Although zinc oxide and mineral trioxide aggregate (MTA) pulpotomies for primary molars have been documented in the literature, virtually all such pulpotomy/stainless steel crown procedures are performed to treat invasive caries lesions that have infected primary molars from their occlusal or occlusoaxial aspects. There is a dearth of evidence regarding primary molars requiring pulpotomy and restoration with a preformed stainless steel crown due to traumatic injury.
This case report documents the step-by-step repair of a fractured maxillary right primary first molar in a 6-year-old girl. She had been playing "cops and robbers" in her home when she fell on her face, striking and cutting her chin. After the chin laceration was sutured at a local hospital emergency room, the patient was brought to the dental office to have her teeth evaluated for injuries. The blow to her chin had crunched the posterior mandibular teeth against the opposing maxillary posterior teeth. As a result, the buccal aspect of her maxillary right primary first molar was sheared subgingivally, but still in place, and the pulp chamber was exposed. The mesiobuccal cusp of the adjacent primary second molar was also struck, and it demonstrated evidence of an internal craze fracture. Following pulpotomy and restoration of the fractured tooth with a stainless steel crown, the patient was followed for 3 years and 11 months, with no further treatment needed, until the tooth was extracted at the request of her orthodontist. The second molar with the craze-fractured cusp was closely monitored but required no treatment until it exfoliated.
