Dental Anatomy flashcards for NEET MDS

21 of 51 cards from the Dental Anatomy deck — real questions with worked answers.

1. What is the definition of Dental Anatomy?

   Dental Anatomy is the branch of dental science dealing with the development, morphology, function, and identification of the teeth and their relationship to one another and to the supporting structures.

2. What is the difference between the clinical crown and the anatomical crown of a tooth?

   The anatomical crown is the part covered by enamel (constant). The clinical crown is the part visible in the mouth above the gingiva, which changes with gingival recession or eruption.

3. In dental nomenclature, what do the surface terms 'mesial' and 'distal' mean?

   Mesial is the proximal surface nearest to the midline of the dental arch; distal is the proximal surface farthest from the midline.

4. What do the terms 'labial', 'buccal', and 'lingual/palatal' designate on a tooth?

   Labial = surface facing the lips (anteriors); buccal = surface facing the cheek (posteriors); lingual = surface facing the tongue (palatal in the maxilla).

5. What is the FDI two-digit tooth numbering for the maxillary right permanent central incisor?

   11 (first digit '1' = maxillary right quadrant; second digit '1' = central incisor).

6. In the FDI system, what quadrant digits are assigned to permanent teeth and to primary teeth?

   Permanent quadrants are 1-4 (UR, UL, LL, LR); primary quadrants are 5-8 (UR, UL, LL, LR).

7. From which germ layers and structures do the dental tissues develop?

   Enamel develops from ectoderm (dental lamina/enamel organ); dentin, pulp, and cementum develop from ectomesenchyme (neural crest-derived dental papilla and dental follicle).

8. List the morphological stages of tooth development (odontogenesis) in order.

   Initiation (dental lamina) → bud stage → cap stage → bell stage → apposition → maturation.

9. What is the function of Hertwig's epithelial root sheath (HERS)?

   HERS determines the shape and number of roots and induces differentiation of root dentin; its remnants form the epithelial rests of Malassez.

10. What is the role of the enamel knot during tooth development?

    The enamel knot is a signaling center in the cap stage that controls cusp formation and crown morphogenesis through expression of signaling molecules (e.g., Shh, FGF, BMP).

11. How many teeth are present in the permanent and the deciduous dentition?

    Permanent dentition = 32 teeth (2-1-2-3 per quadrant); deciduous dentition = 20 teeth (2-1-0-2 per quadrant).

12. What is the dental formula of the permanent human dentition?

    I 2/2, C 1/1, PM 2/2, M 3/3 (per side) — total 32 teeth.

13. What is the dental formula of the deciduous (primary) human dentition?

    I 2/2, C 1/1, M 2/2 (per side) — total 20 teeth; there are no premolars in the primary dentition.

14. Which permanent tooth is usually the first to erupt, and at what approximate age?

    The mandibular first molar, at approximately 6 years of age (hence 'six-year molar').

15. What is the usual eruption sequence of the primary teeth?

    Central incisors → lateral incisors → first molars → canines → second molars (approximately 6-30 months).

16. List four ways deciduous teeth differ morphologically from permanent teeth.

    Deciduous teeth are smaller and whiter, have a more bulbous crown with a prominent cervical ridge, thinner enamel/dentin, larger pulp chambers and prominent pulp horns, and more divergent/flared roots.

17. In comparative dental anatomy, what does a 'brachydont' tooth mean and give an example?

    A brachydont (low-crowned) tooth has a short crown and well-developed roots, e.g., human teeth and carnivore teeth, as opposed to hypsodont (high-crowned) teeth like those of horses.

18. What is meant by a 'heterodont' versus a 'homodont' dentition?

    Heterodont = teeth of different morphological types (incisors, canines, premolars, molars), as in humans; homodont = all teeth of similar form, as in many fish and reptiles.

19. Define 'diphyodont' dentition.

    Diphyodont means having two successive sets of teeth in a lifetime — the deciduous (primary) and the permanent dentitions; humans are diphyodont.

20. What is the cusp of Carabelli, and where is it found?

    The cusp of Carabelli is a non-functional accessory (fifth) cusp located on the mesiolingual surface of the maxillary first permanent molar.

21. What are mamelons and on which teeth are they seen?

    Mamelons are three rounded projections on the incisal edge of newly erupted permanent incisors; they represent the developmental lobes and wear away with use.
