#16 – Root canal retreatment This one had a firm and corroded silver point (1) which had a full length engagement and a H-file (2) Missed MB2 canal and a badly gouged floor (3) Treatment done (1) Silver point carefully removed by creating space around it and a custom loop (2) U-file to remove the […]
#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 […]
36 Re-endo Someone has attempted something like a truss a decade back i guess. Restorability assessment Pulp chamber cleaned up Pre-endo Build-up GP removed in all 5 canals and shaped followed by CaOH Distal canal with internal resorption Obturation – WVC
#46 with caries involving the DL cusp. The amount of tooth structure that would be lost if a conventional SLA access is opted for unimaginable. But i did have SLA in this case as well but from the back 😉
This one had Significantly large irregular canals. Palatal canal obturated with a squirt to get a 3-D fill and the buccal canal with a large POE obturated with MTA at the apical 3rd and back-filled with GP. Done in 2-visits.
27 – routine exploratory access to assess prognosis prior to re-endo Clinical Picture suggestive of over-zealous preparation and yet a lot of necrotic tissue inter-twined with the GP
Pre-op Clinical # in the distal wall Perforation Palatal canal located Buccal canal located Perforation site prepared Slim preparation to prevent further dentin loss
#19 with (1)# file in the MB (2) Ledged ML (3) Screw post in the distal. The file dislodged with a U-file and ultrasonics to sand away the composite and vibrate out the post. Fibre-post in the MB and distal canals. Getting that 1.5-2.5 mm ferrule in the lingual side will be crucial in this case.
Somehow i find these premolars canals that splits in the middle 3rd harder to locate and shape than the ones that split in apical. Heat treated NiTi’s come in really handy in these cases.
