Abstract Objectives: The aim of this study was to investigate the diagnostic accuracy of conventional bitewing, periapical radiographs, unfiltered and filtered digital panoramic images for the assessment of approximal carious lesions in posterior teeth. Radiographic Quality Evaluation: Posterior Bitewing Radiographs When taking a premolar bitewing image, the anterior edge of the film sensor should be placed __________. Correct If the patient doesnt completely bite their teeth together, the film does not get seated into the correct position, producing an image with a black (radiolucent) air space seen in the occlusal plane and incorrect proportions of the maxillary and mandibular crowns and alveolar crests. __________ are the most basic form of matter.

Vertical bitewings are often indicated in patients where current or past periodontitis is suspected so as to better reveal the relationships of the teeth to interproximal crestal bone levels. teeth are evident and the apical regions of mandibular teeth are seen. When taking a premolar bitewing image, the anterior edge of the film sensor should be placed. 22. Vertical bitewings Common recall film for periodontally involved patients. Con: Unable to see apex.

It is challenging to apply the work proposed for bitewing images directly to panoramic images because they are structurally different. When taking periapical x-rays, the patient's head is _____ for maxillary films and _____ for the mandibular arch. 1.
