Flashcards in Lec 7 - Class V RBC Deck (12):
1

loss of dental hard tissues by chemical action not involving bacteria

erosion

2

loss of tooth substance by tooth to tooth contact

attrition

3

loss of tooth substance from factors other than tooth contact

abrasion

4

loss of tooth substance from occlusal stresses

abfraction

5

non carious cervical lesion often has this playing a role

xerostomia

6

non carious cervical lesion from this often forms a v shape from brushing or toothpics etc

abrasion

7

non carious cervical lesion from teeth flexing and creates v shape notches

abfraction

8

we cannot differentiate blank based on lesion shape itself

etiologies

9

abfraction begins by loosening of the blank

cervical rods

10

during occlusal loading, stress concentrates at the blank point of the lesion so it will grow faster and faster

deepest point

11

minimal lesions with no sensitivity treatment

eliminate etiologic factors only

12

by placing a bonded restoration, the lesion will progress blank

slower rate
