21
Q

Multiocular

A

Radiographic appearance in which many circular radiolucencies exist; can look like a soap bubble or honey comb

22
Q

Nodule

A

Small solid mass that can be detected through touch

23
Q

Oligodontia

A

Subcategory of hypodontia in which 6 or more teeth are missing

24
Q

Predilection

A

Disposition in favor of something “preference”

25
Q

Proliferation

A

Multiplication of cells

26
Q

stomodeum

A

Embryonic invagination that becomes the oral cavity

27
Q

Supernumerary

A

Excess of the normal or regular number as in teeth
Formation of extra tooth buds in the dental lamina or the splitting of already existing buds
May be in primary or permanent
Most often in the maxilla
Smaller than the other teeth may not erupt

28
Q

Mesiodens

A

Most common supernumerary
Located between maxillary incisors
Maybe inverted when seen in radiographs

29
Q

Distomolar

A

Second most common supernumerary tooth
Located distal to the 3rd molar

30
Q

Multiple supernumerary teeth may be associated with

A

Cleidocranial dysplasia or Gardner syndrome

31
Q

True generalized microdontia

A

Seen in dwarf; all teeth are smaller than normal

32
Q

Generalized relative microdontia

A

normal sized teeth appear small in a large jaw
Seen in gigantism

33
Q

Abnormalities in the shape of teeth

A

-Germination
-fusion
-concrescence
-dilaceration
-Enamel pearl
-talon cusp
-taurodontism
-dens in dente
-Dens evaginatus
-Supernumerary roots

34
Q

Gemination

A

Single tooth attempts to divide in 2
Most common deciduous tooth
-Primary mandibular incisor
Most common permanent tooth
-Maxillary incisors
Looks like 2 crowns joined by a notch in the incisal area
Pt still has the correct amount of teeth

35
Q

Fusion

A

2 normally separated adjacent tooth germs
Most common in the anterior region (incisors)
Single large crown
Pt is usually missing 1 tooth

36
Q

Hypercementosis

A

Excessive cementum on the roots of teeth
-happens in adults increases the amount with age
- associated with many local and systemic factors
- no treatment necessary

37
Q

Enamel pearl

A
  • Small, spherical enamel projection on the root surface
    -maxillary molars
    -removal maybe necessary for perio problems
    -clinical; maybe mistaken for calculus
  • uncommon
38
Q

Talon cusp

A

Cingulum area of maxillary or mandibular permanent incisor
- Made of enamel and dentin; contains the pulp horn
- May interfere with occlusion
-Treatment; remove if occlusion interfere

39
Q

Taurodontism

A

Elongated pulp chambers and short roots
- in deciduous and permanent
-no treatment

40
Q

Dens evaginatus

A

Accessory enamel cusp on the occlusal of tooth surface
- most common on mandibular premolar’s
-caused by he proliferation and out pouching of the enamel
-pulp horn may be in the enamel cusp

41
Q

Supernumerary roots

A

Any tooth
-Most common single rooted teeth; Mandibular bicuspid and cuspids
-Mast common multi rooted teeth; maxillary and mandibular 3rd molars

42
Q

Abnormalities tooth structure

A
  • enamel hypoplasia
    -Enamel hypocalcification
  • endogenous staining of the teeth
    -Regional ondontodysplasia
43
Q

Factors that cause enamel hypoplasia

A

-Amelogenesis imperfecta
Febrile illness (measles, chickenpox, scarlet fever)
Vitamin deficiency
Infection of a deciduous tooth
Ingestion of fluoride
Congenital syphilis
Birth injury, premature birth
Idiopathic factors

44
Q

When does enamel hypoplasia occur?

A

During enamel matrix formation when there is damage to the ameloblasts

45
Q

Enamel hypoplasia caused by febrile illness or vitamin deficiency

A
  • only happens to the teeth forming at the time of injury
46
Q

Enamel hypoplasia resulting from local infection or trauma

A

-if it’s a single tooth its a turner tooth
- color will range from yellow to brown or severe pitting deformity can occur

47
Q

Enamel hypoplasia resulting from fluoride ingestion

A
  • mottled discoloration of enamel
  • 2-3 time the amount of fluoride leads to white flecks and chalky opaque areas of enamel
    -4X’s causes black or brown staining
48
Q

Enamel hypocalcification

A

-worst because enamel is soft
- A chalky white spot on the middle 1/3 of smooth crowns

49
Q

Endogenous staining of teeth

A

Result of deposition of substance during tooth development
-Tetracycline stain
-Erythroblastosis fetalis: Rh incompatibility
-neonatal liver disease
-congenital porphyria: inherited metabolic disease

50
Q

Regional odontodysplasia (ghost teeth)

A

-Very thin enamel and dentin present
- treatment; extraction

51
Q

Abnormalities of tooth eruption

A

Impacted teeth- obstruction
Embedded teeth- lack of eruptive force
-between 12-24 years

52
Q

Ankylosed teeth

A

-Deciduous molars are most common
-teeth cementum fused to bone
-prevents exfoliation of deciduous tooth and of eruption of underlying adult tooth
-difficult to extract
