Ch.15 Review Flashcards
Cementum is more susceptible to root caries than enamel because
It has less mineral content and is more soluble
Besides dry mouth what is another thing xerostomia can cause
Reduced salivary flow
True or False: Dental plaque contains food debris and does not contain bacteria.
False
___________ caries is the first stage of development of various lesions.
Incipient
Early childhood caries is the most prevalent disease of ______________.
Tooth decay
Doing this three times a day will increase saliva flow, neutralize mouth acids, and assist in the remineralization of tooth surface.
Chewying xylitol gum
Mutants Streptococci and lactobacilli are groups of bacterial responsible for ___________
Dental Caries
What are the three factors for development of caries?
Susceptible tooth, specific bacteria, fermentable carbohydrates
An increase of saliva flow can _________ or ________ the caries process
Slow / prevent
The ____________ includes the causes of dental caries, process of caries development, science and practice of caries management and prevention.
Study of cariology
__________ is caused by the bacterial acid released after eating fermentable carbohydrates.
_________ also is increased as fermentable carbohydrates are exposed and eaten more frequently.
Incipient caries / rampant caries
________________ is an infectious disease in which children live in constant pain for decayed primary teeth and swollen gums.
Early childhood caries
A DIAGNOdent reading of greater than 80 indicates which action?
Reclean, dry and re-examine the tooth
___________ bacteria is found in relatively large numbers in dental plaque
Streptococcus mutans
The __________ is dependent on the water content in saliva and the amount or flow of saliva
Physical protection
Advances in __________ will provide dental professionals with a rapid method of assessing a patients risk fro dental caries.
CAMBRA
Pit and fissure caries occur primary on ________ surfaces.
Occlusal
What does the “M” in CAMBRA stand for?
Management
True or False: Several types of devices have been developed that can provide a high level of discrimination than an explorer in the diagnosis of dental caries
True
____________ occurs when calcium and phosphate dissolves from hydroxyapatite in the enamel
Demineralization
A __________ caries detector cannot be used to detect caries under an amalgam restoration
Laser
Dental caries is a communicable _________ disease
Chronic
Bacteria in dental plaque feed on __________ including sugar, cooked starches, and fruit sugar
Fermentable carbohydrates
____________ is the primary reason why root caries is becoming more prevalent
People are keeping their teeth longer
When using a laser caries detector on a clean healthy tooth will have little or no fluorescence, resulting in a _________ reading.
Very low
Salvia flow rate and bacterial testing is an example of _____________ assessment tests
Caries risk
____________ are the most common source of transmission of disease-causing mutants streptococci (MS0 to infants?
Mothers
True or False: Demineralization and remineralization always causes loss of tooth structure
False
Early childhood caries is not as common in kids living areas with ________ water
Fluoridated
True or False: Laser caries detector is not useful for location subgingival caries
True
