PURPOSE: This study radiographically evaluated the changes that occur in jaw defects after enucleation of cysts and either grafting with demineralized freeze-dried bone allograft (DFDBA) or packing with absorbable gelatine sponge (Gelfoam).
PATIENTS AND METHODS: Thirty-two patients (14 males, 18 females) with cystic lesions of the jaws were divided into two groups. Group A underwent enucleation and bone grafting with DFDBA. Group B underwent enucleation and packing with Gelfoam. Both groups were evaluated radiographically before surgery, immediately postoperatively, and 6, 12, 24, and 36 months postoperatively. The density of the area was measured with a digital densitometer.
RESULTS: The density in group A was significantly (P < .05 to .01) greater than in group B at 6 and 12 months postoperatively. The difference at 24 months was not significant. Group A reached density levels at 6 months that were reached by group B at 12 months.
CONCLUSION: The findings demonstrate that decalcified freeze-dried bone allograft enhances bone healing in jaw defects after cyst removal.
