Why use a shielded PID?
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.
Available in two lengths:
The INTERMEDIATE PID (12" S.S.D.) is used where operatory space is limited and the LONG CONE technique is desired.
