Deck 20: Principles of Radiographic Interpretation

Question 1

If all the borders of a lesion are not seen,the dental professional should:

A)retake the bitewing.
B)retake the periapical.
C)recommend further imaging.
D)not take or recommend further radiographs.

Answer 1

recommend further imaging.

Question 2

Interpretation is an "explanation" of the structures seen radiographically.

Answer 2

True

Question 3

All of the following are questions that follow the preliminary radiographic examination EXCEPT one.Which one is the EXCEPTION?

A)What is the patient's chief complaint?
B)Is a bone or soft tissue pathology suspected?
C)Is the lesion radiolucent,radiopaque,or mixed?
D)Could the suspected "lesion" be an anatomic landmark?

Answer 3

What is the patient's chief complaint?

Question 4

When distinguishing between whether a radiographic finding is an anatomic landmark or a suspicious lesion,it is important to know the radiographic appearance radiopaque or radiolucency of the anatomic landmarks and their respective locations.

A)Both statements are true.
B)Both statements are false.
C)First statement is true,second is false.
D)First statement is false,second is true.

Question 5

Is a bone or soft tissue pathology suspected is a question that should be asked following the preliminary radiographic examination.

Question 6

Well-defined lesions are the signs of a malignant growth,whereas poorly defined borders suggest a benign lesion.

A)Both statements are true.
B)Both statements are false.
C)First statement is true,second is false.
D)First statement is false,second is true.

Question 7

Edentulous areas:

A)cannot be radiographed.
B)should be radiographed.
C)should not be radiographed.
D)may sometimes be radiographed.

Question 8

To produce adequate diagnostic films,the dental professional must:

A)know the patient's chief complaint.
B)know the identified differential diagnosis.
C)know if the lesion radiolucent,radiopaque,or mixed.
D)know what relevant information is being sought from the radiograph.

Question 9

If a lesion is not seen in three planes:

A)further imaging is needed.
B)no advanced imaging is needed.
C)the operator should dismiss the patient.
D)the operator should reschedule the patient's appointment.

Question 10

All of the following are steps that are to be taken in formulating a definitive diagnosis EXCEPT one.Which one is the EXCEPTION?

A)Diagnosis based on the interpretation
B)Identifying the patient's chief complaint
C)Interpretation of what has been identified
D)Identification of an area or structure that is questionable

Question 11

The dental professional is responsible for exposing and interpreting radiographs.The interpretation will ultimately lead to the formulation of a definitive diagnosis and treatment plan for the patient.

A)Both statements are true.
B)Both statements are false.
C)First statement is true,second is false.
D)First statement is false,second is true.

Question 12

In determining a differential diagnosis,identify the radiographs that should be initially considered:

A)MRI.
B)CT scan.
C)full mouth series.
D)panoramic radiograph.

Question 13

Rapidly growing lesions without distinct borders are usually:

A)cysts.
B)benign.
C)malignant.
D)not cause for concern.

Question 14

The interpretation of radiographs provides the signs or symptoms on which to build a diagnosis.

Question 15

Anatomic landmarks are located in specific areas of the oral cavity and are well within normal limits on radiographs.

Question 16

The question,have periapical and bitewing radiographs been taken recently is a preliminary question a diagnostician should ask,and the question,what were the clinical findings that prompted the dental professional to request the radiographs is a question that follows the preliminary question.

A)Both statements are true.
B)Both statements are false.
C)First statement is true,second is false.
D)First statement is false,second is true.

Question 17

In addition to radiographic findings,all of the following EXCEPT one may be part of a dental diagnosis.Which one is the EXCEPTION?

A)Vitality testing
B)Medical history
C)Blood pressure
D)Clinical examination

Question 18

The final diagnostic role rests with the dentist.

Question 19

Cysts and benign lesions usually grow:

A)slowly.
B)rapidly.
C)at various rates.
D)at no specific rate.
