2 Overview What are cephalometrics? What we are trying to accomplish Two questions for the committee

3 What are Cephalometrics Head X-rays taken in a standardized manner Cephalometrics are measurements on the X-ray itself Mostly consist of lengths and angles Hundreds of cephalometrics have been defined Used by some orthodontists to help with treatment planning Used for research Defined in several cephalometric atlases

9 What we are trying to accomplish Use LOINC term definitions to unify the cephalometric definitions of several cephalometric atlases and analyses.

13 Benefits of LOINC terminology definitions of cephalometrics Unify terms in 10 existing standards for cephalometric definitions (See Ceph Manual) Allow data in this area to be exchanged more easily Benefits our current project by creating a rigorous and legitimate standard form for future case donations:

14 Question One Should we define LOINC terms for landmarks (point) definitions and then embed these in angle and plane measurements’ terms? (I don’t know if there is a “point” measurement type currently defined in LOINC.) See page 2 of our Cephalometric Manual for “standard” point definitions

15 Question Two Can we or should we incorporate the cephalometric parameter diagrams into the LOINC database? Current text fields in RELMA are limited in length and it is difficult (but still possible) to reference up to five sources for a given cephalometric term
