ORAL PATHOLOGY COMPLETE EXAM QUESTIONS AND
100% VERIFIED ANSWERS (PASS GUARANTEE)
1. What is anodontia? Complete absence of teeth, can be total (all teeth) or
partial (some teeth missing).
2. What causes amelogenesis imperfecta? A hereditary condition affecting
enamel formation due to genetic mutations in enamel matrix proteins.
3. Define taurodontism. An anomaly where the pulp chamber is enlarged and
extends apically, with shortened roots.
4. What is dentinogenesis imperfecta? A hereditary disorder affecting dentin
formation, resulting in discolored, weak teeth that wear easily.
5. What is dens invaginatus? A developmental anomaly where enamel
invaginates into the tooth, creating a "tooth within a tooth."
6. What is dens evaginatus? An extra cusp projecting from the occlusal
surface, common on premolars in Asian populations.
7. What causes dilaceration? Trauma during tooth development that causes
abnormal angulation or curvature of the root.
8. What is gemination? A single tooth bud attempts to divide, resulting in a
tooth with one root and one pulp chamber but appears double.
9. What is fusion of teeth? Two separate tooth buds unite during development,
sharing dentin but may have separate pulp chambers.
10. What is concrescence? Union of two teeth by cementum only, typically
occurring after development is complete.
,11. What is macrodontia? Abnormally large teeth, can affect single or
multiple teeth.
12. What is microdontia? Abnormally small teeth, commonly seen in
maxillary lateral incisors and third molars.
13. What is hyperdontia? Presence of supernumerary teeth beyond the normal
dental formula.
14. What is a mesiodens? A supernumerary tooth located between the
maxillary central incisors.
15. What causes enamel hypoplasia? Deficient enamel formation due to
systemic factors during development like fever, malnutrition, or trauma.
16. What are enamel pearls? Small nodules of enamel found on root surfaces,
usually at furcation areas.
17. What is regional odontodysplasia? A developmental anomaly affecting
both enamel and dentin, producing "ghost teeth" on radiographs.
18. What is hypercementosis? Excessive cementum deposition on root
surfaces, appearing as bulbous roots radiographically.
19. What is a talon cusp? An extra cusp on the lingual surface of anterior teeth
resembling an eagle's talon.
20. What causes tooth transposition? A developmental anomaly where two
adjacent teeth exchange positions in the arch.
21. What is enamel hypomineralization? Defective mineralization of enamel
matrix resulting in discolored, porous enamel.
22. What is molar-incisor hypomineralization? A specific pattern affecting
first permanent molars and incisors with demarcated opacities.
23. What is Turner's tooth? Localized enamel hypoplasia of a permanent
tooth due to infection or trauma to its deciduous predecessor.
24. What are natal teeth? Teeth present at birth, usually mandibular incisors.
25. What are neonatal teeth? Teeth that erupt within the first 30 days of life.
26. What is oligodontia? Congenital absence of six or more teeth, excluding
third molars.
, 27. What is a paramolar? A supernumerary tooth located buccally or lingually
to a molar.
28. What causes environmental enamel hypoplasia? Systemic disturbances
during amelogenesis such as infections, nutritional deficiencies, or metabolic
disorders.
29. What is hereditary enamel hypoplasia? Genetically determined defective
enamel formation affecting primary and permanent dentitions.
30. What is a distomolar? A supernumerary tooth distal to the third molar.
Section 2: Caries and Pulpal Pathology (Questions 31-60)
31. What is dental caries? A bacterial disease causing localized destruction of
tooth hard tissues through acid demineralization.
32. What bacteria primarily causes dental caries? Streptococcus mutans is
the primary causative organism.
33. What is rampant caries? Sudden onset of widespread caries affecting
multiple teeth, including those normally resistant to decay.
34. What is nursing bottle caries? Severe early childhood caries caused by
prolonged exposure to sugary liquids in bottles.
35. What is root caries? Caries affecting exposed root surfaces in patients with
gingival recession.
36. What is arrested caries? Carious lesions that have stopped progressing and
become remineralized and hardened.
37. What is recurrent caries? Caries occurring at the margins of existing
restorations.
38. What is reversible pulpitis? Mild pulpal inflammation that can return to
normal if the irritant is removed.
39. What is irreversible pulpitis? Severe pulpal inflammation that cannot heal
and requires endodontic treatment.
40. What is pulp necrosis? Death of the dental pulp due to untreated pulpitis or
trauma.
