| Outline of Final Research Achievements |
Mandibular horizontal impaction tooth is one of the most common surgical procedures encountered in oral surgery clinic. In this study, we examined whether or not it is possible to promote healing of tooth extraction cavity by extracting dental pulp tissue from extracted teeth immediately after tooth extraction and transplanting to tooth extraction cavity just after tooth extraction of mandibular horizontal impacted tooth. Both sides of upper first molar of the mouse were extracted. The pulp tissue was removed from this extracted tooth and after implantation in the extraction tooth cavity, the healing process was observed histologically time dependent. As a result, on the dental pulp tissue transplant side, there was a tendency to promote healing, but there was no obvious significant difference. In the future, we plan to investigate using scaffold-based substrates when transplanting dental pulp tissue.
