The effect of conditioned medium isolated from dental pulp mesenchymal stem cells (DPSC) treated with curcumin on oral pathogens

Objectives: The research sought to examine the antibacterial properties of the conditioned media derived from dental pulp mesenchymal stem cells (DPSC) that were treated with curcumin. Methods: An investigation of the physicochemical characteristics of curcumin nanoparticles was conducted utilizing scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and mapping techniques. The optimal dose of curcumin for treating DPSC cells was determined using the MTT test. The study investigated the antioxidant properties of curcumin on DPSC cells by measuring ROS. Two groups were isolated, one without treatment (control) and the other treated with curcumin. The antibacterial and antifungal properties of the supernatant culture medium of DPSC cells were then investigated. Results: The present study results indicate that curcumin possesses suitable physicochemical properties, including morphology and purity. Additionally, it exhibits no toxicity at doses ranging from 0 to 1.25 (μg/ml) and displays antioxidant properties at the IC50 concentration. Furthermore, it increases DPSCs. The antimicrobial results demonstrate that CM-CUR, at various concentrations, reduces the viability of Streptococcus mutans (S. mutans) and inhibits the growth of Candida albicans (C. albicans) by 85%. Conclusion: The research results indicate that the combination of CM-CUR is suitable for antibacterial and antifungal applications in dentistry to enhance human health.
