問題一覧

An infectious microbiologic disease of the teeth that results in the localized dissolution of the calcified tissues

Dental caries

Multifactorial, transmissible, infectious oral disease caused primarily by the complex interaction of cariogenic oral flora, biofilm, with fermentable carbohydrates on the tooth surface over time

Dental caries

consortium of microorganisms that stick to a tooth surface.

Dental biofilm

The microorganisms are embedded in an

extracellular polymeric matrix.

Filamentous microorganisms associated with the carious process

Denticolae

Filamentous microorganisms called DENTICOLAE were associated with the carious process

Parasitic theory

biofilm-mediated, diet-modulated, multifactorial, noncommunicable, dynamic disease resulting in net mineral loss of dental hard tissues.

Dental caries

determined by biological, behavioral, psychosocial, and environmental factors. As a consequence of this process, a caries lesion develops.

Dental caries

number of teeth/surfaces that have caries lesions (at a specified threshold), restorations, and/or are missing due to caries, accumulated by an individual, up to a designated point in time.

Caries process

Initial caries lesion is a frequently used term for

non- cavitated caries lesion

refers to the stage of severity and does not inform about lesion activity

Initial Caries Lesion

implies an early-stage lesion, the lesion could have been present in the mouth for a lifetime.

Initial Caries Lesion

- induced demineralization is the white spot lesion

First clinical sign of caries

White-SpotLesion=“WhiteSpot”

isapopulartermfornon-cavitatedlesionsinthe past.

• White-SpotLesion=“WhiteSpot”

White spot

double cone appearance with apices towards the pulp

Smooth-surface caries

A caries lesion on a proximal surface.

Occlusal caries

caries lesion on previously sound tooth surface A caries lesion not adjacent to an existing restoration or crown.

Primary caries

adjacent to an existing restoration, crown, or sealant.

Secondary Caries

demineralized carious tissue left in place before a restoration is placed.

Residual caries

intact tooth surfaces

Primary caries lesions

Recurrent caries adjacent to restorations

Secondary caries lesions

Caries lesion left behind in the preparation or at the enamel margin of a preparation when a restoration is placed

Remaining caries lesions

Hidden caries

Enamel caries

caries lesion that results in the breaking of the integrity of the tooth,

Cavitated Caries Lesion

Also referred to as “white spot” lesions.

Non-Cavitated Caries Lesion

lesion in which tooth demineralization is in frank activity at the time of examination

Active Caries Lesion

tooth demineralization caused by caries may have happened in the past but has stopped and is currently stalled.

Inactive Caries Lesion

Arrested caries

Rampant Caries

diagnose SPL from RPL, consider the following surface characteristics of the lesion: 4

degree of cavitation, discoloration, consistency and wetness of the involved dentin, subjective symptoms such as pain and hypersensitivity

ECC

The most accepted theory that explains dental caries formation, the acid theory, was proposed by W.D. Miller.

False

The loss of integrity of the tooth, the cavitation, is the earliest sign of dental caries.

False

The configuration of dental caries on smooth surface assumes double cone appearance with the apices pointing to the pulp.

True

A caries lesion adjacent to an existing restoration, crown, or sealant is a recurrent caries.

True

A carious lesion that has mineralized due to exposure to minerals in the saliva is called arrested caries.

True

Protective factors 3 dental caries

Saliva, Fluoride exposure, Oral hygiene

Contributing factors 4 dental caries

Oral flora, Feeding and eating practices, Limited fluoride exposure, Decreased salivary flow

net gain of mineral in previously demineralized tissue. The word remineralization can be misleading as it does not imply that the lesion has regained its original mineral content.

Remineralization

loss of tooth mineral, due to acids. In dental caries, this process is biofilm-mediated, while in erosion, the acid comes from other sources

Demineralization

CLASSIFICATION OF CARIES BASED ON SURFACE INVOLVED 2

Smooth-surface caries, Pit-and-fissure caries

CLASSIFICATION OF CARIES BASED ON ITS LOCATION 4

Occlusal caries, Primary Caries, Secondary Caries, Residual Caries

Active lesion

Arrested lesion

Acute (rampant) caries

Chronic (Slowly progressing) Caries

Arrested Caries

Slowly progressing lesions

Often painful or hypersensitive - soft, wet and light yellow - demineralization penetrates deep into dentin

Rapidly progressing lesions
