Keywords:В Cone-beam computed tomography, Hounsfield units, grayscale values This factor determined is highly reproducible and reliable in radio-opaque regions, and adequately reliable in anterior and posterior interdental regions. Conclusion: In well-exposed regions, a defined conversion factor can be established between grayscale values and HUs in Galileos Software. In radio-opaque regions, grayscale values were 1.4 times greater than HUs and highly reliable (r = 0.972). The reliability of values obtained was verified using Kappa's correlation test. In posterior interdental regions, gray scale values were 4.5 times greater than HUs. Results: In anterior interdental regions, grayscale values were 7.6 times greater than HUs. The reproducibility of the factor obtained was also assessed to improve its clinical correlation. Grayscale value was divided with HU to obtain conversion factors at different sites, which was the primary outcome of the study. Reference landmarks were isolated 1) between anterior interdental regions 2) between posterior interdental regions, and 3) at radio-opaque regions. Grids were used for standardizing reference planes at different anatomical sites. Sites assessed were isolated in both softwares at identical locations. Methods: Eighty-seven (87) CBCTs were included in this retrospective study and 343 sites were assessed across different anatomical regions. Aim: To determine a conversion factor and test its reliability and reproducibility for grayscales values to HUs obtained in Cone-beam computed tomography (CBCT) s at various anatomical regions using Galileos Sirona CBCT Viewer Software and Philips DICOM Viewer. Establishing a linear relationship between grayscale values and Hounsfield units (HUs) in softwares can improve the ease of diagnosis and treatment planning. Background: Bone density assessment in dental practice is required for dental implant planning and placement, Orthodontic tooth movement, and establishing mid palatal suture maturation.
