CORRECT ANSWERS BUNDLED LEARNING

●● What are enamel rods composed of?
Answer: Calcium and phosphate molecules called hydroxyapatite
●● What is demineralization?
Answer: breakdown of the tooth structure with a loss of mineral content
●● What causes demineralization
Answer: Prolong period of low pH in the mouth which becomes an ideal
environment for bacteria to live and feed off fermental carbs. The
bacteria metabolize and make acid which harms the tooth structure.
●● What are the two primary bacteria that cause caries
Answer: S. Mutans and lactobacillus
●● What is remineralization?
Answer: Replacement of lost minerals in teeth
●● What elements helps with remineralization?
,Answer: Calcium, phosphate, and fluoride
●● Is calcium the best for remineralization of tooth?
Answer: No, fluoride is the best
●● What is fluorapatite?
Answer: the stabilized form of bone and tooth crystal that is insoluble in
water and resistant to decay
●● What is hydroxyapatite?
Answer: The calcium-rich crystalline structure of teeth and bones
●● Which one is better hydroxyapatite or Fluorapatite
Answer: Fluorapatite
●● What does calcium do to saliva
Answer: It buffers the pH in saliva
●● Does fluoride have to be present for for Fluorapatite?
Answer: Yes
●● What happens when demineralization exceeds the amount of
remineralization?
,Answer: Caries can occur
●● Can the tooth be repair itself if the surface is broken on the tooth
Answer: no, that why you should not press hard with the Shepard hook
explorer
●● What are incipient caries?
Answer: Demineralization or Decalifation the loss of calcium and
phosphate from the enamel. Beginning stage of caries, Affects only
enamel, Decalcifies and progresses, If progress is halted the tooth can
repair itself (remineralization)
●● What is a subsurface lesion
Answer: demineralized area below the surface of the enamel created by
acid that has passed through micropores between enamel rods; subject to
remineralization by action of fluoride
●● The tooth had a filling and now there's a cavity starting near the
filling? What kind is it? (Primary or secondary)
Answer: Secondary
●● Barely erupted molar has a cavity on the occlusal surface, is it
primary or secondary?
Answer: Primary
, ●● Where can caries mostly occur
Answer: On the pits and fissures of molars
●● What four different ways to identify caries?
Answer: Visual inspection
Tactile detection
Radiographic dectection
Emerging technologies
●● Are caries radiolucent or radioopaque?
Answer: Radiolucent
●● What is the percentage of all dental caries in the US?
Answer: 20%
●● From the 20%, what percentage are kids?
Answer: 80%. So from that 20% of people that have cavities, 80% of the
20% are children.
●● Which group of people are more prone to cavities?
Answer: Mexican Americans
