Are you interested in materials research? The Dr. J Murray Gavel Center, established in 1992, is dedicated to in-vitro research in restorative dental materials and is open to all TUSDM researchers. The Center is located in DHS 833 and is staffed full-time with a research technician for assistance. The equipment available for use in the Gavel lab includes:
- Instron® 5566A – a universal testing machine that is used to evaluate mechanical properties of materials, including compressive, shear bond, and tensile strength tests.
- EcoMet™ 250 – a grinding machine that uses abrasive paper to expose specimen enamel and/or dentin.
- IsoMet™ 1000 – a precision cutter designed for sectioning various types of materials.
- MicroMet® 2104 – tests Vickers hard ness through micro-indentation.
- VWR™ Thermocycler – mimics the environment of the mouth by transferring samples through hot and cold water baths, simulating material aging.
- Olympus® Crystaleye Spectrophotomer – used in color analysis.
- Orion Star™ A214 – measures solution concentrations of Fluoride and pH.
- Olympus SZX16 – a stereo microscope used for visual analysis.
- High and low speed drill setups – each equipped with an air and water syringe.
Contact the Gavel Center’s technician, Roberta, Afutu (617-636-2115 or Roberta.Afutu@tufts.edu, to schedule lab usage. Institutional Review Board (IRB) clearance and safety training are required before any work can begin.
