In dentistry, a root pin serves in the retention of artificial teeth. If a tooth has suffered such severe damage by cavities that nothing is left of the crown, crown treatment is no longer be possible, since the crown cannot be securely attached. But if the roots are still intact, then good root canal treatment and restoration of the tooth stump could provide enough support for a crown. Crowns supported by such artificial structures are called pivot crowns.
