dental caries
| Question | Answer |
|---|---|
| what does the term caries mean | tooth decay |
| what is the caries risk test | test for cariogenic bacteria |
| what is cavitation | formation of a cavity or hole |
| what is demineralization | loss of minerals from the tooth |
| what is early childhood caries | decay in any primary teeth |
| what are fermentable carbohydrates | simple carbohydrates, such as sucrose,fructose, lactose,and glucose |
| what is fluoride | mineral used in dental products to make teeth more resistant to decay |
| what are incipient caries | tooth decay that is beginning to form or become apparent |
| what is lactobacilli | bacteria that produce lactic acid from carbohydrates |
| what is mutans streptococci | a type of bacteria primarily responsbile for caries |
| what is a pellicle | a thin film coating of salivary materials deposited on tooth surfaces |
| what is plaque | soft deposit on teeth that consists of bacteria and bacterial by-products |
| what is rampand caries | decay that developes rapidly and is widespread throughout the mouth |
| what does remineralization mean | replacement of minerals in the tooth |
| what is the saliva flow rate test | determines flow rate of saliva in milliters per minute |
| what is xerostomia | dryness of the mouth caused by reduction of saliva |
| what is xylitol | ingredient in chewing gum that has an antibacterial effect against decay-causing bacteria |
| what is the single most common chronic disease in children | dental caries ( tooth decay ) |
| what are the two specific bacteria in the mouth that are responsible for caries | mutans streptococci and lactobacilli |
| what bacteria in a patient's mouth indicates that the patient has a high sugar intake | lactobacilli |
| the oral cavity of a newborn does not contain what | mutans streptococci |
| how is the bacteria mutans streptococci transmitted to the infant | the mothers saliva |
| a milligram of wet plaque may contain as many as _______ to _______ MILLION microorganisms | 200-500 |
| what is the most highly mineralized tissue in the body and is stronger than bone | enamel |
| what in enamel allows minerals to flow out of the tooth and acids to flow into the tooth | water |
| what mineral in enamel makes it easier for the tooth structure to dissolve | carbonated apatite |
| what 3 factors must be present at the same time for caries to develop | a susceptible tooth, a diet rich in fermentable carbohydrates, and specific bacteria |
| with in ______ after eating or drinking , bacteria begin to produce acids as a by-product of their digesting your food | 5 minutes |
| what 4 general areas of the tooth can carious lesion occur | pits and fissures, smooth surface, root surface, and secondary or recurrent |
| how long can it take for a carious lesion to develop | months or years |
| demineralization occurs when : | calcium and phosphate dissolve from hydroxyapatiet crystals in the enamel |
| when calcium and phosphate are redeposited in previously demineralized areas what process just occured | remineralization |
| carious lesions develop in what two distinct stages | incipient caries and cavitation |
| what 6 ways can you control tooth decay | diet,fluorides,remove plaque,increse flow of saliva, antibacterial mouth rinses, and dental sealants |
| what "color" or what term is used for early carious lesions | white spots |
| what condition is marked by multiple lesions throughout the mouth | rampant caries |
| usually rampant caries occurs after what | excessive and frequent intake of sucrose or after xerostomia |
| what lesions form more quickly because the cementum is softer in this area | root surface |
| what kind of caries start to form in tiny spaces between the tooth and the margins of a restoration | secondary ( recurrent ) caries |
| what is required to detect recurrent caries | radiograph |
| what is another term for early childhood caries | baby bottle tooth decay |
| saliva is like miracle fluid that provides what measures for the teeth | physical, chemical, and antibacterial |
| when a sharp explorer tip is pressed into an area of suspected caries what will it do when it is being removed | stick |
| the extent of caries can be misdiagnosed easily because the caries is often ____ times deeper and more widespread than it appears on radiographs | two times |
| the visual appearance of teeth that could indicate caries is what | darkly stained grooves, and gray shadowing underneath enamel |
| what is an indicator dye used for | to show remaining decay in a cavity preparation through color change |
| what happens when a laser caries detector is used | the laser beam passes through a change in the density of the tooth, it gives off a fluorescent light of different wavelengths |
| when using the laser caries detector , carious tooth structure shows what degrees of fluorescence | higher |
| what limitations does the laser caries detector have | can not be used to diagnose interproximal caries, or caries located under detnal sealants or under an amalgam restoration |
