DENTISTRY EXAM 2025/2026
QUESTIONS AND ANSWERS 100% PASS.
Crown - ANS The ____ is normally covered by enamel and meets the root at an important
landmark called the cemento-enamel junction (CEJ). The CEJ is anatomically the neck of the
tooth and is not normally visible.
roots - ANS Teeth may have one or more ____. In those teeth with two or more, the point
where they diverge is called the furcation angle. This can be a bifurcation or a trifurcation.
alveolar bone - ANS The roots are encased in the alveolar processes of the jaws. The process
comprises _____ ___, trabecular bone and compact bone.
lamina dura - ANS Sight of an uninterrupted ____ ___ is interpreted radiographically as a sign
of good periodontal health.
enamel - ANS ____ is 96% inorganic, mainly hydroxyapatite crystals, with 4% water and
fibrous organic material. It is the hardest substance in the body and covers the exterior surface
of the crowns only.
dentine - ANS _____ is the main supporting structure of the tooth and is the second hardest
tissue in the body after enamel. The main structure is the dentinal tubule, which extends from
the external surface to the pulp.
primary - ANS Which type of dentine is described below?

, (primary, secondary, or tertiary)
Forms before tooth eruption.
secondary - ANS Which type of dentine is described below?
(primary, secondary, or tertiary)
Forms after eruption, as the tooth develops with age. It develops from the ondontoblasts living
within the pulp and is laid down in layers within the pulp cavity.
tertiary - ANS Which type of dentine is described below?
(primary, secondary, or tertiary)
Forms as a result of trauma to the ondontoblasts; this can be theraml, chemical, bacterial, or
mechanical. Has few tubules and is darker in color and very dense in structure.
cementum - ANS _____ covers the enamel free roots and provides a point of attachment for
the periodontal ligament. It is capable of formation, destruction and repair and remodels
continually throughout life. It is nourished from vessels within the periodontal ligament.
periodontal ligament - ANS The _____ ____ is comprised of taut collagen fibre bundles
(called Sharpey's fibres where they are inserted in cementum and alveolar bone) which are
anchored to the cementum of the tooth and the alveolar bone.
periodontal ligament - ANS Which tooth structure has evenly distributed blood vessels and
nerves capable of transmitting heat, cold, pain, and pressure in addition to proprioception in
some species?
pulp - ANS This living tissue within the tooth is located in the pulp chambers and root canals.
It is well innervated and vascularised and comprises connective tissue, nerves, lymph and blood
vessels, collagen and undifferentiated reserve mesenchymal cells (e.g. odontoblasts).
