Exam 13: The Periapical Examinationparalleling Technique

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.

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

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

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

Have film holders always been used in dental radiography?

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

The bitewing survey may consist of two to eight radiographs.

Each of the following statements regarding the fundamentals of periapical radiographs is correct EXCEPT one. Which one is the EXCEPTION?

What is the spot on the surface of the patient's face toward which the central ray is directed called?

Conditions that would indicate the need for a periapical radiograph include each of the following EXCEPT one. Which one is the EXEPTION?

What device is used to facilitate positioning the image receptor, film or digital sensor parallel to the teeth?

The paralleling technique is also called the:

Where should the open end of the PID be placed relative to the patient for radiographic exposures?

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

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

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

Which of the following statements is correct?

Each of the following statements regarding the point of entry is correct EXCEPT one. Which one is the EXCEPTION?

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

The open end of the PID should almost touch the face with its midpoint centered over the point of entry before exposure.
