|
|

Indices of
gingivitis

|
|
– |
Indices of
periodontal involvement alone – loss of

|
|
attachment (LOA)
or pocket depth
|
|
|
|
• |
Or combined with
measures of gingivitis
|
|
|
|
– |
Also digital
radiography and enzymatic tests to detect
|
|
|
specific
microorganisms

None of these
measures appropriate to collect surveillance data
