All of these cells or tissue have fairly high radiation sensitivity, except __________. teeth are evident and the apical regions of mandibular teeth are seen. Incorrect Horizontal Angulation: positioning the central ray so that the horizontal angulation is not directed through the interproximal contacts of the adjacent teeth, provides an image that has overlap of adjacent structures in the horizontal plane (the contact areas of the teeth are superimposed over each other). Inadequate stabilization of the film/bite tab combination causes the film to tilt/tip producing an image that is not oriented correctly. When taking a premolar bitewing image, the anterior edge of the film sensor should be placed. Bitewing Surveys.

The x-ray was discovered in 1895 by __________. Incorrect settings may produce a film that has improper density (too light or dark) or poor contrast (too much or too little) making the interpretation of the image on the film difficult. Incorrect Vertical Angulation: positioning the central ray so that the vertical angulation is too flat (less than the optimal +10 degrees) provides an image that is elongated, or too long in the vertical dimension.

Vertical BitewingVertical bitewing films can be taken using tabs or abitewing instrument, just as with regular bitewings.The vertical angulation is +10 with tabs; the PID isaligned with the ring when using the instrument.The horizontal angulation is determined in the samemanner as it is with regular bitewings. The bitewing radiograph (BW) is an image that depicts the maxillary and mandibular crowns of the teeth, providing a clear image of the interproximal surfaces of the teeth and allowing for detection of interproximal caries. If you've accidentally put the card in the wrong box, just tap on the card to take it out of the box.
