Application of nanotechnology to dentistry: Impact of graphene nanocomposites on clinical air quality

Abstract

Concerns about air quality in dental clinics where aerosol generation during procedures poses significant health risks, have prompted investigations on advanced disinfection technologies. This editorial describes the strengths and limitations of ventilation and aerosol control measures in dental offices, especially with respect to the use of graphene nanocomposites. The potential of graphene nanocomposites as an innovative solution to aerosol-associated health risks is examined in this review due to the unique properties of graphene (e.g., high conductivity, mechanical strength, and antimicrobial activity). These properties have produced promising results in various fields, but the application of graphene in dentistry remains unexplored. The recent study by Ju et al which was published in World Journal of Clinical Cases evaluated the effectiveness of graphene-based air disinfection systems in dental clinics. The study demonstrated that graphene-based disinfection techniques produced significant reductions in suspended particulate matter and bacterial colony counts, when compared with traditional methods. Despite these positive results, challenges such as material saturation, frequency of filter replacement, and associated costs must be addressed before widespread adoption of graphene-based disinfection techniques in clinical practice. Therefore, there is need for further research on material structure optimization, long-term safety evaluations, and broader clinical applications, in order to maximize their positive impact on public health.

Core Tip: This editorial highlights the potential of graphene nanocomposites as a transformative solution for improving air quality in dental clinics. By leveraging graphene’s unique properties, including its antimicrobial activity and high adsorption capacity, these materials offer significant advantages over traditional air purification systems. The study by Ju et al demonstrated the effectiveness of graphene-based air disinfection, paving the way for its broader adoption in clinical practice. However, challenges such as cost, material saturation, and long-term safety must be addressed through continued research to optimize its application in dental and other medical environments.
