1

Tetralogy of denta caries

Diet - high sucrose diet
Host - tooth
Microorg
Time - frequency(more impt) and duration

2

Triad of thumbsucking

Duration(most impt) - 6hrs
Frequency - am/pm
Intensity - 1 room away

3

Microorg in enamel caries

Strep mutans

4

Dentin caries

Lactobacillus acidophilus or casei

5

Microorg in root or cemental caries

Actinomyces viscosus

6

1st bacteria to colonize oral cavity (24hrs*) (or 10-12hrs)
Most numerous in oral cavity

Strep salivarius

7

First to colonize plaque
24-48hrs after toothbrushing

Strep sanguis

8

BQ: best technique for caries examination?

Visual examination

9

BQ: What is the adhesive used by microorg to stick to the tooth?

Dextran

10

BQ: What is the sugar that prevents glucose from binding to cariogenic microorganism?

Xylitol

11

Is caries smaller or larger in radiograph?

Smaller

12

Saliva prevents caries by

Remineralization
Acts as a buffer for acids
Use proteins, enzymes, antibodies that kill microorg
Wash food away

13

Normal ph of saliva

6.2-7.0 (weak acid)

14

Critical pH = dental caries

5.5

15

If pH in saliva is lower that 5.5

Erosion

16

Ig in saliva

IgA

17

Stretchy property of saliva

Spinnbarkeit test

18

BQ: Relationship of the 2 triangles in Pits and Fissure caries in the DEJ

Base to base relationship in the DEJ

19

BQ: Relationship of 2 triangles in smooth surface caries in the DEJ

Apex to base / Base to apex

20

BQ: BEST preventive measure for Pits and Fissure caries

PFS

21

BQ: Best preventive measure for SMOOTH SURFACE CARIES

Fluoride

22

BQ: Most sensitive part of the tooth during cavity prep

DEJ

23

Theory about tooth sensitivity

Hydrodynamic theory

24

BQ: most common site of proximal caries

Between contact area and gingiva

25

Shape or form of the conventional preparation that RESISTS DISPLACEMENT or removal of restoration

Retention form

26

Prevents FRACTURE of tooth and resto matl; withstand masticatory forces

Resistance form

27

Adequate observation, accessibility, ease of operation

Convenience form

28

Primary retention form of Class 1 prep

Converging Bu and Li occ = 90
(Or “diverging apically”)

29

Wall outside the preparation

Cavosurface

30

Resistance form of Class 1 prep (2)

PARALLEL or (diverging) Mesial and Distal walls

+ Flat pulpal floor
