Abstract
An Orthopantomograph was provided with microswitches in order to reduce exposure time. The collimation was vertically reduced. The reduced field size obtained covered all dentoalveolar regions except the third molar areas. The dose of energy imparted was thus reduced from 1.6 to 0.6 mJ and thyroid gland dose from 0.13 to 0.04 mSv compared to complete pantomography. The economy in reduction of film size was 55%.Entities:
