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

Peridontal Ligament

Gingiva

Cementum

Alveolar Mucosa

During mastication, the tooth is cushioned from occlusal forces by the:

Periodontal Ligament

Gingiva

Cementum

Alveolar /

Which part of the periodontium may become damaged after years of periodontal intrumentation?

Periodontal ligament

Cementum

Gingiva

Alveolar

Lattice-like bone that fills the interior portion of the alveolar process refers to:

Cortical bone

Cancellous bone

Periosteum

Cribiform plate

In health, the alveolar crest covers the cementoenamel junctions of the teeth.

True

False

Which of the following is a mesh-like material that surrounds the cells and provides a framework?

Extracellular matrix

Mast cell

Nucleus

Collagen fiber bundle

What structure forms the base of a periodontal pocket?

Basal epithelium

Sulcular epitherlium

Junctional epithelium

Oral epithelium

This demarcation is a shallow linear depression that seperates the free and attached gingiva

Free gingival groove

Mucogingival junction

Gingival margin

Alveolar mucos

All of the following are functions of gingival fibers EXCEPT:

They connect adjacent teeth to one another to control tooth position

They unite free gingiva with cementum of the root

They prevent plaque biofilm from entering the gingival connective tissue

. They provide rigidity needed to withstand frictional forces during chewing

All of the following are functions of the periodontal ligament EXCEPT:

It unites free gingiva with cementum

It attaches the tooth to the bony socket

It provides sensory and nutritive function

It produces osteoclasts to resorb bone

The ends of periodontal ligament fibers (brush-like) that embed in bone and cementum are known as:

Interradicular fibers

Oblique fibers

Horizontal fibers

Sharpey's fibers

The characteristics of periodontitis may include which of the following:

Loss of alveolar bone

Destruction of the gingival and PDL fibers

All of the above

Apical migration of the junctional epithelium

What is the most common pattern of bone loss?

Horizontal

Vertical

Oblique

Interproximal

What is the difference between a gingival and a periodontal pocket?

Gingival pocket is a true pocket, perio is a false pocket

A periodontal pocket does not have exudate

A gingival pocket is f/ inflammation, perio pocket f/ migration of the JE

A gingival pocket is from horizontal bone loss, perio from vertical

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

Junctional epithelium

Periodontal ligament

Gingival sulcus

Interdental gingiva
