In a mandibular first premolar, a sudden canal disappearance, eccentric file position or unexplained radiographic line should prompt a search for a split system. The challenge is finding anatomy without weakening the root.

I start with angled periapicals and magnification, then justify limited-field CBCT only if it will change treatment.

A reproducible glide path and controlled irrigation matter more than forcing an instrument into a suspected branch.
If a file separates during negotiation, use the risk-based broken-instrument pathway: dentalreach.today/removal-of-a-broken-instrument-an-endodontic-challenge
Complex anatomy plus limited visibility is a sensible referral threshold.
