A Short Case Study: A Two-Headed Snake Anatomy on Tooth No. 15

Rico D. Short, DMD


A patient came in with pain on tooth No. 15. The diagnosis was a necrotic pulp with acute apical periodontitis. The pre-op radiograph looked a little bit eerie (Figure 1). I performed endodontic treatment in one visit.

The cavosurface floor was very deep in the tooth, approximately 10 mm. Also, the roots were very long and curvy, which made instrumentation very challenging (Figure 2). But I was pleased with the result. The mesiobuccal root split in the apical one-third like a two-headed snake (Figure 3). It was very eerie, but beautiful! #WorthSaving
