Title

Change "Diastema" and its subtypes to "Clinical findings" from "Disorders"

Version Information

Document review

Statement of problem as requested or initially identified

During review of the Congenital disease subhierarchy, it was noticed that 35591002 |Diastema of teeth (disorder)| was currently modeled as a congenital disorder.  Upon discussion with the Dental SIG it was determined that in many cases Diastema is neither a disorder or congenital.  While tooth spacing may be caused by other diseases, in general, it is not considered a disorder, but a variant of tooth postion.

Revision of 35591002 |Diastema of teeth (disorder)| and its subtypes to reflect current modeling practice and relocation in the clinical findings hierarchy to more accurately reflect its clinical significance

Agreed scope statement

Identify additional changes
None...

Solution proposed
The concepts will be remodeled to the Proximal primitive parent pattern and relationships revised to reflect the current view of the dental SIG

Stakeholder input
The proposed remodeling was discussed at the Dental SIG meeting in London, April 2017

Impact assessment
Minor impact to the structure of the clinical findings hierarchy.  May be some impact on value sets derived from the Congenital malformation subhiearchy as these concepts will no longer be members of that subhierarchy, except where a component of a congenital malformation syndrome

Risk assessment
Unless remodeled, these concepts will continue to be misrepresented as congenital diseases.
