|
|
Term
|
Definition
| Best radiograph for posterior carious lesions is the ____. |
|
|
Term
|
Definition
| Best radiograph for anterior carious lesions is the ____. |
|
|
Term
| 1st T, 2nd F (30% to see radiolucency) |
|
Definition
| T/F: Caries is deeper than it appears on radiographs. You cannot see the leading edge of lesion because there must be at least 50% destruction of hard tissue to see radiolucency. |
|
|
Term
|
Definition
| __ caries is a lesion that penetrates no more than 1/2 distance through enamel. Also called incipient caries. Appears as a radiolucent triangle with base at enamel surface and point halway to DEJ. |
|
|
Term
| False, can be seen on proximal, but not on occlusal because tooth and enamel is too thick |
|
Definition
| T/F: E1 caries can be seen radiographically on proximal surfaces and occlusal surfaces of molars/premolars. |
|
|
Term
|
Definition
| __ lesion penetrates more that 1/2 through enamel up to DEJ, also called moderate caries. Can be seen on proximal, but not usually on occlusal. |
|
|
Term
|
Definition

|
|
Term
|
Definition
| T/F: DEJ is weak spot where caries spread because dentin is softer than enamel. |
|
|
Term
|
Definition
| ___ lesion extends >1/3 but <2/3 toward pulp. |
|
|
Term
|
Definition
| ___ lesion extends more than 2/3 toward pulp. |
|
|
Term
|
Definition
| ___/___ lesions are rounded while ____ lesions are triangular. |
|
|
Term
| 1st F (cannot arise where root is covered by periodontium), 2nd T |
|
Definition
| T/F: Root caries can arise on roots covered by periodontium. Burn out is distinguished from root caries by lack of bone loss around exposed root. |
|
|
Term
|
Definition
| ____ ____ arise around existing restoration. |
