Welcome to the ABE Case History Exam
Important Updates Beginning with the May 2026 Exam Cycle
Please note: There are updates effective for the May 2026 and subsequent exam cycles. It is extremely important that you carefully read the revised Case History Portfolio Examination Guidelines for details and instructions.
IMPORTANT: The updated deadline for the May 2026 Case History Exam is May 1st at 2 P.M. Central Daylight Time (CTD). This deadline will be strictly enforced, and any portfolio submitted past this time will be returned to the candidate and not evaluated in the cycle. Please do not wait to submit your portfolio until the deadline.
Other notable updates are as follows:
- After careful research conducted in association with statisticians with expertise in the field of high stakes exams, the ABE elected to incorporate a new rating scale rubric to begin with the May 1, 2026 exam cycle.
- Each case in a submitted portfolio will be evaluated in ten categories. Examiners will assign one grade per each of these categories. Each case will receive a total of twenty scores (Ten per each examiner). Therefore, each portfolio will receive 50 scores per examiner, and 100 total scores per portfolio. This thorough and more robust process gives the examining Directors ample knowledge and insight into the level of the Candidate’s diagnostic and clinical skills. The new rubric can be found in the updated “Case History Portfolio Examination Guidelines”.
- For Case 5, “Periradicular Surgery”, re-surgery (revision of previous periradicular surgery) is no longer acceptable for any cases completed after May 1, 2026.
Download the latest version of the Case History Portfolio Examination Guidelines from our "Instructions" webpage.
The following are the five required cases for submission:
Case 1 - Nonsurgical Root Canal Treatment - Maxillary Molar
Case 2 - Nonsurgical Root Canal Treatment - Mandibular Molar
Case 3 - Nonsurgical Retreatment - Maxillary or Mandibular Molar
Case 4 - OTHER category
Case 5 - Periradicular Surgery - Maxillary or Mandibular Molar
Case Submission Date Annually on May 1
Portfolios are evaluated only ONE TIME PER YEAR, with the submission deadline of May 1st each year.
Candidates will have access to the website to upload their portfolio at any time during the year. However, the recurring submission deadline will be May 1st at 2 P.M. Central Daylight Time (CDT). Any portfolio that has not been submitted in its entirety by the deadline will not be evaluated during that grading cycle.
Due to an ever-increasing number of portfolios submitted, the ABE may need to limit the number of submissions accepted for review in any given cycle. Any such limitation on submissions would be dynamic and based exclusively on available examiner resources. Any portfolio that meets the scheduled deadline that cannot be reviewed would be automatically held and reviewed the following cycle, with candidate notification by ABE staff. We recommend not waiting until the deadline to submit your portfolio because the sooner you submit your portfolio, the more likely you are to be included in the cycle for which you are submitting.
Additional details on portfolio submission, updated requirements and more can be found on the ABE main website .
