Finding the canal in a Md Incisor


This tooth was referred to my office today after the RCT had been started. I appreciate a dentist who is not afraid to stop during a procedure and refer if needed. Here's a tip to help you find these canals.



Look lingually. The natural access into a Md incisor always goes toward the buccal. If you cannot find the canal (or the second canal in 20-40% of these teeth), look lingually.



I used an ultrasonic tip under the microscope to cut from the current access back towards the lingual.





That's it. Remember to look lingually.

Thanks for your correction. Benjamin & Dowson foun 2 canals in 41.4% of Md incisors. 1.3% had separate foramina.

Green's earlier study found 2 canals in 20%.

Either way, I was off. Thanks for your correction!
