  • Particles including degradable material and anti-microbial agent
    Patent number: 5616315
    Abstract: A method for inhibiting bacteria in the mouth of a patient which includes placing a particle containing a degradable material and an anti-microbial agent in the mouth of the patient. The exterior of the particle is water-stable. The particles may be coated on dental floss or the bristles of a toothbrush, or incorporated into an oral rinse. Once placed in the mouth, the degradable material degrades to cause release of the anti-microbial agent, resulting in the inhibition of bacteria in the mouth.
