Gavel Center
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.
- Wilson VH1202 – Using DiaMet software, assessing the material by Vickers and Knoop microhardness tests.
- VWR™ Thermocycler – mimics the environment of the mouth by transferring samples through hot and cold water baths, simulating material aging.
- Konica Minolta CM-36dGV- benchtop instrument to measure color in reflectance or transmittance with gloss measurement
- 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, Dr. Mona Patel (617-636-0332 or Mona.Patel@tufts.edu), to schedule lab usage. Institutional Review Board (IRB) clearance and safety training are required before any work can begin.
