A Brief Study about Principles of Panoramic Radiography (Orthopantography)

The proximal surfaces of the maxillary posterior teeth overlap and the temporomandibular joints are usually not completely depicted. On the other hand, using this approach, the apical regions of the roots and the nasopalatine space can be well observed. Guidance for technician for proper radiography different factors affecting the quality and anatomy on x-ray and different film artifact. It is concluded that Proper understanding of Radiography and positioning of patient and setting of proper technical factor and elimination of artefact will produce good quality OPG film making easy for interpretation.
