|
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
| 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

|
|
Term

|
Definition
1) erosion: smooth margins, saucer shaped lesion

--> impacted teeth can have external resorption
-causes blunting of apices
