Description
Summary:This report describes the unexpected formation of root-like structures following the avulsion of immature permanent teeth without replantation. A 6-year-old female patient had avulsed the four permanent mandibular incisors and the two deciduous mandibular canines. The patient was seen in an emergency healthcare unit but did not receive specialized treatment for tooth replantation. As follow-up treatment, she received a removable prosthesis. After 4 years of follow-up, an image obtained by panoramic radiography showed formations similar to four root structures in the alveolus of the previously avulsed permanent teeth. This finding was confirmed by periapical radiography and computed tomography. This case report demonstrates that in teeth with incomplete root development, even after avulsion without replantation, cells from the pulp stump may have the capacity to form mineralized structures that appear radiographically comparable to root dentin.
