16.5 Taking the Ceph

16.5.1 Assigning the Participant a Ceph Number

• New cephs are assigned the next sequential number available in the Ceph Log. This number is also burned into the x-ray with a lead plate in the dental school, along with the date of the film.
• Follow-up cephs are always assigned their original ceph number, with an “R” for 1st follow-ups, a “3” for Time 3, a “4” for Time 4 etc.
• It is the responsibility of the technician to track the ceph throughout the entire process.
• An x-ray film without a number burned into it is unusable and indistinguishable from all others.
