NCT06943846

Brief Summary

The purpose of this study is to better understand oral wound healing in the aged participant following placement of platelet-rich fibrinogen (PRF). In this study, 12 participants requiring a posterior tooth extraction will be enroll: 6 participants aged 14-18, 6 participants aged 50-80. All will undergo a posterior tooth extraction with a small tissue specimen taken from the extraction site. Half of the participants will also have their blood drawn and platelet-rich fibrinogen placed in the extraction socket. Participants will return in 2 weeks for suture removal and another soft tissue sample. Participants will return at 3 months for a final post-operative radiograph. All soft tissue samples will undergo immunofluorescence.
