Chapter 20 - D & W (Week 5)

Destruction of the periodontium results from two distinct components: _______________ periodontal pathogens and the ____________ mediated response. Choose the option that best fills in the blanks.

gram negative; host

Vasoconstriction followed by migration and infiltration of PMNs into JE and gingival sulcus occurs at what stage of periodontal disease?

inital lesion

Healthy gingiva, when visually examined, air dried, and probed,

does not bleed or exlude fluids

The gingiva has a protective layer of stratified squamous epithelium covering a dense, fibrous connective tissue. Gingiva is divided into four anatomic areas: (1) free or unattached gingiva; (2) gingival sulcus; (3) attached gingiva; and (4) interdental gingiva or interdental papilla.

both statements are true

The term pseudopocket or gingival pocket is a condition of which of the following periodontal diseases?

gingivitis

Documentation of periodontal assessment findings at every visit is essential for accurate periodontal disease and risk management. Which of the following should be included in chart notations?

all are right

The causes of gingival recession are many. Once gingival recession exposes the root surface, the connective tissue cannot reattach. Which one of the following is the correct reason that the tissues cannot reattach?

exposed collagen breaks down

The clinician bases risk factor assessment on information obtained through all but which one of the following?

financial statements

Each of the following is a valid reason for noting sensitivity on a dental chart EXCEPT one. Which is the EXCEPTION?

increased office profits by recommending products for sale

Which of the following indicate healthy periodontium?

Attached gingiva may have a stippled, orange peel appearance.

Periodontal diseases are inflammatory processes characterized by an accumulation of which cells?

all are correct

Radiographically determining changes in the alveolar bone associated with periodontal disease is based on the appearance of which of the following?

both crestal lamina dura and alveolar bone

Furcation involvement is the loss of interradicular bone and the attachment of multirooted teeth. Radiographs confirm but do not always accurately detect or reveal this condition.

both are true

Which of the following radiographic images or techniques is recommended for evaluating bone loss in periodontal disease?

vertical BW

Which are important factors in the relationship between smoking and loss of attachment?

length of time smoking

Radiographic images are a record of the patient's periodontal status, showing which of the following:

history of disease progression

The angle at which a radiograph is taken can show more interradicular bone between the roots of teeth than is actually present. If the radiographic image shows no radiolucency in the furcation area, the clinician can be assured there is no interradicular bone loss.

first is false, second is true

Modifiable risk factors for periodontal disease include all of the following EXCEPT which one? (Select all that apply.)

age

Mr. Sands was previously treated for generalized gingivitis. During his successive re-care visits, the dental hygienist has recorded fewer sites of BOP and reduced gingival enlargement. He tells the hygienist that he is using the instructed oral health aids at least twice a day. Which of the following has most likely occurred?

the JE is no longer ulcerated

Each of the following is a radiographically evident sign of periodontal breakdown EXCEPT one. Which is the EXCEPTION?

The crestal lamina dura is 1.5-2 mm apical and parallel to the CEJ.

Clinical attachment loss (CAL) is determined by measuring from the gingival margin to the base of the periodontal pocket and also measuring from the CEJ to the free gingival margin. If the pocket depth is measured at 5 mm and the recession is measured at 2 mm, what is the correct CAL?

7 mm

Gingival tissues of smokers and long-term chronic inflammation may show minimal signs of inflammation and bleeding. Deep periodontal pockets always exhibit obvious signs of inflammation and bleeding.

first is true, second is false

During periodontal probing, which of the following best describes the rationale for walking the periodontal probe subgingivally in 1-mm increments?

depth of JE attatchment varies

Each of the following is a local risk factor for periodontitis EXCEPT one. Which is the EXCEPTION?

cariogenic beverages
