A recent study conducted among individuals with mild to moderate dementia raises interesting questions about the relationship between oral health and dementia. Specifically, the study found that the presence of gum disease was associated with a s


Researchers have proposed using an intra-oral implant, similar to a dental implant, to deliver drugs into your body.

As unusual as this might sound, the structure and tissue of the mouth provide a receptive environment for pharmaceutical delivery. Given this, scientists believe that it may be possible to deliver drugs in a continuous manner via these implants. Doing so may minimize pain, and may have benefits for individuals who often undergo invasive procedures.

Two types of devices have been considered. The first is mechanical in nature, while the second is piezoelectric, which refers to the ability of some materials to generate an electric charge in response to applied mechanical stress. The drug delivery implant is conceived as being replaceable for reloading of the drug as needed.

While more evaluations and improvements are needed, experiments to date have been promising. The experiments indicate that the stress or impact of the delivery is only 10% of normal muscular force applied on opposing teeth. Moreover, delivery of the drug is within reasonable parameters.

The study was published in Sensors and Actuators B: Chemical.
