PhysiologyGlucose is reabsorbed via active transport mechanisms that involve sodium-glucose co-transporters (SGLTs) and glucose transporters (GLUTs).

Community DentistryFluoride is absorbed in the gastrointestinal tract and is distributed throughout the body. A significant portion of ingested fluoride is excreted through urine. However, fluoride also accumulates in skeletal tissues, including bones and teeth, where it can contribute to the mineralization process and enhance resistance to dental caries. The skeletal system retains fluoride, which can be beneficial in small amounts but may lead to toxicity if excessive.

ProsthodonticsDental porcelain is harder than enamel. Modern dental porcelains have hardness values that exceed natural enamel, which can lead to increased wear of opposing natural teeth. This is why careful occlusal adjustment and selection of appropriate porcelain types are important to minimize excessive wear of antagonist teeth.

Upon direct exposure of a healthy dental pulp to the oral environment, an acute inflammatory response occurs locally at the site of injury.

Oral PathologyCariogenic streptococci, particularly Streptococcus mutans, synthesize extracellular polysaccharides when exposed to high levels of sucrose. These polysaccharides are primarily dextran-like glucans, which are formed from the polymerization of glucose units. Dextran contributes to the formation of dental plaque and biofilm, facilitating the adherence of bacteria to tooth surfaces and promoting caries development.

The Curve of Wilson is a concept in dental occlusion that refers to the mediolateral curve of the occlusal plane. It is concave in the mandibular arch and convex in the maxillary arch, which helps to align the teeth in the transverse plane.

Dental Materials
Acid etching selectively dissolves the hydroxyapatite crystals in dentin, creating microscopic tags and channels for resin infiltration, which enhances the bond between the restorative material and the tooth structure.

The elastic range of a wire is the amount of deflection it can withstand before permanent deformation occurs. It is the difference between the elastic limit and the ultimate tensile strength.

Oral SurgeryIncrease the rate of liver metabolism of local anesthetic: Alpha adrenergic agonists, such as epinephrine, are often added to local anesthetics to enhance their effectiveness. They achieve this by causing vasoconstriction at the injection site, which reduces bleeding and increases the duration of anesthesia. However, they do not directly increase the concentration of LA at the receptor site or alter liver metabolism. Therefore, the correct answer is 2) Increase the concentration of LA at receptor site.
