bisecting angle periapical
what are the reasons for utilising a bisected angle technique
- to separate the roots of teeth
- to overcome superimposition
- when assessing root fractures
- when localising unerupted teeth
- when its ok to have a distorted view
what technique would be used in response to wanting a bigger view compared to the bisected angle
oblique occlusal radiograph
what technique would have had to been used to produce this radiograph

oblique occlussal radiograph
what radiograph technique is being used here

oblique occlusal radiograph
which radiograpgh technique allows you to see the teeth from crown to apex
oblique occlusal
when would you request a oblique occlusal radiograph
- when a larger area is to be imaged than will fit on periapical film
- some patients who retch
- children who cannot tolerate periapical views
- parallax views - to help assess the relative position of pathology or uerupted teeth
this view is used to help assess the relative position of pathology or unerupted teeth - what is the name of this view

mandibular occlusal views
mandibular true occlusals are often taken to check for what?

often taken to check for submandibular duct calculi
what is a parallax view
2 radiographs taken of same object with a change in angulation of beam
