MOHAP Dentist Exam study guide
MOHAP Dentist Exam · Work through your exam, one topic at a time.
The MOHAP Dentist Exam is the licensing assessment used by the UAE Ministry of Health and Prevention for dentists seeking registration to practise in the Northern Emirates. It is aimed at internationally trained and locally trained dental graduates who need to demonstrate that their knowledge meets UAE entry-to-practice expectations before registration is granted. The MOHAP Dentist Exam study guide has 10 sections and about 3,602 words.
01Basic and Applied Biomedical Sciences
Questions in this domain test whether you can connect structure to function and mechanism to clinical consequence. Prioritise: anatomy of the head and neck (cranial nerve branches and their foramina, the pterygopalatine fossa, the course of the inferior alveolar and lingual nerves, venous drainage and the cavernous sinus, fascial spaces of the neck); physiology (action potential and nerve conduction, cardiac output and blood pressure regulation, renal handling of sodium and water, acid–base compensation, calcium homeostasis via PTH and vitamin D, haemostasis); histology (epithelial types and junctions, the four periodontal tissues, bone remodelling units, dental pulp organisation); biochemistry (glycolysis, Krebs cycle, oxidative phosphorylation, enzyme kinetics, collagen synthesis and vitamin C, porphyrin and bilirubin pathways); microbiology (Gram-positive vs Gram-negative structure, virulence factors, sterilisation vs disinfection, common oral flora); pathology (inflammation, wound healing, neoplasia nomenclature, cell injury and apoptosis); and pharmacology (receptor types, pharmacokinetics - first-order elimination, half-life, volume of distribution - and the drug classes used daily: local anaesthetics, NSAIDs, antibiotics, anticoagulants, bisphosphonates).
346 words, about 2 min02Oral Biology
Oral biology links embryology, histology and physiology of the oral tissues. Candidates should be able to describe tooth development (initiation, bud, cap, bell; the enamel knot as signalling centre; reciprocal epithelial–mesenchymal induction), the dental lamina and successional lamina , and the timing of mineralisation.
317 words, about 2 min03Oral Pathology and Oral Medicine
Use a systematic scheme for every lesion: site, size, colour, surface, consistency, duration, associated symptoms, and systemic context . Learn the classic ulcer differential (recurrent aphthous, traumatic, herpes, squamous cell carcinoma, drug-related, haematological) and the classic white patch differential (frictional keratosis, leukoplakia, candidiasis, lichen planus, nicotine stomatitis, squamous cell carcinoma).
328 words, about 2 min04Cariology, Operative Dentistry and Endodontics
Understand the dynamic demineralisation–remineralisation balance , the Stephan curve (pH falls after sugar exposure and recovers with saliva), the role of fluoride (topical effect, fluorapatite formation, inhibition of demineralisation, enhancement of remineralisation, antibacterial effect), and the caries risk assessment approach. Know ICDAS and caries detection methods (visual-tactile, bitewing radiographs, transillumination, fluorescence).
345 words, about 2 min05Periodontology
Know the anatomy of the periodontium and the clinical parameters : probing depth, clinical attachment level, bleeding on probing, plaque index, recession, and mobility. Understand the 2017 World Workshop classification - periodontal health, gingivitis (plaque-induced, non-plaque-induced), periodontitis (staging I–IV by severity and complexity, grading A–C by rate of progression and risk), and the peri-implant categories (peri-implant health, mucositis, peri-implantitis).
320 words, about 2 min06Prosthodontics (Fixed and Removable)
Know treatment planning principles : occlusal analysis, abutment selection, ferrule, crown-to-root ratio, periodontal support, and the biologic width (about 2 mm) that governs margin placement. Know tooth preparation principles: taper (ideally 6–10°), reduction (occlusal 1.5–2 mm, axial 1–1.5 mm), finish line types (chamfer, shoulder, knife-edge) and their indications, and the need for resistance and retention form .
333 words, about 2 min07Oral and Maxillofacial Surgery and Anesthesia
Know exodontia : indications, contraindications, forceps and elevators, the principles of expansion, wedging and leverage , and the management of complicated extractions (root fracture, retained root, oro-antral communication). Know third molar assessment (Winter's and Pell–Gregory classifications, inferior alveolar nerve proximity, coronectomy as an option).
307 words, about 2 min08Orthodontics and Pediatric Dentistry
Know growth and development of the craniofacial complex, the mixed dentition analysis (space analysis, Bolton, Tanaka–Johnston), and the timing of interceptive treatment . Know the Angle classification of malocclusion and the concept of skeletal versus dental discrepancy.
340 words, about 2 min09Diagnosis, Treatment Planning and Dental Radiology
Know the diagnostic process : history (chief complaint, HPI, medical, dental, social, family), examination (extraoral, intraoral, periodontal, occlusal), special tests (vitality, percussion, palpation, transillumination, selective anaesthesia), and imaging. Know problem list construction and the hierarchy of treatment - emergency, disease control, definitive care, maintenance.
323 words, about 2 min10Infection Control, Patient Safety and Emergency Management
Know the chain of infection and standard precautions - treat every patient as potentially infectious. Know hand hygiene (WHO five moments), PPE (gloves, mask, eye protection, gown), sharps safety , and immunisation of staff (HBV, and post-exposure protocols).
