1. Amelogenesis imperfecta
developmental disturbance that causes abnormal
enamel formation
Teeth can appear yellow-brown or opaque white
Three broad phenotypes: hypoplastic, hypomatura-
tion, hypocalcified
2. unusual amount or appearance of enamel (wrinkly or Amelogenesis imperfecta
smooth), but normal enamel hardness (hypoplastic type)
3. defect in the maturation of enamel crystalline struc- Amelogenesis imperfecta
ture, resulting in softer than normal enamel that is (hypomaturation type)
mottled or opaque
4. defect in the mineralization of enamel, resulting in Amelogenesis imperfecta
softer enamel that is lost by attrition or abrasion (hypocalcified type)
5. dentinogenesis imperfecta
developmental disturbance that causes abnormal
dentin formation
teeth can appear discolored (blue-gray or yel-
low-brown), translucent, highly worn, and easily frac-
tured
crowns appear bulbous with cervical constriction and
obliterated pulp chamber
6. osteogenesis imperfecta (brittle bones and blue scle- Dentinogenesis Type I
ra) with opalescent teeth

7. Most common Dentinogenesis Type II
affects only dentin with no systemic effects
8. VERY rare Dentinogenesis type III
brandywine type
9. Type I dentin dysplasia
(radicular): short roots, or "rootless teeth", obliterated
pulp chamber or chevron-shaped remnant
affects primrary and permanent dentitions
10. Developmental disturbance that causes abnormal Dentin Dysplasia
dentin and pulpal morphology
types I and II
11. Type II dentin dysplasia
(coronal): normal roots, enlarged or thistle
tube-shaped pulp chambers, pulp stones, primary
dentition may appear discolored with obliterated pulp
12. regional odontodysplasia
non-hereditary abnormality of dental hard tissues in a
localized region or quadrant
poor mineralization of dentin and enamel ("ghost
teeth")

short roots, open apices, and enlarged pulp chmabers
13. congenital syphilis (hutchinson's incisor, mulberry mo-
lar)
Hutchinson's incisor: "screwdriver-shaped" or triangu-
lar incisor
Mulberry molar: first molars that appear like a mul-
berry fruit with extra and rounded enamel cusps
occurs when a pregnant mother transmits syphilis to
her child in utero or at birth
14. concrescence
union of adjacent teeth at the level of cementum
enamel, dentin, and pul are not involved
occurs most frequently in mx molars
15. Gemination
Attempt of one tooth bud to become two separate
teeth
NORMAL NUMBER of teeth
single root and pulp chamber
occurs most frequently in incisors
16.
