It has 150 single-best-answer multiple-choice questions in English, a 3-hour limit and a 65% passing standard, with results shown provisionally at the test centre. Eligibility requires a recognised dental degree plus a completed orthodontic residency of at least three years, and DataFlow primary source verification is mandatory from 2026. The Prometric exam fee is USD 285 from 1 January 2026. This 100-question bank provides original specialist-level practice across growth, cephalometrics, biomechanics, appliances and interdisciplinary orthodontics.

Sample Qatar DHP Orthodontics Practice Questions

1According to the cephalometric Steiner analysis, an ANB angle of approximately what value indicates a normal (Class I) skeletal relationship?

A.0 degrees

B.2 degrees

C.6 degrees

D.10 degrees

Explanation: In the Steiner analysis the ANB angle is the difference between SNA and SNB and reflects the antero-posterior relationship of the maxilla to the mandible. A value of about 2 degrees represents a normal Class I skeletal pattern; higher values suggest Class II and lower or negative values suggest Class III.

2In Angle's classification, a Class II malocclusion is defined by the relationship of which landmark on the maxillary first molar to the mandibular first molar?

A.The mesiobuccal cusp occludes anterior to the mandibular buccal groove

B.The mesiobuccal cusp aligns with the mandibular buccal groove

C.The distobuccal cusp occludes in the mandibular buccal groove

D.The mesiolingual cusp occludes in the central fossa

Explanation: Angle's classification uses the maxillary permanent first molar as the key. In Class II the mesiobuccal cusp of the maxillary first molar occludes anterior (mesial) to the mandibular buccal groove, meaning the mandibular arch is positioned distally relative to the maxillary arch.

3What is the generally accepted optimal force range for orthodontic tooth movement that favours frontal bone resorption and minimises hyalinisation?

A.Very light forces below 5 g

B.Light continuous forces in the range of about 10 to 150 g depending on tooth and movement

C.Heavy forces above 500 g for all teeth

D.Forces are irrelevant to the type of resorption

Explanation: Optimal orthodontic forces are light and continuous, roughly 10 to 150 grams depending on the tooth and the type of movement, producing controlled pressure that favours frontal (direct) bone resorption. Excessive force occludes the periodontal vessels and causes hyalinisation with delayed undermining resorption.

4The centre of resistance of a single-rooted tooth with a normal periodontium is located approximately where?

A.At the incisal edge

B.At the apex of the root

C.About one-third to 40% of the root length apical to the alveolar crest

D.Outside the tooth in the surrounding bone

Explanation: For a single-rooted tooth with normal bone support, the centre of resistance lies about one-third to 40% of the distance from the alveolar crest toward the apex along the root. Its position moves apically as alveolar bone is lost, which alters the moment produced by a given force.

5Which moment-to-force ratio is required to produce bodily movement (translation) of a tooth, where the crown and root move equal amounts?

A.Approximately 0:1

B.Approximately 7:1

C.Approximately 10:1

D.Approximately 12:1

Explanation: To translate a tooth bodily, the line of action of the net force must pass through the centre of resistance. Because the bracket is coronal to the centre of resistance, a counterbalancing moment is needed; a moment-to-force ratio of about 10:1 produces bodily movement for a typical incisor.

6During pubertal craniofacial growth, the mandible typically grows in which predominant direction relative to the cranial base?

A.Downward and forward

B.Upward and backward

C.Purely transverse

D.It does not change after age 6

Explanation: The mandible is displaced downward and forward as the surrounding soft tissues grow, while condylar cartilage proliferation adds length and height. This downward and forward translation is why mandibular deficiency may partly self-correct during the growth spurt in well-selected Class II patients.

7The cervical vertebral maturation (CVM) method is used in orthodontics primarily to assess what?

A.Dental caries risk

B.Skeletal maturation and the timing of the pubertal growth spurt

C.Periodontal bone loss

D.Salivary flow rate

Explanation: The CVM method evaluates the morphology of the second, third and fourth cervical vertebrae on a lateral cephalogram to estimate skeletal maturity and predict the timing of the pubertal growth spurt. This helps decide the optimal timing for growth-modification treatment.

8In a fixed straight-wire appliance, the term 'tip' built into a bracket refers to which property?

A.Faciolingual inclination of the tooth

B.Mesiodistal angulation of the long axis of the tooth

C.In-out (faciolingual thickness) compensation

D.Rotational control of the tooth

Explanation: In the straight-wire prescription, tip (angulation) is the mesiodistal inclination of the long axis of the tooth, built into the bracket slot angulation. Torque is the faciolingual inclination, and in-out is compensated by varying bracket base thickness.

9A patient presents with a Class II division 2 malocclusion. Which incisor feature is characteristic of this subdivision?

A.Proclined maxillary central incisors with increased overjet

B.Retroclined maxillary central incisors, often with deep overbite

C.An anterior open bite

D.A reverse overjet

Explanation: Class II division 2 is characterised by retroclined maxillary central incisors, frequently with the lateral incisors proclined or mesiolabially rotated, and a deep overbite. The overjet is usually normal or reduced, distinguishing it from division 1 where incisors are proclined with increased overjet.

10Which functional appliance is a tooth-borne, fixed (non-removable) device commonly used to correct Class II malocclusion in growing patients?

A.Removable Hawley retainer

B.Herbst appliance

C.Quad-helix

D.Nance holding arch

Explanation: The Herbst appliance is a fixed, tooth-borne functional appliance that holds the mandible in a protruded position continuously to correct Class II malocclusion in growing patients. Its fixed nature removes reliance on patient compliance, unlike removable functional appliances.

About the Qatar DHP Orthodontics Exam

The Qatar DHP Orthodontics Specialist Qualifying Exam is the Prometric-delivered licensing examination that dentists must pass to register as a specialist orthodontist with the Department of Healthcare Professions under Qatar's Ministry of Public Health.

Qatar DHP Orthodontics Study Tips from Top Performers

1Anchor your revision in core texts such as Proffit's Contemporary Orthodontics and Graber, then layer in recent journal evidence on aligners and temporary anchorage devices.

2Drill cephalometric norms until SNA, SNB, ANB, the mandibular plane angle and the Wits appraisal are automatic; many MCQs hinge on interpreting one or two values.

3Practise biomechanics with force-system diagrams: know centre of resistance, moment-to-force ratios and how they produce tipping, translation or root movement.

4Build a one-page summary of optimal force ranges and the histology of tooth movement, including hyalinisation and undermining versus frontal resorption.

5Revise malocclusion management by class: typical Class II division 1, Class II division 2 and Class III approaches in growing versus non-growing patients.

6Time yourself at roughly 72 seconds per question so you can finish 150 items in three hours and leave time to review flagged questions.
