what is cervical burnout
Cervical burnout is an area of apparently increased radiolucency in the mesial and distal cervical (neck) regions of the tooth. Such regions are often mistaken for interproximal caries when in fact they only appear radiolucent because they have neither the radiopaque enamel of the region immediately above nor the bone tissue below.
What is superimposition
it appears to be when some sort of bone is in the background!
What is foreshortening?
Foreshortening exists if the vertical angulation is larger than necessary. The image of the teeth appears smaller than normal
What is elongation?
Elongation exists if the vertical angulation is less than is necessary. The image of the teeth appears larger than normal
What is parallel technique?
Used for mandibular
premolars and molars
• All other dentition – Bisecting
Angle Technique
What is the bisecting angle technique?
- Place film as close as possible to
tooth without bending film - Angle between the tooth’s long axis
and film is bisected - The primary x-ray beam is directed
perpendicular to the bisecting angle
