The MPE provides advice on, for example, the measurement and optimisation of patient dose, the application and use of Dose Reference Levels (DRLs) selection of suitable x-ray equipment and ancillary equipment and equipment quality assurance.

Refer to the ‘Guidance Notes for Dental Practitioners on the Safe Use of X-ray Equipment’  for full details of what is to be included in the scope of advice provided.
