Imagine a future where cavities and enamel erosion are things of the past! An international research team has developed a groundbreaking, bio-inspired gel poised to revolutionize how we repair and protect our teeth. This innovative material has the potential to not only restore damaged enamel but also strengthen healthy enamel and prevent future decay.
The study, published in Nature Communications, details this exciting breakthrough.
This gel offers a simple application process, similar to the fluoride treatments dentists currently use. However, this new protein-based gel is fluoride-free and works by mimicking the natural proteins that guide enamel growth in infants.
When applied, the gel creates a thin, robust layer that penetrates the tooth, filling in microscopic holes and cracks. It then acts as a scaffold, drawing calcium and phosphate ions from saliva to promote controlled mineral growth through a process called epitaxial mineralisation. This allows the new mineral to integrate seamlessly with the existing tooth structure, restoring both the structure and properties of healthy enamel.
But here's where it gets interesting: The new material can also be applied to exposed dentin, creating an enamel-like layer on top. This is particularly beneficial for treating hypersensitivity and enhancing the bonding of dental restorations.
"We've tested the mechanical properties of these regenerated tissues under real-life conditions, like brushing, chewing, and exposure to acidic foods, and found that the regenerated enamel behaves just like healthy enamel," explains Dr. Abshar Hasan, the study's lead author.
"We are very excited because the technology has been designed with the clinician and patient in mind. It is safe, can be easily and rapidly applied, and it is scalable," adds Professor Alvaro Mata, the study's lead.
And this is the part most people miss: The versatility of this technology opens doors for various products to help patients of all ages dealing with enamel loss and exposed dentin.
