Which gel is known to have a caries prevention effect on teeth due to clinical studies?

The acidulated phosphate fluoride (APF) gel is well-documented in clinical studies for its effectiveness in caries prevention. This is largely due to its ability to enhance the uptake of fluoride into the tooth enamel, which is particularly beneficial in promoting remineralization of demineralized areas. The low pH of APF facilitates the solubility of fluoride, making it more available for absorption by dental hard tissues, which helps to prevent dental caries.

Research supports the use of APF gel, especially in professional applications, that demonstrate significant reductions in caries incidence when applied in clinical settings. The unique formulation of APF also allows it to remain on the tooth surface for a longer duration, leading to sustained fluoride release, which is critical in achieving optimal caries prevention.

In contrast, while other fluoride gels also have beneficial properties, their effectiveness in caries prevention may vary. For instance, sodium fluoride gel works primarily by releasing fluoride but may not have the enhanced remineralizing effect that APF provides. Stannous fluoride gel has antibacterial properties in addition to providing fluoride, but its gel might not be as widely recognized specifically for caries prevention compared to APF. Calcium fluoride is significant in the fluoride discussion but does not have the
