Question 1: Which teeth have wide attached gingiva? narrow?

Answer:

*wider-incisor & molar *narrow-premolar Question 2: In what structure are the periodontal ligament fibers embedded on the tooth side?

Answer:

cementum

Question 3: What part of the tooth may be easily confused with calculus?

Answer:

cementum

Question 4: What is the periodontium innervated by?

Answer:

branches of trigeminal nerve

Question 5: What are the TEETH & PDL of the maxillary arch innervated by?

Answer:

trigeminal nerve?maxillary div?superior alveolar nerve (?asa, msa, psa)

Question 6: What is the coronal boundary or upper edge of gingiva called?

Answer:

gingival margin

Question 7: Which lymph nodes drain the palatal gingiva of the maxilla?

Answer:

deep cervical lymph nodes

Question 8: What is the function of cementum?

Answer:

*anchors pdl to tooth *protects dentin & seals end of dentinal tubules *compensates for tooth wear by forming new cementum

Question 9: Where is buccal cortical bone thin? Thick?

Answer:

*thin-incisor, canine premolar region *thick-molar region

Question 10: What type of gingiva is the col? Where is it located?

Answer:

*attached gingiva *just below the contact areas

Question 11: Is the col present in adjacent teeth that do not touch?

Answer:

no Question 12: Which lymph nodes drain the gingiva in the region of the mandibular incisors?

Answer:

submental lymph nodes

Question 13: When would alveolar bone not be present?

Answer:

*when teeth are extracted alveolar bone resorbs *if teeth do not erupt it does not develop

Question 14: Which lymph nodes drain the gingiva in the third molar region?

Answer:

jugulodigastric lymph nodes

Question 15: Define alveolus.

Answer:

bony socket; cavity in the alveolar bone that houses the root of a tooth Question 16: T/F Cementum does not have its own blood supply; it receives its nutrients from the periodontal ligament.

Answer:

True Question 17: Name the vascular supply of the maxillary teeth, gingiva, pdl & alveolar bone.

Answer:

*ASA & PSA arteries *infraorbital artery *greater palatine artery *nasopalatine artery

Question 18: What causes the gingiva to appear stippled?

Answer:

presence of connective fibers that attach it to cementum & bone

Question 19: What is the GINGIVA of the maxillary arch innervated by?

Answer:

trigeminal nerve?maxillary div?*superior alveolar nerve(?anterior, middle & posterior branches) *infraorbital nerve *greater palatine nerve *nasopalatine nerve

Question 20: What is the periodontium?

Answer:

functional system of tissues that surrounds the teeth and attaches them to the jawbone.

Question 21: What is the gingiva that is connected to the cementum called? Describe it's location.

Answer:

*attached gingiva *lies between the free gingiva & alveolar mucosa Question 22: Which tissue of the periodontium may be pigmented in dark skinned individuals?

Answer:

attached gingiva Question 23: T/F Healthy gingival tissue always has a dimpled appearance known as stippling.

Answer:

False (it may or may not) Question 24: T/F Cementum is not necessary to the health of the periodontium because the underlying dentin will protect the root if the cementum is removed by toothbrush abrasion or from dental procedures.

Answer:

False

Question 25: Does the gingiva connect the tooth to the socket?

Answer:

no, the PDL does

Question 26: What forms the base of a gingival sulcus?

Answer:

junctional epithelium

Question 27: What is the thin layer of bone that lines the tooth socket?

Answer:

Alveolar bone proper

Question 28: Name the four anatomic areas of the gingiva.

Answer:

*free gingiva *gingival sulcus *interdental gingiva *attached gingiva
