Abstract
This study evaluated the radiation dose reduction, operator acceptance, and patient
acceptance of two types of leaded thyroid shields designed for use during intraoral
dental radiography. Exposure levels were measured with thermoluminescent dosimeters
on three groups of 20 patients undergoing complete mouth (20-film) surveys. Skin entrance
dose to the thyroid was 20 mR per complete mouth survey without a shield in place,
12 mR per complete mouth survey with the experimental shield in place, and 9 mR with
the commercial shield. Patients and radiologic technologist were surveyed to determine
patient comfort and operator acceptability. Patient and operator acceptability were
higher for the experimental shield than for the commercial shield.
