1. Unfilled buccal canal in tooth 15
Tooth 15 contains an unfilled buccal canal, which is the source of the periapical rarefying osteitis. This canal is positioned approximately 2 mm buccally to the existing filled canal, and can be accessed at the level of the floor of the pulp chamber. Approximately 1.5 mm of dentin excavation may be required to uncover the buccal canal.
