Accepted Answer

The first statement is true as inactive ingredients, such as binders and humectants, play a crucial role in maintaining the consistency and texture of dentifrices. They also enhance the flavor and mouthfeel of the product, making it more appealing to consumers. The second statement is also true as active ingredients, such as fluoride and tartar control agents, are responsible for the therapeutic effects of the dentifrice, such as preventing dental caries and controlling gum disease.

Question 3

Which dentifrice ingredient maintains moisture and prevents water loss from the product?&#10;A) Sodium lauryl sulfate&#10;B) Glycerol&#10;C) Xylitol&#10;D) Benzoate

Accepted Answer

Glycerol is a humectant that maintains moisture and prevents water loss from the product. Sodium lauryl sulfate is a surfactant that helps in foaming and cleaning, xylitol is a sugar substitute that prevents cavity formation, and benzoate is a preservative that prevents bacterial growth.

Question 6

Each of the following ingredients are used for sensitivity reduction EXCEPT one.Which one is the EXCEPTION?&#10;A) Arginine&#10;B) Potassium nitrate&#10;C) Stannous fluoride&#10;D) Zinc citrate

Accepted Answer

Zinc citrate is not typically used for sensitivity reduction; it is more commonly used in dental products for its anti-plaque and anti-gingivitis properties. Arginine, potassium nitrate, and stannous fluoride are all used to reduce tooth sensitivity.

It works by blocking the tiny tubes (dentinal tubules) that lead to the nerves in your teeth, reducing sensitivity to cold, heat, and touch. Triclosan, Zinc Citrate, and Chlorhexidine gluconate are not typically used for treating tooth sensitivity.
