Abstract: Background and Purpose: dental caries is the most common chronic disease in the world and the rate of dental caries in many developing countries, it is considered as a health problem. Radiography is one of the best diagnostic tools in dentistry ending in accurate diagnostic procedures. Bitewing Radiography is considered as the gold standard for caries diagnostics nowadays. Last year students - who have completed most of their theoretical and practical courses - should have the ability to interpret radiographies. Hence, measuring the last year students' abilities can effectively help increase the level of knowledge and knowledge of future dentists. Materials and Methods: The study was cross-sectional. In this study, 100 radiographs of molars and premolars teeth were collected. First, the professors approved their radiology department, and then the graphs were given to all students of the year. The students wrote their results on proximal lesions of each tooth according to the criteria obtained on the paper. Data were analyzed using SPSS-24. Results: The mean percent of correct diagnosis of proximal caries in maxilla was 75.00% ± 19.43% in in mandible 71.66 ± 21.13%. There were no significant differences in the rate of caries diagnosis by the last year students. Conclusion: the correct diagnosis of caries among students was 78.86%. Additionally, the mean of correct detection in maxilla was higher than mandible, but statistically insignificant.
