A patient has a healthy periodontium. If the hygienist could see the microscopic structures of this patient's periodontium, how would the interface of the junctional epithelium with the gingival connective tissue appear?

It would have a smooth interface.

It would have a parallel interface.

It would have a sloping interface.

The difference between a gingival pocket and a periodontal pocket is that:

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

A gingival pocket does not have exudate, and periodontal pocket exhibit exudate

A gingival pocket occurs when there is horizontal bone loss, and a periodontal pocket occurs when there is vertical bone loss

A periodontal pocket is a "false" pocket while a gingival pocket is a "true" pocket

All of the following are functions of the periodontal ligament EXCEPT which one?

It unites the free gingiva with the cementum.

It attaches the tooth to the bony socket.

It provides sensory and nutritive function.

It produces osteoclasts to resorb the bone.

All of the following are functions of the cementum EXCEPT which one?

It seals (covers) the dentinal tubules.

It attaches periodontal fibers to the tooth.

It lines the bony sockets and protects the roots of the teeth.

It compensates for the loss of the tooth tissue caused by attrition.

The difference between a desmosome and hemidesmosome is that:

a desmosome connects two cells together, and hemidesmosomes connects a cell to the basal lamina

a desmosome is found in the gingival epithelium, and hemidesmosome is found in connective tissue

a desmosome connects a cell to the basal lamina, and hemidesmosome connects one cell to another

A desmosome is found in connective tissue, and hemidesmosome is found in gingival tissue

When performing a clinical examination on your patient, you note that her gingival tissues are light pink with scalloped margins. There was no bleeding upon probing. Probing depths range from 1-2 mm in depth with no bone loss present. Which of the following is the state of her periodontium?

Gingival health on an intact periodontium

Gingival Health on a reduced periodontium

Which of the following is a classification of periodontal disease that involves infection or death of dental pulpal tissues?

Periodontitis associated with endodontic lesions

. Necrotizing periodontal disease

All of the following are “good” reason for classifying periodontal diseases EXCEPT:

. To determine the fee that the patient should be charged

Present accurate information to the patient about the condition of their periodontium

Communicate clinical findings accurately and universally to other dental providers

Formulate individualized treatment plan

All of the following are true of the oral epithelium, EXCEPT:

It is permeable allowing for flow of cervical fluid

It may be keratinized or parakeratinized

. The junction with connective tissue in health has a wavy interface

it covers the outer surface of free gingiva an attached gingiva

The importance of assessing calculus deposits on teeth during a comprehensive periodontal assessment is which of the following?

Calculus deposits must be removed during nonsurgical therapy.

Calculus is a local contributing factor in disease.

Calculus deposits are a necessary factor for the initiation of periodontal disease.

calculus deposits must be removed during nonsurgical therapy, and calculus is a local contributing factor in disease

All of the following are true about detecting calculus deposits on a radiograph EXCEPT

Radiographic evidence of calculus is an accurate assessment tool for the detection of all calculus deposits

Only large calculus deposits usually are evident on radiographs

Deposits on the facial or lingual can be seen when severe bone loss is present

The ability to see the calculus depends on the degree of mineralization of the deposit

Which of the following statements is true about viewing periodontal pockets on radiographs?

A periodontal pocket is not visible on radiographs

A periodontal pocket appears radiolucent on radiographs

A periodontal pocket appears radiopaque on radiographs

A periodontal pocket is less deep than it appears on a radiograph

One critical component of Necrotizing Periodontal Disease (NPD) is advanced age. NPD is more commonly found in the 40 years and older age group.

The first statement is true; the second statement is false

The first statement is false; the second statement is true

A palatolingual groove can enhance plaque retention thereby contributing to initiation of periodontal disease. Poorly fitting orthodontic appliances have been known to initiate periodontal disease.

The first statement is true; the second statement is false

The first statement is false; the second statement is true

Which of the following lymph nodes drain most of the periodontal tissues?

Innervation of the teeth and periodontal ligament of the maxillary arch is from the alveolar nerves, and innervation of the teeth and periodontal ligament of the mandibular arch is from the alveolar nerves.

The ____ is the part of the mucosa that surrounds the cervical portions of the teeth and covers the alveolar processes

Which of the following tissues is NOT part of the periodontium?

A dental hygienist inserts a calibrated periodontal probe into a healthy sulcus until the tip reaches the base of the sulcus. What anatomical structure forms the base of the sulcus?

While assessing the gingival tissue, the hygienist notes there appear to be "open spaces" apical to the contact areas of many of the patient's teeth. Which anatomical area of the gingiva is missing resulting in open spaces?

The coronal-most edge of the gingiva is the alveolar mucosa. Alveolar mucosa is distinguished by its dark red color and smooth, shiny surface.

What shallow linear depression separates the free and attached gingiva?

The space between the free gingiva and tooth surface is called:

The depth of a clinically normal gingival sulcus is no greater than:
