When converting the maximum permissible dose (MPD) of 0.1 rem/year for non-occupationally exposed personnel, the System Internationale equivalent is __________. The intraoral film that is used for producing BWs has the highest spatial resolution which is crucial for the detection of the subtle changes that occur in dental diseases. ask the patient's caregiver to assist in holding the film sensor. Because the entire x-ray area is considered a radiation hazard area, a radiation hazard sign must be posted in __________. The maxillary sinuses are located above the central incisors. Fixer cutoff will result in a straight, __________ border. chart and be of diagnostic quality. All More damage occurs when tissues When taking radiographs using film, the white side of the film is always placed, For the patient with a hypersensitive gag reflex, the teeth that should be exposed last are, Factors that can affect the quality of dental radiographs include. A lead apron and a thyroid collar __________. Why the ALARA concept?? At least -The crestal bone, The alignment of the x-ray beam in the horizontal and vertical planes formed by the long axis of the teeth and the film sensor placement is referred to as. or mandibular MOLAR exposure-, Anterior locating retained roots of extracted teeth. The most commonly used film size for adult intraoral dentistry is size __________. The penetrating power of the x-ray beam is controlled by the settings on the __________. Posterior bitewing the film is positioned so that the distal aspect of the last erupted crown is visible on the film. For molar bitewings, place the film/sensor at the middle of the mandibular second premolar (1). Dose rate=dose/time (rate at which dose is given)- rate at By moving a circular mask over the image, the area of jaw separation was determined. embossed dot next to the occlusal/incisal edge (helps with mounting), Correct centering of position indicating The portion of the x-ray machine that produces x-rays is the __________. Two of the most common positioning errors are; Not positioning the film anteriorly enough in the arch, so that the BW doesnt provide an adequate view of the distal aspect of the cuspids. processing. The bisecting-angle instrument (BAI) uses _____ to determine the correct PID angulation. Incorrect positioning of the film in relation to the teeth produces a BW image that doesnt provide a clear view of some areas of the teeth that are required. 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.
