Terminology Flashcards
What is primary caries?
Original carious lesion of the tooth
What are pit and fissures?
Areas of imperfect coalescence of enamel lobes, prone to decay
What are smooth surface caries?
Caries in smooth areas of enamel covered with plaque
What is root surface caries?
Rapidly progressing caries on the root surface
What is the cementoenamel junction (CEJ)?
The junction between enamel and cementum
What is the dentinoenamel junction (DEJ)?
The junction between enamel and dentin
What are residual caries?
Caries that remain in a completed cavity preparation
What are secondary or recurrent caries?
Caries occurring at the borders of a restoration and progressing underneath
What is a white spot lesion?
Initial evidence of caries in enamel, appearing as a white opaque spot
What is a brown spot lesion?
A discolored remineralized white spot lesion, typically brown
What are cavitated caries?
Caries with enamel loss where remineralization is no longer possible
What are acute or rampant caries?
Rapid progression of caries
What is chronic caries?
Slow progression with alternating phases of activity and arrest
What is enameloplasty?
Grinding away enamel pits to create a smooth, cleanable surface
What is infected dentin?
Zone of decay where bacteria are present, collagen is denatured
What is affected dentin?
Zone of decay where collagen is denatured but can remineralize
What is abrasion?
Loss of tooth surface due to contact with foreign objects
What is erosion?
Loss of tooth surface due to chemical or mechanical action
What is attrition?
Loss of tooth surface due to tooth-to-tooth contact
What is idiopathic erosion (abfraction)?
Wedge-shaped defects due to microfractures, linked to parafunctional habits
What is cavity preparation?
Process of preparing a tooth surface for restoration
What is an axial wall?
Cavity wall parallel to the long axis of the tooth
What is a pulpal wall?
Cavity wall perpendicular to the long axis of the tooth
What are enamel rods?
Structural rods of enamel supported by dentin
