcium hydroxide dressing.  Gelatinous sponges (Gelatamp, Roeko)  were used as a extraroot barrier in order to prevent the MTA getting out of root.
