Adenomatoid odontogenic tumor is frequently not diagnosed preoperatively even when radiographs are available. This study evaluates radiographic findings with special emphasis on the characteristic radiopacities of adenomatoid odontogenic tumor. In correlating radiologic findings with pathologic findings, differences in diagnostic accuracy between intraoral periapical and panoramic radiographs were found. The intraoral periapical radiograph allows perception of the radiopacities in adenomatoid odontogenic tumor as discrete foci having a flocculent pattern within radiolucency even with minimal calcified deposits. Panoramic radiography was often unable to demonstrate radiopacities in adenomatoid odontogenic tumor when the calcification was minimal. The result indicates that intraoral radiographs may be essential for correct radiographic interpretation of an adenomatoid odontogenic tumor in the presence of minimal quantities of calcified deposits.
即使有X线片，腺牙源性肿瘤在术前也常常无法被诊断出来。本研究评估了X线表现，特别强调了腺牙源性肿瘤的特征性不透光区。在将放射学表现与病理学表现相关联时，发现口腔根尖片和全景片在诊断准确性上存在差异。即使钙化沉积极少，口腔根尖片也能将腺牙源性肿瘤中的不透光区视为在透射区中具有絮状形态的离散病灶。当钙化极少时，全景片常常无法显示腺牙源性肿瘤中的不透光区。结果表明，在钙化沉积量极少的情况下，口腔内X线片对于正确解读腺牙源性肿瘤的X线表现可能至关重要。
