Summary
Autotransplanted premolars with incomplete roots continued to develop after transplantation. Cone-beam computed tomography (CBCT) confirmed significant root length increase over time.
Area of Science:
- Dentistry
- Oral Surgery
- Radiology
Background:
- Tooth autotransplantation is a viable option for replacing prematurely lost teeth.
- Assessing root development post-transplantation is crucial for treatment success.
Purpose of the Study:
- To evaluate root development in autotransplanted teeth using cone-beam computed tomography (CBCT).
Main Methods:
- Twelve premolars with incomplete root formation were autotransplanted to replace central incisors.
- CBCT scans were taken before transplantation (T1) and after a follow-up of at least 12 months (T2).
- Root length was measured, and longitudinal development was calculated by comparing T1 and T2 measurements.
Main Results:
- A mean root length increase of 2.83 mm was observed between T1 and T2.
- Root development was statistically significant (p=0.001).
- No significant correlation was found between root length increase and the time elapsed between scans.
Conclusions:
- Autotransplanted premolars with incomplete roots demonstrate continued root development post-surgery.
- CBCT is effective in monitoring longitudinal root development after tooth transplantation.
