17 Dec Dens Invaginatus in the dog…a periodontal and endodontic disease process
This is a very interesting case. Note the gingivitis between the two roots (circled area). Probing must be performed next to assess for any pockets, followed by dental radiography.
Dental radiographs confirm a tooth that has roots that converge along with a pulp stone in the pulp canal. Finally, there is a LEO (lesion of endodontic origin) that indicates the tooth is dead.
This is called dens invaginatus. It has a tooth defect where the two roots converge. This allows bacteria to enter the pulp cavity which started the whole inflammatory/infectious process, killing the tooth. This tooth must be surgically removed. It also can occur on same tooth on the opposite jaw.
Always take dental x-rays to get the whole picture underneath the gum line!
