Abstract :
The aim of this paper is to present the clinical and radiological outcome of the treatment involving a delayed tooth replantation after
an avulsed immature permanent incisor, with a follow-up of 1 year and 6 months. An 8-year-old boy was referred after dental trauma
that occurred on the previous day. The permanent maxillary right central incisor (tooth 11) had been avulsed. The tooth was handheld during endodontic therapy and an intracanal medication application with calcium hydroxide-based paste was performed. An
apical plug with mineral trioxide aggregate (MTA) was introduced into the apical portion of the canal. When the avulsed tooth was
replanted with digital pressure, a blood clot had formed within the socket, which moved the MTA apical plug about 2 mm inside of
the root canal. These procedures developed apical revascularization, which promoted a successful endodontic outcome, evidenced
by apical closure, slight increase in root length, and absence of signs of external root resorption, during a follow-up of 1 year and 6
months.
