Written Examination Overview
These study notes are designed to help candidates prepare for the Written Examination (WE) as part of dental board certification or licensure. The notes cover six core subjects, each with key concepts, clinical applications, and high-yield distinctions. Candidates should verify all exam-specific details (format, pass mark, dates, eligibility) with the official examining body, as the practice baseline (80 questions, 120 minutes, 70% pass mark) is for reference only.
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.

Oral Anatomy and Morphology
Syllabus Focus
- Tooth morphology and identification
- Occlusion and articulation
- Oral cavity structures
- Developmental anomalies
Key Notes
- Permanent dentition: 32 teeth; primary dentition: 20 teeth. Each tooth has specific anatomical features (cusp, fossa, ridge) that aid in identification.
- Universal numbering system (1-32 for permanent, A-T for primary) is widely used in the US; FDI system (two-digit) is international.
- Occlusal relationships: Class I (neutroclusion), Class II (distoclusion), Class III (mesioclusion) per Angle's classification.
- Key landmarks: cementoenamel junction (CEJ), pulp chamber morphology varies by tooth type (e.g., maxillary molars have 3 roots, mandibular molars have 2).
- Developmental anomalies: fusion, gemination, dens invaginatus, enamel hypoplasia; may affect treatment planning.
Must Know
- Identify all permanent and primary teeth by name, number, and key features.
- Understand the chronology of tooth eruption (primary: ~6 months to 2.5 years; permanent: ~6 to 12 years).
- Describe the components of the periodontium: gingiva, periodontal ligament, cementum, alveolar bone.
- Explain the concept of centric occlusion vs. centric relation and their clinical significance.
Clinical and Exam Application
- Accurate tooth numbering is critical for charting, treatment planning, and insurance claims.
- Knowledge of root morphology aids in endodontic access and extraction planning.
- Occlusal analysis guides restorative and orthodontic treatment.
High-Yield Distinctions
- Maxillary first premolar: two roots (bifurcated) vs. maxillary second premolar: usually one root.
- Mandibular first molar: two roots (mesial and distal) with two canals in mesial root; second molar: often C-shaped root canal configuration.
- Primary molars: more bulbous crowns, thinner enamel, and roots that diverge more than permanent molars.
Common Pitfalls
- Confusing mandibular first and second premolars: first premolar has a prominent transverse ridge; second premolar has a more rounded occlusal table.
- Misidentifying tooth numbers when using different numbering systems.
- Overlooking the presence of supernumerary teeth (e.g., mesiodens) in radiographic interpretation.
Review Tasks
- Practice identifying teeth on extracted specimens or high-quality images.
- Create flashcards for tooth morphology and eruption dates.
- Review occlusion concepts using mounted study models.
Dental Radiography and Imaging
Syllabus Focus
- Radiographic techniques (intraoral, extraoral)
- Radiation physics and safety
- Image interpretation
- Advanced imaging (CBCT, MRI)
Key Notes
- Intraoral techniques: periapical (paralleling vs. bisecting angle), bitewing, occlusal. Paralleling technique minimizes distortion.
- ALARA principle: As Low As Reasonably Achievable. Use lead apron, thyroid collar, and fast film/digital sensors.
- Radiographic landmarks: lamina dura, periodontal ligament space, pulp chamber, root canals, alveolar crest.
- Common pathologies: caries (radiolucent), periapical abscess (radiolucent at apex), condensing osteitis (radiopaque).
- CBCT provides 3D imaging with lower radiation than medical CT; indicated for implant planning, impacted teeth, and pathology assessment.
Must Know
- Identify normal radiographic anatomy: maxillary sinus, nasal cavity, zygomatic arch, mandibular canal, mental foramen.
- Differentiate between radiolucent and radiopaque lesions and list common examples.
- Understand the effects of exposure factors (kVp, mA, time) on image density and contrast.
- Recognize errors in radiography: elongation, foreshortening, cone cut, overlapping.
Clinical and Exam Application
- Bitewings are used for interproximal caries detection; periapicals for periapical pathology and root morphology.
- Panoramic radiography is useful for impacted teeth, jaw fractures, and large lesions.
- CBCT is essential for 3D assessment of root canal anatomy, implant sites, and temporomandibular joint.
High-Yield Distinctions
- Radiolucent lesions: cyst (e.g., dentigerous), granuloma, abscess, tumor (e.g., ameloblastoma). Radiopaque lesions: condensing osteitis, osteoma, idiopathic osteosclerosis.
- Periapical radiolucency indicates pathology at root apex; normal lamina dura is continuous and radiopaque.
- Digital radiography: direct (CCD/CMOS) vs. indirect (PSP) sensors; PSP requires scanning.
Common Pitfalls
- Misinterpreting the mental foramen as a periapical lesion on mandibular premolars.
- Failing to use proper infection control for sensors (barrier envelopes).
- Overlooking patient radiation dose when ordering CBCT without justification.
Review Tasks
- Label radiographic anatomy on a panoramic film.
- Practice identifying caries and periodontal bone loss on bitewings.
- Review ALARA principles and state regulations for radiation safety.
Infection Control and Sterilization Protocols
Syllabus Focus
- Standard precautions
- Sterilization methods (autoclave, chemical, dry heat)
- Disinfection and antisepsis
- OSHA and CDC guidelines
Key Notes
- Standard precautions apply to all patients: hand hygiene, PPE (gloves, mask, eyewear, gown), safe injection practices.
- Sterilization kills all microorganisms; autoclaving (steam under pressure) is most common: 121°C for 30 min or 134°C for 15 min.
- Chemical sterilants (e.g., glutaraldehyde) require longer immersion (10+ hours) and are used for heat-sensitive instruments.
- Disinfection: intermediate-level (e.g., EPA-registered hospital disinfectant) for clinical surfaces; low-level for non-critical surfaces.
- OSHA requires exposure control plan, hepatitis B vaccination, and annual training. CDC guidelines detail infection control in dental settings.
Must Know
- Classify instruments as critical (enter sterile tissue), semi-critical (contact mucous membranes), non-critical (intact skin).
- Steps for instrument processing: cleaning, packaging, sterilization, storage.
- Spore testing (biological indicator) must be done weekly to verify autoclave efficacy.
- Hand hygiene: before and after patient contact, after glove removal, after touching contaminated surfaces.
Clinical and Exam Application
- Use of barriers (plastic covers) on light handles, x-ray units, and keyboards to prevent cross-contamination.
- Proper disposal of sharps in puncture-resistant containers.
- Management of needlestick injuries: immediate first aid, reporting, post-exposure prophylaxis.
High-Yield Distinctions
- Autoclave: steam sterilization; dry heat oven: higher temperature (160-170°C) for longer time; chemical vapor: for instruments that may rust.
- Glutaraldehyde is a high-level disinfectant/sterilant; requires proper ventilation and immersion time.
- Hand sanitizers (alcohol-based) are effective but not for visibly soiled hands.
Common Pitfalls
- Assuming all disinfectants are sterilants; only sterilants can achieve sterility.
- Improper packaging (e.g., overloading autoclave) leading to incomplete sterilization.
- Reusing single-use items (e.g., prophylaxis angles, needles) is prohibited.
Review Tasks
- Create a flowchart for instrument processing from patient use to storage.
- Review CDC guidelines for dental infection control (summary).
- Practice spore testing interpretation and record-keeping.
Chairside Assisting and Clinical Procedures
Syllabus Focus
- Four-handed dentistry
- Instrument transfer and ergonomics
- Procedure setup and patient management
- Common restorative and surgical procedures
Key Notes
- Four-handed dentistry: operator and assistant work together to maximize efficiency. Assistant's zone: transfer zone (4-8 o'clock relative to patient).
- Instrument transfer: use of pen grasp, palm grasp; transfer in the operator's field of vision without crossing the patient's face.
- Ergonomics: operator seated with thighs parallel to floor, back straight; assistant at eye level with operator.
- Common procedures: Class I-V restorations, crown preparation, scaling and root planing, extraction, endodontic access.
- Patient management: explain procedure, obtain consent, monitor vital signs, manage anxiety (e.g., nitrous oxide).
Must Know
- Identify and set up basic tray setups for: examination, restorative, surgical, endodontic, periodontal procedures.
- Understand the steps of a typical restorative procedure: anesthesia, isolation (rubber dam), cavity preparation, restoration placement, finishing.
- Know the roles of the assistant: retraction, suction, instrument transfer, material preparation.
- Recognize common dental materials used chairside: composite, amalgam, glass ionomer, impression materials.
Clinical and Exam Application
- Efficient instrument transfer reduces procedure time and operator fatigue.
- Proper isolation (rubber dam) improves visibility and moisture control for restorative and endodontic procedures.
- Suction tip placement: high-volume evacuator (HVE) for fluid control, saliva ejector for comfort.
High-Yield Distinctions
- HVE vs. saliva ejector: HVE removes large volumes and reduces aerosol; saliva ejector is for low-volume suction.
- Rubber dam clamp selection: winged vs. wingless; clamp size based on tooth type.
- Matrix band types: Tofflemire (universal), sectional (for Class II composites).
Common Pitfalls
- Incorrect instrument transfer (e.g., passing a scaler with the sharp end toward the operator).
- Failure to maintain aseptic technique during surgical procedures.
- Not anticipating the operator's next instrument, causing delays.
Review Tasks
- Practice instrument transfer with a partner using a typodont.
- Review tray setups for different procedures (e.g., extraction kit, crown prep kit).
- Study ergonomic principles and adjust your chair and patient position.
Dental Materials and Laboratory Procedures
Syllabus Focus
- Properties of dental materials
- Restorative materials (composite, amalgam, glass ionomer, ceramics)
- Impression materials and techniques
- Laboratory procedures (crown, bridge, denture fabrication)
Key Notes
- Dental materials must be biocompatible, durable, and esthetic. Key properties: compressive strength, tensile strength, modulus of elasticity, thermal expansion.
- Composite resin: polymer matrix with filler particles; light-cured; used for direct restorations. Bonding requires etch, prime, adhesive.
- Amalgam: alloy of mercury, silver, tin, copper; high compressive strength; requires mechanical retention (undercuts).
- Glass ionomer: releases fluoride; bonds chemically to tooth; used for restorations, liners, luting cement.
- Impression materials: alginate (irreversible hydrocolloid) for study models; polyvinyl siloxane (addition silicone) for final impressions.
Must Know
- Compare and contrast direct vs. indirect restorations: direct (composite, amalgam) placed in mouth; indirect (crown, inlay) fabricated in lab.
- Understand the setting reaction of alginate: irreversible hydrocolloid; gypsum products: dental stone, plaster.
- Know the steps for crown fabrication: tooth preparation, impression, temporary crown, lab fabrication, cementation.
- Identify common laboratory equipment: model trimmer, vibrator, casting machine, porcelain furnace.
Clinical and Exam Application
- Choice of restorative material depends on location, esthetics, caries risk, and occlusal forces.
- Impression technique: proper tray selection, adhesive application, mixing, and setting time.
- Cementation: luting agents (zinc phosphate, glass ionomer, resin cement) have different properties and indications.
High-Yield Distinctions
- Composite polymerization shrinkage: 2-3% volumetric; incremental placement reduces stress.
- Amalgam vs. composite: amalgam has higher wear resistance but poor esthetics; composite bonds to tooth but may have microleakage.
- Gypsum products: plaster (Type II) for study models; stone (Type III) for working casts; die stone (Type IV) for dies.
Common Pitfalls
- Inadequate moisture control during composite placement leading to bond failure.
- Over-trimming a die or model, causing inaccurate restoration fit.
- Using expired impression materials or improper mixing ratios.
Review Tasks
- Create a comparison chart of restorative materials (indications, advantages, disadvantages).
- Practice mixing alginate and pouring a study model.
- Review the steps of a crown and bridge procedure from preparation to cementation.
Medical Emergencies and Pharmacology
Syllabus Focus
- Common medical emergencies in dental practice
- Emergency drugs and equipment
- Pharmacology: local anesthetics, analgesics, antibiotics, sedatives
- Patient medical history and risk assessment
Key Notes
- Common emergencies: syncope (most common), allergic reaction, hypoglycemia, seizures, cardiac arrest, airway obstruction.
- Emergency kit: oxygen, epinephrine (EpiPen), antihistamine (diphenhydramine), bronchodilator (albuterol), nitroglycerin, glucose, aspirin, naloxone.
- Local anesthetics: amides (lidocaine, articaine) vs. esters (procaine); amides are more common due to lower allergenicity. Maximum doses: lidocaine 4.4 mg/kg (with epinephrine 7 mg/kg).
- Analgesics: NSAIDs (ibuprofen, naproxen) for mild-moderate pain; opioids (codeine, hydrocodone) for severe pain; acetaminophen for mild pain or when NSAIDs contraindicated.
- Antibiotics: amoxicillin (first-line for odontogenic infections), clindamycin (for penicillin allergy), metronidazole (for anaerobic infections).
Must Know
- Recognize signs and symptoms of syncope: pallor, sweating, dizziness, loss of consciousness; treatment: Trendelenburg position, oxygen, ammonia inhalant.
- For anaphylaxis: immediate epinephrine IM (0.3 mg adult), call 911, oxygen, antihistamine.
- Understand drug interactions: epinephrine with MAOIs or beta-blockers may cause hypertensive crisis or reduced efficacy.
- Review medical history for contraindications: anticoagulants (bleeding risk), bisphosphonates (osteonecrosis risk), pregnancy (avoid certain drugs).
Clinical and Exam Application
- Preoperative assessment: vital signs, ASA classification, medication list, allergies.
- Use of vasoconstrictors in local anesthetics: epinephrine prolongs anesthesia and reduces bleeding; contraindicated in severe cardiovascular disease.
- Prescribing antibiotics: only for infections with systemic signs (fever, swelling); not for routine prophylaxis except in specific cardiac conditions.
High-Yield Distinctions
- Lidocaine vs. articaine: articaine has higher lipid solubility and better bone penetration; max dose 7 mg/kg (with epinephrine).
- Epinephrine concentration: 1:100,000 (0.01 mg/mL) vs. 1:200,000 (0.005 mg/mL); lower concentration for cardiac patients.
- Benzodiazepines (diazepam, midazolam) for sedation; flumazenil is reversal agent.
Common Pitfalls
- Administering epinephrine to a patient with unstable angina or recent MI.
- Overlooking drug allergies (e.g., penicillin allergy) when prescribing antibiotics.
- Failing to monitor vital signs during sedation or in medically compromised patients.
Review Tasks
- Memorize the contents of a dental emergency kit and their indications.
- Practice calculating maximum doses of local anesthetics for different patient weights.
- Review common drug interactions and contraindications using a pharmacology reference.
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.
