Tips and Tricks

  • Use the paralleling technique using a Rinnstyle positioning device set. These holder sets do the work for you and guarantee a good image every time.
  • Make sure the exposure settings are correct on the X-ray source (60–65 KVP suggested). You will need to adjust exposure times (pulses), depending on the X-ray source and the physical size of the patient. Remember that maxillary molar images need the most exposure time and mandibular anterior images need the least amount of time.
  • Place the sensor parallel to the teeth, but not necessarily up against the teeth.
  • Maxillary shots—place the sensor at the midline of the palate.
  • Mandibular shots—place the sensor more towards the tongue if necessary.
  • Use a long cone (16") technique for clearer images.
  • Make sure the bite block is fully in the patient’s mouth on molar shots.
  • If patient has trouble closing have them stabilize the arm of the holder with their finger.
  • Make sure the cone of the X-ray source is parallel to the arm of the holder and directed at the center of the aiming ring.
  • Use a cotton roll as a cushion between the sensor and torii.
  • For especially sensitive patients, there are foam cushions specifically made for use with sensors. Many of these work very well with sensitive patients and make placement much more comfortable.
