lecture 12: dental disease

Question 1

human teeth have how many phases?

Answer 1

2

Question 2

what are the two phases?

Answer 2

primary teeth and permanent teeth

Question 3

human dental formula

Answer 3

2:1:0:2/2:1:0:2 (primary) 2:1:2:3/2:1:2:3

Question 4

what are caries

Answer 4

• name of disease process not a lesion
• localized demineralization of teeth through acidic affects of sugar
• result in chronic destruction of enamel, dentin, cementum and pulpae
• complications include inflammation/infection and tooth loss

Question 5

What are Alveolar cavities of pulpal origin?

Answer 5

progression of acute pulpitis and is initiated by invasion of oral bacteria into pulp cavity of tooth

Question 6

ACPO complications

Answer 6

-antemortem tooth loss
-infection
-inflammation
death via septicemia (rare)

Question 7

what is periodontal disease?

Answer 7

• chronic and destructive inflammation of periodontal tissue (periodontal ligament, alveolar bone and cementum)
• causes alveolar resorption
• preceded by gingivitis

Question 8

periodontal disease is commonly caused by what?

Answer 8

• dental (bacterial) plaque

- facilitated by poor diet, hygene, severe dental attrition

Question 9

AMTL (antemortem tooth loss)

Answer 9

-secondary to ACPO, Periodontitis, trauma, caries, dental attrition

Question 10

Dental calculus

Answer 10

-buildup of plaque and tartar on gums and teeth

Question 11

Dental attrition

Answer 11

• wear on contact surfaces of teeth
• reflects masticatory load and dietary consumption
• gives relative age at death
• influences progression of other dental diseases

Question 12

enamel hypoplasia

Answer 12

• enamel deficiency reflecting nonspecific physiological stress during dental development
• usually shows linear grooves on teeth
