Why should pit and fissure sealants be used in combination with fluorides?

Using pit and fissure sealants in combination with fluorides is particularly effective for the prevention of other types of caries because both agents serve complementary roles in dental care. Pit and fissure sealants are designed to physically seal the grooves and pits in the teeth, which are hard to clean and susceptible to plaque accumulation and decay. By preventing bacteria and food particles from accumulating in these areas, sealants significantly reduce the risk of caries forming in those sites.

Fluorides, on the other hand, work by enhancing the remineralization process of teeth, making them more resistant to acid attacks from plaque bacteria. Fluoride can penetrate areas that might be initially demineralized and help restore enamel health, thereby reducing the likelihood of caries development not only in pits and fissures but also in smooth surfaces and interproximal areas.

When used together, sealants and fluorides create a comprehensive preventive strategy. This dual approach maximizes caries prevention across various tooth surfaces, leading to healthier teeth and a reduced incidence of dental caries in the population. This synergy is particularly beneficial for children and adolescents, who are at a higher risk for dental caries in their permanent teeth.
