Study summary

Dental traumatology is a field of dentistry , especially in pediatric age, but also in adulthood with permanent dentition. Dental trauma has a higher incidence in preschool, school-age, and adolescent patients, accounting for about 5% of injuries for which the intervention of a specialist physician is required. Traumatic avulsion of permanent teeth accounts up to 0.5-16% of all dental injuries and is considered one of the true emergencies in dentistry.The treatment of choice in case of traumatic avulsion of permanent teeth is the quickest-as-possible replantation. The primary objectives of this prospective study were to evaluate the incidence of complications and survival rates of replanted teeth over time. The secondary objectives were to assess and to examine the correlation between the development of complications and factors such as extra-oral time, storage media, root maturity and the presence of alveolar fractures.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2020 to primary completion in Nov 2025, 60 months.

Of 265 non-industry observational studies under Wounds and Injuries, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 60. This study's 60 months is above that.

Counting every sponsor, half of 312 studies reached it within 28 months; a quarter within 12 and three quarters within 60.

Wounds and Injuries covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 12, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
