EXPOSED DENTIN

Answer 1

thermal
tactile
chemical
evaporative

Question 2

Organic Components
Inorganic Components
Dentinal Tubules

Answer 2

dentin

Question 3

Stimuli are transmitted to the pulp surface due to
the movement of fluid or semi-fluid within open
dentinal tubules

Answer 3

brannstrom’s hydrodynamic theory

Question 4

ETIOLOGY OF DENTINAL HYPERSENSITIVITY

Answer 4

1. gingival recession
2. enamel loss
   (both multiple factors)

Question 5

enamel loss:
1
2
3
4

Answer 5

1. abrasion
2. attrition
3. abfraction
4. erosion

Question 6

-anatomy of labial plate
-periodontal disease
-frenum involvement
-toothbrush abrasion
-poor oral hygiene
-inadequate attached gingiva
-periodontal surgery
-iatrogenic loss
-aggressive scaling/ root planing
-acute or chronic trauma
-excessive oral hygiene

Answer 6

gingival recession

Question 7

common factors in erosion

Answer 7

acid reflux disease (lingual surfaces)
bulimia
frequency of acidic drinks
frequency of acidic foods

Question 8

erosion occurs in all age ranges and higher incidence in

Answer 8

20-40 year olds
female more prone

Question 9

common site of occurrence for erosion

Answer 9

buccal and labial surfaces

Question 10

areas effected with erosion

Answer 10

canine/premolar
incisors
2nd pre-molars and molars

Question 11

(enamel/dentin) more easily abrasive

Answer 11

dentin
???idk worded weird

Question 12

teeth whitening in office

Answer 12

1. varnishes/precipitates
2. primers
3. placement of restorations
   -composite resin-based
   -restorations with glass ionomers

Question 13

treatment options for whitening at home

Answer 13

1. dentifrices, gels, rinses
   mode of action:
   -depolarizes nerve endings
   -tubule occlusion

Question 14

in office treatment
significantly reduce hypersensitivity immediately after treatment

reduces dentin permeability

Answer 14

glutaraldehyde/HEMA based agents

Question 15

in office treatment
forms a barrier over exposed dentin

relief provided by calcium fluoride deposits

Answer 15

5% sodium fluoride varnish
caries prevention and hypersens helper

Question 16

in office treatment/at home

replaces calcium and phosphate ions

Answer 16

MI paste
recaldent(CPP-ACP)
casein phosphopeptide- amorphous calcium phosphate

Question 17

how to use MI paste at home

Answer 17

apply with prophy cup in office??
at home use- applied after brushing teeth

Question 18

Interference with neural transmission (tooth paste):
dentifrices containing 5% potassium nitrate works by

Answer 18

penetrating the length of the tubule to depolarize the nerve endings

-frequent and regular application needed (show results after 2-3 weeks)

Question 19

tubule occlusion (tooth paste):
main active ingredients is

Answer 19

fluoride

1. stannous fluoride- most commonly used
2. arginine and calcium carbonate
   -hydroxyapatite

Question 20

prescription strength fluoride toothpaste

Answer 20

colgate prevident
5,000ppm (1.1% sodium fluoride)
