Abstract
Introduction: We had hypothesized that the gelfoam has effect in Promoting Bone Regeneration 
After Maxillofacial Cyst Enucleation. Methods: Eighteen patients with maxillary cysts had been 
treated, they were selected and randomized into 2 equal groups: 1- Control group (A) (lesion were be 
enucleated and not be subjected to any graft material). 2- Experimental group1(B) (subjected to only 
gelfoam placement in bone defect). CBCT scan was performed for each patient to evaluate bone 
density immediately and after 6 months. Results: All groups showed decrease in bone defect size 
after 6 months .and with no markable difference. Conclusion: Gelfoam could be a candidate for a
bone-scaffold in low-load areas or as a drug delivery carrier to promote bone regeneration in defective 
areas.no as aprimary materials for regeneration.
