Background: In dentistry, radiographs are very helpful in detecting oral diseases, cavities, bone related problems, treatment planning as well as follow-up treatments. However, it should be clinically justified to obtain maximum benefit and reduce further effects. This study was conducted to assess the knowledge, awareness and practice of general dental practitioners towards oral radiology and protective guidelines. Materials and Methods: A descriptive cross – sectional study carried out among 198 general dental practitioners working within Khartoum locality during period from January 2016 – April 2016. Data was collected via self administered questionnaires composed of demographic data and closed ended questions regarding their knowledge, awareness and practice towards the hazardous effects of dental x-ray and radiographic protection guidelines. Comparison between variables was assessed by Chi square test with the level of significance set at P ≤0.05. Results: The overall correct response among the study population was ranged 26.3% 74.3%. more than half (55.1%) were aware that dental x-rays are harmful, 40.9% know that x-ray beams cannot be reflected from room walls, 48.5% perceived that x-rays do cause ionization to matter, while 46% had the knowledge of deterministic and stochastic effects and the majority 74.3% recognized that dental radiography is not an absolute contraindication in pregnant women. Significant correlation between the number of years in practice and level of knowledge and practicing protective measure regarding radiation exposure (P˂0.05), but no difference were found between male and female dentists (P˂0.05). Conclusion: The results indicated insufficient knowledge and awareness regarding x-ray exposure, and practice of protective measures. This outcome necessitates continual education by way of dental radiology courses to ensure maximum safety for both dentist and patient.
