BACKGROUND AND AIM: Protective equipment, such as lead aprons and thyroid shields, is effective in reducing patient radiation. This study was conducted for evaluation the use of thyroid shields and lead aprons in dental offices, in Kerman, Iran, in June 2014.METHODS: In this descriptive-analytical study, 106 dental offices with active X-ray machines were evaluated in Kerman. The information was recorded on a data sheet consisting of eight questions in three fields of the rate of the use of lead aprons, thyroid shields and taking part in radiation protection courses. Data were evaluated using frequency distribution and chi-squared test.RESULTS: In this study, 12.3% of clinics were equipped with lead aprons but only 5.7% used them for all the patients. Only 10.4% of Kerman Dental Clinics had thyroid shields. Approximately, 9.7% of Kerman dentists had participated in continuous retraining courses on radiation protection. There was a significant relationship between clinics equipped with lead aprons with more job experience.CONCLUSION: The results showed that the rate of the use of lead aprons and thyroid shields in dental clinics equipped with X-ray machines in Kerman is not sufficient and is far from the international standards. Therefore, it is suggested that radiation protection equipment be promoted and oral and dental radiologists be responsible for the use of such equipment in their clinics.
