What N is probing force?

0.2-0.5 N

Deepening of the gingival sulcus as a result of an increase in the size of the gingiva with no apical migration of the junctional epithelium or loss of alveolar bone.

Gingival pocket (pseudo pocket)

Deepening of the gingival sulcus with destruction of the adjacent gingival fibers, periodontal ligament, and crestal alveolar bone with apical migration of the junctional epithelium.

Suprabony pocket

Deepening of the gingival sulcus to a level at which the bottom of the pocket and the junctional epithelium are apical to the crest of the alveolar bone

Infrabony pocket

Increase probing depth of greater than 1mm had a positive predictive value of what?

68% at 42 months

An increase probing depth of 1mm and bleeding on probing had a positive predicitve value of what?

75% at 42 months

Furcation Glickman Grade system:

• 1?

• 2?

• 3?

• 4?

1. Pocket formation into the flute but intact interradicular bone

2. Loss of interradicular bone and pocket formation of varying depths into the furcation but no completely through to the opposite side

3. Complete loss of interradicular bone with pocket formation that is completely probable to the opposide side of the tooth

4. Loss of attachment and recession, rendering the furca completely visible to the eye

The shorter the root trunk, the less _______needs to be lost before the furcation is involved.

attachment

Miller Index Classification:

• Class 1?

• Class 2?

• Class 3?

Mobility greater than normal

Up to 1mm in any direction (

More than 1mm in any direction ± vertical depression

how much can a normal tooth move?

0.2mm any direction

Varies tooth by tooth and day by day

What are the 3 reasons for increased mobility?

1. Alveolar bone loss (periodontitis)

2. Occlusal trauma (Widening of the PDL space)

3. Endodontic lesion (periapical lesion)

Random facts:

• Teeth that are mobile have deeper ________

• Mobile teeth don’t respond well to ________ tx

• ________ adjustment may enhance perio tx

pockets

perio

occlusal

What does BOP tell us?

Inflammation is present, it does not mean the site willl loose attachment but its chances increase and if it doesnt bleed rarely will there be attachment loose

Suppuration is found 3-5% of _________ _________sites

perio disease

Can be stabilized with comprehensive periodontal treatment maintenance, and with less chance of future breakdown

Favorable

Influenced by local and or systemic factors that may or may not be controlled; periodontium can be maintained with proper care

Questionable

Influenced by local and or systemic factors that cannot be controlled

Unfavorable

Must be extracted

Hopeless

If prosthetic treatment needed:

• Favorable and questionable?

• Unfavorable and Hopeless?

Periodontal stability

Extraction

When a tooth with RCT shows a single deep pocket be warned of what?

Root fracture

The prevelance of overhanging margins is in a range from ________ of restored surfaces in _________ of the patients

25%-76%

32%-90%

________ _______ are correlated with food impaction, and food impaction is correlated to deeper probing depths

open contacts

The smaller the interraciduclar distance the higher risk for what?

Alveolar bone disease

Where are Cervical enamel projetions mosst common?
