Once in a while, we (OK, just Dr. Wong) goes overboard and wants to document the heck out of a case. So, in pure voyeuristic interest, the following photos depict a step-by-step viewing of a root canal procedure done in our Barrie office! We are sure you’d like the pics, because people like nothing more than looking at surgeries. Without further ado, but with many dentist-specific terms for the truly curious, here is a root canal completed on an upper left first molar (tooth 26, or tooth 14 for the Americans) as seen through the eyes of a dentist. This root canal was done due to obvious dental decay that had reached the nerve of the tooth. In cases like these, there are only two appropriate treatments: extraction of the tooth, or a root canal. Since this was a very saveable tooth, the patient agreed with our suggestion to perform a root canal.
A quick summary of this root canal:
Pre-op diagnosis: vital, pulpal caries
Condition of tooth on access: hyperemic
Final canal instrumentation: MB1: 19mm to 35/0.04 MB2: 19mm to 35/0.04 DB: 19mm to 35/0.04 P: 22mm to #40 SS file
Warmed vertical condensation with GP via SystemB downpack and Obtura backfill.
Global 4-step surgical operating microscope. Here come the Barrie root canal photos!
The actual file sequence was this, for those who really really want to know: Stainless steel files #8 and #10 (Lexicon C-files, Tulsa Dental) to patency, K3 files (Sybron Endo) 15-0.02, then 20-0.02 to length, 20-0.06 to flare coronally, 20-0.04 to length, then 25-0.04, 30-0.04, 35-0.04 to length. The palatal canal was futher instrumented to the apex with a #40 stainless steel file. Canal working lengths were determined with a Root ZX Electronic apex locator (J. Morita). All files were lubricated with RC Prep (Premier Dental).
We hope this provides you with a better understanding of the steps involved in a root canal, or at least the way we do things at the moment in our Barrie dental office. Our routine changes frequently (to the frustration of the dental assistants), but the goal remains the same: disinfection of the root canal system followed by sealing to prevent reinfection, all with minimal compromise to the strength of the tooth.
For a root-canal-related issue, or maybe just a complete examination to assess your overall oral status, please contact us! We’d love to be your Barrie dentist.
