Answer 10

5 days

Question 11

When calculus develops

Answer 11

10-20 days

Avg. is 12 days

Question 12

How long does it take for mineralization to occur?

Answer 12

24-48 hours

Question 13

Malocclusion

Answer 13

Anything that isn’t the biologically normal bite

Question 14

Difference between periopocket and gingival pocket

Answer 14

• Period pocket is caused by a disease or degeneration and involve deeper structures such as the PDL, Cementum, and the bone. Tooth wall is cementum and Perio pockets may be Suprabony or infrabony
• gingival pocket is caused by gingival enlargement. Deeper structures aren’t involved, the tooth wall is enamel and all of them are suprabony

Question 15

Cross bite

Answer 15

When the posterior teeth are lingual or Buccal from the normal bite

Question 16

Edge to edge

Answer 16

When the max. And mand. Incisal surfaces occlude (touch)

Question 17

End to end

Answer 17

When the molars and premolars occlude cusp to cusp as viewed mesiodistally

Question 18

Open bite

Answer 18

When teeth that are supposed to contact each other don’t. They can’t be brought together

Question 19

Overjet

Answer 19

When the Maxillary teeth protrude. Measure distance with probe from lingual incisal surface of max. To labial surface of mand.

Question 20

Underjet (opposite of overjet)

Answer 20

Mandibular teeth protrude outward. Measure with probe from labioincisal of max. I linguoincisal surface of mand. Incisors

Question 21

Answer 21

Normal- incisal edge of max. Teeth are w/ incisal 3rd of mand. Teeth
Moderate- incisal edges of Max. Teeth are w/ middle 3rd of mand. Teeth

Question 25

Stages of perio lesions

Answer 25

1. Initial
2. Early
3. Established
4. Advanced

Question 26

Initial stage

Answer 26

Occurs within 2-4 days of irritation

• no clinical evidence of chance
• slight gingival redness w/ enlargement

Question 27

Early stage (stage 2)

Answer 27

Biofilm older and thicker (7-14 days)

Question 28

Established stage

Answer 28

Fluid and leukocytes migrate into tissue and the sulcus increases forming pocket

• inflammation/redness is obvious
• bleeding with probing
• spongy marginal gingiva

Question 29

Advanced stage

Answer 29

Bacteria from supragingival enter sulcus..leads to alveolar bone destruction
-CT fibers below JE are destroyed
