TermDefinition
The bitewing view is used for detecting bone loss associated with periodontal disease. interproximal caries.
The dental assistant exposing a periapical film/sensor using the paralleling technique should always start with the anterior teeth.
Which film holder can aid in positioning the film during an endodontic procedure, because it fits around the dam clamp and the endodontic instruments? EndoRay
When using an x-ray sensor, it is important to always place the sensor parallel to the incisal or occlusal edge of the teeth.
Radiographic images on an edentulous patient might be required for detection of retained root tips, impacted teeth, and lesions.
A periapical view shows the tooth from the occlusal surface or incisal edge to about _____ mm beyond the apex to show the periapical bone. 2 to 3
Horizontal angulation is the side-to-side angulation.
An intraoral full-mouth survey on an adult consists of _____ images. 18 to 20
Basic principles of the bitewing technique include the film sensor is placed parallel to the crowns of the teeth.
The technique recommended by the American Academy of Oral and Maxillofacial and the American Association of Dental Schools because it provides the most accurate image with the least amount of radiation exposure to the patient is the _____ technique. paralleling
One technique for the management of the patient with a gag reflex is to use extraoral images.
Incorrect horizontal angulation of the PID results in overlapped contact areas.
Factors that can affect the quality of dental radiographs include film sensor placement. exposure. processing.
An anterior set of images includes canines and incisors.
When taking periapical images, it is best to start with anterior images because patients are less likely to gag with anterior film sensor placement. patients can tolerate the film sensor size easier.
The alignment of the x-ray beam in the horizontal and vertical planes formed by the long axis of the teeth and the film sensor placement is referred to as angulation.
The number of x-ray views that makes a patient’s full-mouth series depends on the dentist’s preference. the number of teeth present in a patient’s mouth. whether the paralleling or the bisecting technique is used.
In the paralleling technique, the central ray of the x-ray beam must be _____ to the film sensor and the long axis of the tooth. perpendicular
If the central ray of the x-ray beam is not centered on the film sensor, a partial image will result on the film sensor, which is called a(n) cone cut.
The major difference between the paralleling technique and the bisecting technique is film sensor position.
Occlusal radiographs can be used for locating retained roots of extracted teeth.
The bitewing view shows the crowns and interproximal areas of the maxillary and mandibular teeth.
If the patient is in a wheelchair, does not have the use of his or her upper limbs, and a film sensor holder cannot be used to stabilize the film sensor, you should ask the patient’s caregiver to assist in holding the film sensor.
When a size #2 film sensor is used, the anterior films are in the ______ position, and the posterior films/sensors are in the ______ position. vertical; horizontal
Insufficient vertical angulation can result in an image that is distorted.
