Conclusions
This study showed that it is possible to preserve a living dentin-pulp complex after tooth extraction during 7 days.
Methods
Twenty intact third molars, after preparation, were divided into four groups, with five samples each. We placed the negative control samples (C) in saline, and the tested groups were placed (T) in supplemented DMEM, at two different times: 1 and 7 days. The specimens were processed for light microscopy observation.
Results
Contrary to C-groups, T-groups showed a functional dentin-pulp complex. The treated dentin-pulp complex presents normal histological appearance. Conclusions: This study showed that it is possible to preserve a living dentin-pulp complex after tooth extraction during 7 days.
