Ellis class III fractures expose the pulp; in a 9-year-old with an immature permanent incisor, the treatment of choice is a vital pulp therapy that preserves pulp vitality and allows continued root development—namely a partial (Cvek) pulpotomy after radiographic assessment. Studies show high success rates for Cvek pulpotomy in complicated crown fractures treated within the first few days after injury [Bimstein & Rotstein 2016, PMID 27397639; Blanco & Cohen 2002, PMID 12519051].
