Dental Caries

The slow disintegration of any biological hard tissue as a result of bacterial action.

2
New cards

WHO

defines dental caries as a localized posteruptive, pathological process of external origin involving softening of the hard tooth tissue and proceeding to the formation of a cavity.

3
New cards

GV Black

defined dental caries as the chemical dissolution of the calcium salts, first of the enamel then of the dentin by lactic acid.

4
New cards

Shafer

defined dental caries as 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.

5
New cards

Kess and Ash

Dental caries is a disease involving hard portions of the teeth exposed in the oral cavity and is characterized by disintegration of enamel, dentin, and cementum forming open cavities.

6
New cards

Last

Dental caries is an illness due to specific infectious agents or toxic products that arise through the transmission of that agent or its products from an infected person, animal, or reservoir to a susceptible host.

7
New cards

Sturdevant

Dental caries is an infectious microbiologic disease of the teeth that results in localized dissolution and destruction of calcified tissues.

8
New cards

GJ Mount

Caries is perceived to be a prolonged imbalance in the oral cavity such that the factors favoring demineralization of enamel and dentin overwhelm the factors that favor remineralization and repair of those tissues.

9

Cawson

Dental caries can be defined as progressive, irreversible bacterial damage to teeth exposed to the oral environment.

10
New cards

Lundeen

Dental caries is 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.

12
New cards

Ernest Newburn

Dental caries or tooth decay is a pathological process of localized destruction of tooth tissues by microorganisms.

13
New cards

Ostrom

Dental caries is a process of enamel or dentin dissolution that is caused by microbial action at the tooth surface and is mediated by the physiochemical flow of water dissolved ions.

14
New cards

Hume

Dental caries is essentially a progressive loss by acid dissolution of the apatite (mineral) component of the enamel then the dentin, or of the cementum, then dentin.

15
New cards

Fejerskov and Nyvad

Dental caries is a complex disease caused by an imbalance in physiologic equilibrium between tooth mineral and biofilm fluid.

16
New cards

Selwitz

Dental caries is a multifactorial disease that starts with microbiological shifts within the complex biofilm. It is affected by salivary flow and composition, exposure to fluoride, consumption of dietary sugars, and preventive behaviors, like cleaning the teeth. However, it is mainly a disease that dates back to antiquity and has also occurred in populations that have never used sugar or processed foods.

17
New cards

Sikri

Dental caries is an infectious disease caused by an imbalance of oral microorganisms leading to acid production and subsequently dissolving the hard tissues of the tooth.
