Den 7136 Final Study SetWhat is the most common pattern of bone loss in periodontal disease? ANS✔✔ horizontal bone
loss
What occurs in horizontal bone loss? ANS✔✔ The bone is reduced in height, but the bone margin
remains approximately perpendicular to the tooth surface.
How are angular defects classified? ANS✔✔ on the basis of the number of osseous walls
How many walls can angular defects have? ANS✔✔ one, two, or three walls
Vertical defects appear most often on what tooth surfaces? ANS✔✔ the distal and mesial surfaces
What angular defect has the best chance of recovery? ANS✔✔ 3-walled defect
_____________ bone loss is amenable to regenerative periodontal surgery using a variety of bone
graft materials, bioactive molecules, and membranes ANS✔✔ Vertical
What are clinical signs that suggest the presence of periodontal pockets? ANS✔✔ - a bluish red
gingiva
- thickened marginal gingiva
- gingival bleeding and/or suppuration
- tooth mobility
- diastema formation
- And may be symptoms such as localized pain or pain "deep in the bone."
What is the only reliable method of locating periodontal pockets and to determining their extent?
ANS✔✔ careful probing of the gingival margin along each tooth surface
, As inflammation spreads __________ to involve the connective tissue apical to the junctional
epithelium, gingivitis then becomes periodontitis ANS✔✔ apically
What debris is typically found in periodontal pockets? ANS✔✔ - microorganisms and their
products, enzymes
- endotoxins, and other metabolic products
- gingival fluid, food remnants, salivary mucin, desquamated epithelial cells, and leukocytes
What is found in purulent exudate (pus) if it is found in the oral cavity? ANS✔✔ living,
degenerated, and necrotic leukocytes; living and dead bacteria; serum; and a scant amount of fibrin
Does pus in the oral cavity/pocket indicate the depth of the pocket or the severity of the destruction
of the supporting periodontal tissues? ANS✔✔ no
What becomes a possible reservoir for reinfection of the area after periodontitis treatment?
ANS✔✔ the roots
(Sensitivity to cold may occur, as a result of exposed root dentine, until secondary dentin is formed
by the pulp tissue)
Periodontal pockets go through periods of _______________ and ________________, resulting from
episodic bursts of activity followed by periods of remission ANS✔✔ exacerbation and quiescence
How are periods of quiescence in the periodontal tissues characterized? ANS✔✔ by a reduced
inflammatory response and little or no loss of bone and connective tissue attachment
Periodontal pockets are painless, however, the spread of infection to the __________ from
periodontal pockets may occur, through either the apical foramen or the lateral pulp canals, which
may give rise to painful symptoms ANS✔✔ pulp
