Cracked tooth.

Question 13

The cause of localized aggressive periodontitis.

Answer 13

Aggregatibacter actinomycetoconcomitans

Type of occlusal trauma where there’s excess forces on the tooth, but periodontal support is normal.

Answer 14

Primary occlusal trauma

Question 15

Therapy for occlusal trauma.

Answer 15

Occlusal equilibration, splint to equally distribute the occlusal forces.

Question 16

Answer 17

GP

Green or Purple

Question 18

What procedures are performed during a re-evaluation?

Answer 18

• Measure pocket depths.
• Measure plaque with disclosing solution.
• Record BOP.
• Look for calculus

Question 19

What does BOP indicate?

Answer 19

Inflammation

Question 20

Absence of BOP does NOT mean that there’s absence of this.

Answer 20

Inflammation

Question 21

Reasons for continued BOP after initial therapy?

Answer 21
