Treatment of Carious Lesions Using Self-Assembling Peptides


Treatment of Carious Lesions Using Self-Assembling Peptides

M Alkilzy et al. Adv Dent Res.


Modern approaches in caries treatment involve lesion management without tissue removal. Regenerative medicine focuses on replacing damaged tissues with biologically similar tissues. This article discusses the scientific evidence and clinical results for self-assembling peptides in modern caries management. The biomimetic remineralization promoted by self-assembling peptide P11-4 has been proven in vitro as an effective therapy for initial caries. P11-4 was rationally designed to promote formation of hydroxyapatite on its surface. The formulation was optimized to ensure the ability of monomeric P11-4 to penetrate past the subsurface lesions and assembly into a biomatrix within. Furthermore, P11-4 has shown that it assembles into fibers within carious lesions, and promotes the remineralization thereof. In a recent clinical study, the safety and efficacy of P11-4 in treatment of initial caries were evaluated. The additional effect of the application of P11-4 (Curodont Repair) was compared to the application of fluoride varnish (Duraphat) alone in active occlusal initial caries lesions on erupting permanent molars. In the 3- and 6-month recalls, the test group showed, both in the laser fluorescence readings and in the clinical assessment of the caries stage and activity, significantly superior lesion regression compared to the control group. No adverse events, medical complications, or allergic reactions related to the treatments were reported. Clinical applicability of treatment was regarded as satisfactory. Patients were happy to receive noninvasive caries treatments. In conclusion, biomimetic mineralization facilitated by P11-4 in combination with fluoride may present a simple, safe, and effective noninvasive treatment for early carious lesions.
