Exam 8: Supporting Structures

Interdental papilla is classified as attached gingiva.

The periodontium, composed of tissues that support the teeth, includes which of the following structures (select all that apply)?

Alveolar bone is composed of all of the following EXCEPT one. Which one is the EXCEPTION?

On a radiograph, the alveolar bone that surrounds the tooth is called supraperiosteal bone.

With regard to apposition and resorption, on which tissue are these activities MOST active?

When assessing the health of the gingival unit, which of the following provide guidance to the dental professional (select all that apply)?

The periodontal ligament is constantly undergoing functional change because the fibers are constantly subjected to a variety of pressures exerted on the tooth.

A healthy gingival sulcus should not exceed 2.0 mm in depth.

Each of the following structures is a component of the gingival unit EXCEPT one. Which one is the EXCEPTION?

The gingival transseptal fibers extend from the cementum of one tooth to the alveolar process of adjacent teeth. The oblique gingival fibers are circular bands of connective tissue that surround the teeth.

Each of the following fibers extend from the cementum to the alveolar bone EXCEPT one. Which one is the EXCEPTION?

When teeth are subjected to relatively constant forces tooth mobility is likely to result because forces cause pressure on the root, periodontal ligament, and bone.

Periodontal ligament fibers that extend from the tooth to the alveolar crest are called

Which of the following are functions of the attachment apparatus (select all that apply)?

Important features to consider while evaluating gingival conditions include (select all that apply):

The physical arrangement of bone is permanently fixed. Only externally originated pressure or tension from orthodontic forces cause bone apposition and resorption.

Cementum that is free of embedded cementoblasts is clear and without structure.

Inflammation of the gingival papilla is easily recognized because the area takes on a color that is more red than normal.

Sharpey's fibers can be found in all of the following EXCEPT one. Which one is the EXCEPTION?
