Pathogenesis of Periodontal Disease 2 Flashcards
2 causes of pathologic migration of teeth
A. Tongue-thrusting habits
B. Loss of posterior teeth
This is a feature of acute inflammation of the periodontal ligament
Sensitivity to percussion
Plaque and calculus is most common in?
A. Lingual of mandibular incisors
B. Buccal of maxillary molars
2 basic types of gingival tissue response
A. Edematous
B. Fibrotic
This gingival tissue response is smooth, glossy, soft gingiva and is usually seen in acute inflammation
Edematous
This gingival tissue response is firm, stippled, opaque, thicker, more rounded margins and is seen in chronic inflammation
Fibrotic
This is the gold standard for periodontal assessment
Pocket probing
2 types of pocket depths
A. Biologic depth
B. Probing depth
This type of pocket depth is from gingival margin to the junctional epithelium
Biologic depth
This type of pocket depth is where the probe can enter/ reach only
Probing depth
This is the distance between the base of the pocket and a fixed point, usually CEJ
Level of attachment
This is the distance between the base of the pocket to the gingival margin; gingival overgrowth produces higher readings
Pocket depth
2 types of periodontal pockets
A. Pseudo-pocket
B. Real pocket
This is the fake pocket; present when there is gingival growth; no bone loss or clinical attachment loss
Pseudo-pocket
This type of pocket has loss of alveolar bone and loss of clinical attachment
Real pocket
4 uses of periodontal probes
A. Used to measure pocket depth
B. Quantification of bacterial plaque and gingival inflammation
C. Determination of mucogingival relationship
D. Measurement of gingival recession
Images taken from the radiograph can be manipulated on the computer screen to adjust its density, contrast, and magnification
Digital radiography
4 importance of radiography in periodontics
A. Diagnosis periodontal disease
B. Estimation of severity
C. Determination of prognosis
D. Evaluation of treatment outcome
This is a thin radiopaque line adjacent to the periodontal ligament
Lamina dura
In this bone defect, its radiographic appearance is a break or fuzziness at the crest of the interdental alveolar bone
Early bony changes
In this bone defect, its radiographic appearance is a presence of finger-like radiolucent projection into the interdental alveolar bone
Early bone changes
In this bone defect, its radiographic appearance can be measured from a plane that is parallel to a tooth-to-tooth line drawn from the CEJ’s of adjacent teeth
Horizontal bone loss
In this bone defect, its radiographic appearance is seen as more bone loss on the interproximal aspect of one tooth than on the adjacent tooth
Vertical bone loss
In this bone defect, its radiographic appearance are radiolucent areas due to bone loss
Bone defects
