Question 1

Condensing osteitis is an example of a lesion that can be described as:&#10;A) A focal opacity.&#10;B) A target lesion.&#10;C) A multifocal confluent.&#10;D) Ground glass.

Accepted Answer

Condensing osteitis is a localized area of increased bone density or opacity that appears in response to chronic low-grade inflammation. It is seen as a focal opacity on radiographs. It does not fit the descriptions of a target lesion, multifocal confluent, or ground glass appearance.

Question 2

Which of the following structures would appear the most radiopaque?&#10;A) Dental pulp&#10;B) Metallic restoration&#10;C) Periodontal ligament space&#10;D) Air space

Accepted Answer

Metallic restorations are the most radiopaque structures because they absorb more photons and hinder the passage of X-rays, which makes them appear white or lighter on a radiograph.

Question 3

The term ____ refers to a well-defined, localized radiopaque area surrounded by a uniform radiolucent halo.&#10;A) Focal opacity&#10;B) Target lesion&#10;C) Multifocal confluent&#10;D) Ground glass

Accepted Answer

The term "target lesion" is used to describe a radiographic finding that appears as a well-defined, localized radiopaque area surrounded by a uniform radiolucent halo. This appearance is likened to a bullseye or target. Option A, "Focal opacity," simply describes an area of radiopacity without further detail. Option C, "Multifocal confluent," describes multiple areas of radiopacity that are merging or overlapping with no mention of a halo. Option D, "Ground glass," describes a hazy or cloudy appearance of the lungs that does not fit the description of a target lesion.

Question 4

An x-ray is:&#10;A) An image that is produced on photosensitive film.&#10;B) A beam of energy that has the power to penetrate substances.&#10;C) A radiograph.&#10;D) The actual film exposed.

Accepted Answer

An x-ray is a beam of energy that has the power to penetrate substances. It is not the image produced on photosensitive film (A), nor is it the radiograph (C) or the actual film exposed (D).

Question 5

A unilocular lesion with corticated borders is usually indicative of a ____ process.&#10;A) Benign slow-growing&#10;B) Benign rapidly growing&#10;C) Malignant slow-growing&#10;D) Malignant rapidly growing

Accepted Answer

A unilocular lesion with corticated borders is typically seen in benign slow-growing processes such as a cyst or a benign tumor. Malignant processes often result in irregular or ill-defined borders. Rapidly growing processes are also less likely to have corticated borders. Therefore, option A is the best choice.

Question 6

Which of the following is an example of a radiopaque structure?&#10;A) Dental pulp&#10;B) Dentin&#10;C) Periodontal ligament space&#10;D) Soft tissue

Accepted Answer

Radiopaque structures are those that appear white or light gray on a radiograph, indicating that they absorb or block the passage of x-rays. Dentin is one example of a radiopaque structure in the oral cavity. Dental pulp and periodontal ligament space are radiolucent structures, appearing dark on a radiograph as they allow the passage of x-rays. Soft tissue can be either radiopaque or radiolucent, depending on its density and composition.

Question 7

Which of the following terms is used to classify a radiolucent lesion?&#10;A) Target lesion&#10;B) Multifocal confluent&#10;C) Ground glass&#10;D) Moth-eaten pattern

Accepted Answer

The "moth-eaten pattern" is a term used to describe a radiolucent lesion, often seen in aggressive bone lesions or infections.

Question 8

A(n) ____ is an image that is produced on photosensitive film.&#10;A) X-ray&#10;B) Radiograph&#10;C) Photon&#10;D) Electron

Accepted Answer

A radiograph, also known as an X-ray image, is produced on photosensitive film by exposing the film to X-rays that have passed through a body part. A radiograph can show the internal structures of the body, such as bones and organs, and is commonly used in medical imaging to diagnose and monitor conditions. Photon and electron are particles involved in the generation and detection of X-rays, but they are not the direct image produced on the film.

Question 9

A ground-glass appearance of bone is associated with which of the following diseases?&#10;A) Condensing osteitis&#10;B) Osteosarcoma&#10;C) Fibrous dysplasia&#10;D) Benign cementoblastoma

Accepted Answer

Fibrous dysplasia is characterized by a ground-glass appearance on radiographic images due to the replacement of normal bone with fibrous tissue and immature woven bone.

Question 10

Unilocular lesions tend to be:&#10;A) Small and expansile.&#10;B) Small and nonexpansile.&#10;C) Large and expansile.&#10;D) Large and nonexpansile.

Accepted Answer

Unilocular lesions are cysts that have only one chamber or compartment, which tends to be small and nonexpansile. This means that the cyst does not grow or stretch much beyond its initial size, and it usually contains fluid or semi-solid material.

Question 11

Radiopaque lesions may occur in:&#10;A) Bone but not soft tissue.&#10;B) Soft tissue but not bone.&#10;C) Neither bone nor soft tissue.&#10;D) Either bone or soft tissue.

Accepted Answer

The answer of Radiopaque lesions may occur in:&#10;A) Bone but...

Question 12

Which of the following is an example of a soft-tissue opacity?&#10;A) Osteitis deformans&#10;B) Sialolith&#10;C) Chondrosarcoma&#10;D) Florid osseous dysplasia

Accepted Answer

The answer of Which of the following is an example...

Question 13

A radiograph should not be referred to as a(n):&#10;A) Radiogram.&#10;B) Roentgenogram.&#10;C) X-ray.&#10;D) X-ray film.

The answer of A radiograph should not be referred to...

Question 14

The term ____ refers to a radiolucent lesion located around the crown of an impacted tooth.&#10;A) Periapical&#10;B) Inter-radicular&#10;C) Pericoronal&#10;D) Edentulous zone

The answer of The term ____ refers to a radiolucent...

Question 15

Most structures radiographed ____ exhibit uniform thickness and therefore appear ____.&#10;A) do; white&#10;B) do not; gray&#10;C) do; black&#10;D) do not; white

The answer of Most structures radiographed ____ exhibit uniform thickness...

Question 16

A radiograph appears ____ where the tissues are soft or thin.&#10;A) Radiopaque&#10;B) White&#10;C) Light&#10;D) Black or dark
