Exam 3 Flashcards
secondary prevention of caries should focus on
management of the caries process over time for individual patients, with a minimally invasive, tissue-preserving approach
What is the primary cause of oral pain and tooth loss
caires
What is the definition of dental caries
localized destruction of susceptible dental hard tissues by acidic by-products from bacterial fermentation of dietary carbohydrates
Assessment of the presence or absence of dental caries is dependent on…
the diagnostic cutoff points selected
Dental caries results from…
interactions over time between bacteria that produce acid, a substrate that the bacteria can metabolism, and many host factors that include teeth and saliva
Demineralization can be reverse in early stages through the uptake of…
Calcium, phosphate, and flouride Fluoride acts as a catalyst for the diffusion of calcium and phosphate into the tooth, which remineralizes the crystalline structures in the lesion.
What is the rebuilt crystalline surface composed of?
fluoridated hydroxyapetitie and fluorapatite, which are much more resistant to acid attack than the original structure
dental caries in enamel is typically first seen as…
white spot lesions, small areas of subsurface demineralization beneath the dental plaque
How are enamel and root surface caries different?
the surface of cementum can become softened and the bacteria penetrates further into the tissue at an earlier stage of lesion development.
Where does early childhood caries affect?
anterior tooth surfaces, maxillary or mandibular primary molars. begins as white spot lesions in upper primary incisors along gingival margin.
What happens in the moderate stage of early childhood caries?
cavitation takes place, caries begins to spread to the upper molars.
What happens in the severe stage of early childhood caries?
caries process destroys the upper teeth and spreads to the lower molars
True or false. evidence of a link between low birthweight babies and dental caries is inconclusive.
True
What is the major reservoir from which infants acquire strep mutans?
primary care giver. both horizontal and vertical transmission from human reservoirs
rate of progression of the disease slows down with…
increased age
caries decline in permanent teeth has been greater on what surfaces?
interproximal an dmsooth surface
Coronal caries in children’s permanent teeth is predominantly a disease of…
the pits and fissures. In early childhood caries lesions develop in smooth surfaces, which are usually at low risk factors of caries
caries diagnosis is done by…
visual examination
What is higher for visual examination, sensitivity or specificity?
specificity
The use of radiographs has a higher specificity or sensitivity?
sensitivity. Radiographs are not very helpful for anything but advanced dentinal lesions on occlusal surfaces
What does caries management approach rely on?
accurate diagnosis of disease and lesions, disease prevention, just-in -time restoration, minimally invasive operative procedures, and prevention of recurrence.
What is the most powerful intervention for caries prevention?
Flouride tooth paste
-high clinical effectiveness and social acceptibility
