Dental Radiology Review Quiz
Welcome to the Happy Times Radiology Review Quiz!
Questions are RANDOM and cover a whole lot of material. . . Stuff you maybe haven't learned yet either? It's meant to be a nice study guide and as a quick learning tool to help some of these things stick a lot better. Radiology is all about memorization, so the more things pop up, the more likely you are to remember them and identify them on spot tests and exams.
SPELLING IS IMPORTANT! Dr. Packota will take marks off for incorrect spellings!
The test depends on proper spelling and proper phrases i. E."floor Read moreof nasal sinus" all needs to be written out to get the answer correct.

WHAT IS THE MOST LIKELY CAUSE FOR THE ANOMALY AT THE WHITE ARROW?
Explanation
The most likely cause for the anomaly at the white arrow is a combination of an overhanging restoration, a defective restoration, and the restoration itself. An overhanging restoration occurs when the dental material extends beyond the intended boundaries, causing an abnormality. A defective restoration refers to a restoration that is flawed or faulty in some way, such as improper fit or material failure. Therefore, it is likely that the anomaly at the white arrow is a result of these issues with the restoration.Rate this question:
- 32.
IDENTIFY THE ANOMALY
Explanation
A supernumerary tooth, specifically a mesiodens, refers to the presence of an extra tooth in the dental arch. This condition is considered an anomaly because it deviates from the normal dentition pattern, which typically includes 32 permanent teeth. A supernumerary tooth can cause various dental problems such as crowding, misalignment, or impaction of other teeth. Treatment may involve extraction or orthodontic intervention to ensure proper alignment and function of the teeth.Rate this question:
- 33.
IDENTIFY THE ANOMALY
Explanation
A supernumerary tooth is an extra tooth that develops in addition to the normal set of teeth. A mesiodens is a specific type of supernumerary tooth that grows in the middle of the upper jaw, between the two front teeth. This condition is considered an anomaly because it is not typical to have an extra tooth in this location. Therefore, the presence of a supernumerary tooth, specifically a mesiodens, is the anomaly in this case.Rate this question:
- 34.
IDENTIFY THE ANOMALY
Explanation
A supernumerary tooth, specifically a mesiodens, is an anomaly in dental development where an extra tooth forms in the middle of the upper jaw. This condition is considered abnormal as it deviates from the usual pattern of tooth development. The presence of a supernumerary tooth can cause various dental issues such as crowding, misalignment, and impaction of other teeth. Therefore, identifying a supernumerary tooth, especially a mesiodens, is crucial for proper dental treatment and management.Rate this question:
- 35.
IDENTIFY THE ANOMALY
Explanation
The correct answer is "macrodontia, macrodont." The anomaly in this case is that both terms "macrodontia" and "macrodont" refer to the same condition, which is the abnormal enlargement of teeth. The suffix "-ia" is commonly used in medical terminology to indicate a condition or state, while the term "macrodont" itself already implies the abnormality of enlarged teeth. Therefore, the use of both terms is redundant and unnecessary.Rate this question:
- 36.
IDENTIFY THE ANOMALY
Explanation
The anomaly in this case is the repetition of the word "microdont" in the list. It is redundant and unnecessary to include both "microdontia" and "microdont" as they essentially mean the same thing. Therefore, the correct answer is to identify this repetition as the anomaly.Rate this question:

IDENTIFY THE ANOMALY
Explanation
Gemination refers to the phenomenon of a consonant being pronounced as a double or long sound. It occurs when a single consonant is repeated in a word, resulting in a longer duration of the sound. This can be observed in various languages, such as Italian, where gemination is common. For example, in the word "pizza," the "z" sound is geminated. This anomaly stands out because it deviates from the typical pronunciation of a consonant and can affect the meaning or interpretation of a word.Rate this question:
- 40.
IDENTIFY THE ANOMALY
Explanation
The anomaly in this question is that all three terms - taurodont, taurodontism, and taurodontia - are variations of the same word. They all refer to a dental condition characterized by elongated pulp chambers in the molars, resulting in a rectangular shape instead of the usual hourglass shape. The terms taurodont, taurodontism, and taurodontia are used interchangeably to describe this anomaly in dental anatomy.Rate this question:

IDENTIFY THE ANOMALY
Explanation
The correct answer is "dens in dente, dens invaginatus." These are both dental anomalies that involve the abnormal development of teeth. Dens in dente, also known as dens invaginatus, is a condition where the outer surface of a tooth invaginates or folds into the interior of the tooth. This can lead to the formation of a deep pit or groove on the tooth's surface, which can be prone to decay and other dental problems. Therefore, both dens in dente and dens invaginatus refer to the same dental anomaly.Rate this question:

- G.
Underexposed (mA, kVp or exposure time too low)
- H.
Overexposed (mA, kVp or exposure time too high)
- I.
Depleted/diluted/contaminated developer solution
Correct Answer(s)
B. Overdeveloped (temp too high or time too long)
D. Inadequate fixation
E. Accidental exposure to light
H. Overexposed (mA, kVp or exposure time too high)Explanation
Radiographs that are too dark can be caused by several factors. One possible cause is overdevelopment, which occurs when the temperature of the developer solution is too high or when the film is left in the developer for too long. Another cause could be inadequate fixation, where the film is not properly rinsed after development, leading to excessive darkness. Accidental exposure to light can also result in dark radiographs, as the light can affect the film's sensitivity. Additionally, overexposure, caused by using high mA, kVp, or exposure time settings, can lead to excessive darkness.Rate this question:

Correct Answer(s)
A. Underdeveloped (temp too low or time too short)
C. Excessive fixation
G. Underexposed (mA, kVp or exposure time too low)
I. Depleted/diluted/contaminated developer solutionExplanation
Radiographs that are too light can be caused by underdeveloped films, which can occur if the temperature of the developer solution is too low or if the development time is too short. Excessive fixation can also cause the radiographs to appear too light. Additionally, if the exposure settings are too low (mA, kVp, or exposure time), the resulting images may be underexposed and appear too light. Lastly, depleted, diluted, or contaminated developer solution can also lead to radiographs that are too light.Rate this question:
