AAOMS will offer the National Board of Medical Examiners Comprehensive Basic Science Examination in February and July, granting training programs an enhanced method to evaluate candidates for positions.
The exam is open to all dental students interested in applying to oral and maxillofacial surgery residencies and allows applicants to measure their understanding of basic science. Please note AAOMS now limits the number of times the Comprehensive Basic Science Examination can be taken to six.
