Computer assisted densitometric image analysis (CADIA) of bone density in periradicular bone defects healing.
CADIA can only be performed on geometrically standardized images converted in Al equivalents. The aid of this study was to develop the ability of the new CADIA software to quantify bone density on dental radiographs without previus standardization. A total of 36 examines with periradicular leasion were treated surgically, the defects were filled with Hydroxilapatite and followed up for 1, 6 and 12 months. Before and after surgery the operated areas were clinically evaluated using intraoral radiographs, tooth mobility index and relapses. Clinical results revealed satisfactory bone healing in 27 cases and relapses in 9 cases. The radiographs were then digitized with high resolution CCD camera. Densitometric analysis were done in 10 points at the edge of bone defect. Correction of geometric and brightness distortions was done with mathematical manipulation from three referal points positioned at the same place on each radiograph. Density values observed no bone loss in 23 cases and loss of bone in 13 cases. The differences between clinical evaluation and CADIA were not statistically significant.
