PERIO817: How to Measure FGM to CEJ with W.H.O Probe & Periodontal/Gingival Health

Probing Pocket Depth (PPD)

distance from the free gingival margin to the base of the pokcet

Clinical Attachment Level/Loss (CAL)

defined as the distance from the cementoenamel junction of the tooth to the base of the pocket.

You must ask the question "Can I see the CEJ?" Is there any bone loss?. If not the FGM - CEJ measurement is at least ___ mm

minus (-) 1 mm

Gingivitis Dental Biofilm Induced by

- Associated with __ __ alone

- Mediated by systemic or local ___ __

- __ gingival enlargement

dental biofilm

risk factors

drug-induced

When is FGM - CEJ = Negative # ?

FGM is coronal to the CEJ

(occurs in health, no bone loss)

When is FGM - CEJ = 0?

FGM is at the CEJ

(may occur with/without bone loss)

When is FGM-CEJ = Positive # ?

FGM is apical to the CEJ

(occurs when bone loss is present and recession )

The ___ mm ball of the WHO "engages" the CEJ

0.5 mm

Mucogingival Pathology

straight buccal and lingual surfaces, not interproximal

Mucogingival Defect

probing to or beyond the mucogingival junction (no attached gingiva)

What is the Attached Gingiva Attached to?

Junctional Epithelium

Connective tissues fibers inserted into the cementum

periosteum/bone

When is a Mucogingival defect necessary for treatment?

progressive recession

interferes with oral hygiene

absence of keratinized tissue

Furcation Involvement

bone loss apical to the area where the roots divide, thus making it accessible to bacteria

What do you use to detect furcation involvement?

Nabers probe

Glickman Class 1

slight bone loss

feel convexity of roots

feel concavity of furcation entrance

no horizontal component

no radiographic changes

Glickman Class II

definite horizonal component

not through and through

radiographic involvement possible

Glickman Class III

bone loss through and through

radiographic evidence

Glickman Class IV

bone loss through and through

clinically can see

radiographic evidence

What stage of Periodontitis must an SRP be done?

Stage III
