DOH Orthodontics Exam 2026: Syllabus, Eligibility & MCQs

DOH Orthodontics Exam Quick Summary

The DOH (Department of Health) Abu Dhabi Orthodontics specialty exam covers growth and development, biomechanics, malocclusion diagnosis and treatment, and orthognathic considerations, with 100 MCQs, 2 hours to complete, and a passing score of 65% -- followed by an oral/viva examination. It's delivered via Pearson VUE test centers, not Prometric.

DOH / HAAD Abu Dhabi Orthodontics Specialty Exam

The Department of Health (DOH) Abu Dhabi -- previously known as the Health Authority of Abu Dhabi (HAAD) -- administers this specialty exam through Pearson VUE testing centers to evaluate a candidate's diagnostic and treatment-planning skills in orthodontics: the branch of dentistry concerned with correcting malocclusion and irregularities of the teeth and jaws. The exam consists of a written MCQ component followed by an oral/viva examination -- successful candidates receive an Orthodontic dental license to practice in Abu Dhabi.

Booking note: DOH exams run on Pearson VUE, not Prometric -- see our full DOH exam registration guide for the step-by-step TAMM account, DataFlow, and Pearson VUE scheduling process.

Eligibility criteria for the DOH Orthodontics exam

To apply for the DOH Orthodontics specialist exam, candidates are generally expected to meet the following (see our DOH exam eligibility requirements for dentists for the full general-dentistry baseline these specialist criteria build on):

Primary dental degree: A recognized BDS, DDS, or equivalent dental degree from an accredited institution.

Specialization in Orthodontics: A recognized postgraduate qualification in Orthodontics -- MDS, MSc, or equivalent -- from an accredited institution. Clinical-based degrees are required; research-only degrees are generally not accepted.

Post-specialization clinical experience: Foreign-trained/non-UAE-national applicants generally need a minimum of 3 years of clinical experience in orthodontics after completing their specialization.

Valid license & Good Standing Certificate: An active license to practice in your home country (or country of last employment), plus a Certificate of Good Standing typically valid within the last 6 months.

DataFlow Primary Source Verification: All educational, professional, and licensing documents must be verified through DataFlow, with a positive PSV report. Our DOH credentialing process guide walks through this step in detail.

The exam fee is around AED 450, and DOH generally allows up to 3 total attempts for the same specialty, shared across DHA, DOH, and MOH combined -- so a failed attempt at one authority can count against your total elsewhere too.

DOH Orthodontics exam exemption criteria

Possible exam exemption -- confirm before relying on it

DOH evaluates exemption from the written exam on a case-by-case basis for holders of certain high-level professional certifications, including US board certification, UK CCT, Canadian Royal College fellowship, and Australian/New Zealand fellowship. Published DOH exemption guidance does not specifically name a dental fellowship or board (such as FDSRCS or an American Board of Dental Specialties certification, e.g. the American Board of Orthodontics) as automatically qualifying under this route -- unlike some other Gulf authorities' dentist-specific exemption lists. If you hold one of the certifications above, or a dental-specific fellowship you believe may qualify, confirm your exemption status directly with DOH or through a DataFlow/licensing consultant before assuming it applies.

See our DOH specialist exam exemption criteria guide for the full list of qualifying certifications.

DOH Orthodontics exam syllabus

DOH has not published an Orthodontics-specific topic weightage breakdown of its own (see our general DOH exam subjects and format guide for how this fits into the wider dental exam structure). The exam draws on the same core clinical subject areas used across Gulf orthodontics specialist exams generally:

Growth & Development
Etiology of Malocclusions
Cephalometric Analysis
Biomechanics and Biology of Tooth Movement
Interceptive Orthodontic Treatment
Comprehensive Treatment in Preadolescents and Adolescents
Adult and Adjunctive Orthodontics
Orthognathic Surgery
Craniofacial Deformities
Special Considerations in Orthodontics
Retention and Stability
Ethics and Professionalism
Patient Safety

Most questions are clinical scenario-based MCQs with 4 answer options and a single correct answer, with no negative marking. Exact topic weighting can differ from DHA, SDLE, QCHP, and NHRA versions of the same specialty exam.

DOH specialist dental exams are delivered as computer-based tests via Pearson VUE test centers (not Prometric), followed by an oral/viva examination. The exact question count, duration, and passing score can differ from DHA, QCHP, SDLE, and NHRA versions of the same specialty exam -- always confirm the DOH-specific figures on your own eligibility notice rather than assuming they match another authority's exam.

Preparation tips for the DOH Orthodontics exam

Prepare for the oral/viva, not just MCQs

DOH's orthodontics exam includes an oral component after the written test -- practice explaining your diagnostic and treatment-planning reasoning out loud, not just picking the right answer.

Prioritize comprehensive treatment & interceptive care

These are consistently the most heavily weighted topics across Gulf orthodontics exams -- build strong fundamentals here first.

Get comfortable with cephalometric analysis

Landmark identification and angular measurements (SNA, SNB, ANB) come up repeatedly -- practice reading tracings quickly and accurately.

Pace yourself

With 100 questions in 2 hours, you have just over a minute per question -- since there's no negative marking, never leave a question blank.

Sample Practice MCQs

Test your knowledge with these original clinical scenario-style questions. Tap a question to reveal the answer.

> Question 1: Functional Appliance Therapy

A growing patient presents with a Class II Division 1 malocclusion caused by mandibular retrognathia, with good growth potential remaining. What is the most appropriate interceptive treatment?

Answer: A functional appliance (such as a Twin Block or Herbst appliance) to encourage mandibular growth and correct the sagittal discrepancy during the growth spurt.

Explanation: Class II Division 1 cases driven by mandibular deficiency respond best to functional appliance therapy timed to the patient's growth spurt, since these appliances work by influencing condylar growth and posturing the mandible forward -- an option only available while significant growth potential remains, unlike in a non-growing adult.

> Question 2: Cephalometric Analysis

A cephalometric tracing shows an SNA angle of 84° and an SNB angle of 76°, giving an ANB angle of 8°. What skeletal relationship does this indicate?

Answer: A Class II skeletal relationship, caused by mandibular retrognathia (SNB is low) relative to a roughly normal maxillary position (SNA is close to the average of 82°).

Explanation: ANB angle reflects the anteroposterior relationship between the maxilla and mandible; a normal ANB is roughly 2°, so 8° indicates a significant Class II skeletal discrepancy. Because SNA is near-normal while SNB is notably reduced, the discrepancy is attributable mainly to mandibular retrognathia rather than maxillary protrusion.

> Question 3: Retention and Stability

After completing comprehensive orthodontic treatment for a patient with severe pre-treatment rotations of the mandibular incisors, what is the most important consideration for long-term retention?

Answer: Extended or permanent retention is needed, since rotated teeth (especially incisors) have a high relapse tendency due to slow reorganization of the supracrestal (transseptal) fibers.

Explanation: Rotational corrections are among the least stable orthodontic movements because the gingival and periodontal fibers stretched during rotation take much longer to reorganize than bone remodeling does, and may never fully reorganize. This makes longer-term or permanent retention (rather than a standard fixed retention period) the appropriate plan for severely rotated teeth.

Frequently Asked Questions

> What does the DOH Orthodontics exam cover?

It covers growth and development, etiology of malocclusions, cephalometric analysis, biomechanics, interceptive and comprehensive orthodontic treatment, adult/adjunctive orthodontics, orthognathic surgery, craniofacial deformities, retention and stability, ethics and professionalism, and patient safety.

> Is the DOH Orthodontics exam held at Prometric or Pearson VUE?

Pearson VUE. This is different from DHA, MOH, and SLE, which use Prometric -- booking a Prometric seat by mistake is one of the most common errors DOH candidates make, so confirm your test center before scheduling.

> Does the DOH Orthodontics exam include an oral or viva component?

Yes -- unlike some other DOH dental specialty exams where this isn't clearly confirmed, the Orthodontics exam is described as a written MCQ test followed by an oral/viva examination. Prepare to defend your diagnostic and treatment-planning reasoning verbally, not just answer multiple-choice questions.

> What is the passing score for the DOH Orthodontics exam?

Candidates generally need to score 65% or above to pass -- note that this can differ from DHA and other Gulf authorities' versions of the same specialty exam, so don't assume figures from another authority apply to DOH.

> Can orthodontists be exempted from the DOH exam?

Possibly, but only under DOH's general case-by-case exemption route for certain high-level board certifications (US board, UK CCT, Canadian Royal College fellowship, Australian/NZ fellowship) -- published guidance does not confirm that dental-specific fellowships automatically qualify. Confirm your own status directly with DOH before relying on it.

> How many attempts do I get, and what does the exam cost?

The exam fee is around AED 450, and DOH generally allows up to 3 total attempts for the same specialty -- shared across DHA, DOH, and MOH combined, so attempts at one authority count toward your overall limit.

> Are official DOH Orthodontics past papers available?

No -- DOH does not release official past papers publicly. Recall-based question banks compiled from actual test takers' feedback are the closest available preparation resource.
