Purpose: The purpose of this study was to compare the effectiveness of P11-4 self-assembling peptide (CurodontTM Repair [CR]) and fluoride varnish with xylitol-coated calcium phosphate (Embrace TM Varnish [EV]) on enamel permeability and in the management of white spot lesions (WSLs) in primary teeth.
Methods: A clinical trial was conducted among 30 children aged three to five years with WSLs in 60 anterior teeth. They were randomly assigned to receive CR or EV. Preintervention and postintervention evaluation was done by International Caries Detection and Assessment System (ICDAS) and morphometric analysis. The secondary outcome was to assess the enamel permeability using scanning electron microscopy (SEM) of polyvinyl siloxane impressions.
Results: A statistically significant reduction in the ICDAS scores (P=0.05) and percentage area of WSLs in morphometric analysis (P=0.008) was seen in the CR group after six months. No statistically significant difference was observed in the EV group after six months. The SEM evaluation did not show a significant reduction in the percentage area of droplets in both the CR and EV groups (P=0.06 and P=0.21, respectively). No significant difference was seen between EV and CR in the three parameters assessed.
Conclusion: Curodont TM Repair is effective at remineralizing white spot lesions in primary teeth and can be considered as a remineralizing agent.
