The criteria for imaging impacted teeth include identifying the impactions within the confines of the surrounding alveolar bone, then to determine their location relative to adjacent teeth and vital structures in the dento-alveolar complex and then finally to evaluate whether there is pathology.
The 8 inch=20 cm short cone technique exposes more tissue by producing divergent beam. The 16 inch=41 cm long cone technique reduce amount of exposed tissue by producing less divergent beam a sharper image. The intensity of the radiation is inversely proportional to the square of the distance.
Reverse town for fracture of condylar neck &ramus areas. Reverse Townes position, beam 30° up to horizontal. Used for condyles.

Because the salivary glands consist of soft tissue, they cannot be seen on radiographs unless special steps are taken to make them visible. In a technique called Sialography.
Digital imaging: This technique has been used extensively in general radiology, where it has great advantages over conventional methods in that there is a marked dose reduction and less concentrated contrast media may be used. The normal X-ray source is used but the receptor is a charged coupled device linked to a computer or a photo-stimulable phosphor plate which is scanned by a laser. The image is practically instantaneous and eliminates.
