Rare spontaneous formation of a dentin bridge post-dental trauma: A cone beam computed tomography-based case report with root canal therapy
Moslem Rostami, Hengameh Ashraf, Yaser Safi, Bita Heydarzadeh
TL;DR
A rare case of spontaneous dentin bridge formation in a traumatized tooth was diagnosed using advanced imaging and treated with root canal therapy.
Contribution
This case report documents a rare instance of spontaneous dentin bridge formation without therapeutic intervention in a mature tooth following trauma.
Findings
A dentin bridge formed spontaneously beneath an internal resorption area in a traumatized tooth.
Cone-beam computed tomography was critical in diagnosing the dentin bridge and preserving apical pulp vitality.
Root canal therapy limited to the coronal pulp and internal bleaching improved aesthetics and function.
Abstract
Spontaneous dentin bridge formation in mature teeth without pulp exposure or therapeutic intervention is an exceedingly rare phenomenon. This case report describes a 54-year-old male patient presenting with gray discoloration of the right maxillary central incisor (tooth #11) following dental trauma in 2019. Clinical examination indicated coronal pulp necrosis, while periapical radiography and cone-beam computed tomography (CBCT) confirmed internal resorption in the coronal pulp chamber with a thick, regular dentin bridge formed spontaneously beneath the resorbed area. The dentin bridge preserved the vitality of the apical pulp, as evidenced by a normal apical root canal. Treatment involved root canal therapy limited to the necrotic coronal pulp up to the dentin bridge, followed by internal bleaching to improve tooth color and esthetic restoration with composite resin. A 3-month…
