Detaillierte Beschreibung
Dentigerous cysts are among the most common odontogenic cysts and are frequently associated with impacted mandibular third molars. Surgical enucleation combined with impacted tooth extraction may result in postoperative bone defects and complications related to tissue healing. Various regenerative approaches have been proposed to improve postoperative healing and bone regeneration following cyst removal.
Advanced platelet-rich fibrin (A-PRF) is an autologous platelet concentrate rich in growth factors that may enhance soft and hard tissue healing. Allogenic dentin-derived matrix (ADDM) has been introduced as a biomaterial supporting bone regeneration and defect filling. However, limited evidence exists regarding their effectiveness following dentigerous cyst enucleation.
This prospective clinical study compares three postoperative management protocols following dentigerous cyst enucleation associated with impacted mandibular third molar extraction: spontaneous blood clot healing, A-PRF application, and A-PRF combined with ADDM.
The primary outcome measure is postoperative bone healing assessed during radiological follow-up. Secondary outcome measures include postoperative pain intensity evaluated using the Numerical Rating Scale (NRS) with graphical representation on the day of surgery and on the second and sixth postoperative day.
The study aims to determine whether regenerative treatment with A-PRF or A-PRF combined with ADDM improves postoperative healing outcomes compared with spontaneous blood clot healing.
