The Planmeca Ultra Low Dose™ protocol has changed 3D imaging completely

“At MESANTIS® 3D DENTAL-RADIOLOGICUM in Germany, the Planmeca Ultra Low Dose imaging protocol is used either with a small or large field of view. Using the new protocol, a lot of patients can benefit from improved 3D diagnostics without being exposed to a higher radiation dose.”

Scientific evidence on the effectiveness of the
Planmeca Ultra Low Dose™ imaging protocol

A new scientific study on Planmeca Ultra Low Dose™ (ULD) by Drs. Ludlow and Koivisto establishes that the low dose imaging protocol enables CBCT diagnosis with a significantly lower dose than standard protocols, without a reduction in image quality. The study’s conclusion states the following:

“An average reduction in dose of 77% was achieved using ULD protocols when compared with standard protocols. While this dose reduction was significant, no statistical reduction in image quality between ULD and standard protocols was seen. This would suggest that patient doses can be reduced without loss of diagnostic quality.” (Ludlow, John Barrett and Koivisto, Juha: Dosimetry of Orthodontic Diagnostic FOVs Using Low Dose CBCT protocol)

As dental imaging continues to evolve, questions regarding reduced doses and patient safety are set to take on an ever increasing role. According to the well-known ALADA principle, imaging doses must be kept as low as reasonably achievable; Patients must not be exposed to a higher dosage than needed to acquire images of sufficient diagnostic quality. The findings in the study indicate that reduced patient doses can be achieved without a loss in image quality by using the Planmeca Ultra Low Dose protocol.
