Q

def

A

19
Q

Used to ensure standard caries measurement

A

ICDAS-International Caries Detection and Assessment System

20
Q

D1-D3 scale allows for

A

**KNOW THIS

ID lesion progression as well as initiation

21
Q

Limitations to DMF or def scoring

A

no information on severity

Scoring issues (i.e. extraction counts as caries on all sides even if just one caries caused extraction)

22
Q

Can survey and index info be used for treatment planning?

Why or why not?

A

NO-criteria may be different than clinical

23
Q

Significant Caries index (SiC) intended use

A

intended for use alongside the mean of DMF to give a complete summary

24
Q

ICDAS

A

The hopeful future classification system:

international- addresses gaps between American and European systems

25
Q

Primary Prevention

A

at the patient level

26
Q

Secondary Prevention?

Includes which levels of ICDAS?

A

addresses caries involvement that will not require restoration

ICDAS 1,2,3

27
Q

Tertiary Prevention

Includes which levels of ICDAS?

A

requires surgical intervention/restoration

ICDAS 4,5,6

28
Q

_______ is the basis for ICCMS

A

ICDAS

29
Q

ICCMS (define)

Based on what?

A

international caries classification and management system which addresses all diagnostic, preventative, and restorative decisions to be made

is based on the ICDAS-clinical protocols for managing caries

30
Q

Classification for caries by G.V. Black only included

A

tooth surfaces affected

31
Q

Is the D0-d4 scale reliable?

A

Training and calibration of examiners ensures it is

32
Q

How is the score of an index expressed?

A

as the mean

33
Q

Uses for an index

A

planning a resource allocation, monitoring/planning/implementing health services, enable study uniformity, patient counseling

34
Q

Is DMF(T) quickly “saturated”?

A

Yes, because each tooth is scored as a single point

35
Q

A tooth has several restorations, according to DMF scoring the tooth should be counted as how many teeth?

A

Just 1 tooth

36
Q

According to DMF scoring, teeth lost to what are counted?

A

Caries ONLY- DMFT includes caries and perio ONLY

37
Q

In communities where cavities are prevalent, discrimination between individuals may be obtained by counting the number of tooth surfaces affected…. In this case there are __ surfaces counted on anteriors and __ surfaces counted on post teeth

A

4 on ant and 5 on post

38
Q

Proposed ICDAS questions (4)

A

what stages of caries should be measured?

What are the definitions for each selected stage?

What is the best clinical approach to detect each stage in different tooth surfaces?

What protocols of examiners training can provide the highest degree of examiner reliability?

39
Q

DMFT includes what teeth

A

ONLY permanent

40
Q

Teeth which should NOT be counted as missing in a DMF include…

A

**KNOW THIS

Anything that is not from caries or perio… including

Unerupted teeth

Missing teeth due to accident

Congenitally missing teeth

Teeth that have been extracted for orthodontic reasons

41
Q

All of the limitations of the caries index

includes 12 things……yay

A

**KNOW THIS

-Index saturated in other older adults with high
caries activity.

-Difficult to account for sealed teeth.

-DMF data are of little use for estimating treatment
need.

  • DMFT value does relate to teeth at risk. It does not have a denominator
  • Does not always follow that the (f) component was filled due to caries-overestimate caries experience

-Provides no information on severity, only limited
information on extent of dental caries experience (i.e.,
tooth-rather than surface-related)

-Takes no account of treated and untreated caries, e.g.,
for a filled tooth with a separate untreated lesion

-Allocation of equal weight to the components of the
DMFT index is faulty for many purposes

-Allocation of equal weight to the components of the
DMFT index

  • It is more error prone
  • An mo or DO will be scored 2 even, though caries was originally present on only one surface

-Extracted tooth scores five, yet only two or three
surfaces might have been involved in the lesion
before extraction
