Outline of Final Research Achievements

This study carried out eye lens dose measurements using a head phantom by radiological inspection. We affixed fluorescence glass dosimeters to a head phantom and measured the absorbed doses during intraoral radiography, panoramic radiography, cephalography, helical scan computed tomography (helical CT), and dental cone beam computed tomography (dental CBCT).Although helical CT recorded high measured value, it was still lower than the recent ICRP recommended threshold.

Academic Significance and Societal Importance of the Research Achievements

歯科治療におけるエックス線検査は口腔内X線撮影、咬合法撮影、パノラマX線撮影、頭部一般撮影、診断用(ヘリカル)CTおよび歯科用CBCTと数多く、被ばく線量には幅がある。特に診断用(ヘリカル)CTが高くICRP推奨閾値より低く抑えられているが、被ばく線量は少ない方が望ましい。
