Abstract


Objectives: According to the studies, the best time for endodontic treatment after accidental replan-tation is no more than two weeks. Unlike cases of tooth trauma, in autotransplantation, all the manipulations flow under relatively sterile conditions and the likelihood of pulp infection is minimal. We decided to check out the resorption rate in case of different terms of pulp extirpation and whether revascularization is possible with a favorable healing course. Material and Methods: In this study we performed the autologous transplantation of closed-apex third molars in 52 adult patients, divided in 3 groups. In the 1st group (8 cases) the pulp extirpation was done before the surgery, in the 2nd group it was performed in 2 weeks after the surgery (33 cases). In the 3rd group there was no treatment at all (11 cases). Results: Results were evaluated after 3, 6, 12, 24 months by clinical and radio-graphic examination. The survival rate and the pulp condition of the transplanted teeth was observed. The dynamic periotestometry examination was performed in order to track the resorptive processes. For statistical data processing we used the Mann-Whitney test. Conclusions. No dependence of the development of inflammatory and replacement resorption on the time of pulp extirpation was evaluated. During this observation period direct confirmation of revascularization has not been obtained. Despite possible pulp necrosis inside the transplanted tooth, the risk of inflammatory resorption is minimal in the absence of infection. Periotestometry data showed that process of replacement resorption stopped after 6 months in most cases.
