Understanding the Maryland Licensure Requirements
To practice dentistry in Maryland, you must first pass the INBDE (the national clinical and written exam)
and then the Maryland Dental Jurisprudence Exam, which tests your knowledge of state-specific laws
and ethical guidelines. You must be at least 18 years of age, hold a D.D.S. or D.M.D. degree from a
CODA-accredited dental school, and submit an official transcript and application to the Maryland State
Board of Dental Examiners.
A key component is the Maryland Dental Jurisprudence Examination. This test covers laws, regulations,
and ethics as defined by the Board. A score of 75 or higher is required to pass.
INBDE-Style Practice Questions & Rationales
The following questions are modeled on the Integrated National Board Dental Examination blueprint.
Each question is followed by a verified answer and a detailed rationale to help you build clinical
reasoning skills.
Q1. Which type of radiograph is ideal for detecting periapical lesions?
• A. Bitewing
• B. Periapical
• C. Panoramic
• D. Occlusal
✅ Answer: B. Periapical
Rationale: Periapical radiographs provide a detailed, high-resolution view of the entire tooth root and
the surrounding alveolar bone, making them the gold standard for detecting apical pathology. Bitewings
are used for interproximal caries, panoramic for overall evaluation, and occlusal for large areas of the
anterior maxilla or mandible.
Q2. Which bacteria is most commonly associated with dental caries?
,2
• A. Streptococcus mutans
• B. Porphyromonas gingivalis
• C. Lactobacillus acidophilus
• D. Actinomyces israelii
✅ Answer: A. Streptococcus mutans
Rationale: S. mutans is the primary cariogenic bacterium because of its ability to metabolize dietary
sugars into organic acids, leading to enamel demineralization. P. gingivalis is linked to periodontitis, L.
acidophilus contributes to progression but not initiation, and A. israelii is associated with actinomycosis.
Q3. Which local anesthetic provides the longest duration of pulpal anesthesia?
• A. Bupivacaine
• B. Lidocaine
• C. Articaine
• D. Mepivacaine
✅ Answer: A. Bupivacaine
Rationale: Bupivacaine is a long-acting amide anesthetic that provides pulpal anesthesia lasting 2–4
times longer than lidocaine, making it ideal for extended procedures. Lidocaine and mepivacaine are
intermediate-acting, while articaine offers moderate duration.
Q4. A 25-year-old patient presents with a deep carious lesion on tooth #30. The patient reports
occasional pain to cold and sweets. Pulp tests are normal. What is the most appropriate treatment?
• A. Extraction
• B. Root canal therapy
• C. Indirect pulp capping
• D. Direct pulp capping
✅ Answer: C. Indirect pulp capping
Rationale: Because the pulp is vital and responds normally, indirect pulp capping is indicated. This
technique preserves pulpal vitality by carefully removing infected dentin while leaving a thin layer of
affected dentin over the pulp, followed by placement of a biocompatible material.
Q5. Which cranial nerve is responsible for motor innervation of the muscles of mastication?
,3
• A. CN V₁ (ophthalmic)
• B. CN V₂ (maxillary)
• C. CN V₃ (mandibular)
• D. CN VII (facial)
✅ Answer: C. CN V₃ (mandibular)
Rationale: The mandibular branch of the trigeminal nerve (CN V₃) provides motor fibers to the masseter,
temporalis, medial pterygoid, and lateral pterygoid muscles, as well as sensory innervation to the lower
face and anterior two-thirds of the tongue.
Q6. Which instrument is primarily used for subgingival scaling?
• A. Curette
• B. Scaler
• C. Explorer
• D. Periodontal probe
✅ Answer: A. Curette
Rationale: Curettes (e.g., Gracey or Columbia) have a rounded back and a sharp cutting edge, allowing
them to be inserted into periodontal pockets for effective subgingival scaling and root planing without
damaging the gingiva.
Q7. Which radiographic feature is most indicative of chronic apical periodontitis?
• A. Widened PDL space
• B. Radiolucent periapical lesion with sclerotic border
• C. Internal root resorption
• D. Hypercementosis
✅ Answer: B. Radiolucent periapical lesion with sclerotic border
Rationale: Chronic apical periodontitis is a long-standing inflammatory reaction to pulpal necrosis.
Radiographically, it appears as a well-defined radiolucent area at the root apex, often surrounded by a
sclerotic (radiopaque) border due to reactive bone formation.
Q8. Which of the following is NOT an element essential to valid informed consent in dentistry?
• A. Disclosure of treatment risks
, 4
• B. Patient’s voluntary signature
• C. Explanation of the dentist’s financial policies
• D. Explanation of alternative treatments
✅ Answer: C. Explanation of the dentist’s financial policies
Rationale: Valid informed consent requires disclosure of the diagnosis, nature and purpose of the
proposed treatment, material risks and benefits, and reasonable alternatives. Financial policies, while
important for the practice, are not a legal element of informed consent.
Maryland Dental Jurisprudence Exam Practice Questions
This section covers the state-specific laws, ethics, and regulations tested on the Maryland Dental
Jurisprudence Exam. A score of 75 is required to pass.
Q9. According to the ADA Principles of Ethics and Code of Professional Conduct, which principle best
describes the obligation to act in the best interest of the patient?
• A. Autonomy
• B. Beneficence
• C. Nonmaleficence
• D. Justice
✅ Answer: B. Beneficence
Rationale: Beneficence is the principle that requires a dentist to actively promote the patient’s welfare
and well-being, going beyond simply avoiding harm. It is the ethical foundation of patient-centered care.
Q10. A dentist learns that a colleague is providing treatment while impaired by alcohol but does not
report it. Which ethical principle is most directly violated?
• A. Justice
• B. Nonmaleficence
• C. Autonomy
• D. Fidelity
✅ Answer: B. Nonmaleficence
Rationale: Nonmaleficence – “do no harm” – is breached when a practitioner who may harm patients
remains unreported. Failing to report an impaired colleague violates the duty to protect patients from
potential injury.
