Abstract
The aim of this case series was to describe the endodontic management of 3 immature
permanent teeth that sustained traumatic injuries and subsequently presented with
complete ingrowth of mineralized tissue into the canal space. Ingrowth of bone/mineralized
tissue into the canal has been considered a poor long-term outcome with an inherent
risk of ankylosis. In cases 1 and 2, no endodontic treatment was undertaken, except
for emergency management requiring splinting. The cases were followed for 36 and 23 months,
respectively. No ankylosis was evident over the review period, and normal teeth eruption
was apparent. In case 1, the tooth was treated orthodontically and was responsive
to pulp sensibility testing. In both cases, there was an appearance of an internal
periodontal ligament–like space on the inner root wall of the canal. In case 3, 2 years
postinjury, pulp necrosis and apical periodontitis occurred, and the tooth was managed
with regenerative endodontic treatment consistent with the European Society of Endodontology
and the American Association of Endodontists guidelines/recommendations for a regenerative
procedure. The case was followed for 8 years after regenerative endodontic treatment.
No ankylosis was noted with normal eruption of the teeth. The tooth was responsive
to pulp sensibility testing despite the ingrowth of mineralized tissue, which was
confirmed clinically.
