Preventive and therapeutic benefits for Dentifrices

Prevention of dental caries
Remineralization
Reduction of biofilm
Reduction of gingivitis/inflammation
Reduction of dentin hypersensitivity
Reduction of supragingival calculus
Cosmetic effects

Which of the following is the primary agent that has shown efficacy in reducing gingival inflammation?
A) Xylitol
B) Triclosan
C) Zinc citrate
D) Stannous fluoride

B) Triclosan is the correct answer.
Triclosan is the primary agent for reducing gingival inflammation. Xylitol is a flavoring agent in some dentifrices that has been shown to provide anticaries benefits. Zinc citrate and stannous fluoride are agents used

Basic Components of Dentifrices

Detergent 1% to 2%
Abrasive 20% to 40%
Binder 1% to 2%
Humectant 20% to 40%
Flavoring 1% to 1.5%
Water 20% to 40%
Therapeutic agent 1.5% to 2%
Preservative 2% to 3%

Detergents

Foaming Agents/Surfactants

Abrasives

Cleaning/Polishing Agents

Binders

Thickeners and stabilizes formula

-Humectants
*Preservatives

-Moisture Stabilizers; prevents water loss/hardening of dentifrice
*prevents microorganisms from destroying the dentifrice in storage

-Flavoring Agents
*Water

-Sweeteners
*maintain the ingredient in formulation

In a dentifrice, what is the function of the humectant?
A) Prevents separation of ingredients
B) Prolongs a product's shelf life
C) Maintains the consistency of the product
D) Retains moisture

D) Retains moisture is the correct answer.
The purpose of the humectant is to retain moisture. The binder prevents separation and maintains consistency and the preservative prolongs shelf life.
