Dental caries remains a significant public health issue worldwide, prompting ongoing research into effective preventive measures. Fluoride has been the cornerstone of caries prevention for decades, while peptides, particularly those derived from milk proteins, have emerged as potential alternatives or adjuncts to fluoride treatments. This report reviews the current literature comparing the efficacy of peptides and fluoride in promoting dental health.

Fluoride: Mechanism and Efficacy

Fluoride is a naturally occurring mineral that has been widely used in dentistry for its caries-preventive properties. Its primary mechanisms include:

1. Remineralization: Fluoride enhances the remineralization of demineralized enamel by promoting the deposition of calcium and phosphate ions, forming fluorapatite, which is more resistant to acid than hydroxyapatite (Fejerskov & Kidd, 2015).
2. Inhibition of Demineralization: Fluoride reduces the solubility of enamel in acidic environments, thereby inhibiting the demineralization process (Marinho et al., 2003).

Numerous studies have demonstrated the effectiveness of fluoride in reducing caries incidence. A systematic review by Marinho et al. (2003) concluded that fluoride varnishes significantly reduce caries in children and adolescents.

Peptides: Mechanism and Efficacy

Peptides, particularly casein phosphopeptides (CPP), have gained attention for their potential in dental health. CPPs are derived from milk proteins and can stabilize calcium and phosphate ions, promoting enamel remineralization (Reynolds, 2008). Key mechanisms include:

1. Stabilization of Minerals: CPPs can form complexes with calcium and phosphate, preventing their precipitation and enhancing their availability for remineralization (Reynolds, 2008).
2. Antimicrobial Properties: Certain antimicrobial peptides have been shown to inhibit the growth of cariogenic bacteria, such as Streptococcus mutans (Koo et al., 2013).

Comparative Studies

Research comparing the efficacy of fluoride and peptide treatments has yielded mixed results. Some studies suggest that peptide-based treatments can be as effective as fluoride in promoting remineralization. For instance, a study by O’Sullivan et al. (2015) found that a CPP-ACP paste was effective in remineralizing early carious lesions, comparable to fluoride varnish.

However, fluoride remains the gold standard in caries prevention. A systematic review by ten Cate (2013) emphasized that while peptides show promise, they do not yet replace fluoride’s established role in caries prevention.

Combination Therapies

Recent studies have explored the potential benefits of combining fluoride with peptide treatments. Research indicates that such combination therapies may enhance the overall effectiveness of caries prevention strategies. For example, a study by Ganss et al. (2011) demonstrated that the combination of fluoride and CPP-ACP resulted in greater remineralization of enamel than either treatment alone.

Conclusion

Both fluoride and peptides have demonstrated efficacy in promoting dental health, albeit through different mechanisms. Fluoride remains the most widely accepted and effective agent for caries prevention. However, peptides, particularly CPPs, show promise as complementary treatments. Ongoing research is necessary to fully understand their potential and to explore combination therapies that may enhance caries prevention strategies.
