adhesive and bioactive restorative materials

recognition of minimal intervention

Question 5

Epidemiological assesments

Answer 5

prevalence and treatment need in population

Question 6

clinical assement

Answer 6

decision making for treatments

D1

Answer 7

initial caries but NO detectable loss of substance (can be significant staining or rough spots)

Question 8

D0

Answer 8

staining with sound surface

Question 9

D2

Answer 9

Enamel caries- the floor or walls are not softened and dentin is NOT affected

Question 10

D3

Answer 10

caries of dentin-SOFTENED floor or walls-Explorer point must enter the lesion with certainty

Question 11

D4

Answer 11

Pulpal involvement-Pulp should NOT be probed

Question 12

The method we use to measure caries

Answer 12

DMF (T)

Question 13

DMF (T) Explained

Answer 13

Decayed permanent teeth

Missing permanent tooth due to decay

Filled permanent teeth due to decay or periodontal disease (F is only caries T includes perio?)

T-teeth

Question 14

Index

Answer 14

a numerical scale with numerical scale with upper and lower limits, with scores on the scale corresponding to specific criteria (to a disease point/diagnosis)

Question 15

Properties of index

Answer 15

Valid, Reliable, Acceptable, Sensitive, Quantifiable, Clarity, Simplicity, and Objective

Question 16

DMF (S)

Answer 16

Sites and surfaces among adolescents

Question 17

def index

Answer 17

**KNOW THIS

used for children only

Question 18

def

Answer 18

decayed deciduous, extracted (indicated for extraction)

Question 19

Used to ensure standard caries measurement

Answer 19

ICDAS-International Caries Detection and Assessment System

Question 20

D1-D3 scale allows for

Answer 20

**KNOW THIS

ID lesion progression as well as initiation

Question 21

Limitations to DMF or def scoring

Answer 21

no information on severity

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

Question 22

Can survey and index info be used for treatment planning?

Why or why not?

Answer 22

NO-criteria may be different than clinical

Question 23

Significant Caries index (SiC) intended use

Answer 23

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

Question 24

ICDAS

Answer 24

The hopeful future classification system:

international- addresses gaps between American and European systems

Question 25

Primary Prevention

Answer 25

at the patient level

Question 26

Secondary Prevention? | Includes which levels of ICDAS?

Answer 26

addresses caries involvement that will not require restoration ICDAS 1,2,3

Question 27

Tertiary Prevention | Includes which levels of ICDAS?

Answer 27

requires surgical intervention/restoration ICDAS 4,5,6

Question 28

_______ is the basis for ICCMS

Answer 28

ICDAS

Question 29

ICCMS (define) Based on what?

Answer 29

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

Question 30

Classification for caries by G.V. Black only included

Answer 30

tooth surfaces affected

Question 31

Is the D0-d4 scale reliable?

Answer 31

Training and calibration of examiners ensures it is

Question 32

How is the score of an index expressed?

Answer 32

as the mean

Question 33

Uses for an index

Answer 33

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

Question 34

Is DMF(T) quickly "saturated"?

Answer 34

Yes, because each tooth is scored as a single point

Question 35

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

Answer 35

Just 1 tooth

Question 36

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

Answer 36

Caries ONLY- DMFT includes caries and perio ONLY

Question 37

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

Answer 37

4 on ant and 5 on post

Question 38

Proposed ICDAS questions (4)

Answer 38

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?

Question 39

DMFT includes what teeth

Answer 39

ONLY permanent

Question 40

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

Answer 40

**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

Question 41

All of the limitations of the caries index | includes 12 things......yay

Answer 41

**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
