The size of pulp cavity may be a key to find one’s age out of unidentified person. Dental CBCT was expected to be a suitable modality to evaluate the size of pulp cavity due to high image resolution. However is was not studied that which three dimensional imaging technique should be used to observe pulp cavity. The aim of this study is to determine a standard three dimensional imaging parameters to evaluate the size to pulp cavity. Using micro-focus CT system, volumetric CT image data of fifteen extracted human mandible incisor or canine was acquired. The size of a voxel was 0.04mm. Cross-sectional three dimensional (3D) images of extracted teeth were rendered using ray-sum (Average) image, minimum intensity projection (MinIP), maximum intensity projection (MIP) and volume rendering (VR) technique. The cross sectional planes to observe axial, labio-lingual and distal-medial view of pulp cavity were set. The thickness of stacking image layer changed from 0.4 to 2.0mm. The pulp cavity ratio that is an occupancy ratio of pulp cavity in the cross sectional area of a tooth was studied. In the mandible incisor and canine, the labio-lingual cross sectional images revealed higher pulp cavity ratio than axial and distal-medial plane. Among 3D images techniques, the average and MinIP rendering technique provided better depiction of pulp cavity the MIP and VR images. In the average and MinIP image, the pulp cavity ratio was increased in thicker stacking image layer.","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8676","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KITA,
