Digital volume tomography (DVT)

The digital volume tomography is an X-ray computed tomography which allows three-dimensional imaging of the examined tissue. Due to the cone beam technique there’s less radiation exposure compared to the older computed tomography (CT). Nonetheless, a high-resolution DVT still has a multiple of the radiation exposure of conventional orthodontic X-rays like OPG or Ceph. In orthodontics DVT is used to detect retained or redundant teeth. On the other hand, patients should pay attention if doctors take DVTs from all patients: There’s no justification for it!
