Abstract : The objective of this study was to evaluate the quantitative bone density of the maxilla using Cone Beam Computed Tomography (CBCT) of Kurdish population in Sulaimani city and Comparing between bone density in the anterior, premolar, and molar areas also in relation to sex and age. A total of 140 CBCT of Kurdish population of both sexes with age range (20-80 years). At each implant site, the bone density has been assessed twice. A mean value has been taken to assign for that region in edentulous patients or partially dentate patients. One investigator has taken all the readings to eliminate any potential for bias, and the study is containing CBCT from one system. The maximum value was (1466.6 HU) and the minimum value was (23.3 HU) and the median was (532.1 HU). The result shows that there is no statistical difference between males and females (p-value 0.981), While the Kruskal-Wallis H test shows a significant difference between the regions (anterior, premolar, and molar) regions (p-value = 0.000). The anterior region shows the highest ranking followed by the premolar region and lastly the molar region. The most common bone type of upper jaw in Kurdish population was D3 and the less type was D1. The anterior region shows the highest ranking (347 HU) followed by the premolar region (275HU) and lastly the molar region (195 HU). Compared with other populations this study demonstrated that the bone density of Kurdish population was lower than others. This aids in racial determining in forensic dentistry and implant prognosis.
