Trauma: Crown Fracture

November 13, 2026 Michael Trudeau Deep Fix

The 5 categories of crown fractures, uncomplicated and complicated, and how root development and the fragment decide what I do: sealing the dentin, reattaching the fragment with a mounting jig, Cvek pulpotomy, and cases followed to long-term recalls.

Crown Fracture Case: Two Immature Centrals, Cvek Pulpotomies with Biodentine

November 6, 2026 Michael Trudeau Daily Fix

Complicated crown fractures on both upper centrals with open apices, #8 with the piece and #9 without. Cvek partial pulpotomies with Biodentine on both, and no staining at 2.5 years.

The patient is a periodontist and insisted we give it a go. Got the 10 year follow-up the other day. We started with the surgical approach, then added internal calcium hydroxide with resorption removal. He
