100% CORRECT ANSWERS
5. In addition to the panoramic image, which intraoral radiographs would be
most beneficial for the total care of this patient?

b. Four horizontal bite-wing radiographs
c. Four vertical bite-wing radiographs
d. A full-mouth series
Use Fig. 6-35 to answer questions 6 and 7.
. D. Because of the caries, periodontal disease, missing teeth, and numerous restorations, a full-
mouth series would be required to completely evaluate this patient.
A. Occlusal radiographs would not give enough information regarding this patient's
dental condition.
B and C. Bite-wing radiographs would not give enough information regarding this
patient's dental condition.
6. All the anatomical landmarks may be viewed on this radiograph EXCEPT
a. incisive foramen.
b. median palatal suture.
c. maxillary torus.
d. inferior nasal conchae.
,C. The maxillary torus is not visible on this periapical image.
A. The radiolucent incisive foramen is visible between the roots of teeth #8 and #9.
B. The median palatal suture is the vertical radiolucent line between the roots of teeth #8 and
#9. D. The inferior nasal conchae are the diffuse radiopacities seen within the nasal cavity
7. The yellow arrow is pointing to a V-shaped radiopacity. What is this
radiographic finding?
a. Anterior nasal spine
b. Nasal septum
c. Nutrient canal
d. Root fracture
A. The anterior nasal spine is a V-shaped radiopacity visible on maxillary anterior
periapical images.
B. The nasal septum is a vertical radiopaque division of the nasal cavity.
C. Nutrient canals are not visible in this area of the maxilla.
D. A root fracture is not present but would appear as a radiolucent line.
Use Fig. 6-36 to answer questions 8 to 10.
8. Which tooth has been extracted and is not visible on this periapical image?
a. #4
b. #5
c. #12
d. #13
C. Tooth #12 has been extracted.

The lesion has penetrated the enamel and entered the dentin.
A. No caries activity is present on the distal of maxillary premolar.
C. No caries activity is present on the distal of maxillary first molar.
D. No caries activity is present on the mesial of maxillary second molar.
10. Which restorative material is present on the maxillary first molar?
a. Amalgam
b. Amalgam with base material
c. Gold
d. Composite
A. An amalgam restoration is seen on the occlusal surface of the maxillary first molar.
B. A. No base material is visible radiographically.
C. Gold is equally radiopaque as amalgam but demonstrates smooth borders.
D. Composite is not typically as radiopaque as this image demonstrates.
