Question 9

8 Determinants of health

Answer 9

Question 10

Gingival sulcus vs pocket

Answer 10

Sulcus indicated health, pocket indicates disease

Question 11

Where is the JE (junctional epithelium) & healthy vs disease

Answer 11

Part of gingiva (gum) that attaches to directly to tooth (in pocket/sulcus)
Healthy - above CEJ
Disease - below CEJ

Question 12

What is the CEJ (cemento-enamel junction)?

Answer 12

Area of union if the cementum and cervical region of tooth (crown and root)

Question 13

Healthy gingival sulcus (mm)

Answer 13

0-3 mm, more than that indicates pocket/ unhealthy

Question 14

Where is periodontal ligament ? Relate to healthy and disease

Answer 14

Attaches cementum (against tooth) to alveolar bone.
Intact in healthy and gingivitis
Destruction in periodontitis

Question 15

Where is gingival fibre? Relate to health and disease

Answer 15

Found within gingiva (help hold gums against teeth)
Intact in health
Some destruction in gingivitis
Destruction in periodontitis
