  1. Which Angle's classification describes a malocclusion where the mesiobuccal cusp of the upper first molar occludes anterior to the buccal groove of the lower first molar?

    Answer: Class II

    Angle Class II malocclusion is defined by a distal relationship of the mandible, where the maxillary first molar is ahead (mesial) of its ideal position relative to the mandibular first molar.

  2. Which tooth structure is formed last during tooth development?

    Answer: Cementum

    Cementum is deposited by cementoblasts after root formation begins, which occurs after enamel and dentin have already been laid down by ameloblasts and odontoblasts.

  3. What does the acronym 'BRONJ' refer to in dental practice?

    Answer: Bisphosphonate-Related Osteonecrosis of the Jaw

    BRONJ (now termed MRONJ—Medication-Related Osteonecrosis of the Jaw) is exposed necrotic bone in patients taking bisphosphonates or antiresorptive agents.

  4. Which primary (deciduous) teeth are the last to erupt in the oral cavity?

    Answer: Maxillary second molars

    The maxillary second primary molars are typically the last deciduous teeth to erupt, around 24–33 months of age, completing the primary dentition of 20 teeth.

  5. What is the scientific name of the primary pathogen responsible for early childhood caries (ECC)?

    Answer: Streptococcus mutans

    Streptococcus mutans is the principal bacterium responsible for early childhood caries due to its ability to produce lactic acid and adhere to tooth surfaces via glucans.

  6. Which anatomical landmark on the hard palate is used as a reference point in prosthodontic impressions?

    Answer: Fovea palatinae

    The fovea palatinae are two small pits at the junction of the hard and soft palate and serve as a reliable landmark for establishing the posterior border of a complete maxillary denture.

  7. Which dental material contains bisphenol A-glycidyl methacrylate (Bis-GMA) as its primary resin matrix?

    Answer: Composite resin

    Composite resin restorative materials are based on Bis-GMA (bisphenol A-glycidyl methacrylate) monomer cross-linked with TEGDMA, providing tooth-colored esthetic restorations.
