What features do zinc oxide-eugenol have?
Zinc oxide-eugenol is oil-based, low in strength, has a calming effect on pulp, and acts like temporary cement. The calming effect of pulp makes zinc oxide-eugenol useful when dealing with vulnerable tubules.
What allows caries to infiltrate the dento-enamel junction?
Frank caries is the type of caries that enters the dento-enamel junction. Enamel and underlying dentin meet at the dentinoenamel junction, where caries will swiftly develop laterally.
What is the drug uptake process called?
The drug uptake process is called absorption. How the drug is administered will determine the speed and efficiency of absorption in the bloodstream. Intramuscular, oral, transdermal, and intravenous drug administration sites are all available. Partial absorption is possible at intramuscular, oral, and transdermal sites while total absorption is possible only intravenously.
The restoration alloy and mercury mixture that has a track record for longevity and durability is:
Amalgam is a mercury and alloy restorative chemical that has a track record of durability. It serves as a filler for teeth. Silver, tin, copper, zinc, and mercury make up amalgam.
Enamel's structural degeneration is brought on by:
The structural destruction of enamel is caused by lowered pH that induces demineralization from physiochemical progression or acidogenic.
Beta-blockers, antipsychotics, diuretics, and anticholinergics are a few examples of medications that contribute to the reduction in:
Beta-blockers, anticholinergics, diuretics, and antipsychotics are a few examples of drugs that contribute to a reduction in sputum production, or Xerostomia. Saliva production is declining, which raises the risk of dental cavities. Fluoridation needs to be intensified.
What is bioavailability?
A drug's bioavailability is a measurement of how quickly and how much it gets into the bloodstream. The method of administration, gastrointestinal absorption processes, solubility, and drug chemistry all have an impact on bioavailability.
Caries can be successfully diagnosed and treated by:
Comprehensive patient history, thorough clinical evaluation, radiographic analysis, and risk assessment are all necessary for the diagnosis and management of caries. These metrics give a sense of the behavior of the patient, enabling flexible treatment strategies.
Website for drug administration includes:
Please select 2 correct answers
Intramuscular, oral, transdermal, and intravenous drug delivery sites are all available. Partial absorption occurs at intramuscular, oral, and transdermal locations while entire absorption occurs only intravenously.
Remineralization is described as being hard, discolored, asymptomatic:
Arrested carries are hard, discolored, asymptomatic, and remineralizing. These caries don't have any bacterial infections and are dormant.
What components make up cements?
For use in crowns, veneers, and inlays, cements are created by mixing liquid with powdered oxide or glass.
What is the most prevalent cariogenic bacterium at the root surface of caries?
Actinomyces viscus is the most prevalent cariogenic bacteria at the root surface of caries. It frequently collaborates with bacteria including Lactobacilli, Veillonella, and Staphylococcus. Low fever, soft lumps in the angle of the jaw that eventually solidify, and difficulty chewing are frequently associated with the infection. Additionally, the bacteria may be present in the belly, pelvis, and thorax.
What type of caries has a sudden start and severe oral decay?
Rampant caries, which are brought on by bad hygiene, consuming a lot of sweets, and xerostomia, have an immediate onset and extensive degeneration throughout the mouth. Patients who utilize stimulants are more likely to have xerostomia.
For remineralization of onset lesions to take place, what must be ample?
Fluoride must be present in sufficient amounts for onset lesions to remineralize. Fluoride naturalizes pH levels in large doses, allowing remineralization and stopping structural collapse.
Which three regions of carious dentin can remineralize?
Normal dentin, sub-transparent dentin, and transparent dentin are the three carious dentin zones that can remineralize. There are no microbes in the zones. Although demineralization might occur, remineralization is also a possibility. Dentin that is cloudy and diseased must be removed.
To identify dental caries:
It takes a tactical eye to spot caries. Opacifications, translucency changes visible with a curing wand, enamel color changes, cavitations, and the sensation of abnormalities on the tooth's surface are all signs of caries.
