Dennis' Ultimate Materials Quiz

Question 1

What is the function of primer solvents?

Question 2

While etching enamel, sahaij accidentally spills some saliva and blood on the enamel surface. What should he do?

Answer 2

Prolong the etch for 10 seconds than rinse

Question 3

Sahaij is preparing 2 small occlusal restorations on 2 teeth (one on each tooth). After he places a rubber dam on the patient, he drills an access hole on the first tooth, removes all soft/leathery dentine (leaving hard dentine), etches the enamel margins, applies primer, dries teeth, and then applies bond, followed with a 20 second blast of blue light. He then does the same process to the 2nd tooth. Afterwards he adds in composite resin, in increments (with curing) and completes the restorations (assume proper steps of finishing and polishing).

Did Sahaij make any mistakes? If so, explain how many mistakes he made. If there is a mistake, what is the greatest mistake?

Answer 3

minor- forgot to blow dry bond

major - 1st tooth had smear layer recreated due to incompletion of composite and drilling subsequently on the second tooth
