Abstract
The benefits of ionizing radiation are undeniable, but the increased use of these types of radiation results in a greater potential risk for patients and operators. The current study aimed to evaluate radiation doses in conservative and prosthodontics clinics. The study was carried out over a period of 15 months from January 2019 to April 2020. A cross-sectional analytic triangulated study design that includes quantitative and qualitative tools was used to collect data in conservative and prosthodontic clinics. Fifty- four participants (health providers) were participated in the current study; 40.7% were dentists, 40.7% medical radiographers and 18.6% nurses. All checked dental imaging devices have no tools for the purpose of quality control. The results revealed that participants recognized periapical, panorama, and cephalometric were recognized harmful as 30.8%, 40.4%, and 42.6% respectively. Around 66% of participants that have a good knowledge about radiation dose had read articles previously, and only 22.9% of poor knowledge participants had previously read such articles. A statistically significant difference (P-value= 0.044) was reported between the two groups. The current study showed the weakness of health providers in conservative and prosthodontic clinics in term of radiation dose safety and measures. The results of this study indicated that a big hidden risk on the dentistry clinics. This risk may effect on the health of patients and health providers as well. Therefore, a strong need to improve knowledge of health providers and increase safety measures regarding dental imaging.
