Endodontics

The mesial roots of maxillary molars and lower molars are the most challenging and variable of root canal shapes and types. This single root may have a multitude of root canals and I have seen anywhere from 1 to 4 canals in this single root. As endodontists we have the education, skills and equipment to…

Unique parts are that there are 3 canals of the mesial root that join to one common apex (root end).

Three canalled lower molar with lateral canals and inter connections between the mesial root systems. This is achieved using high volume of irrigation and warm vertical compaction of our root canal filling material (gutta percha).

MB and ML join at the apex with inter connections of the two root systems (anastamosis).

There were 4 separated canals with 4 independent roots. This tooth was diagnosed as asymptomatic irreversible pulpits with a secondary condensing osteitis. The white opaque bone at the apexes of the roots will return to normal looking bone in a few years.

Interesting features was a third molar with 3 canals joining to a single canal at the end of the roots (apex).

Seven canals were located, cleaned, shaped, disinfected, sealed and had an amalgam core build-up. This tooth was featured and published in a dental journal.

Four canalled lower second molar with four in-depended root canals. A 12 month re-evaluation shows good bone healing.

Four canalled lower first molar. Most distal roots of lower molars should be treated as if they always have two canals in them. The root canal was completed and restored with blue build-up composite by request of his general dentist prior to a new crown being made.

Most notable about this case was that the canals were severely curved and almost a 90 degree on the back (distal canal) with lots of sealer puffs on all the roots.
