DR. SANTIAGO ORREGO HAS received a $435,875 three-year research grant from NIH to develop a new voice- or vibration-activated “smart adhesive” designed to tackle the biggest reason tooth-colored fillings fail: recurrent decay that starts at the tiny space where the tooth and restoration meet. Unlike today’s adhesives, which behave like passive glue, this next-generation bonding layer is built from responsive smart materials designed to switch on protection when needed. With simple voices or everyday vibrations (even normal sound/vibration signals), the adhesive can be activated to deliver targeted, local prevention right at the restoration edge, helping disrupt harmful biofilms, neutralize acid attacks, and support mineral repair, so the seal stays stronger for longer. The vision is a game changer in dentistry: fillings that don’t just “sit there,” but actively defend their margins, reducing repeat replacements, lowering cost, extending restoration life and preserving more natural tooth over a patient’s lifetime.
