The aim of this study was to evaluate the potential remineralization effect of Novamine and Er:YAG laser on artificial enamel lesions in primary teeth.
In this in vitro study, 30 sound buccal and lingual surfaces of human primary canines were randomly divided (6 per group) into 5 groups (Novamine, Laser, Novamine+ Laser, Positive control, and a negative control). Remineralization agents were applied for 1 min to teeth using a rubber cup after creating artificially demineralised lesions. EDX analysis was performed to evaluate the Ca/P ratio and take Scanning electron microscope images.
Data were analyzed using Kruskal Wallis analysis. Ca/P ratio was higher in all 4 groups than the negative control group, and higher in Novamine+ Laser group than the positive control group with a statistically significant difference between groups. Overall Ca/P ratio was found to be highest in the Novamine group followed by the laser then positive control group. There were no significant differences between groups regard to Ca/P Ratios.
Based on these result Er:YAG laser combined with Novamine was provided the greatest contribution to remineralization process of primary teeth.
