Drill-free Fillings? Researcher Says Antimicrobial Resin Could Lead to ‘More Positive’ Patient Experience

Hetal Desai’s PhD research project will be welcome news to those who dislike having cavities filled.

The second-year PhD student in the University of Toronto’s Faculty of Dentistry is exploring a method to repair cavities without the need for a drill – typically used to remove decay from a tooth – by developing a low-viscosity resin with antimicrobial properties that would restore early carious lesions.

While there is currently a low-viscosity resin available that, when applied to the tooth’s surface, acts like a barrier to prevent further damage, the material doesn’t have antimicrobial properties. So, Desai hopes to use drug-loaded nanoparticles to levy antimicrobial properties onto this resin.
