Module 1 - Introduction Flashcards
Latin meaning of ‘Caries’
Dry rot
Implies slow disintegration of any biological hard tissue as a result of bacterial action
Caries
defined it as a localized posteruptive, pathological process of external origin involving softening of the hard tooth tissue and proceeding to the formation of a cavity.
WHO
defined it as the chemical dissolution of the calcium salts, first of the enamel then of the dentin by lactic acid
GV Black (Green Vardiman)
Tooth demineralization as a result of the caries process.
Caries Lesion
A caries lesion on a smooth tooth surface.
Smooth-surface caries.
A caries on a pit and fissure area
Pit-and-fissure caries.
A caries lesion on an occlusal surface.
Occlusal caries.
A caries lesion on a proximal surface.
Proximal caries.
A caries lesion in enamel, typically indicating that the lesion has not penetrated into dentin.
Enamel caries.
A caries lesion into dentin.
Dentin caries
A caries lesion on any surface of the anatomic tooth crown.
Coronal caries
A caries lesion in the root surface.
Root caries.
A caries lesion not adjacent to an existing restoration or crown
Primary caries.
A caries lesion adjacent to an existing restoration, crown or sealant.
Secondary or Recurrent caries
Refers to carious tissue that was not completely excavated prior to placing a restoration. Sometimes it is difficult to differentiate it from secondary caries.
Residual caries.
A caries lesion that results in the breaking of the integrity of the tooth, or a cavitation.
Cavitated caries lesion.
A caries lesion that has not been cavitated. In enamel caries, non-cavitated lesions are also referred to as “white spot” lesions
Non-cavitated caries lesion.
A caries lesion that is considered to be biologically active, is a lesion in which tooth demineralization is in frank activity at the time of examination.
Active caries lesion.
A caries lesion that is considered to be biologically inactive at the time of examination, that is, in which tooth demineralization caused by caries may have happened in the past but has stopped and is currently stalled.
Inactive caries lesion
Also referred to as “arrested caries”
Inactive caries
A term used to describe the presence of extensive and multiple cavitated and active caries lesions in the same person.
Rampant caries
Typically associated with “baby bottle caries” “radiation therapy caries” or “meth-mouth caries”
Rampant caries
formerly known as “baby bottle caries”
Early Childhood Caries
Critical level of pH for enamel and dentin
5.5 enamel, 6.2 dentin
Characteristics of Active caries
Brown, soft, painful
Characteristics of Inactive caries
Black, hard, not painful
Bacteria that causes enamel caries
Streptococcus mutans
Bacteria that causes dentinal caries
Lactobacillus acidophilus
Bacteria that cause root caries
Actinomyces Actinomycetemcomitans
Relationship between fluoride content and caries susceptability
Inversely proportional
Relationship between saliva viscosity and caries susceptability
Directly proportional
low viscosity > flowable saliva > low susceptibility
high viscosity > thick/sticky saliva > high susceptibility
