Question 1

The purpose of the periapical examination is to record the crowns and alveolar bone crests of the teeth in both arches on one radiograph.

Accepted Answer

The purpose of the periapical examination is to record the apex and surrounding bone of one or two teeth in a specific region on one radiograph. It does not aim to record the crowns and alveolar bone crests of all teeth in both arches.

Question 2

Which of the two techniques for obtaining intraoral radiographs is considered the technique of choice?

Accepted Answer

Periapical radiography is considered the technique of choice for obtaining intraoral radiographs.

Question 3

The word "periapical" is derived from the Greek word peri (meaning around) and the Latin word apex (meaning highest point).

Accepted Answer

The answer of The word "periapical" is derived from the...

Question 4

Periapical radiographs can image only one tooth on each radiograph.

Accepted Answer

Periapical radiographs are designed to image one tooth and its surrounding structures on each radiograph. This type of radiograph provides a detailed image of the tooth root and surrounding bone structure, making it an important tool for diagnosing dental issues such as decay, infections, and bone loss.

Question 5

The bitewing technique could be considered a modification of the bisecting technique used for exposing periapical radiographs.

Accepted Answer

The bitewing technique is indeed a modification of the bisecting technique, but it is used specifically for capturing interproximal images. The bisecting technique is used for periapical radiographs.

Question 6

The technique used to image <KT>bitewing radiographs is unique to the bitewing exam.

Accepted Answer

The technique used to image bitewing radiographs is also used for periapical and panoramic radiographs.

Question 7

The size #3 film or phosphor plate is used exclusively for occlusal radiographs of adult patients, and the size #4 film or phosphor plate is used exclusively for horizontal bitewing radiographs of adult patients.

Accepted Answer

The given statement is correct. Size #3 film or phosphor plate is used exclusively for occlusal radiographs of adult patients, and size #4 film or phosphor plate is used exclusively for horizontal bitewing radiographs of adult patients.

Question 8

The periapical examination is sometimes referred to as an <BOLD>interproximal radiograph.

Accepted Answer

The answer of The periapical examination is sometimes referred to...

Question 9

While the use of a size #2 image receptor for anterior periapical radiographs is acceptable, the narrower size #1 image receptor may fit this area better.

Accepted Answer

While a size #2 image receptor is often used for anterior periapical radiographs, using a size #1 image receptor may provide a better fit for this smaller area.

Question 10

An image receptor holding device should be used to position intraoral radiographs.

Accepted Answer

The answer of An image receptor holding device should be...

Question 11

Periapical image receptors for exposure of anterior areas are placed with the long dimension vertically.

Accepted Answer

The answer of Periapical image receptors for exposure of anterior...

Question 12

Neither the paralleling nor the bisecting technique completely meets all five requirements for accurate shadow casting in all regions of the oral cavity on all patient types.

Accepted Answer

Both paralleling and bisecting techniques have advantages and disadvantages, and neither technique completely meets all five requirements for accurate shadow casting in all regions of the oral cavity on all patient types.

Question 13

The correct horizontal and vertical angulations are critical to producing quality periapical radiographs.

Accepted Answer

The answer of The correct horizontal and vertical angulations are...

Question 14

The bisecting technique originated from the rule of isometry.

Accepted Answer

The bisecting technique did not originate from the rule of isometry, but instead was developed as a way to simplify complex geometric constructions.

Question 15

The bitewing survey may consist of two to eight radiographs.

Accepted Answer

The answer of The bitewing survey may consist of two...

Question 16

Periapical image receptors for exposure of posterior areas are placed with the long dimension vertically.

Accepted Answer

Periapical image receptors for exposure of posterior areas are usually placed with the long dimension vertically to properly capture the entire tooth and surrounding structures. This allows for more accurate diagnosis and treatment planning.

Question 17

Placing the dot in the slot of the film holder positions the identification dot toward the apices of teeth.

Accepted Answer

Placing the dot in the slot of the film holder positions the identification dot toward the incisal or occlusal surface of the tooth, not toward the apices.

Question 18

Have film holders always been used in dental radiography?

Accepted Answer

The answer of Have film holders always been used in...

Question 19

The identification dot should be placed toward the apices of the teeth when exposing periapical radiographs.

Accepted Answer

The identification dot should be placed toward the apices of the teeth when exposing periapical radiographs to ensure that the resulting image accurately represents the spatial relationship of the teeth and surrounding structures. Placing the dot in the wrong position can lead to incorrect interpretations of the radiograph.

Question 20

All vertical angle deviations from zero in which the tip of the PID is tilted toward the floor are called "negative angulations."

Accepted Answer

This statement is stating that any angle deviation in which the PID tip is tilted towards the floor is considered a negative angulation. As such, the statement is true.
