Margraf Dental’s Shielded PID’s

ROUND POSITION INDICATING DEVICE (OPEN END LEAD-LINED CONE)



Why use a shielded PID?

Because…

  • A shielded PID will reduce secondary or scatter radiation. Secondary radiation must be considered when taking X-rays. The scattered radiation will create a loss of contrast and definition. Secondary radiation comes from radiation exiting the side of the PID, bouncing off other hard tissue, and back to the film. This scatter radiation will reduce the diagnostic quality of an x-ray.
  • Federal and most State laws require a shielded PID. For maximum protection from x-radiation exposure, Margraf Dental PIDs (open end lead-lined cone) are designed to exceed all federal and state requirements.
  • A shielded PID reduces the area of the patient's tissue that is exposed to radiation.
  • Margraf Dental PIDs (open end lead-lined cones) are available for nearly all makes and models of dental x-ray units whether new or old.

Available in three lengths:

  • The SHORT PID (8" Source-to-Skin Distance) is for the bisecting angle technique, or the standard practice of the profession
  • The INTERMEDIATE PID (12" S.S.D.) is used where operatory space is limited and the LONG CONE technique is desired.
  • The LONG PID (16" S.S.D.) is for the Long Cone Paralleling technique, or where undistorted x-rays are desired.

Measurements and What They Mean

AFD = Anode to Film Distance
SSD = Source (Anode) to Skin Distance FFD = Focal to Film Distance

Short, Intermediate and Long designation is based on the combination of PID length, and the distance from the source to the opening of each individual machine.

FFD or AFD Inches / [mm]
