Exam 8: Supporting Structures

MATCHING Evaluation,diagnosis,and treatment of gingival and periodontal conditions require a sound understanding of the structure of the gingival unit and periodontal attachment apparatus.Match the gingival structure with its corresponding description. -Free gingiva

The periodontal ligament provides a hammock of tissue bundles that support the tooth within bone.Each of the following is true regarding the periodontal ligament EXCEPT one.Which one is the EXCEPTION?

Which is a gingival fiber?

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

Interdental papilla is classified as attached gingiva.

Bundle bone is the collection of numerous layers of bone added to the socket wall through apposition.Because it is relatively new bone,it has no attachment with the periodontal ligament.

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

MATCHING Evaluation,diagnosis,and treatment of gingival and periodontal conditions require a sound understanding of the structure of the gingival unit and periodontal attachment apparatus.Match the gingival structure with its corresponding description. -Melanin

MATCHING Evaluation,diagnosis,and treatment of gingival and periodontal conditions require a sound understanding of the structure of the gingival unit and periodontal attachment apparatus.Match the gingival structure with its corresponding description. -Alveolar mucosa

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

The thin,soft,smooth alveolar mucosa is highly keratinized.The thicker,stippled attached gingiva is keratinized,contains rete pegs,and is covered with stratified squamous epithelium.

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

Orthodontic movement is possible due to which of the following (Select all that apply. )?

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

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

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

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.

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.
