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.
#30 Pulpitis. Caries involving the ML cusp. Caries driven access planned Mb located in the middle of the floor and the dentinal map suggested a ML orifice present almost on the lingual wall of the tooth unlike the usual. I had to stick to what I could see rather than go to the usual co-ordinates to […]
Pre-op Assessment: Severe attrition and a constricted pulp chamber. Treatment plan: Access cavity planned taking into account the regression of the pulp chamber size. Canals shaped through the angles the canals project centrally.
Just for Capt Kirk!
Patient in pain to hot/cold after the amalgams were taken out and replaced with composite. Routine MIE access, four canals. Patient doing well.
