recession exten-
11.Is junctional epithelium keratinized or non- keratinized?: Non-keratinized
12.What is the function of junctional epithelium?: Encircles the tooth to form a tight seal

gingiva
15.What tissue is loosely attached to the underlying bone?: Alveolar mucosa
16.What gingival fiber group runs from the cementum in the cervical region into the free gingiva to
give support to the gingiva: Dentinogingival fibers
17.What gingival fiber group runs from the alveolar crest into the free and attached gingiva to
provide support?: Alveologingival fibers

, DH 372 Exam 3 (Final)
18.What gingival fibers are continuous around the neck of the tooth to help to maintain the tooth
in position?: Circumferential fibers
19.What gingival fibers run from the cervical cementum over the alveolar crest to blend with fibers of
the periosteum of the bone?: Dentoperiosteal fibers
20.What gingival fiber group runs from the cervical area of one tooth across to an adjacent tooth
(mesial or distal only) to provide resistance to separation of teeth?: Transseptal fibers
21.What principal fiber group extends from the root apex to adjacent sur- rounding bone to
resist vertical forces?: Apical fibers

resist intrusive forces?: Alveolar crest fibers
25.What principal fibers run from cementum between roots of multi- rooted teeth to the adjacent
bone to resist vertical and lateral forces?: Interradicular fibers
26.What is the connective tissue that surrounds and attaches the alveolar bone to cementum?:
PDL
27.The PDL inserts into cementum through what fibers?: Sharpey's fibers
28.What type of cementum is in the cervical 2/3 and serves as a place for attachment? Acellular
or cellular?: Acellular

: Cellular
30.What is the specialized part of the mandible and maxilla with a primary function to support the
teeth?: Alveolar bone
31.What bone undergoes rapid and continual remodeling?: Alveolar
32.What bone resorbs in edentulous areas?: Alveolar
33.What is the primary etiological factor of periodontal disease?: Pathogenic microbiomes (made
up of subgingival biofilms)
34.What are modifiable risk factors of perio disease?: Tobacco, diabetes, meta- bolic syndrome,
obesity, alcohol, diet, psychological factors, medications
35.how much does alcohol increase the risk for perio disease?: doubles the risk in females and
25% in males
36.What does alcohol do to the immune system?: Impairs it
37.How does alcohol affect the metabolic functions of homeostasis?: Alters it
