Improving Painless Fillings in the Developing World

Grade 9 - Bedford Academy

Inexpensive Glass Ionomer Cements (GIC) are used in the developing world to treat cavities. They do not require 'freezing' needles. GIC takes time to 'set' so less people can be treated in a given time. My experiment assessed whether ultrasound can reduce GIC setting time while maintaining acceptable compression strength. Results show ultrasound reduced setting time by 140 seconds while maintaining acceptable compression strength.
