Course Contents
- The Clinical and Legal Mythology of Anti-Amalgam
- Myth #1: Amalgams commonly cause fractured cusps.

- Myth #3: Resin composite restorations last as long as amalgam restorations.
- Myth #4: Amalgams cannot be bonded to teeth.
- Myth #5: Because of recent advances in materials and techniques, most studies of composites are outdated; most studies of amalgams are not.
- Myth #6: Resin composites are superior to amalgam because composites can be repaired.
- Myth #7: Amalgam is 100 years old; composite is much newer and therefore better.
- Myth #8: The ADA refuses to admit that mercury-containing amalgam is unsafe for fear of lawsuits.
- Myth #9: The American Dental Association holds the patent on amalgam and receives a royalty on each amalgam placed.
