Iran Dental Residency Entrance Exam

It is a single written paper of multiple-choice questions delivered in Persian, covering all listed dental and basic-science domains in one sitting. Expect four- and five-option items, with some image- or case-based stems in pathology, radiology and diagnosis. The official body confirms the exact structure each cycle.

These change between cycles, so there is no reliable fixed number to quote. The examining body publishes the current question count and time limit in its official announcement before registration. Plan your pacing from that document, not from what previous candidates remember.

The paper is demanding because it spans twelve domains and rewards recall speed as much as depth. Selection is competitive and effectively rank-based: your score is compared with other applicants competing for limited specialty seats. The official body defines any minimum score or cut-off, so check its current rules.

Retake rules are set by the examining authority and can change, so confirm eligibility and any limits in the current announcement. In practice many candidates sit it more than once, and repeat candidates usually gain most by fixing weak domains rather than re-reading what they already know.

Start with the high-weight clinical cores - endodontics, periodontics, fixed prosthodontics, restorative and materials, and oral pathology - because they decide most of your score. Then add oral medicine, radiology, removable prosthodontics, pediatric dentistry and orthodontics, and keep basic sciences as short spaced reviews rather than a late cram.

Three recur: neglecting one high-weight domain because it feels unfamiliar, reading without timed practice so accuracy collapses under pressure, and over-investing in low-yield basic-science detail while clinical topics stay shallow. Image-based pathology and radiology items also catch candidates who only studied text.

Use them as a diagnostic, not a scoreboard. Do mixed timed blocks, log every wrong answer by domain and by cause - unknown fact, misread stem, or slow recall - and revisit those topics in your textbooks. Re-test the same weak areas after two weeks to confirm the fix held.

Only the official examining body's website and its current cycle announcement are authoritative for registration dates, fees, question counts, time limits and scoring. This page is independent study material and does not publish or guarantee those figures.
