Abstract
Quality of CBCT images allows for detailed analysis of bone but tissue mineral density can be evaluated with some limitations. The purpose of this study was to investigate the clinical possibility to measure the mandible relative radiological bone density for cortical and trabecular tissue. The CBCT scans were taken with the use of PaxReve3D machine and analyzed by Ez3DPlus software. A modified scale was applied and the ratio of radiological density to measured highest value (HV) was calculated. The relative grey values (GV) of alveolar bone in mandible were measured. Basal cortical reference values (BCRV) of bone density were applied and compared with HVs. Statistically significant very strong positive correlation was observed between relative and rescaled GV for all available data r = 0.901; p 2 = 0.409. With the limitations of the study the use of relative grey scale values to evaluate radiological density of mandible is promising and easy to apply method.
