  1. A patient presents with a deep periodontal pocket, vertical bone loss, and a positive furcation involvement on a mandibular molar. Which classification best describes a furcation defect that can be probed through but is not visible clinically?

    Answer: Glickman Grade III

    Glickman Grade III is a through-and-through furcation that can be probed completely but remains covered by soft tissue and is not clinically visible.

  2. Which local anesthetic is contraindicated in patients with a documented allergy to para-aminobenzoic acid (PABA)?

    Answer: Benzocaine

    Benzocaine is an ester anesthetic metabolized to PABA, making it contraindicated in PABA-allergic patients, unlike the amide anesthetics.

  3. A radiograph shows a well-defined radiolucency at the apex of a non-vital tooth that has been asymptomatic for years. Which lesion is most likely?

    Answer: Periapical cyst

    A long-standing, asymptomatic, well-defined periapical radiolucency associated with a non-vital tooth is most consistent with a periapical (radicular) cyst.

  4. In endodontics, which irrigant is primarily used to remove the smear layer's inorganic component?

    Answer: EDTA

    EDTA is a chelating agent that dissolves the inorganic mineral portion of the smear layer, while sodium hypochlorite dissolves organic tissue.

  5. Which restorative material chemically bonds to tooth structure and releases fluoride, making it useful for high-caries-risk patients?

    Answer: Glass ionomer cement

    Glass ionomer cement chemically bonds to enamel and dentin and releases fluoride, offering anticariogenic benefit.

  6. A patient on long-term oral bisphosphonate therapy needs an extraction. What is the most serious associated complication to counsel them about?

    Answer: Medication-related osteonecrosis of the jaw

    Bisphosphonates are associated with medication-related osteonecrosis of the jaw (MRONJ), a risk after invasive dental procedures.

  7. Which cranial nerve provides general sensory innervation to the anterior two-thirds of the tongue?

    Answer: Lingual branch of trigeminal (V3)

    The lingual nerve, a branch of the mandibular division of the trigeminal (V3), carries general sensation from the anterior two-thirds of the tongue.
