ORAL PATHOLOGY

Question 1

(ALTERATION IN SIZE)
small teeth

Answer 1

Microdontia

Question 2

(ALTERATION IN SIZE)
big teeth

Answer 2

Macrodontia

Question 3

● dark or gray
● Mostly soft tissue that’s why it absorbs
radiation hence having a dark or gray image

Answer 3

RADIOLUCENT

Question 4

extra teeth / calcification

Answer 4

Supernumerary

Question 5

● 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

Answer 5

RADIOPAQUE OR RADIOPACITY

Question 5

Absence of teeth / missing tooth

Answer 5

Anodontia

Question 6

tooth is impacted or tooth has not erupted
properly in the oral cavity

Answer 6

Impaction

Question 7

This term is used to describe teeth which are smaller
than normal

Answer 7

MICRODONTIA

Question 8

● 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).

Answer 8

Not all small teeth are microdontia

Question 8

3 types of microdontia are recognized:

Answer 8

1. True Generalized Microdontia
2. Relative Generalized Microdontia
3. Microdontia involving only a single tooth

Question 9

● All the teeth are smaller than normal
● Aside from its occurrence in some cases of pituitary
dwarfism, this condition is exceedingly rare.
● The teeth are reported well formed, merely small

Answer 9

TRUE GENERALIZED MICRODONTIA

Question 10

TRUE GENERALIZED MICRODONTIA

Answer 10

● 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.

Question 11

● Normal or slightly smaller than normal teeth
● Are present in jaws that are somewhere larger than
normal and
● There is an illustration of true microdontia

Answer 11

RELATIVE GENERALIZED MICRODONTIA

Question 12

RELATIVE GENERALIZED MICRODONTIA

Answer 12

● You have a large jaw. The teeth size are
normal. Nagmumukhang maliit yung teeth
due to large jaw

Question 13

Large jaw

Answer 13

Macrognathia

Question 14

Small jaw

Answer 14

Micrognathia

Question 15

● 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’ .

Answer 15

MICRODONTIA INVOLVING A SINGLE TOOTH

Question 15

● Is a rather common condition
● Affect most often that maxillary lateral incisor and the
third molar
● These two teeth are among those that are most often
congenitally missing

Answer 15

MICRODONTIA INVOLVING A SINGLE TOOTH

Question 16

● more common
● presence of normal or slightly larger than normal
teeth in small jaws
● The disparity in size gives the illusion of macrodontia.
● As in microdontia, the importance of heredity must
be considered.

Answer 16

RELATIVE GENERALIZED MACRODONTIA

Question 16

● Microdontia of the laterals itself
● Unusually smaller anatomy, shape & size
compared to the normal one.
● If you have this, you can retain the shape or
have veneers or composite restorations for it
to look normal

primate & leeway spaces

Answer 16

Peg shaped lateral

Question 17

● The condition in which all teeth are larger than
normal
● Has been associated with pituitary gigantism, but is
extremely rare

Answer 17

TRUE GENERALIZED MACRODONTIA

Question 17

● Refers to teeth that are larger than normal

Answer 17

MACRODONTIA

Question 18

● Result of relative generalized macrodontia sa
px.
● The small jaw has difficulty accommodating
the normal size. Big teeth.

Answer 18

CROWDING

Question 19

Relatively uncommon

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

hemihypertrophy of
the face,

Answer 19

MACRODONTIA OF SINGLE TEETH

Question 20

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

Answer 20

TRUE ANODONTIA

Question 20

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

Answer 20

NOLLA’S STAGES OF TOOTH DEVELOPMENT

Question 20

TRUE ANODONTIA may be 2 types:

Answer 20

1. Total 2. Partial

Question 21

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

Answer 21

TOTAL ANODONTIA

Question 22

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

Answer 22

TOTAL ANODONTIA

Question 22

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

Answer 22

HYPODONTIA / OLIGODONTIA

Question 23

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

Answer 23

CONGENITALLY MISSING DECIDUOUS TEETH

Question 24

● 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

Answer 24

SUPERNUMERARY TEETH

Question 25

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

Answer 25

Multiple supernumerary teeth

Question 25

How do you know if it is a supernumerary tooth?

Answer 25

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