Abstract

Due to the great importance of radiation protection in dental services, in this work we aim to develop a thyroid shield from reusing lead foils contained in dental periapical radiographic films. To manufacture the thyroid shield, 300 lead foils contained in intraoral film packets were collected in dental offices in the city of Marabá, in Para State, Brazil, and reused for made the shield. It was observed that this shield made from recycled material is as effective in radiation shielding as those already on the market. The methodology presented here for the manufacture of thyroid shield is simple, effective, and inexpensive. This personal protective equipment constructed from recycled material is as effective as those already on the market, although it is still necessary to evaluate the new thyroid shield with more comprehensive testing
