Flashcards in Lecture 7 - Caries Diagnosis and Management Deck (25):
1

with a visual exam, one should observe

frank cavitation
decalcification (white spot) - early stage caries due to partial demineralization
opalescence (deep caries)

2

T/F black/brown staining is not reliable indicator of caries

T

3

T/F diagnosis of fissure caries is easier than smooth surface caries

F - more difficult

4

reliability

relates to the reproducibility of measurements

5

validity

degree to which a measurement expresses the true value

6

what is the gold standard validity test for caries?

histologic exam

7

what validity test do we use for caries in vivo?

bitewing radiograph

8

sensitivity

proportion of people with caries with a positive test result
probability of disease when its there
P(T+/D+) a/a+C

9

specificity

proportion of healthy people with negative test result
how likely to say disease is absent when it is not there
P(T-/D-) d/B+D

10

reliability

inter-observed agreement
determined by measuring how often the same answer is achieved
kappa = 1 = perfect agreement

11

summary for diagnosis of fissure caries

diagnostic accuracy of probing and visual inspection similar
sensitivity LOW
specificity HIGH
reliability less than excellent
radiographs helpful

12

method of choice for diagnosis of fissure caries

visual inspection with appropriate radiograph

13

T/F
small lesions on radiographs are likely to be cavitated

F - not likely

14

T/F hidden, sealed caries will progress

FALSE!!!

15

Early enamel lesion
___________ sensitivity; ____________ specificity

low sensitivity
high specificity
(equivalent with visual exam vs explorer use)

16

false positives of caries detection dyes

DEJ
cirumpulpal

17

DIAGNOdent ________ specificity and ___________ sensitivity

decreases specificity - false positives
increases sensitivity - reliably establishes absence of disease

18

DIAGNOdent readings are related to the _____________ and _______________ of demineralization. NOT the ______ of lesion

degree
intensity
depth

19

INSPEKTOR PRO monitors what?

caries progression

20

name some fluorescent bacteria

veillonella
prevotella
(they fluoresce when substrate (sugar) is present)

21

QLF utility finds what? and determine what?

hidden caries
determines absence of disease

22

Canary number reflects what two things?

1 state of mineralization
2 crystallization

23

Saliva Check mutans test strip

SM tests have not been shown to be good risk predictors on individual basis

24

CRT caries risk test

Cultivation for s. mutans and lactobacilli

25

CariScreen Caries Susceptibility Test

measures ATP bioluminescence
detects levels of acid-producing, decay-causing bacteria
assesses caries risk
