✔✔A patient presents for a bridge preparation. The dentist administers the local
anaesthetic them the DA takes an impression of the lower left quad. Teeth 36 and 37
are missing and tooth 38 has drifted into 37's position. The bridge will go from 35 to
tooth 38. The insurance plan provides 80% reimbursement for this treatment.
1. What direction has tooth 38 drifted into?
2. What type of provisional restoration would be best for this patient?
3. What will the alginate impression be used for?
4. How many units will the patients bridge consist of? - ✔✔1) Mesially
2) Custom acrylic
3) As a matrix for the provisional
4) 3
✔✔A patient presents for an emergency exam of tooth 16. The tooth has been sensitive
to pressure for several weeks and the patient indicates that it's getting worse. The
dentist does an intra-oral exam and prescribes a direct digital periapical radiograph of
the area. The DA is directed to assemble equipment and supplies for pulp vital testing.
1. Where would the dental assistant place the sensor for the prescribed image?
2. What radiolucent structure would the dental assistant expect to see near the apex of
the fractured tooth
3. Which one of the following teeth would be best as the control tooth for the pulp vitality
test?
4. The cold test for the tooth causes an intense pain that does not resolve for a few
minutes. What diagnosis is most probable? - ✔✔1) Away from the tooth, near the vault
of the palate
2) Maxillary sinus
3) 26
4) Irreversible pulpitits

of the dam when placed? - ✔✔The arch is punched too flat

completed dam? - ✔✔The arch is punched too curved

leakage throughout? - ✔✔The holes are punched too large

exposed teeth? - ✔✔The holes are punched too far apart
