Purpose: Tooth transplantation is a treatment that uses non-functional teeth to compensate for defects caused by tooth extractions. Surgical procedures have yielded high success rates in autologous tooth transplantation using a tooth with a complete root. This study aimed to evaluate periodontal tissue healing after transplantation of 14 molar teeth.
Materials and Methods: Fourteen individuals aged 28–53 years who underwent autologous transplantation of third molars with completely developed roots between December 2010 and March 2017 were included in the study. The donor tooth was carefully extracted, placed into the prepared transplant site, and stabilised with an orthodontic wire and 4-0 silk sutures for a few weeks. Endodontic treatment was performed after 3–4 weeks. To evaluate the periodontal tissue healing, clinical measurements of the probing pocket depth (PPD), clinical attachment level (CAL), and keratinised gingival width (KGW) were performed, along with radiographic examinations of bone defect fill (BDF) at baseline and at 6 and 12 months after surgery. Statistical analysis was performed using the Mann–Whitney U test.
Results: The changes in PPD and CAL at baseline, 6, and 12 months were statistically significant (P <0.05). KGW did not show a statistically significant decrease. The postoperative-BDF amount at 6 and 12 months was 2.2 ± 1.4 and 4.2 ± 1.4 mm, respectively.
Conclusion: Periodontal tissue healing may occur in tooth autotransplantation even in the presence of complete root development in the donor tooth.
