Efficacy of Four Remineralizing Agents on Primary Teeth: In Vitro Evaluation Using Microhardness Testing and...

Area of Science:

• Pediatric Dentistry
• Dental Materials Science
• Caries Research

Background:

• Early childhood caries (ECC) is a significant public health concern affecting primary teeth.
• Incipient enamel lesions require effective remineralization strategies to prevent progression.
• Evaluating novel and existing agents for remineralization is crucial for pediatric dental care.

Purpose of the Study:

• To assess the remineralization potential of GC Tooth Mousse, Clinpro Tooth Crème, SHY-NM, and Pronamel on primary enamel.
• To compare the efficacy of these agents using microhardness testing and quantitative light-induced fluorescence (QLF).
• To identify effective agents for treating early-stage enamel demineralization in primary teeth.

Main Methods:

• An in vitro study utilized 100 intact primary anterior teeth subjected to demineralization.
• Microhardness and QLF testing were performed at baseline, after demineralization, and after 15 days of treatment with five groups (control, GC Tooth Mousse, Clinpro Tooth Crème, SHY-NM, Pronamel).
• Statistical analysis included ANOVA and paired t tests to evaluate changes in microhardness and QLF values.

Main Results:

• All tested remineralizing agents demonstrated an increase in microhardness and QLF values.
• GC Tooth Mousse (group two) showed a statistically significant increase in both microhardness and QLF values (P<0.05).
• SHY-NM (group four) exhibited a significant increase in microhardness values (P<0.05) but not QLF values.

Conclusions:

• GC Tooth Mousse and SHY-NM show significant potential as remineralizing agents for incipient lesions in primary teeth.
• These findings suggest that GC Tooth Mousse and SHY-NM can effectively aid in the repair of early enamel demineralization.
• Further clinical studies are warranted to confirm the efficacy of these agents in vivo.
