Third molar
Unerupted teeth
Congenitally missing
Supernumerary
Teeth removed for any other reasons than caries
Primary tooth retained with the permanent successor erupted

Decayed Missing Filled (DMFT)

All the 28 teeth are examined
The teeth that are not included are: [?] x7

Decay
Carious cavity

stained

WHO Modification

o All [?] molars are included
o Temporary restorations are considered as [?]
o Only [?] are considered as D, initial lesions ([?] spots, [?] fissures) are not considered

once

Topic: Principles and Rules of DMF

No tooth is counted more than [?]

separately
restoration
recurrent

Topic: Principles and Rules of DMF

D, M or F teeth should be recorded [?]. When counting the decayed teeth, also count those teeth which have [?] with [?] decay

care

Topic: Principles and Rules of DMF

[?] must be taken to list the missing teeth

one

Topic: Principles and Rules of DMF

A tooth may have many restorations but is counted as [?]

False

Topic: Principles and Rules of DMF

True or False

Deciduous teeth are included

occlusal surface
incisal edge
gingival

Topic: Principles and Rules of DMF

A tooth is considered to be erupted when the [?] or [?] is totally exposed or can be exposed be gently reflecting the [?] tissue

Decayed missing filled teeth

DMFT means?

Decayed missing filled surface

DMFS means?

Decayed

Indicates the no. of permanent teeth that are decayed

True

True or False

Both cannot be counted as decayed and filled

Missing

Indicates the no. of missing permanent teeth due to decay

missing

Teeth which are badly decayed that they are advised for extraction are counted as [?]

history

[?] must be taken to identify that teeth have been lost due to caries

filling

what indicates the no of permanent teeth that have been attacked by the caries, and now restored fully and functionally good

restored
good

Filling indicates the no of permanent teeth that have been attacked by the caries, and now [?] fully and functionally [?]

one

Tooth that has several filling fillings is counted as [?]

individual dmft

what type of computation Identify each component separately and that add each component separately then add all subgroups

Group Average

Computation

Total D, M,F for each individual, then divide the total DMF by the no. of individuals in the group i.e

divide

To find the group average

Total D, M,F for each individual, then [?] the total DMF by the no. of individuals in the group

true

DMFT Limitation

True or False

Don't indicate the no of teeth that are at risk

periodontitis

DMFT Limitation

Can be invalid in older patients because become lost for the reasons other than caries like [?]

orthodontic

DMFT Limitation

Can be misleading in children because teeth may be lost for [?] reason

False

DMFT Limitation

True or False

Significant in the root caries

permant

DMFS are applied only applied to [?] teeth
