RCT 38: SIP & SAP
I decided to take this case only because the patient is a colleague and she has a good mouth opening to access the tooth.
The 38 was in good occlusion with the opposing 27 and removing the 38 would lead to overeruption and a cascade of future problems.
Few points to note: proximity of the IAC, calcifications in the chamber.
There was a lot of bleeding upon access which took some time to arrest after copious irrigation.
Managed to clean all 3 canals at first visit, however symptoms resolved fully only after 2nd visit of intracanal medicament.
Obturation with bioceramic sealer and 0.5mm short of distal apex as I don't want to risk ANY sealer extrusion into the IAC.
Final core buildup with bulkfill composite.

Colleague referred a previously RCT premolar with unresolved abscess and pain. The RCT was done with a good protocol and well obturated.
Going into this case there are 2 options:
1. Retreatment 2. Apical surgery.
We decided to start with retreatment with the possibility that an apical surgery will still be necessary.
After accessing through the crown, patient felt pain during GP removal in mid-buccal canal.
With a closer look under microscope a vertical crackline is visible on the buccal root wall.
Sadly, this makes the tooth unrestorable & needs an extraction and replacement.

Sometimes patient factors will make a RCT case much harder than the tooth itself. Thank you for taking over the crown part.

Retreatment in an upper lateral incisor. Very long and curved root prevent abscess from perforating the bone which led to a lot of pus buildup and pain. It took more than usual visits to remove all discharge.

One of the most challenging cases in recent weeks.
Young girl self referred to complete RCT on her lower left first molar. The case was started elsewhere and the dentist wasn't able to find another 2 canals.
Pre-op IOPA shows
- partially cleaned canals
- canals are not visible at apical thirds
- possible ledges given the direction of root curvature vs filing direction
- bulbous roots, always a sign of difficulty in my experience
- extraradicular infection
When I entered the canals, all 4 canals were ledged, all were curved apically, all were sclerotic. 🤯
It took 4 hours and many C+ files just to negotiate the canals. Finger cramps were very real. Glad that it ended well because I was on the verge of giving up.

Old gentleman complained of pain on biting hard foods and spontaneous nocturnal pain. Diagnosed with SIP and SAP. Exam revealed 37 with a crack through the distal marginal ridge extending into pulp space. Important considerations for this case:
- lone standing second molar in Q3
- adjacent to an acrylic denture
- very heavy occlusion which contributed to the crack
- distal root resoprtion from deep impacted wisdom tooth
- deep pulp roof
A thorough exam + CBCT allows accurate root canal instrumentation of the distal apex.
Using pre-op Digital design printed crown reduces issue of high contact point, which is very common in second molar crowns and avoids current denture fit.
