Researchers develop new material to replace extracted human teeth for dental research

Extracted human teeth have long been used in conducting dental research, such as evaluating dental ceramic materials as a crown restoration on tooth. It is an inexpensive and straightforward process that simulates clinical situations. However, the collection and use of extracted human teeth is becoming increasingly difficult given the concerns about COVID-19, size-standardization issues, and also time constraints. All these factors have prompted a need for dentine analog materials that could potentially substitute extracted human teeth in laboratory-based mechanical and fatigue tests.
