Background:

• Quantum dots (QDs) are artificial atoms with tunable energy levels, valuable in quantum information.
• Carbon quantum dots (CQDs) are explored for their unique properties.
• Enamel modification is crucial for dental applications.

Purpose of the Study:

• To synthesize and characterize CQDs.
• To investigate the effects of CQDs on enamel structure, crystal orientation, and mechanical properties.
• To evaluate the antibacterial efficacy of CQDs on enamel.

Main Methods:

• CQD synthesis via microwave irradiation.
• Enamel specimen treatment with varying CQD concentrations (0.1%–0.5%).
• Characterization using X-ray diffraction (XRD), density-functional theory (DFT), transmission electron microscopy (TEM), Raman spectroscopy, and atomic force microscopy (AFM).
• Antibacterial assessment using Lactobacillus biofilm analysis.

Main Results:

• CQD treatment, particularly at 0.5% concentration (CQD0.5%), altered enamel crystal orientation and improved lattice parameters.
• CQD0.5% demonstrated enhanced elastic modulus, nano hardness, and shear stress.
• CQDs exhibited significant antibacterial activity, with CQD0.5% preventing bacterial colony formation and inducing cell lysis.

Conclusions:

• CQD modification significantly alters enamel crystallite structure and mechanical properties.
• CQDs offer a promising approach for functionalizing enamel tissue.
• The 0.5% CQD concentration shows optimal antimicrobial properties for potential dental applications.
