PURPOSE: This study compared spontaneous bone healing and regeneration obtained with deproteinised bovine graft in residual cavities after mandibular cyst enucleation using computed tomography (CT) Dentascan. MATERIALS AND METHODS: Eighty patients with a radiological diagnosis of mandibular cyst underwent surgical enucleation. Patients were divided into a control group (spontaneous healing, 40 patients) and a test group (deproteinised bovine graft, 40 patients). All patients underwent follow-up CT Dentascan 12 months after the procedure. For each residual cavity, apical-coronal and mesial-distal distance, average pixel intensity and volume were calculated and results compared between two groups using the t test. RESULTS: The control group showed mean volume, apical-coronal and mesial-distal distance of 703.2±185.3 mm(3), 28.6±9.4 mm and 25±2.84 mm, respectively. In the test group, values were 738.2±189.2 mm(3), 27.5±3.6 mm and 25.3±2.97 mm, respectively. There was no statistically significant difference between groups. Average pixel intensity was 1,102.8±124.3 in the test group and 624.9±133.3 in the control group, with a significant difference between groups (p<0.0001). CONCLUSIONS: The significantly higher average pixel intensity observed in the test group demonstrates the cavalue of treatment with biomaterials to obtain earlier bone regeneration.
