# Non-SOP condition

Clinical onset

Clinical onset may be based on relevant symptoms (swelling of gums, tendency for gums to bleed) but is more likley to be when first diagnosed by a dentist.

Clinical worsening

The condition is responsive to treatment and to good dental hygeine.  Worsening may be evidenced by an increase in symptoms or assessed based on dental reports.  The development of periodontitis or loss of teeth associated with gingivitis represents onset of a new condition and not worsening of gingivitis.
