-Abstract-
Trauma to the tooth is the most common accidents in pediatric dentistry and tooth
fracture occurs frequently.
Fracture is classified into crown fracture, root fracture, and crown-root fracture which
involves both. Also, it is classified into simple or complicated fracture depending on
whether the pulp is exposed or not.
When the fracture is extended down to the subgingival level following the long axis
of the root, or when more than 1/3 of the root is involved, extraction is the primary
treatment. But alternative treatment such as extruding the root fragment with
orthodontic force and restoring it, or intentionally extracting the tooth and replanting it
to a position which it can be restored.
This is a case report on intentional replantation of a traumatized maxillary central
incisor with crown-root fracture of a patient with mixed dentition. The teeth was
extracted and immediate endodontic treatment, retrograde filling and resin restoration
were carried out.
