27 – Partial re-treatment of the MB2


#27 Partial re-treatment of MB2 canal

1) H/O RCT 5yrs bk

2) Exploratory endodontic access revealed a blob of GP in the area where the MB2 should be

3) Pre-op revealed a BF which I missed and I introduced another rotary file into the orifice and it separated as well

4) Both files retrieved with U-files

5) Ooze of pus following the removal of file from the channel created which was persistent

6) Internal drain leading to the MB2 placed for 2 weeks

7) Repeated appointments of irrigation and patency through the drain for the two weeks

8) CaOH dressing once the ooze subsided

9) Obturated once symptoms resolved and a dry canal was obtained

10) 3 weeks review revealed significant PA change
