Abstract

The science on the existence of maxillary and mandibular cortical bone thickness and density of prehistoric human which had been found from Pawon cave, are still uniden- tified by any research, further more if it is compared with those of modern human. The aim of this study was to investigate the Pawon-man’s maxillary and mandibular cortical bone thickness and density by using a 3D Cone Beam Computed Tomography imag- ing. The research method is a descriptive one which was consisted of 3 maxillas and 3 mandibles of Pawon-man as samples. This research was conducted by using Ez Implant software used in 3 dimensional aspects (axial, coronal and sagittal). All aspects were re- corded, collected and presented in tabular form. The Pawon-man’s maxilla showed that the average of cortical corpus bone thickness was 1,53 mm with the average of density of 971,98 HU, meanwhile the average of cortical alveolar crest bone thickness was 0,69 mm with the average of density of 750,87 HU. Whereas the Pawon-man’s mandible aver- age cortical corpus bone thickness was 3,43 mm with the average of density of 1042,26 HU, on the other hand the average cortical alveolar crest bone thickness was 0,89 mm with the average of density of 995,45 HU. The result of the interdental region measure- ment showed the highest cortical bone thickness of maxilla was located in the F region (interdental region Molar 1 and Molar 2) with the average thickness of 1,29 mm and the average density of 887,80 HU, whereas in mandible which was located in the E region (interdental region Premolar 2 and Molar 1) with the average thickness of 2,61 mm and the average density of 999,22 HU. The Pawon-man’s mandible has more cortical bone thickness and density compared with those of Pawon-man’s maxilla with highest cortical bone thickness which was located in the posterior region and the cortical bone thickness of Pawon-man’s jaw was higher than modern human’s.
