Posted on By R. Terry Councill In Digital Scanning & CAD/CAM

Pt is a mid 50 year old healthy female. Presents with GREAT FEAR and desires rehabilitation. CBCT to assist in determining Tx. plan. In review, noted bifurcated IANB on L side. It appears to play out as seen on the cross section and in my drawing, but unsure. Literature reports bifid canals are reported to be present less that 1.0% of the time. How would you handle?? Comments??

Terry; I have seen this before further forward in the 1st molar area as well as an earlier exit for the mental foramen. IT is often an accessory nerve branch but best to plan to stay away from it in your planning. regards Dr. S
