cariology Flashcards
four factors are essential for the initiation of dental caries?
1-micro organism
2-substrate(carbohydrates)
3-host(tooth)
4-time
exist in the mouth as an insignificantly small component of the oral flora?
MUTANS STREPTOCOCCI (MS)
strongly associated with the onset of caries?
MUTANS STREPTOCOCCI (MS)
associated with progression of
caries?
Lactobacilli
TRANSILLUMINATION
qualitative diagnostic methods by which teeth are transilluminated,
especially suitable for proximal caries.
Incipient caries appear as…… in the resultant images in Quantitative fiber-optic trans-illumination: (FOTI):
darker areas
Digital imaging fiber optic transillumination: (DIFOTI)
This device creates high-resolution digital images of occlusal,
interproximal and smooth surfaces.
cross sections on digital radiography
Tuned- aperture computed tomography (TACT)
It enables earlier and more accurate detection of “early” caries lesions which are not clearly visible to the human eye.
ELECTRIC RESISTANCE MEASUREMENT
Indicates through a color change whether decay or not.
CARIES DETECTOR DYES
LASER CARIES DIAGNOSIS SYSTEM
The laser wavelength is translated into a number from 0 to 99 Carious tooth structure shows higher degrees of fluorescence, as the amount of demineralization increases.
*False-positive results may arise by plaque or calculus
It aids the diagnosis of occlusal caries as an adjunct to visual inspection and radiographic examination. Battery quantitative diode laser fluorescence device
Diagnodent
It is a computer based method utilizes the blue green light from argon laser. It allows early detection of caries and monitoring the de- and remineralization process.
Quantitative laser fluorescence (QLF)
Initial microbial colonization
Actinomyces
The sugars with the most cariogenicity are
sucrose
glucose
