Objective: To evaluate the practice and knowledge of endodontic radiology as well as assess the knowledge of radiation biology, hazard, and protection among clinical dental students and interns. Materials and Methods: Cross-sectional study of clinical dental students and interns at University of Benin and University of Benin Teaching hospital respectively. Data was collected using a questionnaire which covered practice and knowledge of endodontic radiography, knowledge of radiation biology, hazard, and protection. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 17.0. Result: Seventy participants were included in the study, 40% were final year students and 24.3% house officers. Majority (95.7%) agreed that they exposed radiographs as part of endodontic treatment. Only 18.6% knew that the apices of teeth should be 3mm from the border of the X-ray film, while 24.3% knew that 3mm of periapical bone should be visible on X-ray. Less than half (31.4%) knew that paralleling technique was the technique of choice for endodontic radiography and this was statistically Significant in relationship to the status of the of the respondents. A few (4.3%) of the respondents had knowledge of new horizons in endodontic imaging. Half of the respondents knew that damage by X-rays is mainly due to formation of free radicals. The most frequently reported radiation hazards was reduced salivary flow, while the least reported was rampant caries. Most knew how to protect patients, themselves, and other persons while exposing radiographs. Conclusion: There is need for inclusion of endodontic radiography in the undergraduate curriculum to ensure proper and correct radiographs during endodontic procedure.
