|
Definition
|
|
Term
things that affect appearance of caries |
|
Definition
1) x-ray beam angle: important when trying to identify recurrent caries since changes in angulation can cause superimposition of existing restoration w/ lesion
2) buccolingual thickness of tooth
3) 2D film: can't see extent of carious involvement buccolingually
4) exposure: lower kVp helps bc it provides higher contrast |
|
|
Term
|
Definition
1) incipient 2) moderate 3) advanced 4) severe |

Definition
take an xray from another angle...it will disappear if it's cervical burnout |
|
|
Term
2 reasons why cervical burnout happens |
|
Definition
1) invagination of the proximal root surface allows more x-rays to pass through this area, causing it to look more radiolucent 2) space between where enamel ends and bone starts will look more radiolucent than either than enamel or bone |
|
|
Term

|
Definition

|
Definition
a restoration that isn't amalgam |
|
|
Term
acquired abnormalities that aren't caries |
|
Definition
1) erosion: smooth margins, saucer shaped lesion 2) external resorption: idiopathic, replaced with bone --> impacted teeth can have external resorption -causes blunting of apices 3) sclerosis: increased bone, makes it hard to see pulp even though tooth is vital 4) internal resorption: starts in pulp chamber 5) pulp stones: opacity in pulp chamber, no tx 6) hypercementosis 7) dilaceration 8) Turner tooth 9) submerged tooth |
