patient takes many meds for arthritis and blood pressure; these make her mouth dry. She sucks on candies to help with dry mouth. she drinks one glass of water a day as well as ginger ale. what is the most likely factor of her new root caries | The most likely risk factor would be the dry mouth followed by the sugary substance because the sucrose in her candy causes the ph level to drop below crtical level. |

magine that you are holding an “interview” of bacteria living in an oral biofilm. How might the bacteria respond to your question about advantages of living in a biofilm? List three MAJOR advantages | they're protected by an extracellular slime layer that's resistant to antibiotics, antimicrobial agents& the bodes immune response, this aids in long term survival of the bacteria. They're not easily destroyed, in this biofilm they are able to communicate |
LIST the Factors involved in the Formation of a Carious Lesion (cavity)… | Fermentable carbohydrates + Bacteria + Host (tooth)= over time- DECAY |
How does saliva protect the teeth from dental caries? | it neutralizes ph in the vicinity of the tooth surface |
What precautions are necessary for children using fluoridated toothpaste? | seek advice from a dentist or healthcare professional before introducing a fluoridated toothpaste supervise child while brushing to discourage swallowing only a small pea sized amount of fluoride tooth paste on brush |
As a dental assistant, you have been asked to speak to a group of pregnant women regarding their dental health. Why is it important for these pregnant women to have excellent dental health before their babies are born? | have dental care during pregnancy to prevent transmission of caries from mother to baby. I would also suggest they rinse with baking soda if they experience morning sickness as this will help prevent erosion, use fluoride to prevent caries in child |
twins are in your dental office mom informs you that they both eat the same amount of sweets. However, Christie eats her sweets all at once, but Callie divides her sweets throughout the day. Which of the twins is most likely to have tooth decay? Why? | callie because the teeth are not allowed to demineralize and remineralize like they are when christie eats her sweets all at once |
new patient in. His medical history indicates that he is taking medications for his Type I diabetes mellitus. On the basis of this information, do you think you might see any unusual conditions in his oral tissues? If so, what and why? BE SPECIFIC. | ask if how they maintain diabetes, and what they last ate. slow healing of wounds harder to fight infections xerostomia aand high blood sugar levels can contribute to periodontal disease in diabetic patients |
new patient in. He indicates that he smokes 1/pk a day of cigarettes, takes no medications, and “notices his front teeth are loose”. What is the relationship between smoking and periodontal disease? BE SPECIFIC. | observe oral cavity first. look for inflamed gums bleeding & open sores. smoking is the leading cause of periodontal disease. It restricts the blood vessels making blood hard to get to the area to fight off bacterias. healing is harder for smokers |
A 10 year boy does not think he should give up eating sweets all day long? How would you present patient ed? | inform the patient of remineralization and demineralization. when you constantly snack you cause demineralization which = caries. so if you snack all day you get caries and with caries comes restoratives. |
