Answer 20

functional, surrounds, supports

Question 21

covers bone and surrounds the teeth at cervical areas; function is both protective and supportive

Answer 21

gingiva

Question 22

the various tissues that surround and support the teeth; includes the cementum, periodontal ligament, and alveolar process.

Answer 24

attachment apparatus

Answer 38

edema, soft/spongy (advanced disease = fibrotic)

Question 39

unhealthy gingiva texture

Answer 39

loss of stippling (advanced = fibrotic)

Question 40

unhealthy gingiva bleeding tendency
