Some ways which dental caries can be prevented by are : 1. Fluoride 2. Fissure sealant Systemic Fluoride : ❑ Water fluoridation: The process of adjusting the fluoride content of fluoride-deficient water to the recommended level for optimal dental health. Recomended level of fluoride in drinking water is 0.7 milligrams per Liter (mg/L). ❑ Dietary fluoride supplements: Prescribed for high caries risk children ages ( 6 months to 16 years ) of age. Tablets, lozenges, drops, chewing gums. Topical fluoride : ❑ Self applied topical fluorides ✓ Fluoride containing toothpaste. ✓ Fluoride Mouth rinse or Gels. ❑ Professionally Applied topical fluorides ✓ Fluoride Mouth rinse, Gels, or Foams( more concentrated than the self-applied fluorides ) ✓ Fluoride-Containing Prophylaxis Paste. ✓ Fluoride Varnish. Fluoride gel Professionally Applied topical fluorides ▪ Carried to the oral cavity using a disposable tray ▪ Available in different colors and flavors Steps for fluoride gel application: 1.
