ABSTRACT

Aim

To assess the clinical and radiographic outcomes of 36 transplanted teeth and the possible factors affecting the results.
Materials and methods: In 26 children, 36 teeth transplants were performed. The main reason for transplantations was the loss of
anterior teeth due to trauma; 80.5 of transplanted teeth were immature bicuspids. The transplants were clinically and
radiolographycally monitored in respect of pulp vitality, root canal obliteration, periradicular changes and root formation. Fisher Exact
Test and Kaplan-Meier analyses were performed to determine the association between the variables and estimation of survival rates,
respectively.

Results

Thirty (83.3) of the transplantations were recorded as successful and six as unsuccessful
(16.7). The survival rate was 97.2 during average time of 47.5 months 27.8 SD. Only one tooth had been
extracted and 5 had survived in not ideal conditions. The majority of immature transplanted teeth developed pulp canal obliteration.

Conclusion

Factors associated to successful outcome were immature root formation of donor tooth and short flexible splinting
period. The main factor associated to failure was replacement resorption. The surgical technique did not present statistical significance
in the clinical outcome. Tooth transplantation has shown high success and survival rates, and should be considered as a real option in
growing patients.
