There is no authoritative information on how much radiation is emitted from dental CT, but the radiation produced during dental CT examinations is generally small, usually 0.005msv. Although there is no definitive clinical information on how much radiation is emitted from dental CT, when examiners undergo dental CT, the area examined is usually the head and face, so the scope of the examination is relatively small. In addition, the radiation generated by dental CT is generally 0.005msv, which is relatively small compared to whole-body CT. The radiation generated during dental CT examination is relatively small, and it is recommended that the examiner should not be overly worried when undergoing dental CT examination. In addition, although dental CT does not emit much radiation, it is not recommended for women to undergo dental CT during pregnancy to avoid adverse effects on the development of the fetus.
