简要总结
This prospective clinical study evaluates bone healing following dentigerous cyst enucleation associated with impacted mandibular third molar extraction. The study compares spontaneous blood clot healing, Advanced Platelet-Rich fibrin (A-PRF), and A-PRF combined with Autogenous Dentin Demineralized Matrix (ADDM). Bone healing is assessed as the primary outcome, while postoperative pain intensity assessed using the Numerical Rating Scale (NRS) with graphical representation represents a secondary outcome. The study aims to determine whether the use of A-PRF or A-PRF combined with ADDM improves postoperative healing outcomes compared with spontaneous blood clot healing.
详细描述
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. Autogenous Dentin Demineralized 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.
