When Accessing through metal or Metal-ceramic crowns, the apex locator gives wrong readings if the file is in contact with the metal part of the crown. One way to prevent this is to block the metal margins of the access cavity with Opaldam.
The previous practitioner fractured an instrument in the mesio-buccal root and referred this case. Instrument retrieval is usually fast and quite predictable in locations like the middle and coronal thirds.
This patient had sensitivity to cold after an RCT on a lower molar. Sensitivity persisted even after a month. Re-treatment revealed a missed distal canal/root that was still vital and hyperaemic. Here is a short lecture of the same case:
This case was referred by another practitioner who attempted to locate the canal, but couldn’t find it. The practitioner had perforated palatally in an effort to search for the canal. The perforation was supra-crestal and was sealed with Glass Ionomer. When viewed under the microscope, one can clearly see the calcified portion of what used […]
This Mandibular second molar started off as 3 canals merging into 2 and finally exiting as a single portal of exit.
This patient was from The U.S. I re-treated a lateral incisor tooth of his while he was in Bangalore. He then went back to U.S. I received a mail from him two years later saying that the tooth we did was hurting. I thought that maybe, the lesion had recurred. I referred him to an […]
This patient presented with a large lesion associated with a previously endo treated central Incisor with a open apex. The adjacent lateral tested non-vital. I did Endo on the lateral incisor. In the central, I decided to pack Calcium hydroxide till the lesion shrank in size before obturating with MTA. The plan was to keep […]
This was a case which was started by another clinican. A Naso-palatine cyst was mis-diagnosed as lesion of endodontic origin. The clinician opened up two central incisors, broke an instrument in one, couldn’t locate the canal (nearly perforated) and then referred the case.
This patient had a lesion involving three teeth in the mandibular anterior region. He was seen by multiple clinicians and all of them had advised endo on 3 teeth followed by surgery. I treated just the one tooth which tested non-vital. I placed Long-term calcium hydroxide (6 months) to see some evidence of healing before […]
This is a “garden variety” endo. The best time to refer a case to an endodontist with a microscope is before the pulp has been touched. That way, the endodontist can control how much of tooth structure is removed to complete the endo. In this case, I had to chase all the cracks before restoring
