● Structures appears light or white in a
radiographic image
● Hard calcified structure
● Calcified does not let the radiation pass thru,
thus nag bobounce off ang radiation. That is
why it is color white

Q

● Eg. Her tooth might be smaller than hers, that
doesn’t mean she has microdontia. You have
to check in general the dentition and family
(genetic factor).

Q

TRUE GENERALIZED MICRODONTIA

A

● You have to check the jaw of the px; if the jaw
is normal in size.
● Normal jaw that houses small teeth.
● Nagkakaspace sa jaw na yun bcoz jaw develop
for normal size teeth. Pero dhil maliit teeth,
may spaces kahit complete teeth ng px.

Q

● Other teeth which are often congenitally absent, the
maxillary and mandibular second premolars, seldom
exhibit microdontia.
● Supernumerary teeth; however, a frequently small in
size
● Affects the maxillary lateral incisor, a condition that
has been called the ‘peg lateral’ .

Q

● more common
● presence of normal or slightly larger than normal
teeth in small jaws
● The disparity in size gives the illusion of macrodontia.

be considered.

have veneers or composite restorations for it
to look normal

CROWDING

19
Q

Relatively uncommon

the union of two or more teeth
results in a single large tooth.

hemihypertrophy of
the face,

A

MACRODONTIA OF SINGLE TEETH

20
Q

● Congenital absence of the teeth ; no tooth bud
thus no tooth will be formed

A

TRUE ANODONTIA

20
Q

● BStage 0-10, makikita sa radiograph kung
anong stage ng teeth magdedevelop.
● Tooth bud indicates if may tumutubong teeth

A

NOLLA’S STAGES OF TOOTH DEVELOPMENT

Q

TRUE ANODONTIA
may be 2 types:

A
  1. Total
  2. Partial
21
Q

● All teeth are missing, may involved both
deciduous and permanent dentition
● Rare condition

A

TOTAL ANODONTIA

22
Q

“retained deciduous tooth”.

Why is a retained deciduous tooth an
indication of either anodontia/ impaction?

A

TOTAL ANODONTIA

22
Q

Involves one or more teeth

any tooth may be congenitally
missing, there is a tendency for certain teeth to
be missing more frequently than others

A

HYPODONTIA / OLIGODONTIA

23
Q

● Are UNCOMMON but, when occurring,
● Usually involved maxillary lateral incisor
● Mandibular lateral incisor and Mandibular
cuspids may also be missing

A

CONGENITALLY MISSING DECIDUOUS TEETH

24
Q

● May closely resemble of the teeth of the group to
which it belongs,
● i.e. molars, premolars or anterior teeth, or it may be a
little resemblance in size or shape to the teeth with
which it is associated

A

SUPERNUMERARY TEETH

25
Q

e rare in individuals
with no other associated diseases or syndromes.

A

Multiple supernumerary teeth

25
Q

How do you know if it is a supernumerary tooth?

A

Count the number of teeth present. If ang px
is gnitong age, you know ilang teeth dpt mrn.

26
Q

4 DIFFERENT MORPHOLOGICAL TYPE OF
SUPERNUMERARY TEETH that have been described as:

A

○ Conical
○ Tuberculate
○ Supplemental
○ Odontome

27
Q

● This small peg shape conical tooth is supernumerary
● Most commonly found in the permanent dentition
● Develops with root formation ahead of or as an
equivalent stage to that of permanent incisors and
usually presents as a mesiodens

A

CONICAL TOOTH

28
Q

Found on the midline between the central
incisors.

A

MESIODENS

29
Q

Supernumerary tooth na molar. If it is there in the molar area.

A

PARAMOLAR

30
Q

Have more than 1 cusp or tubercle

A

TUBERCULATE

31
Q

● Tooth within a tooth
● Extra tooth formed within the tooth.
● It is frequently described as barrel-shaped and
may be invaginated.
● Root formation is delayed compared to that of the
permanent incisors.
● Are often paired
● commonly located on the palatal aspect of the central
incisors.
● They rarely erupt and are frequently associated with
delayed eruption of the incisors.

A

DENS IN DENTE

32
Q

● Refers to duplication of teeth in normal series and is
found at the end of a tooth series
● The most common supplemental tooth: permanent
maxillary lateral incisor,
● but supplemental premolars and molars also occur.
● The majority of supernumeraries found in the primary
dentition are of the supplemental type
● seldom remain impacted.

A

SUPPLEMENTAL

33
Q

● By Howard, not universally accepted
● The term ‘odontoma’ refers to any tumor of
odontogenic origin.

A

ODONTOME

34
Q
A
34
Q
A
35
Q

● May be composed of bone; enamel, dentin,
pulp (sometimes); periodontal ligament, PL
space (sa xray)

A

ODONTOMA

36
Q

● Mass. Naipon na cellular structure

A

TUMOR

37
Q

The lesion is composed of more than one type of tissue
and consequently has been called

A

composite
odontoma.

38
Q

● The diffuse mass of dental tissue which is totally
DISORGANIZED.

A

COMPLEX COMPOSITE ODONTOMA

39
Q

TWO TYPES OF ODONTOMA

A

COMPLEX COMPOSITE ODONTOMA

COMPOUND COMPOSITE ODONTOMA

40
Q

● The malformation which bears some superficial
anatomical similarity to a normal tooth

A

COMPOUND COMPOSITE ODONTOMA

41
Q

● Are individual teeth which are unerupted usually
because of a lack of eruptive force.

A

EMBEDDED TEETH

42
Q

● Impacted teeth are those presented from erupting by
some physical barrier in the eruption path

A

IMPACTED TEETH

43
Q

COMMON ETIOLOGIC FACTORS:

A

Lack of Space
Premature loss of deciduous teeth
Rotation of tooth buds

44
Q

Most frequent impacted:

A

○ Maxillary and Mandibular 3rd Molars
○ Maxillary cuspids
○ Followed by the premolar and
Supernumerary teeth

45
Q

are
more apt to exhibit severe impaction than the
maxillary teeth

Why?

A

mandibular teeth

Becoz less space

46
Q

● Some may be partially erupted. May mga iba
nakalabas.
● Teeth that did not erupt in the oral cavity or
erupted in the oral cavity but wrong
angulation/position.

IMPACTED TEETH
