Clinical Education has been designed to make graduates who have competency in the medical science and dentistry science along with the skill in the dentistry. Dental Radiology is one of the achievement that has to be obtained. Professional Student need to obtain competency in dental radiology, to minimize the errors and mistakes. To deter- mine the diagnosis it is required to have good result of radiograph for its correctness and accuracy. However, errors and poor quality of radiographs are still frequently occurred. Technical error made by operator will lead to redoing the radiograph, which significantly increased radiation exposure to the patient this definitely breached the principle of ALARA (As Low As Reasonably Achievable). Academic institution is having crucial role to educate students the awareness to avoid radiographic error. Hence, evaluation in dental clinical education need to be done; to monitor the performance of the system, and the modification plan in accordance to any technical requirement. The type of re- search using Study Literature Review (SLR). SLR method is used to identify, study, evaluate, and interpret all literature findings systematically, which in each process follows the established steps or protocols. Clinical education gives positive effect and greatly determines the improvement of understanding on radiology interpretation, understanding of dosage optimization, and reduction of error percentage when making radiographic imaging. This literature review gave evidence that there was impact from clinical education toward achievement of dentistry radiology competency of professional student.
