Comparative Evaluation of Two Remineralizing Agents on Artificial Carious Lesion Using DIAGNOdent

Purpose

The current in vitro study was conducted to assess the remineralization potential of CPP-ACP and a customized dentifrice (tricalcium-phosphate) on artificial carious lesions using DIAGNOdent.

Materials and methods

Fifty-one extracted premolars that satisfied the inclusion criteria were painted using acid-resistant nail varnish. A window of 4 × 4 mm was exposed on the center of the buccal surface of each tooth. After 20 minutes of drying, the baseline reading of enamel specimens was assessed using DIAGNOdent. The teeth were then immersed in a bath of demineralizing solution. An incubation period of 96 hours at 37°C resulted in artificial caries-like lesions on the specimen. Readings of the specimen within the window after demineralization were recorded using DIAGNOdent for all the samples. The specimens were divided into three groups randomly [group I—casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), group II—customized dentifrice, group III—artificial saliva]. Samples were subjected to the daily treatment regimen for a period of 30 days. The samples were evaluated for remineralization by laser fluorescent device (DIAGNOdent) on the 15th and 30th day, respectively.

Results

The statistical analysis was done using the Friedman test, Kruskal–Wallis test, Wilcoxon sign rank test, and Mann–Whitney test. The results showed that both CPP-ACP and customized dentifrice showed almost similar remineralization potential but CPP-ACP showed significant remineralization (p < 0.001).

Conclusion

The DIAGNOdent observation conclusively proves that CPP-ACP and customized dentifrice remineralizes the demineralized tooth samples in vitro with CPP-ACP showing significant remineralization.
