Subsurface enamel remineralization by Lyophilized Moringa leaf extract loaded varnish

Area of Science:

• Biomaterials Science
• Dental Research
• Natural Product Chemistry

Background:

• Dental enamel demineralization is a precursor to caries.
• Developing effective remineralization agents is crucial for oral health.
• Moringa Oleifera Leaves (MOL) possess bioactive compounds with potential therapeutic properties.

Purpose of the Study:

• To investigate the enamel remineralization potential of lyophilized Moringa Oleifera Leaves (MOL) extract.
• To evaluate the efficacy of MOL extract incorporated into a varnish for enamel repair.

Main Methods:

• Seventy-five teeth were divided into five groups.
• Enamel windows were etched and treated with plain varnish, fluoride varnish, or MOL extract-loaded varnish (50 mg/ml and 200 mg/ml).
• Samples were incubated in artificial saliva for 14 days and analyzed using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX).

Main Results:

• SEM analysis showed that MOL extract-loaded varnish promoted the re-establishment of normal enamel architecture.
• Elemental analysis revealed significantly higher deposition of Calcium (Ca), Phosphorus (P), and Oxygen (O) in MOL extract-treated groups compared to fluoride varnish.
• The 200 mg/ml MOL extract group demonstrated superior results in enamel remineralization.

Conclusions:

• Lyophilized Moringa Oleifera Leaves (MOL) extract shows significant potential as a biomimetic material for enamel remineralization.
• MOL extract-based varnish can effectively guide and enhance the natural remineralization process of dental enamel.
• Further research into MOL extract as a natural alternative for dental restorative applications is warranted.
