Q

Gingival crevicular fluid GCF

A

A serumlike fluid secreted from underlying connective tissue into the sulcular space, little or no fluid is found in a healthy gingival sulcus. But can flow 1 day after no oral biofilm control

Q

Alveolar crest

A

Alveolar bone located between the teeth

19
Q

Periodontal endoscope

A

Illuminated fiberoptic instrument that provides high magnification views of the gingival sulcus or perio pocket

20
Q

Dental biofilm-induced gingivitis

A

Is inflammation of the gingival tissue and a reversible bacterial infection confined to the gingival tissue

21
Q

What occurs in gingivitis?

A

Free gingiva shows signs of inflammation, but no apical migration of the JE has occurred beyond the CEJ, no evident bone loss

22
Q

What are the three clinical features of necrotizing periodontal diseases?

A

papillary necrosis
bleeding
pain

23
Q

Gingival recession

A

Apical migration of the margin of the gingiva causing root exposure

24
Q

Traumatic Occlusal Force

A

Any occlusal force that damages the teeth or periodontal attachment tissues

25
Q

Occlusal trauma

A

Injury to the periodontium

26
Q

Supracrestal attached tissues

A

Formerly biologic width, are the JE and connective tissues that attach the gingiva to the alveolar bone above the crest of the bone

27
Q

Periodontal abscess

A

Localized periodontal infections that result in inflammation and can ultimately lead to the formation of purulent exudate

28
Q

Purulent exudate

A

Containing pus

29
Q

What are osseointegrated dental implants monitored for?

A

peri-implant health, peri-implant mucositis, peri-implantitis, or peri-implant soft and hard tissue deficiencies

30
Q

Peri-implant health

A

The absence of redness (erythema), swelling (edema), bleeding, and suppuration of tissues surrounding the implant.

31
Q

Peri-implant mucositis

A

Inflamed gingival tissue surrounding a dental implant and is characterized by redness, bleeding, swelling, and/or suppuration, slightly deeper PD is possible due to tissue enlargement from inflammation rather than bone loss

32
Q

Peri-implantitis

A

A dental biofilm-induced disease that can also be caused by placement or surgical trauma. Characterized by same inflammatory signs as peri-implant mucositis, and also has progressing alveolar bone loss

33
Q

Peri-implant soft and hard tissue deficiencies

A

Reduced dimensions of the alveolar bone or ridge that occur during the healing process after tooth loss

34
Q

Psuedopocket

A

Artificially deepened sulcus caused by the marginal gingiva moving coronally not apically from inflammation

35
Q

Probing depth

A

Distance from gingival margin to the base of sulcus/pocket

36
Q

Periodontal pocket

A

Pathologically deepened sulcus

37
Q

Suprabony periodontal pocket

A

occurs when JE has migrated below CEJ but remains above crest of alveolar bone, commonly associated with horizontal bone loss

38
Q

Intrabony periodontal pocket

A

occurs when JE migrates below the crest of the alveolar bone, commonly associated with vertical bone loss

39
Q

Clinical Attachment Loss CAL

A

The position of the attached periodontal tissues at the base of the pocket, determined by comparing GM distance from CEJ with distance from base or pocket

40
Q

Furcation involvement

A

Loss of interradicular bone and PDL attachment of multirooted teeth

41
Q

Tooth mobility

A

Degree to which a tooth can move horizontally or apically, 3 grades

42
Q

Fremitus

A

Vibration or movement of teeth when in contacting positions from the patient’s own occlusal forces

43
Q

PSRs

A

Periodontal Screening and Recording, codes 0-4
