Enamel Matrix Derivative, 58S5 Bioactive Glass, and Fluoride Varnish for Enamel Remineralization: A Multi-analysis...

Area of Science:

• Dental Materials Science
• Biomaterials Engineering
• Caries Research

Background:

• Dental caries remains a significant global health issue.
• Remineralization strategies are crucial for caries management.
• Novel biomaterials offer potential for enhanced enamel repair.

Purpose of the Study:

• To compare the in vitro enamel remineralization efficacy of enamel matrix derivative (EMD), experimental bioactive glass (BAG), and fluoride varnish.
• To evaluate the effects of different application methods on EMD's remineralization potential.

Main Methods:

• Artificial caries lesions were created on human enamel specimens.
• Specimens were treated with fluoride varnish, BAG, EMD+phosphoric acid (PA), EMD+EDTA, or a control.
• Remineralization was assessed using spectral domain optical coherence tomography (SD-OCT), surface microhardness (SMH), and fluorescence methods (FluoreCam, DIAGNOdent Pen).

Main Results:

• Fluoride varnish significantly reduced lesion depth.
• All tested agents improved surface microhardness compared to the control.
• BAG and EMD+PA exhibited remineralization comparable to fluoride varnish in SMH and lesion intensity.
• EMD+PA showed better SMH and lesion intensity than EMD+EDTA.

Conclusions:

• Experimental 58S5 BAG and EMD+PA possess remineralization capacities comparable to fluoride varnish.
• EMD+PA demonstrates superior surface microhardness and lesion intensity outcomes compared to EMD+EDTA.
• These findings suggest potential for BAG and EMD+PA as effective alternatives in enamel remineralization.
