Exam 3: Chapter 24 Radiology- Key Terms

Front 1

Advanced Caries

Back 1

A classification of proximal surface caries. Category where caries has progressed all the way through the enamel, to or through the enamel, to or through the dentinoenamel Junction (DEJ) but less than halfway through the dentin toward the pulp.

Front 2

Arrested Carries

Back 2

Carries that is no longer progressing

Front 3

Buccal Caries

Back 3

Caries that involves the buccal surface of a tooth.

Front 4

Caries

Back 4

Disease of the calcified tissue of the teeth. The inorganic portion is demineralized and the organic tissues are destroyed

Front 5

Cemental (Root) Caries

Back 5

Caries that develops on the roots of teeth between the enamel border and the free margin of the gingiva.

Front 6

Cementoenamel Junction (CEJ)

Back 6

The area there the enamel covering the tooth crown meets the cementum covering the tooth root.

Front 7

Cervical Burnout

Back 7

A radiolucency often observed on the mesial and distal root surfaces near the cementoenamel junction. The radiolucent appearance is caused by the concave shape of the root at the cervical line and may be mistake for caries.

Front 8

Dentioenamel Junction (DEJ)

Back 8

The junction between the dentin and enamel of a tooth.

Front 9

Incipient (enamel) Caries

Back 9

The earliest stage of the caries process.

Front 10

Interproximal

Back 10

Between two adjacent tooth surfaces.

Front 11

Interproximal Caries

Back 11

See proximal caries: Caries found on the proximal surfaces (mesial and distal) of teeth.

Front 12

Lingual Caries

Back 12

Caries that involves the lingual surface of a tooth.

Front 13

Mach Band Effect

Back 13

An optical illusion that mimics the appearance of decay. Often occurs along boundaries of sharp contrast, especially around areas of slight overlapping between adjacent teeth.

Front 14

Moderate Caries

Back 14

A classification of proximal surface caries. Category where caries penetrate over halfway through the enamel toward the dentinoenamel junction (DEJ), but do not reach the DEJ.

Front 15

Nonmetalic Restoration

Back 15

Restoration containing no metal. May appear radiolucent, or radiopaque when radiopaque filler have been added to the restorative material.

Front 16

Occlusal Caries

Back 16

Caries found on the occlusal (chewing) surface of posterior teeth.

Front 17

Proximal Caries

Back 17

Caries found on the proximal surfaces (mesial and distal) of teeth.

Front 18

Rampant Caries

Back 18

Severe, unchecked caries that affect multiple teeth.

Front 19

Recurrent (Secondary) Caries

Back 19

Caries that occurs under a restoration or around its margins.

Front 20

Severe Caries

Back 20

A classification of proximal surface caries. Category where caries has penetrated over halfway through the dentin toward the pulp.
