Cambodia Dentistry Exit Exam study guide
Cambodia Dentistry Exit Exam · Work through your exam, one topic at a time.
The Cambodia Dentistry Exit Exam is the national assessment that dental graduates in Cambodia are expected to pass before practising independently, and it functions as the bridge between the university curriculum and licensure through the Ministry of Health. It is intended for final-year students at Cambodian dental schools and for graduates returning to sit the examination, including those who trained abroad and need recognition of their qualification. The Cambodia Dentistry Exit Exam study guide has 12 sections and about 4,262 words.
01Oral and Maxillofacial Anatomy and Histology
Anatomy and histology questions in the Cambodian exit exam are rarely pure recall: they ask you to connect a structure to a clinical risk - which nerve runs where, which tissue layer is being cut, which developmental stage explains an anomaly. Tooth development passes through bud, cap and bell stages.
356 words, about 2 min02Oral Pathology and Oral Medicine
The exam tests whether you can separate a clinical descriptive term from a histological diagnosis, recognise red flags for malignancy, and match immune-mediated diseases to their microscopic level of separation. Leukoplakia and erythroplakia are clinical diagnoses of exclusion: a white or red patch that cannot be attributed to any other disease.
362 words, about 2 min03Restorative Dentistry and Endodontics
Expect questions on cavity design principles, adhesion to enamel versus dentine, pulp protection decisions, working length determination, irrigant choice and obturation quality. Enamel bonding relies on acid etching creating microporosity; dentine bonding must first manage the smear layer, either removing it (etch-and-rinse) or modifying it (self-etch).
360 words, about 2 min04Prosthodontics
The exam probes whether you can distinguish retention, support and stability, apply Applegate's rules and Kennedy classification, and justify design choices for removable and fixed prostheses. Retention resists vertical displacement, support resists vertical seating force, stability resists horizontal and rotational movement.
361 words, about 2 min05Periodontology
Questions focus on the 2017 classification (stage and grade), the difference between gingivitis and periodontitis, risk factors, and the sequence from non-surgical to surgical therapy and maintenance. Gingivitis is reversible inflammation confined to the gingiva with no clinical attachment loss.
366 words, about 2 min06Oral and Maxillofacial Surgery
The exam checks surgical decision-making: when to extract, how to plan an impacted third molar, how to recognise and manage complications, and how to handle odontogenic infection and trauma. Pre-extraction assessment: medical history and anticoagulant status, radiographic relationship to the inferior alveolar canal and maxillary sinus, root morphology, bone density and access.
356 words, about 2 min07Orthodontics and Pediatric Dentistry
Expect questions on normal occlusal development, space analysis in the mixed dentition, interceptive measures, and the management of caries and trauma in children. Angle classification is based on the first permanent molar relationship: Class I, Class II (division 1 or 2), Class III.
381 words, about 2 min08Dental Public Health
This domain tests population-level thinking: how to measure oral health need, how to plan and evaluate a community programme, and how the Cambodian oral health system is organised. Dental public health works through assessment, policy development and assurance.
346 words, about 2 min09Epidemiology and Prevention
Questions test whether you can choose the right measure of frequency or association, interpret a diagnostic test, and apply levels of prevention to a real population. Prevalence is the proportion with disease at a point in time; incidence is new cases over a period.
340 words, about 2 min10Pharmacology
Examinations in Cambodia frequently test maximum local anaesthetic doses, antibiotic choice and prophylaxis, analgesic selection, and drug interactions relevant to dentistry. Amide local anaesthetics (lidocaine, mepivacaine, articaine, bupivacaine) are metabolised in the liver; esters are metabolised by plasma esterases and are more allergenic.
340 words, about 2 min11Anesthesia and Infection Control
Questions combine technique with safety: which block to use, what can go wrong, and how to sterilise, disinfect and protect yourself and the next patient. Inferior alveolar nerve block targets the pterygomandibular space; the Gow-Gates and Vazirani–Akinosi techniques are alternatives when the conventional block fails or access is limited.
351 words, about 2 min12Clinical Diagnosis, Treatment Planning and Emergency Care
This domain integrates everything: can you take a focused history, form a differential, sequence a plan, obtain consent, and manage a patient collapsing in the chair? Structure the record: chief complaint, history of the complaint, medical and drug history, examination, investigations, diagnosis, plan.
