Question 10

• Prevents spontaneous polymerization when dispensed
• Slows polymerization from room light exposure

Answer 10

Butylated hydroxytoluene (BHT)

Question 11

• Many uses
• Splint, retainer, trauma stabilization
• Operative: Fiber reinforced composite restoration
• Claims to mitigate negative effects of C-factor

Answer 12

Biodentine

Question 13

• Bulk Fill, Fluoride releasing, Glass hybrid
• 8 shades available from supplier
• Available in UMKC clinic
• Does not require etching nor bonding
• Capsule- tap, push plunger, triturate (10 sec)
• Place in dispenser, click twice, dispense in prep

Answer 13

Equi forte

Question 14

• One tiny step beyond a sealant
• May even PRR small area (pit) and seal the remaining occlusal surface
• The carious lesion has STARTED but not progressed into dentin

Answer 14

PRR

Question 15

• Use etch to “chemically drill”
• ◦ 15% hydrochloric acid gel
• ◦ etch for 2 minutes
• ◦ up to three times
• Infiltrate with Icon® resin
• Indicated for Smooth surface lesions
• ◦ very good for small white spot lesions after ortho treatment

Answer 15

Resin infiltration
