- Treatment Planning is Key: Beyond diagnosis, you must demonstrate the ability to formulate logical and evidence-based treatment plans.
- Master Dental Materials: A thorough understanding of the properties, indications, and contraindications of common dental materials is essential.
- Medical Emergencies are Fair Game: Be prepared to manage common medical emergencies that can occur in a dental setting (e.g., syncope, anaphylaxis, hypoglycemia).
- Radiographic Interpretation is a Core Skill: You must be proficient in interpreting various dental radiographs, from periapical to OPGs and CBCT basics.
Deconstructing the 2025 DHA Dental Exam Blueprint
A winning strategy begins with a thorough understanding of the examination’s structure and content. The DHA exam for General Dentists is a Computer-Based Test (CBT) that typically consists of 150 MCQs to be completed in 165 minutes. The questions are designed to simulate real-world clinical practice. For a detailed guide on the initial steps, refer to our article on how to prepare for the dental Prometric exam.
Content Domain Breakdown
The exam is designed to be a comprehensive test of a general dentist’s capabilities. A well-rounded study plan should allocate significant time to each of these core areas:
| Domain | High-Yield Topics and Concepts |
|---|---|
| Operative Dentistry & Cariology | Caries diagnosis (ICDAS), principles of cavity preparation (G.V. Black’s classification), dental materials (amalgam, composites, glass ionomers), pulp capping procedures, and management of tooth hypersensitivity. |
| Endodontics | Diagnosis of pulpal and periapical diseases, root canal treatment procedures (access, cleaning, shaping, obturation), management of traumatic dental injuries, and endodontic emergencies (e.g., abscess). |
| Prosthodontics | Principles of fixed prosthodontics (crowns, bridges), impressions materials and techniques, complete and removable partial dentures (design, function), and basics of implant dentistry. |
| Oral Surgery & Pain Control | Simple and surgical extractions, management of impacted teeth (especially third molars), local anesthesia (pharmacology, techniques, complications), diagnosis and management of common oral lesions, and post-operative care. |
| Periodontics | Diagnosis and classification of periodontal diseases, non-surgical periodontal therapy (scaling and root planing), principles of periodontal surgery (e.g., gingivectomy, flap surgery), and understanding the link between periodontal disease and systemic health. |
| Pediatric Dentistry (Pedodontics) | Management of caries in the primary dentition, pulp therapy for primary teeth (pulpotomy, pulpectomy), space maintainers, and behavioral management techniques. For more specialized information, see our guide on key topics for the pediatric dentistry exam. |
| Orthodontics | Angle’s classification of malocclusion, identification of skeletal and dental discrepancies, common orthodontic appliances, and recognizing the need for specialist referral. |
| Oral Medicine, Pathology & Radiology | Diagnosis of common oral mucosal lesions (e.g., aphthous ulcers, oral candidiasis, lichen planus), radiographic interpretation of pathology (cysts, tumors), and understanding oral manifestations of systemic diseases. |
Treat every practice question as a mini case study. Identify the patient’s chief complaint, relevant history, and key clinical findings before you even look at the options. This systematic approach prevents errors.
Strategic MCQ Deconstruction: In-Depth Examples & Rationales
To truly excel, you must learn to think like the exam creators. Let’s analyze the types of questions you will face. The best way to develop this skill is with a dedicated prometric dental licensing exam QBank.
1. The Diagnostic Challenge Question
Sample Question 1: Diagnosis
A 45-year-old female patient complains of a burning sensation on her tongue and bilateral white, lace-like striations on her buccal mucosa. The lesions are asymptomatic and were discovered during a routine check-up. The patient has a history of well-controlled hypertension. What is the most likely diagnosis?
- Oral Candidiasis
- Lichen Planus
- Leukoplakia
- Pemphigus Vulgaris
Correct Answer: B
Rationale: The clinical description of bilateral, asymptomatic, white, lace-like striations (known as Wickham’s striae) on the buccal mucosa is the classic presentation of reticular oral lichen planus. It is a common chronic inflammatory condition. While it can sometimes be erosive and painful, this reticular form is often found incidentally.
Why other options are incorrect:
A: Oral candidiasis typically presents as a pseudomembranous white plaque that can be wiped off, leaving an erythematous base, or as an erythematous form. It doesn’t typically form a lace-like pattern.
C: Leukoplakia is a clinical term for a white patch that cannot be characterized as any other disease. It is typically a more homogenous or speckled plaque and is considered pre-malignant, requiring biopsy. It does not have a striated appearance.
D: Pemphigus vulgaris is a severe autoimmune blistering disease that presents with painful bullae and erosions, not fine white lines.
2. The “Most Appropriate Treatment” Question
Sample Question 2: Treatment Planning
A 7-year-old child presents with a deep carious lesion on the primary mandibular first molar. A periapical radiograph reveals that the caries is close to the pulp, but there is no evidence of a periapical abscess or internal/external root resorption. The tooth is asymptomatic. What is the most appropriate treatment?
- Indirect Pulp Cap
- Pulpotomy
- Pulpectomy
- Extraction
Correct Answer: B
Rationale: For a primary tooth with deep caries approaching a vital, asymptomatic pulp without signs of irreversible pulpitis or necrosis, a pulpotomy is the treatment of choice. The procedure involves removing the coronal pulp tissue, placing a medicament (like formocresol or MTA) over the radicular pulp stumps, and placing a definitive restoration (typically a stainless steel crown).
Why other options are incorrect:
A: An indirect pulp cap is an option when the caries is still in dentin and a small layer is left over the pulp, but a pulpotomy is preferred when the caries is very deep and exposure is likely.
C: A pulpectomy (complete removal of pulp tissue from crown and roots) is indicated for a primary tooth with signs of irreversible pulpitis or necrosis.
D: Extraction would be considered if the tooth were non-restorable or if there was significant pathology, which is not the case here. Preserving the primary molar is crucial for space maintenance.
3. The Dental Materials & Principles Question
Sample Question 3: Dental Materials
Which of the following components of a resin composite is responsible for coupling the filler particles to the resin matrix?
- Bis-GMA
- TEGDMA
- Silane
- Camphorquinone
Correct Answer: C
Rationale: Silane is a coupling agent. It is a bifunctional molecule that forms a chemical bond with both the inorganic filler particles (like silica or glass) and the organic resin matrix. This bond is critical for transferring stress from the weaker resin to the stronger filler particles, thereby improving the material’s mechanical properties and longevity.
Why other options are incorrect:
A: Bis-GMA (bisphenol A-glycidyl methacrylate) is the primary monomer that forms the bulk of the organic resin matrix.
B: TEGDMA (triethylene glycol dimethacrylate) is a diluent monomer used to reduce the viscosity of the Bis-GMA, making the composite easier to handle.
D: Camphorquinone is the photoinitiator. It is the molecule that absorbs blue light from the curing unit and starts the polymerization reaction.
Building Your High-Impact Study Schedule
A disciplined, multi-phased approach will ensure you cover all necessary material without burnout. An effective study plan is a cornerstone of DHA Prometric exam preparation.
- Phase 1: Comprehensive Content Review (6-8 weeks): Divide your studies by specialty. Dedicate 3-4 days to each major topic (e.g., Endodontics, Prosthodontics, etc.). Use reputable textbooks (like Cohen’s for Endo, Shillingburg for Fixed Pros) and review notes. The goal is to rebuild your foundational knowledge.
- Phase 2: Intensive MCQ Practice (5-7 weeks): This is the most vital phase. Subscribe to a high-quality, specialized dental QBank. Start with untimed, tutor-mode blocks to understand the concepts. Gradually transition to timed blocks of 50 questions to simulate exam conditions. Aim to complete at least 2,500-3,000 questions. Critically analyze every rationale.
- Phase 3: Integration and Simulation (2-3 weeks): In this final phase, focus on your weak areas identified by the QBank analytics. Review key topics like medical emergencies, local anesthesia, and radiographic interpretation. Take at least three full-length, 150-question mock exams under strict timed conditions to perfect your pacing and build mental endurance.
Frequently Asked Questions (FAQs) for the DHA Dental Exam
The exam is graded as Pass/Fail. While the DHA does not publish an official passing percentage, the generally accepted threshold is around 60% to 65%. To be safe, you should aim to consistently score above 70% on your full-length practice exams.
The DHA exam is highly focused on clinical application and evidence-based practice relevant to a general dentist. Compared to some exams that might have a heavier basic science component, the DHA is almost entirely case-based. Its content is similar to exams like the INBDE (USA) or ORE (UK) but tailored to the standards expected in Dubai.
While QBanks provide good practice, supplementing with a dedicated dental radiology atlas or textbook (like White and Pharoah’s Oral Radiology: Principles and Interpretation) is highly recommended. Focus on identifying common pathologies, anatomical landmarks, and technical errors.
All specialties are important, as the exam tests the competency of a general dentist. However, high-yield areas include diagnosis and treatment planning across all fields. You are expected to know when to treat a case and, just as importantly, when to refer to a specialist. For an in-depth look, review our guides on Endodontics MCQs and Prosthodontics MCQs.
No, the exam uses generic names for materials and drugs. You need to know the class of material (e.g., “fifth-generation bonding agent,” “hybrid composite,” “polyether impression material”) and its properties, not a specific brand like “OptiBond” or “Filtek.”
It is critically important. You should be able to calculate the maximum safe dose of common local anesthetics (like Lidocaine and Articaine) based on a patient’s weight and know the maximum number of cartridges that can be safely administered. This is a common safety-related question.
Passing the exam grants you an eligibility letter from the DHA, valid for one year. The next steps involve completing the Primary Source Verification (PSV) process with the DataFlow group and securing a job with a DHA-licensed dental clinic or hospital. Your employer will then proceed with activating your professional DHA license.
Candidates are typically permitted three attempts to pass the DHA examination. If unsuccessful after three tries, you may be required to undertake additional clinical training before being eligible to reapply. Always check the latest official DHA regulations for the most current policy.
The exam reflects a high standard of international care. Familiarity with guidelines from globally recognized bodies is beneficial. For instance, the clinical recommendations published by the American Dental Association (ADA) on various topics (e.g., antibiotic prophylaxis, sealant use) are an excellent and authoritative resource.
The only mandatory item is your original, valid passport. Ensure the name on your passport is identical to the name you used during registration. Digital copies or other forms of ID will not be accepted. The Prometric test center will provide a secure locker for your personal belongings.
