MULTIPLE CHOICE
1. The Primary Purpose Of Dental Radiographs Is To:
A. Replace Clinical Examination Entirely.
B. Detect Dental Conditions That Cannot Be Seen Clinically.
C. Increase The Cost Of Dental Care.
D. Serve As A Backup For Clinical Records.
ANSWER: B
The Primary Purpose Of Dental Radiographs Is To Detect Dental Conditions That Cannot
Be Observed Through Clinical Examination Alone, Such As Cavities, Bone Loss, And
Abscesses. Radiographs Provide Essential Information For Accurate Diagnosis And
Treatment Planning.
A: Radiographs Do Not Replace The Clinical Examination; They Complement It By
Revealing Conditions That Are Not Visible To The Naked Eye.
C: While Radiographs Do Incur A Cost, Their Main Role Is Diagnostic, Not To Increase
Healthcare Expenses.
D: Although Radiographs Can Serve As A Backup, Their Primary Function Is
Diagnostic, Not Archival.

,2. The X-Ray Was Discovered In Which Year?
A. 1888
B. 1895
C. 1902
D. 1920
ANSWER: B
Wilhelm Roentgen Discovered X-Rays In 1895, Which Revolutionized Medical And
Dental Imaging. This Discovery Earned Him The First Nobel Prize In Physics In 1901.
A: 1888 Is Not The Correct Year; Roentgen's Discovery Was A Breakthrough That
Occurred Later.
C & D: These Dates Fall After The 1895 Discovery, Marking Developments In The
Field But Not The Original Discovery.

3. Who Took The First Dental Radiograph On A Living Person?
A. Weston Price
B. Wilhelm Roentgen
C. Edmund Kells
D. Otto Walkoff
ANSWER: C
Edmund Kells Was The First To Take Dental Radiographs On A Living Person. His
Work Laid The Foundation For Dental Radiography In Clinical Practice.
A: Weston Price Was A Well-Known Figure In Dental Research, But He Was Not The
First To Take Dental Radiographs.
,B: Roentgen Discovered X-Rays But Did Not Apply Them To Dentistry On Live
Patients.
D: Otto Walkoff Was An Early Pioneer In Dental Radiography But Did Not Take The
First Radiographs On Living Persons.

4. Which Of The Following Improvements Has Greatly Reduced Radiation Exposure To
Patients Since The 1920s?
A. Use Of Higher Voltage In X-Ray Machines
B. Digital Imaging Systems
C. The Development Of Faster Film
D. Introduction Of Lead Aprons
ANSWER: C
The Development Of Faster Film Significantly Reduced The Radiation Needed For
Dental Imaging. Faster Films Require Less Exposure To X-Rays While Still Providing
High-Quality Images.
A: Higher Voltage Can Improve Image Quality But Does Not Directly Reduce Radiation
Exposure In The Same Way Faster Film Does.
B: Digital Imaging Does Reduce Exposure But Did Not Play A Major Role Until The
Late 20th Century.
D: Lead Aprons Are Protective But Do Not Directly Reduce The Radiation Dose Needed
To Capture An Image.

A. F. Gordon Fitzgerald
B. Franklin Mccormack
C. Howard R. Raper
D. Wilhelm Roentgen
ANSWER: A
F. Gordon Fitzgerald Introduced The Long-Cone Technique, Which Improved The
Quality And Accuracy Of Dental Radiographs By Reducing Image Distortion And
Increasing Detail.
B & C: Franklin Mccormack And Howard R. Raper Made Contributions To Dental
Radiography, But They Did Not Introduce The Long-Cone Technique.
D: Wilhelm Roentgen Discovered X-Rays But Did Not Develop Specific Techniques For
Dental Radiography.

6. Which Of The Following Is A Key Advantage Of Digital Radiography Over
Traditional Film-Based Radiography?
A. Increased Chemical Usage
B. Faster Image Retrieval
C. Higher Radiation Dose
D. The Need For A Darkroom
ANSWER: B
Digital Radiography Allows For Instant Image Retrieval, Eliminating The Need For Film
Development And Enhancing Diagnostic Efficiency.
A: Digital Imaging Reduces The Need For Chemicals Used In Film Processing.
