Varnish VLC: A Novel Solution for Tooth Decay and Erosion

Key Takeaways:

• Researchers at Queen Mary University of London have developed Varnish VLC, a new dental treatment to combat tooth decay and acid erosion.
• The treatment uses flake glass technology originally designed for industrial corrosion protection, such as on the Forth Bridge.
• Varnish VLC mimics natural enamel properties, offering superior wear resistance and long-term protection.
• A six-month trial is underway to assess its real-world effectiveness, with potential applications in preventive dentistry.
• The project highlights cross-disciplinary innovation and was supported by the Queen Mary Impact Fund.

Innovative Technology Adapted for Dental Use

Researchers at Queen Mary University of London have introduced Varnish VLC, a novel dental treatment aimed at addressing the widespread issue of tooth decay and acid erosion. According to an article published on News Medical, this treatment leverages flake glass technology, which has been historically used to protect industrial structures like tanks, pipelines, and steel bridges, including the iconic Forth Bridge. This technology provides up to 25 years of protection against harsh environmental conditions, making it an ideal candidate for adaptation into dental care.

Dr. Saroash Shahid, Reader in Dental Biomaterials at Queen Mary and lead researcher on the project, explained the rationale behind this unconventional approach: “It might sound unusual, but the challenges are similar: both teeth and bridges are exposed to harsh conditions, both suffer from corrosion, and both are difficult to protect. This project shows the power of looking outside of traditional fields for inspiration.”

The application of this technology marks the first time it has been adapted for use in dentistry, highlighting the innovative potential of cross-disciplinary research. By mimicking the natural properties of enamel, Varnish VLC offers a promising solution to a persistent oral health challenge.

Addressing a Growing Dental Health Concern

Tooth decay remains a significant public health issue, particularly among children and adults in England. Data cited in the article indicates that one-third of children and nearly half of adults in England are affected by tooth decay, leading to discomfort, costly treatments, and a substantial financial burden on the NHS. Current treatments, such as fluoride varnishes and resin infiltration, often fail to provide long-term protection against acid erosion.

Varnish VLC aims to address these limitations by offering enhanced wear resistance and protection while maintaining the natural appearance of teeth. Early in vitro studies suggest that the treatment outperforms existing solutions in both durability and effectiveness. Additionally, the minimally invasive nature of the application process ensures safety for patients and dental professionals, as it does not produce aerosols during use.

Dr. Shahid emphasized the potential impact of this innovation: “We believe this product has the potential to change preventive dentistry, particularly for children, and we are excited to bring it to all children in England and particularly those in our local community in East London.”

Real-World Testing and Industry Collaboration

To evaluate its efficacy, Varnish VLC is currently undergoing a six-month trial in real-world conditions. This phase is critical to determining whether the treatment can deliver consistent results outside of controlled laboratory settings. Queen Mary University is collaborating with PSP Dental to facilitate the rollout of the treatment to dental practitioners across the UK and internationally.

The project underscores Queen Mary’s commitment to translating academic research into practical solutions that address major health challenges. Through partnerships with industry leaders, the university ensures that its innovations have a tangible and widespread impact.

This initiative was made possible through support from the Queen Mary Impact Fund, which fosters projects with the potential to drive societal change. By combining cutting-edge research with strategic collaborations, the university continues to advance the field of dentistry.

Conclusion

The development of Varnish VLC represents a significant step forward in preventive dentistry. By drawing inspiration from civil engineering technology, researchers have created a treatment that addresses the shortcomings of current solutions while offering long-term protection against tooth decay and acid erosion. As the six-month trial progresses, the dental community and the public await further insights into the treatment’s real-world effectiveness. If successful, Varnish VLC could become a cornerstone of preventive dental care, benefiting millions of individuals worldwide.
