Lesson 3 Flashcards
What is the Latin meaning of ‘Caries’?
Dry rot
What is the definition of dental caries according to WHO?
A localized post eruptive, pathological process of external origin involving softening of the hard tooth tissue and proceeding to the formation of a cavity.
How did GV Black define dental caries?
The chemical dissolution of the calcium salts, first of the enamel then of the dentin by lactic acid.
What characterizes dental caries according to Shafer?
An irreversible microbial disease of the calcified tissues of the teeth characterized by demineralization of the inorganic portion and destruction of the organic substance of the tooth.
What is Kess and Ash’s definition of dental caries?
A disease involving hard portions of the teeth exposed in the oral cavity and characterized by disintegration of enamel, dentin, and cementum forming open cavities.
What does Last describe dental caries as?
An illness due to specific infectious agents or toxic products arising from the transmission of that agent or its products from an infected person, animal, or reservoir to a susceptible host.
What is Sturdevant’s definition of dental caries?
An infectious microbiologic disease of the teeth that results in localized dissolution and destruction of calcified tissues.
According to GJ Mount, what causes caries?
A prolonged imbalance in the oral cavity favoring demineralization of enamel and dentin over remineralization and repair.
How does Cawson define dental caries?
Progressive, irreversible bacterial damage to teeth exposed to the oral environment.
What is the cause of dental caries according to Kidd and Smith?
A disease of the calcified tissues of the teeth caused by the action of micro-organisms on fermentable carbohydrates.
What does Lundeen say about the progression of dental caries?
An infectious microbiological disease that results in localized dissolution and destruction of the calcified tissues of the teeth and progresses as a series of exacerbations and remissions.
How does Ernest Newburn define dental caries?
A pathological process of localized destruction of tooth tissues by microorganisms.
What is Ostrom’s perspective on dental caries?
A process of enamel or dentin dissolution caused by microbial action at the tooth surface mediated by the physiochemical flow of water dissolved ions.
What does Sikri describe as the cause of dental caries?
An infectious disease caused by an imbalance of oral micro-organisms leading to acid production and subsequently dissolving the hard tissues of the tooth.
According to Hume, what is dental caries essentially?
A progressive loss by acid dissolution of the apatite component of the enamel, dentin, or cementum.
What do Fejerskov and Nyvad define dental caries as?
A complex disease caused by an imbalance in physiologic equilibrium between tooth mineral and biofilm fluid.
How does Selwitz characterize dental caries?
A multifactorial disease that starts with microbiological shifts within the complex biofilm.
What is a caries lesion?
Tooth demineralization as a result of the caries process.
What type of caries is found on the anatomic tooth crown?
Coronal caries
What is the difference between primary and secondary caries?
Primary caries is NOT adjacent to an existing restoration; secondary caries is adjacent to an existing restoration.
What is a cavitated caries lesion?
A caries lesion that results in the breaking of the integrity of the tooth.
Fill in the blank: An _______ caries lesion is considered to be biologically active.
Active
What is rampant caries?
Presence of extensive and multiple cavitated and active caries lesions in the same person.
