1. is the unattached portion of gingiva that surrounds the tooth in the CEJ region: Free
Gingiva
2. is the gingiva that is continuous with the free gingiva but is tightly bound: Attached
gingiva
3. is the scalloped, linear area that defines the seperation of the attached gingiva
from the alveolar mucosa: mucogingival junction
4. True: Attached gingiva will be the widest in the incisor and molar region and narrowest in the
premolar regions
is defined as a tough fibrous structural protein that occurs in the outer layer of the skin and the
oral epithelium: Keratin
5. - Free gingiva (attached to tooth by JE)
- Attached gingiva (attaches to the cementum and bone by connective tissue)-
: What surfaces in the mouth are keratinized?
6. NO
- the col is located directly apical of the contact between two teeth: Is the gingival col present
if the adjacent teeth are not in contact?
7. a dense bone tissue that makes up the outer surface the mand and max on facial and
lingual aspects
- higher portion of this in the mandibile: Cortical bone (compact bone)
8. lattice-like bone between the cortical and alveolar bone that is surrounded by marrow
- higher portion of this in the maxilla: Cancellous bone (spongy or trabecular bone)
9. The crest of the alveolar process follows the CEJ and in health, should be
apical to the CEJ

PS - the alveolar process is constantly remodeling to accommodate tooth migration and resorbtion
2-3mm
10. is gingival recession, alveolar bone loss, and root exposure - usually v shaped:
Dehiscence
11. a "window" of bone loss bordered by alveolar bone
"Finessing in front of the window": Fenestration
12. are Builders
b=builder: Osteoblasts
13. are bone consumers or destroyers
c=consumer: Osteoclasts
14. is a layer of soft connective tissue that attaches the tooth to the bone in the socket.
PDL mainly consists of fibroblasts but can also include cementoblasts and osteoblasts. The
PDL absorbs mechanical loads: PDL
15.The PDl space ranges from to : 0.05-0.25mm
16. The ends of the PDL fibers that are embedded in the cementum and alveolar bone
includes:
- alveolar crest fibers
- horizontal fibers
- interradicular fibers
- oblique apical fibers: Sharpey fibers of the PDL
17.The purpose of the PDL is to provide:: - Physical support: transmits occlusal forces to bone,
resists impact, protects nerves and vessles
- Formative/ Resorptive support: forms and resorbs cementum, bone and remodels the PDL using
cemtoblasts/clasts, osteoblasts/clasts, or fibroblasts
- Nutritive/Sensory: supplies nutrition to cementum, bone, gingiva, and blood vessels and conducts
nerve sensations
18. is a thin layer of mineralized connective tissue that provides a seal for dentinal
tubules and attaches the PDL to the tooth. It DOES NOT contain blood, nerves, or lymph - it gets
its nutrients from the PDL: Cementum
19.3 types of relationship with CEJ include : - Space: leaves a gap
between cementum and enamel (5-10%)
- Meet/end-to-end : cementum meets at enamel (30%)
