What is a function of fluoride?Multiple choice question.Prevention of dental cariesContributes to hydroxyapatite

Analysis of Options

1. Prevention of dental caries:

   • Fluoride is well-known for its role in preventing dental caries (tooth decay). It helps to remineralize enamel that is beginning to demineralize and makes teeth more resistant to future acid attacks from bacteria.

2. Contributes to hydroxyapatite:

   • Fluoride also contributes to the formation of hydroxyapatite, which is a natural mineral form of calcium apatite. Hydroxyapatite is a key component of tooth enamel and bone.

Verification

Both options represent valid functions of fluoride. The primary role of fluoride in dental health is indeed its ability to prevent dental caries, but it also contributes to strengthening teeth through the formation of hydroxyapatite.

Final Answer

Both options provided are correct; however, if selecting the most direct function of fluoride, Prevention of dental caries would be considered the primary option.
