The notation system used by dentists referring patients to ManchesterDentalHospital was recorded. A questionnaire was sent to the Deans of all Dental Schools in the UK and letters of referral to Manchester Dental Hospitals Paediatric GA Service were monitored for 1 month. The results showed that only ManchesterUniversityDentalSchool used the FDI system but 6 other schools instructed students in its use. -Source
