Hi John, hope all is well.
You are correct of course.  I might better have said that correlation 
does not NECESSARILY mean causation (or not the direction of causation. 
  A direct cause of high ferritin might be hemochromatosis. 
Hemochromatosis is often undiagnosed.  My late wife had hemochromatosis, 
she definitely did NOT have periodontitis.  Has that study been done? 
Apparently yes!
