What are bitewing radiographs primarily used for?
Bitewing radiographs are indicated primarily to detect or monitor interproximal caries if the proximal surfaces of the teeth cannot be visually or tactilely examined.
In which position should the patient be placed for bitewing radiograph?
Seat the patient, in an upright position in the dental chair. Place the lead apron and thyroid collar on appropriately. Ensure that the patient’s head is stabilized against the headrest and that their occlusal plane is parallel to the floor, in the closed position. Preparing the film/sensor.
Which of the following would a patient be allowed to wear when having a panoramic radiograph taken?
A panoramic x-ray examination requires no special preparation. You may be asked to wear a lead apron as a safety precaution to protect the rest of your body from any radiation exposure that may scatter from the panoramic x-ray beam.
Which teeth should be imaged on a horizontal premolar bitewing?
Regardless of the devices or receptors used, when exposing bitewing radiographs, it is important to focus on five performance criteria: The maxillary and mandibular arches should be imaged equally. The premolar image should display the distal surfaces of the maxillary and mandibular canines.
What vertical angulation should be used for bitewing?
what is the purpose of bitewing images? what horizontal angulation should be used for bitewing images? Vertical angulation of +10 degrees is used to compensate for the slight bend of the upper portion of the film and the tilt of the maxillary teeth.
How often should Bitewings be taken?
Normally four bitewings are taken as a set. They may be taken as often as every six months for people with frequent cavities or every two or three years for individuals with good oral hygiene and no cavities.
Which is associated with incorrect vertical angulation?
Correct vertical angulation results in a radiographic image that is the same length as the tooth. Incorrect vertical angulation results in an image that is not the same length as the tooth being radiographed.
What is vertical angulation?
Vertical angulation: Direct the central ray of the x-ray beam perpendicular to the film and the long axis of the tooth. Horizontal angulation: Direct the central ray of the x-ray beam through the contact areas between the teeth.
What vertical angulation is used to take a bitewing radiograph?
The aim of this study was to assess the effect of x-ray beam vertical angulation on radiographic assessment of alveolar crest level in five human mandibles. A standardized technique was used to take bitewing radiographs with -10 degrees, 0 degree and +10 degrees angulation of X-Ray beam.
