Often when we think about cavity prevention, any mention of the inclusion of fluoride usually makes us think that if it’s there, we’re less likely to get cavities. A recent study compared 400 children, 200 had sealants placed while the other 200 were the control group and did not receive sealants. Sealants were placed on cavity prone teeth areas. After 2 year, they found that those children who received sealants were 83% less likely to get cavities. They then compared the sealant group at the 2 year mark. Researchers found no difference between those that had molar teeth sealants with fluoride and those sealants that had no fluoride. The researchers concluded that sealants prevent cavities and the inclusion of fluoride did not increase the anti-cavity activity.
