Abstract
Introduction
After a traumatic injury to the upper central incisors of a 7-year-old patient, avulsion
of tooth #9 and pulp exposure after crown fracture of tooth #8 were managed.
Methods
After immediate replacement of tooth #9 in its socket, teeth were splinted for 3 weeks.
No endodontic treatment was performed on tooth #9, but pulp capping was performed
with mineral trioxide aggregate (Pro Root MTA; Dentsply Maillefer, Ballaigues, Switzerland)
on #8, and both teeth were restored with composite resin. The teeth were monitored
every 3 months for 2 years.
Results
At 24 months, both teeth responded positively to electrometric tests and roots showed
normal development, but an abnormal reduction in the size of the root canal space
of tooth#8 was observed.
Conclusion
Based on these observations, we discuss odontoblast behavior in the context of the
stage of dentinogenesis and the probable disturbance of regulation of the physiologic
dentinogenic secretory processes in the pathologic situation.
