Qualifying Examination Overview
These study notes are designed to help candidates prepare for the Qualifying Examination (QE) in dentistry. The QE assesses foundational knowledge across biomedical sciences, clinical dentistry, and professional ethics. The notes are based on official sources and are structured to highlight key concepts, clinical applications, and common pitfalls. Candidates should verify specific exam details (e.g., pass mark, format) with the official examining body.
For Dental Conquer practice planning, this module is tracked as 80 questions over about 120 minutes with a listed pass mark of 70%. Treat those numbers as practice baselines and verify the current official format before scheduling.

Biomedical Sciences and Craniofacial Anatomy
Syllabus Focus
- Head and neck anatomy
- Oral embryology and histology
- Craniofacial growth and development
- Neuroanatomy relevant to dentistry
- Systemic physiology and pathology
Key Notes
- Understand the spatial relationships of cranial nerves, especially trigeminal (V), facial (VII), glossopharyngeal (IX), and hypoglossal (XII).
- Know the blood supply of the maxilla and mandible: maxillary artery branches (e.g., infraorbital, posterior superior alveolar).
- Embryologic development of the face: pharyngeal arches, prominences, and common anomalies (cleft lip/palate).
- Histology of enamel, dentin, pulp, cementum, and periodontal ligament: formation, composition, and age-related changes.
- Craniofacial growth patterns: Enlow's counterpart analysis, functional matrix theory, and clinical implications for malocclusion.
- Systemic conditions with oral manifestations: diabetes, osteoporosis, autoimmune diseases (e.g., Sjögren's syndrome).
Must Know
- Bony landmarks: infraorbital foramen, mental foramen, mandibular foramen, and their clinical relevance for local anesthesia.
- Muscles of mastication: temporalis, masseter, medial and lateral pterygoids - origin, insertion, innervation, action.
- Temporomandibular joint anatomy: disc, ligaments, movements, and common disorders.
- Salivary glands: parotid, submandibular, sublingual - ductal anatomy, innervation, and secretory function.
Clinical and Exam Application
- Local anesthesia techniques: inferior alveolar nerve block, maxillary infiltration - correlate with nerve pathways.
- Radiographic interpretation: identify anatomical landmarks (e.g., maxillary sinus, mandibular canal) on panoramic and periapical images.
- Surgical planning: avoid damaging neurovascular bundles during extractions or implant placement.
High-Yield Distinctions
- Differences between primary and permanent tooth morphology: crown size, root length, pulp chamber shape.
- Contrast between intramembranous and endochondral ossification in the craniofacial skeleton.
- Distinguish between sensory and motor components of cranial nerves: e.g., V3 (mandibular) is both sensory and motor.
Common Pitfalls
- Confusing the mental foramen location (between premolars) with the incisive foramen.
- Misidentifying the parotid duct (Stensen's) opening opposite the maxillary second molar.
- Overlooking the role of the chorda tympani (taste to anterior 2/3 of tongue) in facial nerve anatomy.
Review Tasks
- Label a diagram of the skull with key foramina and their contents.
- Trace the pathway of a local anesthetic from injection site to nerve trunk.
- Create a table comparing primary and permanent tooth eruption sequence and root development.
Pharmacology and Pain Control
Syllabus Focus
- Local anesthetics: mechanism, types, maximum doses
- Analgesics: NSAIDs, acetaminophen, opioids
- Antibiotics: prophylaxis, common regimens
- Anxiolytics and sedation
- Medical emergencies in dental practice
Key Notes
- Local anesthetics are weak bases; they work by blocking voltage-gated sodium channels, preventing nerve depolarization.
- Lidocaine 2% with epinephrine 1:100,000: maximum dose 7 mg/kg (adult), up to 500 mg. Epinephrine prolongs action and reduces systemic toxicity.
- NSAIDs (e.g., ibuprofen) inhibit COX-1 and COX-2; used for mild-to-moderate pain. Acetaminophen is analgesic/antipyretic but weak anti-inflammatory.
- Antibiotic prophylaxis for infective endocarditis: amoxicillin 2 g PO 30-60 min before procedure (for high-risk patients per AHA guidelines).
- Benzodiazepines (e.g., midazolam) are used for conscious sedation; flumazenil is the reversal agent.
- Medical emergencies: syncope (most common), allergic reaction, hypoglycemia, seizure - recognize and manage.
Must Know
- Maximum doses of common local anesthetics: lidocaine, articaine, mepivacaine, bupivacaine.
- Contraindications to vasoconstrictors: severe uncontrolled hypertension, hyperthyroidism, MAOI use.
- Drug interactions: NSAIDs with anticoagulants (increased bleeding risk), epinephrine with beta-blockers (hypertensive crisis).
- Antibiotic coverage for odontogenic infections: penicillin VK or amoxicillin first-line; clindamycin for allergy.
Clinical and Exam Application
- Calculate maximum safe dose for a pediatric patient: weight-based (e.g., lidocaine 4.4 mg/kg without epinephrine).
- Select appropriate analgesic for post-extraction pain: ibuprofen 600 mg q6h, with acetaminophen as adjunct.
- Manage a patient on warfarin: consult INR, consider antibiotic prophylaxis, avoid NSAIDs.
High-Yield Distinctions
- Articaine vs. lidocaine: articaine has higher lipid solubility, better bone penetration, but higher risk of paresthesia.
- COX-1 vs. COX-2 selectivity: traditional NSAIDs inhibit both; COX-2 inhibitors (celecoxib) have less GI side effects.
- Local anesthetic toxicity: CNS effects (tinnitus, perioral numbness) precede cardiovascular collapse.
Common Pitfalls
- Using epinephrine in patients with severe cardiovascular disease without consulting physician.
- Forgetting to aspirate before injection to avoid intravascular administration.
- Prescribing antibiotics for viral infections or non-infected swellings.
Review Tasks
- Memorize maximum doses for lidocaine, articaine, and mepivacaine with and without epinephrine.
- Practice calculating doses for a 25 kg child and a 70 kg adult.
- Review the AHA guidelines for antibiotic prophylaxis and create a quick-reference card.
Clinical Periodontics and Preventive Care
Syllabus Focus
- Periodontal anatomy and histology
- Classification of periodontal diseases
- Non-surgical and surgical therapy
- Preventive dentistry: fluoride, sealants, oral hygiene
- Periodontal-systemic connections
Key Notes
- The periodontium consists of gingiva, periodontal ligament, cementum, and alveolar bone. Healthy sulcus depth ≤3 mm.
- Periodontal disease classification: 2018 AAP/EFP system - stages (I-IV) and grades (A-C) based on severity and risk factors.
- Gingivitis is reversible inflammation without attachment loss; periodontitis involves irreversible attachment loss and bone loss.
- Non-surgical therapy: scaling and root planing (SRP) with ultrasonic and hand instruments; aim to remove biofilm and calculus.
- Surgical therapy: flap surgery, osseous resective surgery, regenerative procedures (GTR, bone grafts).
- Preventive care: topical fluoride (varnish, gel), pit and fissure sealants, patient education on brushing/flossing.
Must Know
- Clinical attachment loss (CAL) measurement: from CEJ to base of pocket. Staging based on CAL, bone loss, and complexity.
- Indications for periodontal probing: six sites per tooth, record bleeding on probing (BOP).
- Risk factors: smoking, diabetes, poor oral hygiene, genetic predisposition, stress.
- Maintenance intervals: typically 3-4 months for periodontitis patients.
Clinical and Exam Application
- Interpret a periodontal chart: identify sites with probing depths ≥5 mm, furcation involvement, mobility.
- Develop a treatment plan: initial therapy (SRP, OHI), re-evaluation at 4-6 weeks, then surgical if needed.
- Counsel a diabetic patient on glycemic control and periodontal health: bidirectional relationship.
High-Yield Distinctions
- Chronic vs. aggressive periodontitis (old classification): now replaced by staging/grading, but aggressive features include rapid bone loss and familial pattern.
- Necrotizing periodontal diseases: NUG (necrotizing ulcerative gingivitis) vs. NUP (periodontitis) - pain, pseudomembrane, fever.
- Peri-implantitis vs. periodontitis: inflammation around implants with bone loss; treatment differs (decontamination, surgery).
Common Pitfalls
- Misdiagnosing gingival hyperplasia (drug-induced, e.g., phenytoin) as periodontitis.
- Failing to detect furcation involvement (use a Nabers probe).
- Overlooking the need for antibiotic therapy in aggressive periodontitis (e.g., metronidazole + amoxicillin).
Review Tasks
- Practice staging and grading periodontitis using case scenarios.
- Review the 2018 classification system and create a summary table.
- Learn the steps of SRP: sequence, instrument selection, and evaluation.
Restorative Dentistry and Dental Materials
Syllabus Focus
- Caries diagnosis and classification
- Amalgam and composite restorations
- Crown and bridge principles
- Dental materials: properties, handling, biocompatibility
- Impression materials and techniques
Key Notes
- Caries classification: ICDAS (0-6), G.V. Black (I-VI), and location (occlusal, proximal, smooth surface).
- Amalgam: high-copper alloys have better corrosion resistance and marginal integrity. Condensation and carving are critical.
- Composite resins: light-cured, bond to tooth via etch-and-rinse or self-etch adhesives. Polymerization shrinkage is a limitation.
- Crown preparation: 1.5-2 mm occlusal reduction, 1 mm axial reduction, chamfer or shoulder margin. Retention and resistance form.
- Fixed partial denture (bridge): abutment selection, connector design, pontic design (e.g., ridge lap, ovate).
- Impression materials: alginate (irreversible hydrocolloid) for study models; polyvinyl siloxane (addition silicone) for final impressions.
Must Know
- Principles of cavity preparation: outline form, resistance form, retention form, convenience form, removal of caries.
- Adhesive dentistry: etch (phosphoric acid 37%), prime, bond. Moist vs. dry bonding technique.
- Glass ionomer cement: chemical bond to tooth, fluoride release, used for liners, bases, and restorations in low-stress areas.
- Cementation: zinc phosphate, resin-modified glass ionomer, self-adhesive resin cement - indications and properties.
Clinical and Exam Application
- Select restorative material for a class II lesion: composite for esthetics, amalgam for high stress (if patient accepts).
- Manage a deep carious lesion: indirect pulp cap (calcium hydroxide liner) vs. direct pulp cap (MTA).
- Take an accurate impression: proper tray selection, material mixing, and handling (e.g., avoid premature removal).
High-Yield Distinctions
- Amalgam vs. composite: amalgam has higher compressive strength, longer longevity; composite has better esthetics and bond strength.
- Etch-and-rinse vs. self-etch adhesives: etch-and-rinse provides stronger bond but technique-sensitive; self-etch reduces post-op sensitivity.
- Porcelain-fused-to-metal (PFM) vs. all-ceramic crowns: PFM has metal substructure for strength; all-ceramic (e.g., lithium disilicate) offers superior esthetics.
Common Pitfalls
- Inadequate proximal contact with composite due to matrix band adaptation.
- Overhanging margins from improper amalgam condensation or composite placement.
- Not accounting for polymerization shrinkage: use incremental layering technique.
Review Tasks
- Practice cavity preparation on typodont teeth for class I, II, and III.
- Compare properties of dental materials using a table: strength, modulus, thermal expansion, wear resistance.
- Review steps for cementing a crown: try-in, cleaning, cement mixing, seating, and removal of excess.
Oral Pathology and Diagnostic Imaging
Syllabus Focus
- Oral mucosal lesions: white, red, pigmented, ulcerative
- Odontogenic cysts and tumors
- Salivary gland pathology
- Radiographic interpretation: caries, periodontal disease, periapical pathology
- Advanced imaging: CBCT, MRI, CT indications
Key Notes
- White lesions: leukoplakia (premalignant), lichen planus (reticular, erosive), candidiasis (pseudomembranous, erythematous).
- Red lesions: erythroplakia (high malignant potential), inflammatory conditions (e.g., mucositis).
- Odontogenic cysts: radicular cyst (most common), dentigerous cyst (around crown of unerupted tooth), odontogenic keratocyst (high recurrence).
- Odontogenic tumors: ameloblastoma (benign but aggressive), odontoma (hamartoma), cementoblastoma.
- Salivary gland tumors: pleomorphic adenoma (most common benign), mucoepidermoid carcinoma (most common malignant).
- Radiographic interpretation: caries appears as radiolucency in enamel/dentin; periodontal bone loss is horizontal or vertical; periapical radiolucency indicates apical periodontitis.
Must Know
- Features of oral squamous cell carcinoma: non-healing ulcer, indurated borders, risk factors (tobacco, alcohol, HPV).
- Radiographic appearance of common lesions: periapical radiolucency (granuloma, cyst), mixed radiolucent-radiopaque (cemento-osseous dysplasia).
- CBCT uses: implant planning, impacted tooth localization, TMJ evaluation, pathology assessment.
- Biopsy techniques: incisional vs. excisional, indications, and handling of specimen.
Clinical and Exam Application
- Differentiate between periapical abscess and periodontal abscess: vitality testing, probing, radiographic signs.
- Identify a dentigerous cyst on panoramic radiograph: well-defined radiolucency surrounding crown of impacted tooth.
- Refer a patient with suspicious oral lesion for biopsy: document size, color, texture, and duration.
High-Yield Distinctions
- Radicular cyst vs. dentigerous cyst: radicular cyst is at apex of non-vital tooth; dentigerous cyst surrounds crown of unerupted tooth.
- Ameloblastoma vs. odontogenic keratocyst: ameloblastoma is multilocular, causes root resorption; OKC is unilocular, has high recurrence.
- Benign vs. malignant salivary gland tumors: benign are slow-growing, mobile; malignant are fixed, painful, cause facial nerve palsy.
Common Pitfalls
- Misinterpreting a normal anatomical structure (e.g., mental foramen) as a periapical lesion.
- Failing to recognize early signs of oral cancer: persistent ulcer >2 weeks.
- Overdiagnosing caries on radiographs: check for overlapping contacts, cervical burnout.
Review Tasks
- Create an atlas of common oral lesions with clinical photos and descriptions.
- Practice interpreting panoramic and periapical radiographs for pathology.
- Learn the WHO classification of odontogenic tumors and cysts.
Patient Management and Professional Ethics
Syllabus Focus
- Patient communication and behavior management
- Medical history and risk assessment
- Informed consent and confidentiality
- Ethical principles: autonomy, beneficence, non-maleficence, justice
- Legal aspects: malpractice, standard of care, record keeping
Key Notes
- Effective communication: active listening, empathy, clear explanations, and managing dental anxiety.
- Medical history review: update at each visit, note allergies, medications, systemic diseases, and social history (smoking, alcohol).
- Informed consent: explain diagnosis, treatment options, risks, benefits, alternatives; document consent.
- Ethical principles: autonomy (patient's right to choose), beneficence (act in patient's best interest), non-maleficence (do no harm), justice (fair treatment).
- Confidentiality: HIPAA (US) or equivalent; share information only with patient's permission.
- Standard of care: what a reasonably prudent dentist would do in similar circumstances; failure constitutes negligence.
Must Know
- Components of a complete patient record: medical/dental history, clinical findings, diagnosis, treatment plan, progress notes, radiographs.
- Signs of abuse/neglect: oral injuries, poor hygiene, unexplained fractures; mandatory reporting in many jurisdictions.
- Dental malpractice: elements - duty, breach, causation, damages. Common claims: failure to diagnose, extraction errors, nerve injury.
- Professional boundaries: avoid dual relationships, maintain appropriate physical contact.
Clinical and Exam Application
- Obtain informed consent for a surgical procedure: use simple language, allow questions, and have witness sign.
- Manage a patient with dental phobia: use tell-show-do, relaxation techniques, consider sedation.
- Handle a patient complaint: listen, apologize if appropriate, offer corrective treatment, document.
High-Yield Distinctions
- Ethical vs. legal obligations: ethics may require more than law (e.g., treating emergency patients regardless of ability to pay).
- Implied consent vs. expressed consent: implied for routine exam; expressed (written) for invasive procedures.
- Confidentiality exceptions: when required by law (e.g., child abuse, infectious disease reporting) or to protect patient/public.
Common Pitfalls
- Failing to document refusal of treatment or missed appointments.
- Assuming consent is valid without discussing risks specific to the patient (e.g., bleeding risk on anticoagulants).
- Breaching confidentiality by discussing cases in public areas.
Review Tasks
- Review your jurisdiction's dental practice act and code of ethics.
- Practice writing a progress note using SOAP format.
- Role-play informed consent for a complex treatment plan.
How To Use These Notes With Practice Questions
Do not jump straight from reading to a full mock. Work by subject first: review the key notes, make a short recall sheet from memory, then answer a focused question set. After each miss, decide whether the problem was missing knowledge, poor clinical sequencing, weak source-rule recall, or a distractor you failed to eliminate.
Dental Conquer's question bank, flashcards, mind maps, and spaced review tools are most useful after this instruction layer because they reveal which parts of the notes are not yet retrievable.
Final Review Checklist
- Review all subject summaries and focus on areas where you feel less confident.
- Practice with case-based scenarios to integrate knowledge across subjects.
- Use official source materials to verify any uncertain details.
- Create a study schedule that allocates time to each subject based on your strengths and weaknesses.
