Evaluation of the Remineralizing Effect of Self-assembling Peptide P11-4 on Caries Affected Dentin.

It is possible to find numerous noninvasive or minimally invasive therapies for caries such as hygiene education, fluorides, Phosphopeptide compounds, xylitol and infiltrative resins.

However, when caries progresses to the point of breaking down the dental tissues, composite restorations are imperative to preserve the tooth functionality.

During the execution of routine dental restorations, the hybrid structure formed by the dental bonding procedure occurs through the interaction and subsequent polymerization of monomers around the demineralized collagen matrix.

The oral cavity is a severe environment for the resin-dental bond to survive for a reasonable length of time, with thermomechanical changes, chemical attacks by acids and enzymes and other factors posing routine daily challenges. Therefore to achieve effective and stable bonding, the preservation of dentin collagen is critical, since collagen represents the major organic component of the dentin matrix.

Based on today's understanding of the dental biomineralization process, new efforts have been made to develop synthetic analogues of non-collagenous proteins (NCPs), which are involved in the events of nucleation and growth of hydroxyapatite crystals in hard tissues Such analogues have been designed mirroring the amphiphilic characteristics of NCPs, with polar groups complexing inorganic ions and non-polar side chains governing the matrix-matrix interactions.
