Efficacy of Four Remineralizing Agents on Primary Teeth: In Vitro Evaluation Using Microhardness Testing and Quantitative Light-induced Fluorescence.

PURPOSE

This study's purpose was to evaluate the remineralization of primary enamel using GC Tooth Mousse, Clinpro Tooth Crème, SHY-NM, and Pronamel by employing microhardness testing and quantitative light-induced fluorescence (QLF) values.

METHODS

An in vitro study was performed with 100 intact primary anterior teeth. After specimen preparation, they were subjected to baseline microhardness and QLF testing. The specimens were immersed in demineralizing solution, subjected again to microhardness and QLF testing, and divided randomly into five groups of 20 teeth: group one-control group (artificial saliva); group two-GC Tooth Mousse; group three-ClinPro tooth crème; group four-SHY-NM; and group five-Pronamel. The pastes were respectively applied for the specific group specimens for 15 consecutive days. The samples were subjected to microhardness and QLF testing.

RESULTS

The results were analyzed using analysis of variance testing. A post-hoc comparison was done using a paired t test. There were mean increases in microhardness and QLF values with all remineralizing agents. Group two showed a statistically significant increase (P<0.05) in microhardness and QLF values. Group four showed a significant increase only in microhardness values. (P<0.05).

CONCLUSION

GC Tooth Mousse and SHY-NM are promising materials for remineralizing incipient lesions in primary teeth.
