LP1 Flashcards
define dental caries
infectious disease caused by bacteria
what is the number one cause of complaints due to pain?
dental caries
In what ways can caries be classified by location? (3)
- Pits and fissures
- smooth surface
- root caries
Pits and Fissure caries; characteristics
pits and grooves of occlusal surfaces of pre-molars and moalars
lingual pits and grooves of maxillary incisors
buccal groove of mandibular molars
smooth surface caries: characteristics
facial, lingual, mesial, and distal surfaces
root caries characteristics
exposed root surface
who invented location by classification system in 1900
Dr. GV Black
Class I: Location
pits & fissures on occlusal surfaces of pre-molars and molars, Facial & lingual surfaces of molars and lingual surface of maxillary incisorrs
Class I: Method of Detection
- direct/indirect visual examination
- exploration
- no xrays needed
Class II: Location
-proximal surfaces of posterior teeth (occlusal surface is usually involved)
Class II: Method of Detection
- direct/indirect visual examination
- exploration
- no xrays needed
Class III: Location
proximal surfaces of incisors and canines (doesn’t involve incisal edge)
Class III: Method of Detection
- direct/indirect visual examination
- exploration
- xrays needed
Class IV: Location
proximal surfaces of incisors and canines including the incisal edge
Class IV: Method of Detection
- visual
- trans-illumination
- xrays needed
Class V: Location
gingival 1/3 of Facial and Lingual surfaces of teeth
Class V: Method of Detection
- visual
- exploration
- no xrays needed
Class VI: Location
cusp tips of posterior teeth
incisal edge of anterior teeth
Class VI: Method of Detection
- visual
- exploration
- no xrays needed
define cariology
science and study of dental caries
define carious lesion
decayed site/area on tooth
define dental caries
disease of the mineralized structures of the teeth characterized by demineralization of the hard components and dissolution of the organic matrix
-single or multiple area of decay are always referred to as caries
define arrested caries
also known as inactive caries
carious lesion that has become stationary and doesn’t show a tendency to progress further
define backward caries
also known as internal caries
lateral spread of decay at the DEJ through the undermining process
the surface lesion appears small but the destruction is extensive underneath
define incipient caries
also known as primary caries or early lesion
occurs on a surface not previously affected
define rampant caries
progressive caries occurring in many teeth simultaneously
what is the difference between acute rampant and chronic rampant caries
acute: rapid progression
chronic: slow developing
define recurrent caries
also known as secondary caries
carious lesion at the margin of or adjacent to an existing restoration
radiolucent area under an existing restoration which may be due to poor cavity preparation defective margins of restoration or incomplete removal of placement restoration
define early childhood caries
addressing caries process with the primary dentition
rampant smooth surface decay requiring urgent intervention formerly known as baby bottle caries or nursing bottle syndrome
