All of the following are true of oral epithelium, EXCEPT:
a. It may be keratinized or parakeratinized
b. The junction with connective tissue in health has a wavy
interface c. It is permeable, allowing for flow of crevicular fluid
d. It covers the outer surface of free gingiva and attached gingiva - ✔c. It is
permeable, allowing for flow of crevicular fluid
All of the following are functions of the periodontal ligament EXCEPT:
a. It attaches the tooth to the bony socket
b. It provides sensory and nutritive function
c. It unites free gingiva with cementum
d. It produces osteoclasts to resorb bone - ✔c. It unites free gingiva with cementum
The ends of periodontal ligament fibers that embed in bone and cementum are known as:
a. Interradicular fibers
b. Sharpey fibers
c. Rete pegs
d. Endpoint fibers - ✔b. Sharpey fibers
The sequence of events that occurs during the development of periodontal disease is termed:
,a. Pathogenesis
b. Coronal migration of the junctional epithelium
c. Infrabony pocket formation
d. Histology - ✔a. Pathogenesis
A patient exhibits a bacterial infection of all parts of the periodontium. Which of the following is
the state of her periodontium?
a. Health
b. Gingivitis
c. Pathogenesis
d. Periodontitis - ✔d. Periodontitis
A patient exhibits swollen, red gingival tissues with no bone loss. The hygienist records
"periodontal disease" in the patient chart. Is this notation accurate?
a. No, because this patient has gingivitis, not periodontal disease
b. No, because there is no bone loss so this cannot be periodontal disease
c. No, since the patient has no bone loss the periodontium is healthy
d. Yes, because gingivitis is a periodontal disease - ✔d. Yes, because gingivitis is a
periodontal disease
Your patient has not been to the dentist in 2 years. When examining the gingival tissues, you
note that the gingival margin is swollen and covers the gingival third of the tooth crowns. In
addition, there is marginal redness with slight bleeding on probing. Probing depths range from
1 to 4 mm. There is no bone loss present. How would you label the state of this patient's
periodontium?
a. Healthy, considering it has been 2 years since the patient's last maintenance visit
,b. Gingivitis
c. Early periodontitis because some probing depths were over 3 mm
d. There is not enough information to make a determination - ✔b. Gingivitis
All of the following are characteristics of periodontitis EXCEPT:
a. In periodontitis, the gingival margin does not adapt closely to the tooth
b. Interdental papillae may not fill the embrasure spaces if the patient has periodontitis
c. With periodontitis, there may be bleeding upon gentle probing
d. The tissue damage in periodontitis is reversible---the body can repair the damage - ✔d.
The tissue damage in periodontitis is reversible---the body can repair the damage
A patient's gingival margin is at the cementoenamel junction. There is no bleeding upon
probing. Microscopically, the junctional epithelium is apical to the cementoenamel junction
on cementum. Which of the following is the state of his periodontium?
a. Health
b. Gingivitis
c. Alveolar necrosis
d. Periodontitis - ✔d. Periodontitis
Which type of bone loss creates infrabony pockets?
a. Interdental bone loss
b. Horizontal bone loss
c. Vertical bone loss
d. Circumferential bone loss - ✔c. Vertical bone loss
, The difference between a gingival pocket and a periodontal pocket is that:
a. A gingival pocket is a result of gingival enlargement, and a periodontal pocket is a result of
apical migration of junctional epithelium and alveolar bone loss
b. A gingival pocket does not have exudate, and periodontal pocket exhibit exudate
c. A gingival pocket occurs when there is horizontal bone loss, and a periodontal pocket
occurs when there is vertical bone loss
d. A periodontal pocket is a "false" pocket while a gingival pocket is a "true" pocket - ✔a. A
gingival pocket is a result of gingival enlargement, and a periodontal pocket is a result of apical
migration of junctional epithelium and alveolar bone loss
Risk factors associated with periodontal disease include all of the following EXCEPT:
a. Heredity
b. Personal behaviors
c. Gender
d. Traumatic injury - ✔d. Traumatic injury
Your assessment findings for a patient include: pink gingiva, moderate plaque biofilm, and
probing depths of 6 to 8 mm. How would you classify his disease status?
a. Health
b. Gingivitis
c. Stage I periodontitis
d. Stage III periodontitis - ✔d. Stage III periodontitis
If your patient presents with a gingival reactive infection to a popcorn kernel in the sulcus
on facial of tooth #30, it is not considered a true gingival disease. Pocket depths must be
more than 7 mm deep to be considered severe periodontal lesions.
